During pregnancy which hormone(s) inhibit lactogenesis?
Your Answer: Oestrogen and Progesterone
Explanation:Prolactin levels rise steadily during pregnancy during which time it promotes mammary growth (along with the other hormones mentioned below). Oestrogen and progesterone inhibit lactogenesis and it is only with the loss of these placental steroid hormones at term that Prolactin exhibits its lactogenic effect.

A 28-year-old primigravid woman at 18 weeks of gestation comes to office for a routine prenatal visit and anatomy ultrasound. Patient feels well generally and has no concerns, also has no chronic medical conditions, and her only daily medication is a prenatal vitamin. She is accompanied by her mother as her husband was unable to get off work.Â
Ultrasound shows a cephalic singleton fetus measuring at <10th percentile consistent with severe growth restriction. There are bilateral choroid plexus cysts, clenched fists, and a large ventricular septal defect. Amniotic fluid level is normal with a posterior and fundal placenta.Â
Which of the following statements is the most appropriate initial response by the physician?Your Answer: There are some things about your ultrasound that I need to discuss with you; is it okay to do that now?
Explanation:SPIKES protocol for delivering serious news to patients includes:
– Set the stage includes arranging for a private, comfortable setting space, introduce patient/family & team members, maintain eye contact & sit at the same level and schedule appropriate time interval & minimize space for interruptions.
– Perception: Use open-ended questions to assess the patient’s/family’s perception of the medical situation.
– Invitation: should ask patient/family how much information they would like to know and remain cognizant of their cultural, educational & religious issues.
– Knowledge:
Warn the patient/family that serious news is coming, Speak in simple & straightforward terms, stop & check whether they are understanding.
– Empathy: Express understanding & give support when responding to emotions
– Summary & strategy: Summarize & create follow-through plan, including end-of-life discussions if applicable.The ultrasound findings of severe growth restriction, bilateral choroid plexus cysts, clenched fists, and a large ventricular septal defect are consistent with trisomy 18, the second most common autosomal trisomy, which results in fetal loss or neonatal death in the majority of cases. In this case, the physician is to deliver a very serious news to the patient who is presenting for a routine visit, believing her pregnancy was normal. When serious news is unexpected, it is especially important to prepare the patient and determine how the patient would like to receive the results.
The physician is supposed to provide a comfortable setting and must ask patient’s permission to share the results. This allows the patient to respond with her preference and avoids making assumptions about whom, if anyone, she would like to be present with. For example, some patients may prefer to defer discussion of the results until a major support person (eg, husband, mother) is present. In addition to establish patient’s preferred setting, physician should determine how much information the patient would like to receive. Some patients will prefer a detailed medical information about diagnosis and prognosis, whereas others may prefer to have time to process the news emotionally and receive further information later. The SPIKES protocol (Setting the stage, Perception, Invitation, Knowledge, Empathy, and Summary/strategy) is a six-step model that can guide physicians in delivering serious news to patients.These statements do not allow the patient to choose how she receives the results and assume that she does not want her mother present.
This statement fails to prepare the patient for serious news and prematurely jumps to sharing results using technical, medical terminology that may be difficult for the patient to comprehend. This approach could also be upsetting to a patient undergoing a routine ultrasound who is not expecting anything abnormal.
This statement inappropriately determines when and with whom the patient should receive the results. Instead the patient should be asked how she prefers to receive the results.
While delivering unexpected, serious news, physicians should prepare the patient and determine how the patient prefers to receive the information.

A 31-year-old woman who is pregnant has a blood pressure reading of 160/87 mmHg. You considered Pre-eclampsia. What symptom might be expected in a patient with uncomplicated pre-eclampsia?
Your Answer: Headache
Explanation:Extreme headache, vision defects, such as blurring of the eyes, rib pain, sudden swelling of the face, hands or feet are all consistent with pre-eclampsia. Women with the mentioned symptoms should have their blood pressure checked immediately. They should also be checked for proteinuria.
Diarrhoea is not related to pre-eclampsia. Pruritus would be more related to pregnancy cholestasis. Meanwhile, bruising and abnormal LFTs are common in complicated pre-eclampsia but not in an uncomplicated one.

A 22-year-old nulliparous otherwise healthy woman presents with lower abdominal pain at 16 weeks of gestation. Her body temperature is 37.8 degrees Celsius. She appears to be in good health and is eating properly. Her uterus had been discovered to be retroverted but of normal size at her prior antenatal check at 11 weeks of pregnancy. Which of the following diagnoses is the most likely?
Your Answer: Impaction of a retroverted gravid uterus.
Correct Answer: Urinary tract infection.
Explanation:Lower abdominal pain can be caused by any of the conditions listed in the answers.
A urinary tract infection is the most likely cause.
Unless it was an abdominal ectopic or an interstitial pregnancy, an ectopic pregnancy.
will almost definitely have shown up before the 15th week of pregnancy.
A retroverted gravid uterus may impinge at 15 weeks of pregnancy, however, this is unlikely to be linked to a temperature of 37.8°C.
It’s also possible that it’s the source of acute urine retention.
Complications of the corpus luteum cyst normally manifest themselves considerably earlier in pregnancy, and severe appendicitis is far less likely to be the source of discomfort than a urinary tract infection. -

a 24 year old female patient comes to your office with a chief complaint of painless vaginal bleeding of 1 week duration. She had 3 episodes of bleeding and is on contraceptive pills. Her Pap smear screening is up to date with normal findings.
Which is the cause for her bleeding?Your Answer: A cervical ectropion
Explanation:Cervical ectropion occurs when glandular cells develop on the outside of the cervix. Many individuals with cervical ectropion do not experience symptoms.
However, the primary symptom of cervical ectropion is a red, inflamed patch at the neck of the cervix.
The transformation zone appears this way because the glandular cells are delicate and irritate easily.
Other symptoms a woman may experience include:
pain and bleeding during or after sex
pain during or after cervical screening
light discharge of mucus
spotting between periods
Symptoms may range from mild to severe when they appear.This patient has normal pap smear and is unlikely to have cervical cancer. She has no fever and vaginal discharge which would be the presentation of Chlamydia infection.
Endometrial cancer affects mainly post menopausal women and presents with vaginal bleeding, weight loss, dysuria and dyspareunia.

The main support of the uterus is provided by:
Your Answer: The cardinal ligament
Explanation:The cardinal ligament (or Mackenrodt’s ligament, lateral or transverse cervical ligament) is a major ligament of the uterus. It is located at the base of the broad ligament of the uterus. It attaches the cervix to the lateral pelvic wall by its attachment to the Obturator fascia of the Obturator internus muscle, and is continuous externally with the fibrous tissue that surrounds the pelvic blood vessels. It thus provides support to the uterus.

A 19-year-old female books an appointment at the antenatal clinic at 13 weeks gestation.
One week ago, she had a Papanicolaou (Pap) smear done which showed grade 3 cervical intraepithelial neoplasia (CIN3).
What is the best next step in her management?Your Answer: Colposcopy and large loop excision of the transformation zone (LLETZ biopsy).
Correct Answer: Colposcopy.
Explanation:The best next step in her management is a colposcopy.
Patients diagnosed with high-grade lesions (CIN 2 or 3) or adenocarcinoma in situ (AIS) during pregnancy should undergo surveillance via colposcopy and age-based testing (cytology/HPV) every 12-24 weeks.
Cone biopsy and long loop excision of the transformation zone (LLETZ biopsy) are not recommended if the lesion extends up the canal and out of the vision of the colposcope.
It is not necessary to terminate the pregnancy.Because repeat colposcopic examination during pregnancy offers all of the information needed, the repeat Pap smear is best done after the pregnancy has ended.
Unless colposcopy indicates aggressive cancer at an earlier time, the ultimate therapy required is usually not decided until the postpartum visit.

An HIV positive woman who is 18 weeks pregnant complains of frothy yellow vaginal discharge and vaginal soreness. A wet mount and microscopy confirms a Trichomonas vaginalis infection. Which of the following is the most appropriate treatment regime?
Your Answer: Spiramycin 1.5g BD 14 days
Correct Answer: Metronidazole 500mg BD 7 days
Explanation:Trichomoniasis is considered a sexually transmitted infection found both in men and women caused by the flagellate protozoan Trichomonas vaginalis. The organism is mainly found in the vagina and the urethra. Though many infected women can be asymptomatic, they can also present with yellow frothy vaginal discharge, itching and vaginitis, dysuria or an offensive odour. For the diagnosis of t. vaginalis in women, a swab is taken from the posterior fornix during speculum examination and the flagellates are detected under light-field microscopy. The recommended treatment for t. vaginalis for a HIV positive woman who is pregnant is 500mg of metronidazole twice daily for 7 days. High dose metronidazole as a 2g single dose tablet is not advised during pregnancy. All sexual partners should also be treated, and screening for other STIs should be carried out.

A 48-year-old woman presented to you with a breast mass. On examination, it is hard, irregular and ill defined. The surface of the breast is slightly bruised however, there is no discharge. The most probable diagnosis is?
Your Answer: Ca breast
Correct Answer: Fat necrosis
Explanation:Fat necrosis is often a result of a trauma or surgery. In fat necrosis the enzyme lipase releases fatty acids from triglycerides. The fatty acids combine with calcium to form soaps. These soaps appear as white chalky deposits which are firm lumps with no associated discharge. The given case has a bruise which indicates prior trauma.

A 23-year-old primigravida who is at 41 weeks has been pushing for the past 2 and a half ours. The fetal head is at the introitus and is beginning to crown already. An episiotomy was seen to be necessary. The tear was observed to extend through the sphincter of the rectum but her rectal mucosa remains intact.
Which of the following is the most appropriate type of episiotomy to be performed?Your Answer: Third-degree
Explanation:The episiotomy is a technique originally designed to reduce the incidence of severe perineal tears (third and fourth-degree) during labour. The general idea is to make a controlled incision in the perineum, for enlargement of the vaginal orifice, to facilitate difficult deliveries.
Below is the classification scale for the definitions of vaginal tears:
First degree involves the vaginal mucosa and perineal skin with no underlying tissue involvement.
Second degree includes underlying subcutaneous tissue and perineal muscles.
Third degree is where the anal sphincter musculature is involved in the tear. The third-degree tear can be further broken down based on the total area of anal sphincter involvement.
Fourth degree is where the tear extends through the rectal muscle into rectal mucosa. -

Question 19
Correct

A 50-year-old woman, who had her last menstrual period at age 49, presented with an episode of per vaginal bleeding two weeks ago. It lasted four days in duration. A reduction in the severity of hot flushes as well as some breast enlargement preceded the bleeding episode.
What is the most likely cause of the bleeding?
Your Answer: An episode of ovarian follicular activity.
Explanation:It has been found that it is possible for premenopausal hormones to persist for a period of time after attaining menopause. If one or a few ovarian follicles remain, they could produce oestrogen in response to the very elevated levels of FSH typically seen in menopause. In doing so, the woman can then bleed as a result of this physiological response. The symptoms seen in this vignette are consistent with the rise in oestrogen levels, likely due to follicular activity.
In the absence of any pathological findings such as endometrial carcinoma, this phenomenon would be the most likely cause of this post-menopausal bleed. Furthermore, it is unlikely for cervical cancer and endometrial cancer to present during the first few years following menopause. Atrophic vaginitis is unlikely to be associated with the other symptoms the patient presented with i.e. reduction in the intensity of hot flushes and breast enlargement. This patient was not stated to have any risk factors for endometrial hyperplasia such as obesity, late menopause and early menarche, which makes it a less likely diagnosis.

A 35-year-old female patient, gravida 1 para 1, visits the clinic to have her contraception method evaluated. The patient has had unpredictable bleeding for the past 8 months since receiving a subdermal progestin implant and begs that it be removed. She used to use combined oral contraceptives and would like to go back to it. The patient has primary hypertension, which she was diagnosed with last year and is effectively controlled on hydrochlorothiazide. She does not take any other medications or have any allergies. Her father and brother both suffer from type 2 diabetes. The patient does not smoke, drink, or use illegal drugs.
24 kg/m2 is her BMI. Blood pressure is 130/75 millimetres of mercury. Physical examinations are all normal. Which of the following is increased by using combination oral contraceptives?Your Answer: Breast fibroadenoma
Correct Answer: Worsening hypertension
Explanation:Overt hypertension, developing in about 5% of Pill users, and increases in blood pressure (but within normal limits) in many more is believed to be the result of changes in the renin-angiotensin-aldosterone system, particularly a consistent and marked increase in the plasma renin substrate concentrations. The mechanisms for the hypertensive response are unclear since normal women may demonstrate marked changes in the renin system. A failure of the kidneys to fully suppress renal renin secretion could thus be an important predisposing factor. These observations provide guidelines for the prescription of oral contraceptives. A baseline blood pressure measurement should be obtained, and blood pressure and weight should be followed at 2- or 3-month intervals during treatment. Oral contraceptive therapy should be contraindicated for individuals with a history of hypertension, renal disease, toxaemia, or fluid retention. A positive family history of hypertension, women for whom long-term therapy is indicated, and groups such as blacks, especially prone to hypertensive phenomena, are all relative contraindications for the Pill.
COCs do not increase the risk of developing breast and endometrial cancer, Type 2 DM or breast fibroadenoma.

You're looking after a 24-year-old woman who is experiencing pelvic pain. She has one-sided pain that is widespread and mild, but can be intense at times. Menstruation has been regular. She denies having fever.
With the exception of a smooth movable adnexal mass on the right side, her pelvic examination seems normal.
Which of the following is the most likely reason for your discomfort?Your Answer: Ovarian cyst
Explanation:An ovarian cyst is a sac filled with liquid or semiliquid material that arises in an ovary. Although the discovery of an ovarian cyst causes considerable anxiety in women owing to fears of malignancy, the vast majority of these lesions are benign. Most patients with ovarian cysts are asymptomatic, with the cysts being discovered incidentally during ultrasonography or routine pelvic examination. Some cysts, however, may be associated with a range of symptoms, sometimes severe, including the following:
Pain or discomfort in the lower abdomen
Severe pain from torsion (twisting) or rupture – Cyst rupture is characterized by sudden, sharp, unilateral pelvic pain; this can be associated with trauma, exercise, or coitus. Cyst rupture can lead to peritoneal signs, abdominal distention, and bleeding (which is usually self-limited)
Discomfort with intercourse, particularly deep penetration
Changes in bowel movements such as constipation
Pelvic pressure causing tenesmus or urinary frequency
Menstrual irregularities
Precocious puberty and early menarche in young children
Abdominal fullness and bloating
Indigestion, heartburn, or early satiety
Endometriomas – These are associated with endometriosis, which causes a classic triad of painful and heavy periods and dyspareunia
Tachycardia and hypotension – These may result from haemorrhage caused by cyst rupture
Hyperpyrexia – This may result from some complications of ovarian cysts, such as ovarian torsion
Adnexal or cervical motion tendernessUnderlying malignancy may be associated with early satiety, weight loss
achexia, lymphadenopathy, or shortness of breath related to ascites or pleural effusionThe absence of fever or vaginal discharge rules out PID
The absence of pain on the right lower quadrant, fever, nausea and vomiting rule out appendicitis.
The patient has regular menses, no vaginal bleeding no signs of shock that rules out ectopic pregnancy.
her symptoms are also not consistent with the presentation of leiomyoma. Leiomyoma presents with enlarged uterus, pelvic pressure. It early causes pain when it is complicated with red degeneration which usually occurs in pregnancy.

A 23-year-old gravida 1 para 0 at 36 weeks gestation presents to the office complaining of ankle swelling and occasional headache for the past 2 days. She denies any abdominal pain or visual disturbances. On examination you note a fundal height of 35 cm, a fetal heart rate of 140 beats/min, 2+ lower extremity oedema, and a blood pressure of 144/92 mm Hg. A urine dipstick shows 1+ proteinuria.
Which one of the following is the most appropriate next step in the management of this patient?Your Answer: Initiation of antihypertensive treatment
Correct Answer: Laboratory evaluation, fetal testing, and 24-hour urine for total protein
Explanation:This patient most likely has preeclampsia, which is defined as an elevated blood pressure and proteinuria after 20 weeks gestation. The patient needs further evaluation, including a 24-hour urine for quantitative measurement of protein, blood pressure monitoring, and laboratory evaluation that includes haemoglobin, haematocrit, a platelet count, and serum levels of transaminase, creatinine, albumin, LDH, and uric acid- A peripheral smear and coagulation profiles also may be obtained- Antepartum fetal testing, such as a nonstress test to assess fetal well-being, would also be appropriate.
→ Ultrasonography should be done to assess for fetal intrauterine growth restriction, but only after an initial laboratory and fetal evaluation.
→ It is not necessary to start this patient on antihypertensive therapy at this point. An obstetric consultation should be considered for patients with preeclampsia.
→ Delivery is the definitive treatment for preeclampsia- The timing of delivery is determined by the gestational age of the foetus and the severity of preeclampsia in the mother. Vaginal delivery is preferred over caesarean delivery, if possible, in patients with preeclampsia. -

A 30-year-old primigravida woman presented to the clinic for her first antenatal check-up. Upon interview, it was noted that she was taking folic acid along with some other nutritional supplements as medication.
All of the following are considered correct regarding neural tube defects and folate before and during pregnancy, except:Your Answer: Prevalence of neural tube defects among non-indigenous population is almost double than that in Aboriginal and Torres Strait Islander babies
Explanation:Neural tube defects (NTDs) are common complex congenital malformations resulting from failure of the neural tube closure during embryogenesis. It is established that folic acid supplementation decreases the prevalence of NTDs, which has led to national public health policies regarding folic acid.
Neural tube defects (NTD) were 43% more common in Indigenous than in non-Indigenous infants in Western Australia in the 1980s, and there has been a fall in NTD overall in Western Australia since promotion of folate and voluntary fortification of food has occurred.
Women should take 5 mg/d of folic acid for the 2 months before conception and during the first trimester.
Women planning pregnancy might be exposed to medications with known antifolate activities affecting different parts of the folic acid metabolic cascade. A relatively large number of epidemiologic studies have shown an increased risk of NTDs among babies exposed in early gestation to antiepileptic drugs (carbamazepine, valproate, barbiturates), sulphonamides, or methotrexate. Hence, whenever women use these medications, or have used them near conception, they should take 5 mg/d of folic acid until the end of the first trimester of pregnancy.

Which of the following conditions has the best prognosis for infertility treatment?Your Answer: Stein-Leventhal syndrome
Explanation:Approximately 75–80% of patients with PCOS will ovulate after Clomiphene citrate. Although there appears to be discrepancy between ovulation and pregnancy rates, life-table analysis of the largest and most reliable studies indicates a conception rate of up to 22% per cycle in those ovulating on CC.
Pelvic TB causes tubal occlusion by scarring leading to infertility. Once occlusion occurs, IVF is usually the only option for conception. This is also the case for women with Turner syndrome.
Azoospermia maybe treated with surgery or hormonal therapy based on the cause but the success rate is low.

A 28-year-old woman presented with nausea and vomiting along with headache during pregnancy. She also has a past medical history of a migraine.
What among the following will be the most appropriate management in this case?Your Answer: Codein and promethazine
Explanation:This patient should be given promethazine and codeine as she presents with severe migraine.
Usage of metoclopramide is safe during pregnancy and for increasing effectiveness it can be added to paracetamol. However, because of its risk for causing extrapyramidal effects it should be used only as a second-line therapy and Promethazine should be considered as the first line choice of remedy. So the answer is Codeine and promethazine.
Opioid pain relievers such as codeine are not been reported of having any associated with increased birth defects or miscarriage, but its long-term use can lead to dependency in mother and withdrawal signs in the baby.
Paracetamol alone or combined with codeine is not found to be useful in controlling vomiting.
It is advised to completely avoid dihydroergotamine and the triptans throughout pregnancy.

– Posterior wall: formed by the transversalis fascia; its medial part is reinforced by pubic attachments of the internal oblique and transversus abdominis aponeuroses that frequently merge to variable extents into a common tendon—the inguinal falx (conjoint tendon)—and the reflected inguinal ligament.
– Roof: formed laterally by the transversalis fascia, centrally by musculo-aponeurotic arches of the internal oblique and transversus abdominis, and medially by the medial crus of the external oblique aponeurosis.
– Floor: formed laterally by the iliopubic tract, centrally by gutter formed by the infolded inguinal ligament, and medially by the lacunar ligament. -

A patient with amenorrhoea is seen in clinic. History and examination reveal the patient runs 10-20 miles every day and her BMI is 17.8. Which of the following is likely to explain her symptoms?
Your Answer: WHO type I Ovulation Disorders
Explanation:World Health Organization (WHO) Group I ovulation disorder is due to hypothalamic pituitary failure. This is sometimes termed hypothalamic amenorrhoea or hypogonadotropic hypogonadism. Women can improve frequency of ovulation, conception and an uncomplicated pregnancy by increasing their body weight (if BMI of <19) and/or moderating their exercise levels (if they undertake high levels of exercise). GnRH and LH may be administered in these patients. PCOS falls under type II ovulation disorders. WHO Group III ovulation disorder is due to ovarian failure.

A 44-year-old lady came to the clinic with a five-year history of urine incontinence. With a BMI of 34, she is fat. Her last child, weighing 4.2 kg, was born six years ago.
She has been using various over-the-counter medicines to treat constipation and gastric reflux for the past three years. She is a non-smoker with normal blood pressure.
Which of the following is not a risk factor for female urinary incontinence development?Your Answer: Gastro-oesophageal reflux disease
Explanation:Stress UI (SUI) is more common among puerperal women, followed by mixed UI (MUI) and urge UI (UUI). Generally, episodes of urine leakage are infrequent and the amount of urine leakage is small.
Maternal age greater than 35 years, UI during pregnancy, elevated body mass index (BMI), multiparity, and normal birth are considered risk factors for postpartum UI. A 10-year cohort study developed with the goal of assessing the effect of the first normal birth on urinary symptoms showed that it was associated with an increase in SUI, in addition to UUI, regardless of maternal age or number of births.
Other factors such as: colour or race, episiotomy, perineal tears, newborn’s head circumference, newborn’s weight, gestational age at birth, smoking, and constipation require further studies in order to prove their association with postpartum UI.

A 33-year-old female patient walks into your office to speak with you about her recent pap smear result. A low-grade squamous intraepithelial lesion was discovered (LSIL). Her most recent pap smear, performed two years ago, came back normal.
Which of the following is the most appropriate course of action?Your Answer: Repeat the pap smear in one year
Explanation:An LSIL Pap test shows mild cellular changes. The risk of a high-grade cervical precancer or cancer after an LSIL Pap test is as high as 19 percent.
As with an ASC-US Pap test, an LSIL Pap test is evaluated differently depending upon age.
For women ages 25 or older, follow-up depends upon the results of human papillomavirus (HPV) testing:
– Women who test positive for HPV or who have not been tested for HPV should have colposcopy.
– Women who test negative for HPV can be followed up with a Pap test and HPV test in one year.Referring the patient to an oncologist is not acceptable since there is no established diagnosis of malignancy that has been made. All other options are unacceptable since Pap smear must be done in 12 months.

One week after the delivery of her baby at the 38th week of pregnancy, a 33-year-old woman developed deep vein thrombosis (DVT). She has been on enoxaparin therapy for DVT. Upon discharge, there is a plan to start her on warfarin. When this was explained, the patient was reluctant to take warfarin since she thinks it might cause problems to the baby because she is planning to breastfeed.
Which of the following is considered correct regarding warfarin and breastfeeding?Your Answer: She should continue to breastfeed her baby while she is on warfarin
Explanation:No adverse reactions in breastfed infants have been reported from maternal warfarin use during lactation, even with a dose of 25 mg daily for 7 days. There is a consensus that maternal warfarin therapy during breastfeeding poses little risk to the breastfed infant.

Regarding missed abortion, all of the following are CORRECT, EXCEPT:
Your Answer: Immediate evacuation should be done once the diagnosis is made
Explanation:Expectant management has been reported with unpredictable success rate ranging from 25–76%. Waiting for spontaneous expulsion of the products of conception would waste much time, during which women may suffer uncertainty and anxiety. However, when additional surgical evacuation is needed owing to failure, they may suffer from an emotional breakdown. It is thus not recommended for missed early miscarriage due to the risks of emergency surgical treatment and blood transfusion.

A 34 week pregnant patient complains of itching over the past 6 weeks particularly to the hands and feet which is worse at night. You order some blood tests. Which of the following would you normally expect to increase in the 3rd trimester?
Your Answer: ALP
Explanation:Pruritus of pregnancy is a common disorder, which occurs in 1 in 300 pregnancies, and presents as excoriated papules on extensor limbs, abdomen
and shoulders. It is more common in women with a history of atopy. Prurigo usually starts at around 25–30 weeks of pregnancy and resolves after delivery,
with no effect on the mother or baby. Treatment is symptomatic with topical steroids and emollients. It occurs due to derangement in the LFTs. ALP can rise to up to 3 times the normal non-pregnant value in the 3rd trimester.
All of the other tests above typically decrease during pregnancy. -

Among the following which is the most likely finding of placental abruption in a pregnant woman?
Your Answer: Vaginal bleeding
Explanation:Placental abruption is defined as the premature separation of placenta from uterus and the condition usually presents with bleeding, uterine contractions and fetal distress. It is one of the most significant cause of third-trimester bleeding and is often associated with fetal and maternal mortality and morbidity. In all pregnant women with vaginal bleeding in the second half of the pregnancy, this condition should be considered as a differential diagnoses.
Though vaginal bleeding is the most common presenting symptom reported by almost 80% of women with placental abruption, vaginal bleeding is concealed in 20% of women with placental abruption, therefore, absence of vaginal bleeding does not exclude placental abruption.Symptoms and complications of placental abruption varies according to patient, frequency of appearance of some common features is as follows:
‌- Vaginal bleeding is the common presentation in 80% of patients.
‌- Abdominal or lower back pain with uterine tenderness is found in 70%
‌- Fetal distress is seen in 60% of women.
‌- Abnormal uterine contractions like hypertonic, high frequency contractions are seen in 35% cases.
‌- Idiopathic premature labor in 25% of patients.
‌- Fetal death in about 15% of cases.Examination findings include vaginal bleeding, uterine contractions with or without tenderness, shock, absence of fetal heart sounds and increased fundal height due to an expanding hematoma. Shock is seen in class 3 placental abruption which represents almost 24% of all cases of placental abruption.

All of the following are considered complications of gestational trophoblastic disease, except:
Your Answer: Pre-eclampsia
Correct Answer: Infertility
Explanation:Gestational trophoblastic disease (GTD) is a group of tumours defined by abnormal trophoblastic proliferation. Trophoblast cells produce human chorionic gonadotropin (hCG).
GTD is divided into hydatidiform moles (contain villi) and other trophoblastic neoplasms (lack villi). The non-molar or malignant forms of GTD are called gestational trophoblastic neoplasia (GTN).
Hydatidiform mole (HM) is associated with abnormal gametogenesis and/or fertilization. Risk factors include extremes of age, ethnicity, and a prior history of an HM which suggests a genetic basis for its aetiology.GTD is best managed by an interprofessional team that includes nurses and pharmacists. Patients with molar pregnancies must be monitored for associated complications including hyperthyroidism, pre-eclampsia, and ovarian theca lutein cysts. Molar pregnancy induced hyperthyroidism should resolve with the evacuation of the uterus, but patients may require beta-adrenergic blocking agents before anaesthesia to reverse effects of thyroid storm. Pre-eclampsia also resolves quickly after the evacuation of the uterus. Theca lutein cysts will regress spontaneously with falling beta-HCG levels. However, patients must be counselled on signs and symptoms of ovarian torsion and ruptured ovarian cysts.
A single uterine evacuation has no significant effect on future fertility, and pregnancy outcomes in subsequent pregnancies are comparable to that of the general population, despite a slight increased risk of developing molar pregnancy again.

Question 47
Correct

A 34-year-old woman, gravida 1 para 1, presented to the emergency department complaining of left breast pain six weeks after a spontaneous, uncomplicated term vaginal delivery. She reported having noticed the pain and redness on her left breast a week ago. From her unaffected breast, she continued to breastfeed her infant.
Upon history taking, it was noted that she has no chronic medical conditions and for medication, she only takes a daily multivitamin. Her temperature was taken and the result was 38.3 deg C (101 deg F).
Further observation was done and the presence of an erythematous area surrounding a well-circumscribed, 4-cm area of fluctuance extending from the areola to the lateral edge of the left breast was noted. There was also the presence of axillary lymphadenopathy.
Which of the following is the next step to best manage the condition of the patient?Your Answer: Needle aspiration and antibiotics
Explanation:Breast infections can be associated with superficial skin or an underlying lesion. Breast abscesses are more common in lactating women but do occur in nonlactating women as well.
The breast contains breast lobules, each of which drains to a lactiferous duct, which in turn empties to the surface of the nipple. There are lactiferous sinuses which are reservoirs for milk during lactation. The lactiferous ducts undergo epidermalization where keratin production may cause the duct to become obstructed, and in turn, can result in abscess formation. Abscesses associated with lactation usually begin with abrasion or tissue at the nipple, providing an entry point for bacteria. The infection often presents in the second postpartum week and is often precipitated in the presence of milk stasis. The most common organism known to cause a breast abscess is S. aureus, but in some cases, Streptococci, and Staphylococcus epidermidis may also be involved.
The patient will usually provide a history of breast pain, erythema, warmth, and possibly oedema. Patients may provide lactation history. It is important to ask about any history of prior breast infections and the previous treatment. Patients may also complain of fever, nausea, vomiting, purulent drainage from the nipple, or the site of erythema. It is also important to ask about the patient’s medical history, including diabetes. The majority of postpartum mastitis are seen within 6 weeks of while breast-feeding
The patient will have erythema, induration, warmth, and tenderness to palpation at the site in question on the exam. It may feel like there is a palpable mass or area of fluctuance. There may be purulent discharge at the nipple or site of fluctuance. The patient may also have reactive axillary adenopathy. The patient may have a fever or tachycardia on the exam, although these are less common.
Incision and drainage are the standard of care for breast abscesses. If the patient is seen in a primary care setting by a provider that is not comfortable in performing these procedures, the patient may be started on antibiotics and referred to a general surgeon for definitive treatment. Needle aspiration may be attempted for abscesses smaller than 3 cm or in lactational abscesses. A course of antibiotics may be given before or following drainage of breast abscesses.

Question 48

A 37-year-old woman has been taking Microgynon (oral contraceptive pill [OCP]).
When she presents for a repeat prescription, her BP is 160/100 mmHg.
She mentions that she would like to stop the OCP in six months so that she can conceive.
What is the most suitable advice for this woman?Your Answer: Continue the OCP unchanged, but add methyldopa as a hypotensive agent, as this could be continued during a subsequent pregnancy.
Correct Answer: Cease the OCP, use condoms for contraception, and reassess the BP in three months.
Explanation:The woman’s blood pressure was elevated at her visit; therefore she should be advised to immediately cease the oral contraceptive pill (OCP) so that the hypertension can resolve without the need for any hypotensive treatment. The blood pressure can then be reassessed in three months. Alternative, non-hormonal birth control methods such as condoms should be used instead.
If her high blood pressure does not resolve, any medication that would be commenced to reduce her blood pressure should be one that is safe to continue when she becomes pregnant.
It is inappropriate to continue the OCP even at a lower dosage or in combination with a hypotensive agent.
Methyldopa has been evaluated and used for treatment of hypertension during pregnancy. There is no clinical evidence to suggest that it causes harm to the foetus or neonate.
Angiotensin converting enzyme (ACE) inhibitors are not approved for use in pregnancy as they have been associated with fetal death in utero. Other antihypertensive agents such as beta-blockers and diuretics are also problematic in pregnancy and should be avoided.

A 30-year-old woman in her 36 weeks of gestation, presents for her planned antenatal appointment.
On examination her blood pressure is 150/90 mmHg, in two consecutive readings 5 minutes apart.
Which among the following statements is true regarding gestational hypertension and pre-eclampsia?Your Answer: Pre-eclampsia involves other features in addition to the presence of hypertension
Explanation:Pre-eclampsia presents with other features in addition to the presence of hypertension, also it’s diagnosis cannot be made considered peripheral edema as the only presenting symptom. Proteinuria occurs more commonly in pre-eclampsia than in gestational hypertension and the latter is mostly asymptomatic.
Hypertensive disorders are found to complicate about 10% of all pregnancies. Common one among them is Gestational hypertension, which is defined as the new onset of hypertension after 20 weeks of gestation without any maternal or fetal features of pre-eclampsia, in this case BP will return to normal within three months of postpartum.
Types of hypertensive disorders during pregnancy:
1. Pregnancy-induced hypertension:
a. Systolic blood pressure (SBP) above 140 mm of Hg and diastolic hypertension above 90 mmHg occurring for the first time after the 20th week of pregnancy, which regresses postpartum.
b. The rise in systolic blood pressure above 25 mm of Hg or diastolic blood pressure above 15 mm of Hg from readings before pregnancy or in the first trimester.
2. Mild pre-eclampsia:
BP up to 170/110 mm of Hg in the absence of associated features.
3. Severe pre-eclampsia:
BP above 170/110 mm of Hg and along with features such as kidney impairment, thrombocytopenia, abnormal liver transaminase levels, persistent headache, epigastric tenderness or fetal compromise.
4. Essential (coincidental) hypertension:
Chronic underlying hypertension occurring before the onset of pregnancy or persisting after postpartum.
5. Pregnancy-aggravated hypertension:
Underlying hypertension which is worsened by pregnancy.To diagnose pre-eclampsia clinically, presence of one or more of the following symptoms are required along with a history of onset of hypertension after 20 weeks of gestation.
– Proteinuria: Above 300 mg/24 h or urine protein
reatinine ratio more than 30 mg/mmol.
– Renal insufficiency: serum/plasma creatinine above 0.09 mmol/L or oliguria.
– Liver disease: raised serum transaminases and severe epigastric or right upper quadrant pain.
– Neurological problems: convulsions (eclampsia); hyperreflexia with clonus; severe headaches with hyperreflexia; persistent visual disturbances (scotomata).
– Haematological disturbances like thrombocytopenia; disseminated intravascular coagulation; hemolysis. -

Among the following, which is the most common method used for termination of a pregnancy before 20 weeks in Australia?
Your Answer: Comobined mifepristone and misoprostol
Correct Answer: Suction and curettage
Explanation:Medical abortion is preferred from 4 to 9 weeks of gestation and in Australia, suction curettage is the most frequently used method of abortion as it is considered useful from 6 to 14 weeks of gestation.
Mifepristone is a synthetic anti-progesterone, which is found to be effective for abortion when combined with misoprostol. There are evidences which suggest the effectiveness of misoprostol and mifepristone in both first and second trimesters. It is most commonly administered as a single dose of mifepristone followed by misoprostol, a prostaglandin, given orally or vaginally two days later. Prostaglandin can be repeated at an interval of 4 hours if required.
As the vaginal use shows only few gastrointestinal side effects Misoprostol is more effective and better tolerated vaginally than orally. Misoprostol is not approved for its use in termination of pregnancy, but is available in the market due to its indications in other conditions.
Methotrexate can be used orally or as an intramuscular injection followed by misoprostol up to seven days later, but this also is not a preferred method for termination of pregnancy in Australia. -
