A 31-year-old homosexual male is complaining of recent weight loss and blurred vision. A fundoscope was performed showing retinal haemorrhage. What is the single most appropriate option?
Your Answer: Cytomegalovirus (CMV)
Explanation:This question presents a 31-year-old homosexual male with symptoms of weight loss and blurred vision, along with retinal hemorrhage seen on fundoscopy. The most likely cause of these symptoms in a patient with HIV is Cytomegalovirus (CMV) infection.
CMV is a common opportunistic infection in individuals with HIV, particularly those with low CD4 counts. It can cause retinitis, leading to retinal hemorrhage and blurred vision. Weight loss is also a common symptom of HIV infection, which can be exacerbated by opportunistic infections like CMV.
The other options listed (Mycobacterium avium, Haemophilus influenzae, NHL, and Pneumocystis jiroveci) are also opportunistic infections commonly seen in HIV patients, but CMV is the most likely cause in this case based on the symptoms provided. Therefore, the single most appropriate option is Cytomegalovirus (CMV).

What is the primary reason for assessing renal function before initiating TDF-containing regimens?
Your Answer: To ensure safe use of TDF without exacerbating renal impairment
Explanation:Assessing renal function before initiating TDF-containing regimens is important because TDF is primarily excreted through the kidneys. If a patient already has impaired renal function, TDF may accumulate in the body and lead to potential toxicity. By assessing renal function before starting TDF, healthcare providers can determine if the patient’s kidneys are functioning well enough to safely metabolize and excrete the drug.
The primary reason for assessing renal function before initiating TDF-containing regimens is to ensure safe use of the drug without exacerbating pre-existing renal impairment. This is important for preventing potential complications and adverse effects that may arise from TDF accumulation in the body. Monitoring renal function allows healthcare providers to adjust the dosage or consider alternative treatment options if necessary to minimize the risk of kidney-related complications.

What is the first step in initiating treatment of a newly diagnosed HIV patient in a primary care setting?
Your Answer: Obtain a detailed patient history and perform a physical examination.
Correct Answer: Follow the NDOH 2020 guidelines for treatment initiation.
Explanation:Steps to manage a patient in primary care:
- Confirm the Diagnosis:
- HIV Testing: Ensure that the HIV diagnosis is confirmed through appropriate testing, typically with two different types of HIV tests to avoid false positives.
- Baseline Assessment:
- Medical History and Physical Examination: Obtain a detailed medical history, including any symptoms, previous illnesses, and risk factors. Conduct a thorough physical examination.
- Baseline Laboratory Tests: These should include:
- CD4 Count: To assess the patient’s immune status.
- Viral Load: To determine the level of HIV in the blood.
- Complete Blood Count (CBC): To check for anemia, leukopenia, or thrombocytopenia.
- Liver and Kidney Function Tests: To evaluate the patient’s overall health and potential contraindications for certain medications.
- Screening for Opportunistic Infections: Tests for tuberculosis, hepatitis B and C, and sexually transmitted infections (STIs).
- Counseling and Education:
- HIV Education: Provide the patient with information about HIV, its transmission, and the importance of adherence to antiretroviral therapy (ART).
- Treatment Expectations: Discuss the benefits and potential side effects of ART.
- Adherence Counseling: Emphasize the importance of taking ART consistently and the impact of adherence on treatment success.
- Disclosure and Support: Offer counseling on the importance of disclosing their HIV status to sexual partners and provide support options.
Once these steps have been taken, one can start initiating treatment.
- Initiate Antiretroviral Therapy (ART):
- Selection of ART Regimen: Follow the national guidelines (NDOH 2020 guidelines for treatment initiation), typically involving a combination of three antiretroviral drugs.
- First-Line Regimen: Common first-line regimens in South Africa may include a combination of Tenofovir (TDF), Lamivudine (3TC), and Dolutegravir (DTG).

A tool known as PrePex™ has been sanctioned by various organizations to reduce the spread of HIV. What is the purpose of this device?
Your Answer: Female condom
Correct Answer: Painless circumcision
Explanation:PrePex Device Offers Painless Male Circumcision for HIV Prevention
The PrePex device is a new method of male circumcision that is painless, sutureless, and does not require anaesthesia. It has been approved in countries such as Rwanda and is currently only available in sub-Saharan Africa. The World Health Organization (WHO) has found scientific evidence that male circumcision can significantly reduce the risk of HIV transmission. As a result, WHO is promoting this strategy in sub-Saharan Africa, where there has been a significant increase in the number of circumcision operations. However, it is important to note that circumcision should be used in conjunction with other measures, such as condom use, to reduce the incidence of HIV infection. The PrePex device is not designed for any other purposes.

Which of the following is the drug of choice for the treatment of Chlamydia trachomatis infection during pregnancy?
Your Answer: Amoxicillin
Explanation:Chlamydia trachomatis is a common sexually transmitted infection that can be passed from mother to baby during childbirth, potentially leading to serious complications for the newborn. Therefore, it is important to treat chlamydia infection in pregnant women to prevent transmission to the baby.
Among the options provided, amoxicillin is the drug of choice for the treatment of Chlamydia trachomatis infection during pregnancy. This is because amoxicillin is considered safe to use during pregnancy and has been shown to be effective in treating chlamydia. Tetracycline, on the other hand, is not recommended in pregnancy due to the risk of harm to fetal development. Metronidazole is not effective against chlamydia, and while it is currently not thought to pose an increased risk in pregnancy, it is not the preferred treatment for chlamydia. Clindamycin and cephazolin are not typically used to treat chlamydia infections.
In conclusion, amoxicillin is the most appropriate choice for treating Chlamydia trachomatis infection in pregnant women due to its safety and effectiveness in this population.

Which of the following is NOT a key adherence message during ART initiation counseling?
Your Answer: Frequency of clinic visits
Explanation:During ART initiation counseling, the healthcare provider typically emphasizes key messages to the patient to ensure successful adherence to their medication regimen. These messages include the risks of poor adherence, the importance of viral load suppression, strategies for missed doses, and methods for storing medication safely.
The frequency of clinic visits is not typically emphasized as a key adherence message during counseling. While it is important for patients to attend their clinic visits regularly for monitoring and support, it is not typically highlighted as a key message during counseling. Instead, the focus is on ensuring that the patient understands the importance of adherence to their medication regimen and has the necessary tools and knowledge to adhere to their treatment plan effectively.

Her parents with a severe headache present a 24-year-old woman. She is afraid of light and sun and prefers darker environments. On examination, a generalized rash that does not blanch on pressure is noticed. What is the best action in this case?
Your Answer: Gown and mask
Correct Answer: IV benzylpenicillin
Explanation:In this case, the best action is to administer IV benzylpenicillin. The patient presents with a severe headache, photophobia, and a non-blanching rash, which are all indicative of meningitis. Meningitis is a serious infection of the protective membranes covering the brain and spinal cord, and requires immediate treatment with antibiotics to prevent complications such as brain damage or death.
Isolating the patient, gowning and masking, and performing a blood culture are important steps in preventing the spread of infection and determining the specific cause of the meningitis. However, the most urgent action in this case is to start IV antibiotics to treat the infection and reduce the risk of serious complications.
A CT Head may be ordered to further evaluate the patient’s symptoms and confirm the diagnosis of meningitis, but starting IV antibiotics should not be delayed while waiting for imaging results. Early treatment is crucial in cases of suspected meningitis to improve outcomes and prevent long-term complications.

A 30-year-old woman presents with a 3-week history of episodes of postcoital bleeding. She has had some lower abdominal pain but no tenderness or urinary symptoms. She is sexually active, with regular periods and her last menstrual cycle was one week ago. Her temperature is 37.1 °C and she has no systemic symptoms. She is a smoker and takes the oral contraceptive pill. Her last smear test was two years ago.
What is the most appropriate initial investigation?Your Answer: Speculum examination of the cervix
Explanation:Postcoital bleeding can be caused by various abnormalities of the cervix, including cervical ectropion, polyps, infection, or cervical cancer. In women presenting with postcoital bleeding, cervical cancer should be suspected if there are other symptoms such as vaginal discharge, pelvic pain, or dyspareunia. Risk factors for cervical cancer include smoking, oral contraceptive use, HPV infection, HIV infection, immunosuppression, and family history.
The primary screening tool for cervical cancer is a cervical smear, which should be done every three years for women aged 25-49. If a patient presents with postcoital bleeding, the first step is to perform a speculum examination to visualize the cervix, which can detect over 80% of cervical cancers. If the cervix appears normal, a smear may be taken if it is due, and swabs can be taken for STI testing and pregnancy testing. If symptoms persist, referral to colposcopy may be necessary.
Other tests such as blood tests, urine dipstick, and high vaginal swab may be useful in certain cases, but they are not the primary investigation for postcoital bleeding. Blood tests may be indicated later, while urine dipstick and high vaginal swab are secondary investigations following visualisation of the cervix.
In summary, speculum examination is the key initial investigation for postcoital bleeding, and cervical smear is the primary screening tool for cervical cancer. Other tests may be useful in specific situations, but they should not replace the essential role of speculum examination and cervical smear in the evaluation of postcoital bleeding.
