    Correct

    • A well recognised adverse effect of metoclopramide is which of the following?

      Your Answer: Acute dystonic reaction

      Explanation:

      Side effects of metoclopramide are commonly associated with extrapyramidal effects and hyperprolactinemia. Therefore its use must be limited to short-term use. Metoclopramide can induce acute dystonic reactions which involve facial and skeletal muscle spasms and oculogyric crises. These dystonic effects are more common in the young girls and young women, and in the very old. These symptoms usually occur shortly after starting treatment with this drug and subside within 24 hours of stopping it. Abortion of dystonic attacks can be carried out by injection of an antiparkinsonian drug like procyclidine.

    Incorrect

    • On ambulatory blood pressure monitoring, a 48-year-old Caucasian man has an average BP reading of 152/96 mmHg (ABPM).

      Which of the following would be the patient's first-line drug treatment?

      Your Answer: No medication is required at this stage

      Correct Answer: Ramipril

      Explanation:

      An ambulatory blood pressure reading of >150/95 is classified as stage 2 hypertension, according to the NICE care pathway for hypertension, and the patient should be treated with an antihypertensive drug.

      A calcium-channel blocker, such as amlodipine, would be the most appropriate medication for a 48-year-old Afro-Caribbean man.

      An ACE inhibitor, such as ramipril, or a low-cost angiotensin-II receptor blocker (ARB), such as losartan, would be the most appropriate medication for a 48-year-old Caucasian man.

    Incorrect

    • A 60-year-old man comes to your department with complaints of epigastric pain. There is a history of rheumatoid arthritis and he has been taking ibuprofen 200 mg TDS for the last 2 weeks.

      The following scenarios would prompt you to consider the co-prescription of a PPI for gastroprotection with NSAIDs EXCEPT?

      Your Answer: Co-prescription of fluoxetine

      Correct Answer: Long-term use for chronic back pain in a patient aged 30

      Explanation:

      The current recommendations by NICE suggest that gastro-protection should be considered if patients have ≥1 of the following:

      Aged 65 or older
      – Using maximum recommended dose of an NSAID
      – History of peptic ulcer or GI bleeding
      – Concomitant use of: antidepressants like SSRIs and SNRIs, Corticosteroids, anticoagulants and low dose aspirin
      – Long-term NSAID usage for: long-term back pain if older than 45 and patients with OA or RA at any age

      The maximum recommended dose of ibuprofen is 2.4 g daily and this patient is on 400 mg of ibuprofen TDS.

    Correct

    • A 60-year-old female has a past medical history of diverticular disease. She now presents in the clinic with crampy abdominal pain. The nurse at the triage suggests prescribing hyoscine butyl bromide to help relieve the abdominal pain. However, after administering this treatment, the patient develops a side-effect to the medication.

      What side-effect of using hyoscine butyl bromide is she MOST likely to develop out of the following?

      Your Answer: Dry mouth

      Explanation:

      Hyoscine butylbromide is an antispasmodic drug that blocks muscarinic receptors and reduces intestinal motility. It is used for gastrointestinal and genitourinary smooth muscle spasms and symptomatic relief of IBS.

      It has the following side-effects:
      1. Constipation
      2. Dizziness
      3. Drowsiness
      4. Dry mouth

      Your Answer:

      Correct Answer: Tachycardia

      Explanation:

      Juxtapulmonary or ‘J’ receptors are located on alveolar and bronchial walls close to the capillaries. Their afferents are small unmyelinated C-fibres or myelinated nerves in the vagus nerve. Activation causes depression of somatic and visceral activity by producing apnoea or rapid shallow breathing, a fall in heart rate and blood pressure, laryngeal constriction and relaxation of skeletal muscles via spinal neurones. J receptors are stimulated by increased alveolar wall fluid, pulmonary congestion and oedema, microembolism and inflammatory mediators. J receptors are thought to be involved in the sensation of dyspnoea in lung disease.

    • Regarding amoxicillin, which of the following statements is INCORRECT:

      Your Answer:

      Correct Answer: It is used first line for bacterial tonsillitis.

      Explanation:

      Amoxicillin is a derivative of ampicillin and has a similar antibacterial spectrum. It is better absorbed than ampicillin when given orally, producing higher plasma and tissue concentrations; unlike ampicillin, absorption is not affected by the presence of food in the stomach.

      The adverse effects of amoxicillin are mainly gastrointestinal and mild and include nausea, vomiting and diarrhoea. Amoxicillin is used first line for low to moderate severity community acquired pneumonia, exacerbations of chronic bronchitis, for acute otitis media, for acute sinusitis, for oral infections/dental abscess, for Listeria meningitis (in combination with another antibiotic), for infective endocarditis (in combination with another antibiotic) and for H. Pylori eradication (in combination with metronidazole/clarithromycin and a PPI).

      Penicillin V is used first line for bacterial tonsillitis; amoxicillin should be avoided in blind treatment of a sore throat as there is a high risk of a rash if glandular fever is present.

      Your Answer:

      Correct Answer: The blood-brain barrier is freely permeable to HCO3 - ions.

      Explanation:

      CSF is separated from the blood by the blood-brain barrier. This barrier is impermeable to polar molecules such as H+and HCO3-but CO2can diffuse across it easily. The pH of CSF is therefore determined by the arterial PCO2and the CSF HCO3-and is not affected by blood pH.

    • A 36 year old man who is overweight with a history of gout, presents to emergency room with an acutely painful big toe which is red, hot and swollen. However, he is apyrexic and otherwise systemically well. He has been diagnosed with acute gout. The most appropriate first line treatment for him is which of the following?

      Your Answer:

      Correct Answer: NSAIDs

      Explanation:

      The first line treatment for acute gout includes NSAIDs like diclofenac, indomethacin or naproxen. In patients in whom NSAIDs are contraindicated, not tolerated or ineffective, colchicine is an alternative. In those who cannot tolerate or who are resistant to NSAIDs and colchicine, oral or parenteral corticosteroids are an effective alternative. In acute monoarticular gout, intra-articular injection of a corticosteroid can be used occasionally. In acute gout. allopurinol is not used in the actual treatment, but its use should be continued during an acute attack if the patient is already established on long term therapy.

    • Regarding loop diuretics, which of the following statements is INCORRECT:

      Your Answer:

      Correct Answer: The risk of hypokalaemia is greater with loop diuretics than with an equipotent dose of a thiazide diuretic.

      Explanation:

      Hypokalaemia can occur with both thiazide and loop diuretics. The risk of hypokalaemia depends on the duration of action as well as the potency and is thus greater with thiazides than with an equipotent dose of a loop diuretic. Hypokalaemia is dangerous in severe cardiovascular disease and in patients also being treated with cardiac glycosides. Often the use of potassium-sparing diuretics avoids the need to take potassium supplements. In hepatic failure, hypokalaemia caused by diuretics can precipitate encephalopathy, particularly in alcoholic cirrhosis.

    • A 45-year-old man, a known case of epilepsy, visits his neurologist with complaints of red, swollen gums.

      Which of the following medications is most likely responsible for his symptoms?

      Your Answer:

      Correct Answer: Phenytoin

      Explanation:

      Phenytoin is a commonly used antiepileptic drug. A well-recognized side-effect of phenytoin is gingival enlargement and occurs in about 50% of patients receiving phenytoin. It is believed that reduced folate levels may cause this, and evidence suggests that folic acid supplementation may help prevent this in patients starting phenytoin.

      As evidence suggests, drug-induced gingival enlargement may also improve by substituting with other anticonvulsant drugs and reinforcing a good oral hygiene regimen. Surgical excision of hyperplastic gingiva is often necessary to correct the aesthetic and functional impairment associated with this condition to manage it successfully.

      Phenytoin is also the only anticonvulsant therapy associated with the development of Dupuytren’s contracture.
      Other side effects are:
      1. Ataxia
      2. Drug-induced lupus
      3. Hirsutism
      4. Pruritic rash
      5. Megaloblastic anaemia

    Incorrect

    • A 59-year-old man presents to the emergency room with chest pain. The cardiology team recently discharged him. He underwent a procedure and was given several medications, including abciximab, during his stay. Which of the following statements about abciximab is correct?

      Your Answer:

      Correct Answer: It is a glycoprotein IIa/IIIb receptor antagonist

      Explanation:

      Abciximab (ReoPro) is a glycoprotein IIb/IIIa receptor antagonist that is a chimeric monoclonal antibody. It is primarily used during and after coronary artery procedures such as angioplasty to inhibit platelet aggregation.

      It’s approved for use as a supplement to heparin and aspirin in high-risk patients undergoing percutaneous transluminal coronary intervention to prevent ischaemic complications. Only one dose of abciximab should be given (to avoid additional risk of thrombocytopenia).

      Before using, it is recommended that baseline prothrombin time, activated clotting time, activated partial thromboplastin time, platelet count, haemoglobin, and haematocrit be measured. 12 and 24 hours after starting treatment, haemoglobin and haematocrit should be measured again, as should platelet count 2-4 hours and 24 hours after starting treatment.
      When used for high-risk patients undergoing angioplasty, the EPIC trial(link is external)found that abciximab reduced the risk of death, myocardial infarction, repeat angioplasty, bypass surgery, and balloon pump insertion.

      The use of abciximab is contraindicated in the following situations:
      Internal bleeding is present.
      Within the last two months, you’ve had major surgery, intracranial surgery, or trauma.
      Stroke in the previous two years
      Intracranial tumour
      Aneurysm or arteriovenous malformation
      Haemorrhagic diathesis is a type of haemorrhagic diathesis.
      Vasculitis
      Retinopathy caused by hypertension

      The following are some of the most common abciximab side effects:
      Manifestations of bleeding
      Bradycardia
      Back ache
      Pain in the chest
      Vomiting and nausea
      Pain at the puncture site

    Incorrect

    • A 4-year-old child has been convulsing for 20 minutes. She has received two doses of lorazepam. She takes phenytoin for maintenance therapy, and you draw up a phenobarbitone infusion.
      What dose of phenobarbitone is advised in the treatment of the convulsing child that reaches that stage of the APLS algorithm? Select ONE answer only.

      Your Answer:

      Correct Answer: 20 mg/kg over 30-60 minutes

      Explanation:

      If a convulsing child reaches step 3 of the APLS algorithm, then a phenytoin infusion should be set up at 20 mg/kg over 20 minutes. If they are already taken phenytoin as maintenance therapy, then a phenobarbitone infusion should be set up at 20 mg/kg over 30-60 minutes.

    Incorrect

    • In patients requiring oxygen, who are at risk of hypercapnic respiratory failure, oxygen saturations should be maintained at:

      Your Answer:

      Correct Answer: 88 - 92%

      Explanation:

      A lower target of 88 – 92% oxygen saturation is indicated for patients at risk of hypercapnic respiratory failure e.g. patients with COPD. Until blood gases can be measured, initial oxygen should be given using a controlled concentration of 28% or less, titrated towards the SpO2 of 88 – 92%. The aim is to provide the patient with enough oxygen to achieve an acceptable arterial oxygen tension without worsening carbon dioxide retention and respiratory acidosis.

    Incorrect

    • A 25-year-old female arrives at the emergency room with a severe case of asthma. When she doesn't seem to be improving after initial treatment, you decide to start an aminophylline infusion.

      From the options below, which is Aminophylline's main mechanism of action?

      Your Answer:

      Correct Answer: Phosphodiesterase inhibition

      Explanation:

      Theophylline and Ethylenediamine are combined in a 2:1 ratio to form Aminophylline. Its solubility is improved by the addition of Ethylenediamine. It has a lower potency and a shorter duration of action than Theophylline.
      It is used to treat the following conditions:
      Heart failure
      It is used to treat the following conditions:
      COPD
      Bradycardias

      Aminophylline has the following properties:
      Phosphodiesterase inhibitor that increases intracellular cAMP and relaxes smooth muscle in the bronchial airways and pulmonary blood vessels.
      Mast cell stabilization is achieved by using a non-selective adenosine receptor antagonist.
      It has slight positive inotropic and chronotropic effects, increasing cardiac output and decreasing systemic vascular resistance, lowering arterial blood pressure. It has been used historically in the treatment of refractory heart failure and is indicated by the current ALS guidelines as a substitute treatment for bradycardia.

      The daily oral dose for adults is 900 mg, divided into 2-3 doses. For severe asthma or COPD, a loading dosage of 5 mg/kg over 10-20 minutes is given, followed by a continuous infusion of 0.5 mg/kg/hour. The therapeutic range is small (10-20 microgram/ml), hence assessments of aminophylline plasma concentrations are useful during long-term treatment.

    Incorrect

    • An ambulance transports a 72-year-old woman to the Emergency Department. She is confused, has been vomiting and having stomach pains. Digoxin is one of her medications.

      Which of the following claims about digoxin is correct?

      Your Answer:

      Correct Answer: Therapeutic plasma levels are between 1.0-1.5 nmol/l

      Explanation:

      Digoxin is a cardiac glycoside that is used to treat atrial fibrillation and flutter, as well as congestive heart failure. In cardiac myocytes, it works by inhibiting the membrane Na/K ATPase. Through Na/Ca exchange, this raises intracellular sodium concentration and indirectly increases intracellular calcium availability. Increased intracellular calcium levels have both a positive inotropic and negative chronotropic effect.

      Digoxin therapeutic plasma levels are typically between 1.0 and 1.5 nmol/l, though higher concentrations may be required, and the value varies between laboratories. At concentrations greater than 2 nmol/l, the risk of toxicity increases dramatically.

      In patients with normal renal function, digoxin has a long plasma half-life of 36 to 48 hours. This can take up to 5 days in patients with impaired renal function.

      Hypokalaemia, rather than hyperkalaemia, has been shown to increase the risk of digoxin toxicity.

      In the treatment of persistent and permanent atrial fibrillation, digoxin is no longer widely used. Beta-blockers, also known as rate-limiting calcium channel blockers, are now the first-line treatment for this condition.

    • A 29-year-old man is diagnosed with a severe case of asthma.

      In the treatment of acute asthma in adults, which of the following is NOT recommended?

      Your Answer:

      Correct Answer: Nebulised magnesium

      Explanation:

      There is no evidence to support the use of nebulized magnesium sulphate in the treatment of adults at this time.

      In adults with acute asthma, the following medication dosages are recommended:
      By using an oxygen-driven nebuliser, you can get 5 milligrams of salbutamol.
      500 mcg ipratropium bromide in an oxygen-driven nebuliser
      Oral prednisolone 40-50 mg
      100 mg hydrocortisone intravenous
      1.2-2 g magnesium sulphate IV over 20 minutes
      When inhaled treatment is ineffective, intravenous salbutamol (250 mcg IV slowly) may be explored (e.g. a patient receiving bag-mask ventilation).

      Following senior counsel, current ALS recommendations propose that IV aminophylline be explored in severe or life-threatening asthma. If utilized, a loading dose of 5 mg/kg should be administered over 20 minutes, then a 500-700 mcg/kg/hour infusion should be given. To avoid toxicity, serum theophylline levels should be kept below 20 mcg/ml.

      Your Answer:

      Correct Answer: Erythromycin

      Explanation:

      Bacteriostatic antibiotics include erythromycin and other macrolides.

    Incorrect

    • Regarding dynamic compression of the airways, which of the following statements is CORRECT:

      Your Answer:

      Correct Answer: It occurs during forced expiration.

      Explanation:

      Dynamic compression occurs because as the expiratory muscles contract during forced expiration, all the structures within the lungs, including the airways, are compressed by the positive intrapleural pressure. Consequently the smaller airways collapse before the alveoli empty completely and some air remains within the lungs (the residual volume). Physiologically this is important as a completely deflated lung with collapsed alveoli requires significantly more energy to inflate. Dynamic compression does not occur in normal expiration because the intrapleural pressure is negative throughout the whole cycle.

    Incorrect

    • You review a 46-year-old woman who has recently been prescribed antibiotics for a urinary tract infection. She suffers from COPD and is currently prescribed salbutamol and Seretide inhalers, and Phyllocontin continus. Since starting the antibiotics, she has been experiencing nausea, vomiting and abdominal pain.
      Which of the following antibiotics is she MOST LIKELY to have been prescribed for her UTI? Select ONE answer only .

      Your Answer:

      Correct Answer: Ciprofloxacin

      Explanation:

      Phyllocontin continus contains aminophylline (a mixture of theophylline and ethylenediamine), a bronchodilator used in the management of COPD and asthma.
      This patient is exhibiting symptoms of theophylline toxicity, which may have been triggered by the prescription of the antibiotic. Quinolone antibiotics, such as ciprofloxacin and levofloxacin, and macrolide antibiotics, such as erythromycin, increase the plasma concentration of theophyllines and can lead to toxicity.
      The drugs that commonly affect the half-life and the plasma concentration of theophylline are summarised in the table below:
      Drugs increasing plasma concentration of theophylline
      Drugs decreasing plasma concentration of theophylline
      Calcium channel blockers, e.g. Verapamil
      Cimetidine
      Fluconazole
      Macrolides, e.g. erythromycin
      Quinolones, e.g. ciprofloxacin
      Methotrexate
      Barbiturates
      Carbamazepine
      Phenobarbitol
      Phenytoin (and fosphenytoin)
      Rifampicin

    Incorrect

    • You're a member of the cardiac arrest team, and you're helping to resuscitate an elderly gentleman who had collapsed at home. The team leader requests that you administer an adrenaline shot.

      Which of the following statements about adrenaline is FALSE?

      Your Answer:

      Correct Answer: The IM dose in anaphylaxis is 1 ml of 1:1000

      Explanation:

      Adrenaline (epinephrine) is a sympathomimetic amine that binds to alpha- and beta-adrenergic receptors and acts as an agonist. It is active at both alpha and beta receptors in roughly equal amounts.

      When taken orally, it becomes inactive. Subcutaneous absorption is slower than intramuscular absorption. In cardiac arrest, it is well absorbed from the tracheal mucosa and can be given through an endotracheal tube.

      At the adrenergic synapse, catechol-O-methyltransferase (COMT) and monoamine oxidase (MAO) metabolise it primarily. The inactive products are then passed through the kidneys and excreted in the urine.

      In adult cardiac arrest, the IV dose is 1 mg, which is equal to 10 ml of 1:10000 or 1 ml of 1:1000. In anaphylaxis, the IM dose is 0.5 ml of 1:1000. (500 mcg).

      In open-angle glaucoma, adrenaline causes mydriasis and lowers pressure.

      Adrenaline is used in cardiopulmonary resuscitation, the treatment of severe croup, and the emergency management of acute allergic and anaphylactic reactions (as a nebuliser solution).

    Incorrect

    • You review a 34-year-old man with lower back pain and plan to prescribe him ibuprofen and codeine phosphate. His only past medical history of note is depression, for which he takes fluoxetine.
      Which of the following scenarios would prompt you to consider the co-prescription of a PPI for gastro-protection? Select ONE answer only.

      Your Answer:

      Correct Answer: Co-prescription of fluoxetine

      Explanation:

      Patients at risk of gastro-intestinal ulceration (including the elderly) who need NSAID treatment should receive gastroprotective treatment. The current recommendations by NICE suggest that gastro-protection should be considered if patients have ≥1 of the following:
      Using maximum recommended dose of an NSAID
      Aged 65 or older
      History of peptic ulcer or GI bleeding
      Concomitant use of medications that increase risk:
      Low dose aspirin
      Anticoagulants
      Corticosteroids
      Anti-depressants including SSRIs and SNRIs
      Requirements for prolonged NSAID usage:
      Patients with OA or RA at any age
      Long-term back pain if older than 45
      It is suggested that if required, either omeprazole 20 mg daily or lansoprazole 15-30 mg daily should be the PPIs of choice.
      This patient is on 400 mg of ibuprofen TDS, but the maximum recommended dose of ibuprofen is 2.4 g daily. Co-prescription of codeine, raised BMI, and a family history of peptic ulceration would also not prompt gastro-protection.

    Incorrect

    • You're called to a cardiac arrest in your Emergency Department resuscitation area. The rhythm strip is shown in the diagram below. Defibrillation has already been attempted three times on the patient. You intended to administer amiodarone, but your department has informed you that it is not available. In these circumstances, if amiodarone is not available, which of the following drugs is recommended by the ALS guidelines? Ventricular fibrillation

      Your Answer:

      Correct Answer: Lidocaine

      Explanation:

      If amiodarone is unavailable in VF/pVT arrests, lidocaine at a dose of 1 mg/kg can be used instead, according to the latest ALS guidelines. If amiodarone has already been given, no lidocaine should be given.
