- A. Amiodarone
- B. Adenosine
- C. Verapamil
- D. Digoxin
Explanation: Amiodarone is used for shock-refractory ventricular fibrillation or pulseless ventricular tachycardia during cardiac arrest.
Correct answer: Amiodarone- A. Calcium gluconate
- B. Sodium bicarbonate
- C. Furosemide
- D. Oral potassium chloride
Explanation: Intravenous calcium gluconate stabilizes the myocardium during severe hyperkalaemia with ECG changes, but it does not remove potassium…
Correct answer: Calcium gluconate- A. Magnesium sulfate
- B. Calcium chloride
- C. Atropine sulfate
- D. Procainamide
Explanation: Intravenous magnesium sulfate is the standard emergency treatment for torsades de pointes, even when the serum magnesium level is not yet…
Correct answer: Magnesium sulfate- A. Vitamin K
- B. Protamine sulfate
- C. Naloxone
- D. Desmopressin
Explanation: Vitamin K restores production of vitamin K dependent clotting factors and reverses warfarin effect, although its action is not immediate.
Correct answer: Vitamin K- A. Glucagon
- B. Flumazenil
- C. Methylene blue
- D. Pyridoxine
Explanation: Glucagon can improve heart rate and contractility in significant beta blocker toxicity because it increases intracellular cyclic AMP…
Correct answer: Glucagon- A. Pyridoxine
- B. Folic acid
- C. Vitamin K
- D. Calcium gluconate
Explanation: Isoniazid toxicity is treated with pyridoxine, also called vitamin B6, because isoniazid depletes active pyridoxine and promotes seizures.
Correct answer: Pyridoxine- A. Intravenous lipid emulsion
- B. Intravenous vitamin K
- C. Oral activated charcoal alone
- D. Intravenous acetylcysteine
Explanation: Intravenous lipid emulsion is used in severe local anaesthetic systemic toxicity, together with airway support and seizure management.
Correct answer: Intravenous lipid emulsion- A. Sodium bicarbonate
- B. Calcium gluconate
- C. Naloxone
- D. Atropine sulfate
Explanation: Intravenous sodium bicarbonate alkalinises serum and urine, increasing salicylate ionisation and renal elimination.
Correct answer: Sodium bicarbonate- A. Methylene blue
- B. Hydroxocobalamin
- C. Protamine sulfate
- D. Glucagon
Explanation: Methylene blue reduces methemoglobin back to functional haemoglobin and is commonly used when symptoms are significant.
Correct answer: Methylene blue- A. Dobutamine
- B. Furosemide
- C. Lidocaine
- D. Adenosine
Explanation: Dobutamine is an inotropic medicine that increases myocardial contractility and can improve cardiac output in cardiogenic shock.
Correct answer: Dobutamine- A. Magnesium sulfate
- B. Vitamin K
- C. Protamine sulfate
- D. Calcium carbonate
Explanation: Intravenous magnesium sulfate can relax bronchial smooth muscle in severe asthma that responds poorly to initial treatment.
Correct answer: Magnesium sulfate- A. Intravenous calcium
- B. Intravenous vitamin K
- C. Oral activated charcoal alone
- D. Intravenous methylene blue
Explanation: Intravenous calcium can improve myocardial contractility and vascular tone in serious calcium channel blocker poisoning.
Correct answer: Intravenous calcium- A. High-flow oxygen
- B. Intramuscular atropine
- C. Oral naloxone
- D. Intravenous iron
Explanation: High-flow oxygen helps displace carbon monoxide from haemoglobin and should be started promptly when carbon monoxide poisoning is…
Correct answer: High-flow oxygen- A. Fomepizole
- B. Deferoxamine
- C. Protamine sulfate
- D. N-acetylcysteine
Explanation: Fomepizole inhibits alcohol dehydrogenase and reduces the formation of toxic methanol metabolites.
Correct answer: Fomepizole- A. Protect the airway before charcoal
- B. Give charcoal with fruit juice
- C. Induce vomiting before charcoal
- D. Place the patient flat and give charcoal
Explanation: Airway protection comes first because charcoal can be aspirated by a patient who cannot swallow safely or protect the airway.
Correct answer: Protect the airway before charcoal- A. Acute withdrawal and seizures
- B. Severe hypoglycaemia
- C. Irreversible kidney failure
- D. Profound platelet destruction
Explanation: Flumazenil can precipitate acute benzodiazepine withdrawal, including agitation and seizures, especially in dependent patients or mixed…
Correct answer: Acute withdrawal and seizures- A. Intravenous dextrose
- B. Intramuscular vitamin K
- C. Oral glucose tablets
- D. Subcutaneous insulin
Explanation: Intravenous dextrose is appropriate for an unconscious patient with confirmed intravenous access because it raises blood glucose rapidly.
Correct answer: Intravenous dextrose- A. Hydrocortisone
- B. Furosemide
- C. Digoxin
- D. Warfarin
Explanation: Hydrocortisone may be used as an adjunct in severe allergic reactions, although its onset is slower than adrenaline.
Correct answer: Hydrocortisone- A. Fomepizole
- B. Atropine
- C. Calcium gluconate
- D. Pralidoxime
Explanation: Fomepizole blocks alcohol dehydrogenase and limits production of toxic ethylene glycol metabolites.
Correct answer: Fomepizole- A. Octreotide
- B. Hydrocortisone
- C. Glucagon
- D. Calcium gluconate
Explanation: Octreotide suppresses pancreatic insulin release and is used for recurrent sulfonylurea-induced hypoglycaemia.
Correct answer: Octreotide
