Question 2 of 5
A man has been searching for an aphrodisiac or some other agent to enhance 'sexual performance' discovers yohimbine. He consumes the drug in excess and develops symptoms of toxicity that require your intervention. Which of the following should you expect as a response to this drug?
Correct Answer: D
Rationale: The correct answer is D: Hypertension. Yohimbine is a known alpha-2 adrenergic antagonist, leading to increased sympathetic activity and consequently, hypertension. This occurs due to increased norepinephrine release and vasoconstriction. Bradycardia (A) is unlikely as yohimbine usually causes tachycardia. Bronchoconstriction (B) is not a common effect of yohimbine. Excessive secretions by exocrine glands (C) are not associated with yohimbine toxicity.
Question 3 of 5
This is a strange day for you in the emergency department. Now you have to treat another normovolemic patient with acute drug-induced hypotension, and give the usually correct and effective dose of phenylephrine. This time the drug causes a vasopressor response that is far greater than you've ever encountered: systolic pressure rises dramatically, if not dangerously. Which of the following drugs did the patient most likely take an overdose of?
Correct Answer: D
Rationale: The correct answer is D: Reserpine. Reserpine is a drug that depletes catecholamines like norepinephrine and dopamine from nerve endings, leading to a prolonged and exaggerated response to sympathomimetic drugs like phenylephrine. This results in a dramatic increase in blood pressure when phenylephrine is given. Rationale: 1. Atenolol (A) is a beta-blocker and would not lead to a vasopressor response. 2. Bethanechol (B) is a cholinergic agonist and would not lead to a vasopressor response. 3. Prazosin (C) is an alpha-1 adrenergic antagonist and would not lead to a vasopressor response. In summary, Reserpine is the correct answer because it depletes catecholamines, leading to an exaggerated response to sympathomimetic drugs like phenylephrine, resulting in

Dopamine intravenous infusion is used in the treatment of:
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
Which of the following drugs selectively stimulates β2 adrenoceptors:
Correct Answer: D
Rationale: The correct answer is D: Salbutamol. Salbutamol is a selective β2 adrenoceptor agonist. It has a higher affinity for β2 receptors compared to β1 receptors, leading to bronchodilation without significant effects on the heart. A: Adrenaline and C: Isoprenaline stimulate both β1 and β2 receptors, causing increased heart rate and bronchodilation. B: Noradrenaline stimulates α1, α2, and β1 receptors, leading to vasoconstriction and increased heart rate. Therefore, salbutamol is the only drug that selectively stimulates β2 adrenoceptors, making it the correct choice.
