Question 1 of 5
Tick the drugs for the treatment of an intestinal form of amebiasis:
Correct Answer: A
Rationale: The correct answer is A: Metronidazole and diloxanide. Metronidazole is effective against the invasive form of Entamoeba histolytica, the parasite causing amebiasis. Diloxanide is used to eliminate the non-invasive cyst form of the parasite in the intestine. Streptomycin (choice B) is not effective against amebiasis. Iodoquinol (choice C) is used for non-invasive amebiasis but not the intestinal form. Emetine (choice D) is reserved for extraintestinal disease and is not commonly used due to its toxicity.
Question 2 of 5
This drug acts on acetylcholine-sensitive K+ channels.
Correct Answer: B
Rationale: The correct answer is B: Verapamil. Verapamil is a calcium channel blocker that acts on acetylcholine-sensitive K+ channels, leading to smooth muscle relaxation and vasodilation. Digoxin (A) acts on cardiac muscle by inhibiting the sodium-potassium pump. Propranolol (C) is a beta-blocker that acts on beta-adrenergic receptors. Procainamide (D) is a Class I antiarrhythmic agent that blocks sodium channels. Thus, Verapamil is the correct choice based on its mechanism of action on acetylcholine-sensitive K+ channels.
Question 3 of 5
Which of the following therapeutic changes would be most appropriate for the patient diagnosed with variant angina?
Correct Answer: B
Rationale: The correct answer is B: Add nitroglycerin to the therapeutic regimen. Nitroglycerin is a standard treatment for variant angina as it helps dilate blood vessels, increasing blood flow to the heart. This can help relieve chest pain associated with the condition. Choice A is incorrect as nifedipine and propranolol are both used to treat angina, but nifedipine is not specifically indicated for variant angina. Choice C is incorrect as captopril is an ACE inhibitor used for hypertension and heart failure, not specifically for variant angina. Choice D is incorrect as nifedipine and hydrochlorothiazide are both used for hypertension but not specifically for variant angina.
