Question 1 of 5
Tick the drug used for trypanosomosis treatment:
Correct Answer: A
Rationale: The correct answer is A: Melarsoprol. Melarsoprol is an arsenical compound used specifically for the treatment of trypanosomosis, caused by Trypanosoma parasites. It is effective in treating both forms of the disease, African trypanosomiasis (sleeping sickness) and American trypanosomiasis (Chagas disease). Metronidazole (B) is used for treating anaerobic bacterial infections, not trypanosomiasis. Tetracycline (C) is an antibiotic effective against a wide range of bacterial infections, but not against trypanosomiasis. Quinidine (D) is used to treat malaria and certain heart rhythm disorders, but not trypanosomiasis.
Question 2 of 5
Which of the following drugs was most likely added to the patient's therapy resulting in his present complaint?
Correct Answer: C
Rationale: The correct answer is C: Verapamil. Verapamil is a calcium channel blocker that can cause constipation, which is a common complaint in patients. Hydralazine (A) can cause reflex tachycardia, Propranolol (B) is a beta-blocker that can cause bradycardia, and Clonidine (D) is an alpha-2 agonist that can cause hypotension. Therefore, based on the patient's complaint of constipation, Verapamil is the most likely drug added to the patient's therapy.
Question 3 of 5
Which of the following would be an appropriate therapeutic adjustment for the 65-year-old man with acute distress and cardiac failure?
Correct Answer: D
Rationale: The correct answer is D because discontinuing digoxin and starting losartan is the appropriate therapeutic adjustment for a 65-year-old man with acute distress and cardiac failure. Digoxin is not recommended in the acute phase of heart failure as it can worsen symptoms. Losartan, an angiotensin II receptor blocker, is beneficial in heart failure by improving outcomes and reducing hospitalizations. Discontinuing digoxin eliminates the risk of toxicity and adverse effects. Other choices are incorrect because adding potassium supplementation (Choice A) can increase the risk of hyperkalemia, adding atropine (Choice B) is not indicated in heart failure, and increasing furosemide dose (Choice C) may lead to electrolyte imbalances without addressing the underlying cause.
