Cardiovascular Drug Therapy Questions
Question 1 of 5
All of the following agents are the first-line antimycobacterial drugs EXCEPT:
Correct Answer: D
Rationale: The correct answer is D: Streptomycin. First-line antimycobacterial drugs are those recommended as initial treatment for Mycobacterium tuberculosis infections. Streptomycin is considered a second-line drug due to its potential for serious side effects and development of resistance. Rifampin, Pyrazinamide, and Isoniazid are all first-line drugs supported by extensive clinical evidence and are preferred for initial therapy. Streptomycin is reserved for cases where first-line drugs are contraindicated or ineffective. Therefore, choosing Streptomycin as the correct answer is logical based on its classification as a second-line antimycobacterial drug.
Question 2 of 5
Which of the following drugs was most likely included in the therapeutic regimen of this patient?
Correct Answer: C
Rationale: The correct answer is C: Furosemide. Furosemide is a loop diuretic commonly used to treat conditions such as edema and hypertension. In this case, the patient likely required a strong diuretic to manage fluid overload, which is best achieved with a loop diuretic like furosemide. Hydrochlorothiazide (A) is a thiazide diuretic, which is less potent than loop diuretics like furosemide. Mannitol (B) is an osmotic diuretic used for conditions such as cerebral edema and not typically included in routine therapeutic regimens. Fenoldopam (D) is a selective dopamine receptor agonist used for acute hypertension but is not commonly included in routine diuretic regimens like furosemide.
Question 3 of 5
Which of the following drugs most likely caused the patient's MI?
Correct Answer: A
Rationale: The correct answer is A: Propranolol. Propranolol is a non-selective beta-blocker that can potentially cause vasoconstriction, increased blood pressure, and decreased oxygen supply to the heart, leading to myocardial infarction (MI) in susceptible individuals. Nitroprusside (B) and Nitroglycerin (C) are vasodilators that help improve blood flow and decrease cardiac workload, making them unlikely to cause MI. Nifedipine (D) is a calcium channel blocker that primarily affects blood vessels and the heart, but it is less likely to cause MI compared to propranolol.
