Question 1 of 5
Tick the indications for nitrofuranes:
Correct Answer: B
Rationale: The correct answer is B: Infections of urinary and gastrointestinal tracts. Nitrofuranes are commonly used to treat urinary tract infections and certain gastrointestinal infections due to their effectiveness against a variety of bacteria commonly found in these areas. Nitrofuranes are not typically used to treat respiratory infections (choice A), syphilis (choice C), or tuberculosis (choice D) as there are more appropriate antibiotics available for these conditions. Therefore, choice B is the correct indication for nitrofuranes based on their spectrum of activity and clinical effectiveness.
Question 2 of 5
Which of the following best explains the reason for his anginal episodes?
Correct Answer: B
Rationale: Step 1: Nitroglycerin is a vasodilator commonly used to relieve angina symptoms. Step 2: Cellular tolerance can develop with prolonged nitroglycerin use, reducing its effectiveness. Step 3: In this case, the patient's anginal episodes suggest a diminished response to nitroglycerin. Step 4: This is supported by the fact that increasing metabolism (Choice C) or insufficient dosage (Choice D) would not explain the reduced efficacy. Step 5: Vasospasm (Choice A) would be less likely as the primary cause compared to cellular tolerance.
Question 3 of 5
Which of the following pairs of drugs were most likely administered?
Correct Answer: B
Rationale: The correct answer is B, Diazoxide and hydralazine. Diazoxide is a vasodilator used to treat hypertension emergencies, while hydralazine is also a vasodilator commonly used for hypertensive crises. Both drugs have fast-acting properties and are often administered together to rapidly reduce blood pressure. A (Labetalol and prazosin) is incorrect because Labetalol is a beta-blocker and prazosin is an alpha-blocker, which are not commonly administered together for hypertensive emergencies. C (Clonidine and captopril) is incorrect because Clonidine is a centrally acting alpha-2 agonist and captopril is an ACE inhibitor, which are not typically used together for acute hypertension. D (Nitroprusside and esmolol) is incorrect because Nitroprusside is a potent vasodilator and esmolol is a beta-blocker, but they are not usually administered together
