Question 3 of 5
A 52-year-old woman suffering from hypertension still had a blood pressure of 156/92 mm Hg after 3 months of therapy with hydrochlorothiazide and losartan. Her physician decided to add a third drug that acts by decreasing central sympathetic outflow. Which of the following adverse effects was most likely to occur after a few days of therapy with the new drug?
Correct Answer: A
Rationale: The most likely adverse effect to occur after adding a third drug that acts by decreasing central sympathetic outflow would be severe postural hypotension. This is due to the combined effect of the drugs leading to a significant drop in blood pressure upon standing up, causing dizziness and potential fainting episodes. This adverse effect is commonly associated with antihypertensive medications that affect sympathetic outflow.
Question 4 of 5
Which of the following actions most likely mediated the therapeutic effect of nitrates in the patient's disease?
Correct Answer: B
Rationale: Nitrates, such as nitroglycerin and isosorbide mononitrate, mediate their therapeutic effect in variant angina by increasing blood flow in large epicardial vessels. This vasodilatory effect helps improve oxygen delivery to the heart muscle, relieving angina symptoms. Other options like increased heart rate, cardiac contractility, or left ventricular end-diastolic volume are not the primary mechanisms of action for nitrates in this context.
Question 5 of 5
Exertion-induced angina, which is relieved by rest, nitroglycerin, or both, is referred to as
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
