Question 1 of 5
A nurse is caring for a client that is newly diagnosed with hypertension. Which of the following medications is a beta-adrenergic blocker that has a mechanism of action to decrease heart rate, myocardial contractility, and cardiac output, and is also used to treat hypertension?
Correct Answer: A
Rationale:
Correct Answer: A. Metoprolol is a beta-adrenergic blocker that decreases heart rate, myocardial contractility, and cardiac output. It is commonly used to treat hypertension by reducing the workload on the heart. This medication works by blocking the effects of adrenaline on beta-adrenergic receptors in the heart and blood vessels. This results in a decrease in heart rate and blood pressure, ultimately helping to manage hypertension. Metoprolol is a first-line treatment for hypertension due to its effectiveness in reducing cardiovascular risk.
Incorrect
Choices:
B: Nitroglycerin is a vasodilator used to treat angina by dilating blood vessels, not specifically for hypertension.
C: Losartan is an angiotensin II receptor blocker used to treat hypertension by blocking the effects of angiotensin II, not a beta-adrenergic blocker.
D: Metformin is an anti-diabetic medication used to treat type 2 diabetes, not hypertension.
