Correct Answer is D

Explanation

Choice A rationale
Atrial Flutter is a type of arrhythmia where the atria beat regularly, but much faster than usual. The treatment for Atrial Flutter is typically medication, not cardioversion.
Choice B rationale
Ventricular Tachycardia is a fast, abnormal heart rate. It starts in your heart’s lower chambers, or ventricles. Ventricular Tachycardia is a serious condition and can be life-threatening. While cardioversion can be used in some cases, it is not the primary treatment.
Choice C rationale
Atrial Fibrillation is when the upper chambers of the heart (atria) beat irregularly. This causes the atria to twitch, leading to an abnormal heart rhythm. The treatment for Atrial Fibrillation is typically medication, not cardioversion.
Choice D rationale
Ventricular Fibrillation is a life-threatening heart rhythm that results in a rapid, erratic heartbeat. During Ventricular Fibrillation, the heart quivers and can’t pump any blood, causing cardiac arrest. The treatment for Ventricular Fibrillation is Defibrillation.

A. Decreased blood pressure. B. Decreased urine output. C. Increased appetite. D. Increased fluid retention.

Correct Answer is A

Explanation

Choice A rationale
Vasotec, an Angiotensin-Converting Enzyme (ACE) inhibitor, is commonly used to treat conditions like high blood pressure and heart failure. It works by relaxing blood vessels, which allows blood to flow more easily and reduces blood pressure.
Choice B rationale
Decreased urine output is not a typical outcome of taking Vasotec. In fact, ACE inhibitors like Vasotec can sometimes increase urine output by improving kidney function.
Choice C rationale
Increased appetite is not a known effect of Vasotec. If a patient experiences a significant change in appetite while taking this medication, they should consult their healthcare provider.
Choice D rationale
Increased fluid retention is not a typical outcome of taking Vasotec. ACE inhibitors like Vasotec are often used to help reduce fluid retention in patients with conditions like heart failure.
