Diltiazem (Cardizem) has been prescribed for a patient newly diagnosed with Prinzmetal’s (variant) angina. What accurate action of diltiazem should the nurse include in the teaching plan?

It increases the contractile force of the heart.

It reduces heart palpitations.

It decreases coronary artery spasms.

It prevents the formation of plaque in the coronary arteries.

Answer and Explanation

The Correct Answer is C

Choice A rationale
Diltiazem does not increase the contractile force of the heart. In fact, it is classified as a negative inotrope, meaning it decreases the force of heart contractions.
Choice B rationale
While diltiazem can affect heart rhythm, it does not specifically reduce heart palpitations. Its primary effect is to slow the heart rate and relax the blood vessels.
Choice C rationale
Diltiazem is a calcium channel blocker used to manage cardiovascular conditions such as hypertension, chronic stable angina, atrial fibrillation, and Prinzmetal’s angina. It works by inhibiting the calcium influx into cardiac and vascular smooth muscle during depolarization. This results in vasodilation, or the widening of blood vessels, which can help decrease coronary artery spasms, a characteristic feature of Prinzmetal’s angina.
Choice D rationale
Diltiazem does not prevent the formation of plaque in the coronary arteries. It primarily acts to relax the blood vessels and slow the heart rate.

Correct Answer is D

Explanation

Choice A rationale
Sinus tachycardia at a rate of 110 beats/min is a normal response to exercise. During a stress test, the heart rate will naturally increase as the body’s demand for oxygen increases. A heart rate of 110 beats/min is within the expected range during moderate exercise.
Choice B rationale
An increase in blood pressure from 134/68 to 150/80 mm Hg is a normal response to exercise. During a stress test, blood pressure will naturally rise as the heart works harder to pump blood to the muscles. This increase is within the expected range during moderate exercise.
Choice C rationale
Feeling tired during a stress test on a treadmill is a normal response to exercise. Fatigue can occur as the body’s energy stores are used up during physical activity. However, if the patient reports extreme fatigue or other symptoms such as chest pain or shortness of breath, it may indicate a problem.
Choice D rationale
Inversion of T waves on the electrocardiogram during a stress test is a sign of myocardial ischemia, a condition in which the heart muscle is not getting enough oxygen. This could indicate the presence of significant coronary artery disease and is a finding that would necessitate immediate action.

A. Skin hyperpigmentation. B. Gangrene. C. Edema above the knee. D. Deep vein thrombus formation.

Correct Answer is A

Explanation

Choice A rationale
Skin hyperpigmentation is a common symptom of chronic venous insufficiency. This happens because blood pools in the veins and can leak into the surrounding tissue, causing a change in skin color.
Choice B rationale
Gangrene is not a typical symptom of chronic venous insufficiency. Gangrene is a serious condition that occurs when tissue dies due to a lack of blood flow.
Choice C rationale
Edema, or swelling, is a common symptom of chronic venous insufficiency, but it typically occurs in the lower legs and ankles, not above the knee.
Choice D rationale
Deep vein thrombus formation is not a typical symptom of chronic venous insufficiency. However, a history of deep vein thrombosis can increase the risk of developing chronic venous insufficiency.
