Cardiac Disorders NCLEX Questions

Extract:

Question 1 of 5

An adult is diagnosed with hypertension. He is prescribed chlorothiazide (Diuril) 500 mg PO. What nursing instruction is essential for him?

Correct Answer: C

Rationale: Chlorothiazide, a diuretic, can cause potassium loss. Consuming potassium-rich foods like orange juice or bananas helps prevent hypokalemia.

Question 2 of 5

Which data would cause the nurse to question administering digoxin to a client diagnosed with congestive heart failure?

A. The potassium level is 3.2 mEq/L. B. The digoxin level is 1.2 mcg/mL. C. The client's apical pulse is 64. D. The client denies yellow haze.

Correct Answer: A

Rationale: Hypokalemia (K+ 3.2,
A) increases digoxin toxicity risk, warranting caution. Digoxin level 1.2 (
B) is therapeutic, pulse 64 (
C) is normal, and no yellow haze (
D) is expected.

Question 3 of 5

A. The client has a history of coronary artery disease (CAD). B. The client has a history of diabetes insipidus (DI). C. The client has a history of chronic obstructive pulmonary disease (COPD). D. The client has a history of multiple fractures from a motor-vehicle accident.

Correct Answer: A

Rationale: CAD (
A) directly impairs cardiac perfusion due to atherosclerosis, an antecedent to perfusion issues. DI (
B), COPD (
C), and fractures (
D) are less directly related.

Question 4 of 5

Which nursing action would best reduce the client's energy, the client?

A. Administering oxygen when the client is dyspneic B. Staggering self-care activities over several hours C. Providing analgesic medications when necessary D. Restricting visitors to brief periods of time

A. The client is free from chest pain. B. The client's heart rate remains regular. C. The client moves the operative leg easily. D. The client's heart rate remains regular.
