Question 1 of 5
A nurse is caring for a client who has an elevated potassium level and is on a cardiac monitor. The nurse is aware that hyperkalemia may be associated with changes to the T-wave. On the graphic, point and click on the area of the electrocardiogram (ECG) that represents the T wave.
Correct Answer: A
Rationale: The T wave, representing ventricular repolarization, is the prominent upward wave following the QRS complex. Hyperkalemia may cause tall, peaked T waves.
Question 2 of 5

Question 3 of 5
A nurse is caring for a client who is taking enalapril (Vasotec). Which of the following outcomes indicates a therapeutic effect of the medication?
Correct Answer: D
Rationale: Enalapril, an ACE inhibitor, lowers blood pressure by preventing vasoconstriction and reducing fluid retention. It does not directly treat claudication or affect cholesterol levels.
Question 4 of 5
The nurse is assessing a client diagnosed with peripheral arterial disease (PAD). The client reports leg pain and cramping after walking a few blocks, which is relieved when the client stops and rests. The nurse documents that the client is experiencing which clinical manifestation?
Correct Answer: D
Rationale: Intermittent claudication is pain/cramping with activity that resolves with rest, due to reduced blood flow in PAD. Neuropathy causes numbness/tingling, venous insufficiency causes swelling, and DVT causes unilateral pain/swelling.
