Question 1 of 5

The nurse is educating a client prior to an electrocardiogram (ECG). What is the best explanation regarding the purpose of electrocardiography?

Correct Answer: B

Rationale: An electrocardiogram assesses the heart's electrical activity, helping diagnose arrhythmias, myocardial infarction, and other cardiac conditions.

Question 2 of 5

A patient with a history of hypertension treated with a diuretic and an angiotensin-converting enzyme (ACE) inhibitor arrives in the emergency department complaining of headache and blurred vision and has a blood pressure (BP) of 192/108 mmHg. Which question should the nurse ask to follow up on these findings?
