Cardiovascular Nursing Questions Questions
Question 1 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. The patient reports a severe headache and nausea and has a blood pressure(BP) of 238/118 mm Hg. Which question should the nurse ask to follow up on these findings?
Correct Answer: B
Rationale: Sudden withdrawal of antihypertensive medications can cause rebound hypertension and hypertensive crisis. Although many over-the-counter medications can cause hypertension, antihistamines and acetaminophen do not increase BP. Stressful events will increase BP but not usually to the level seen in this patient.

The patient says she smokes one pack of cigarettes daily and drinks 'about a pack of beer' every day. The nurse notes what nonmodifiable risk factor for hypertension?
Correct Answer: C
Rationale: Unlike cholesterol levels, alcohol intake and adherence to treatment, family history is not modifiable.
