- A. dizziness
- B. tachycardia

The nurse is caring for a client who received a prescription for amlodipine for hypertension and was advised to lose weight. Which of the following statements by the client would require follow-up?
- A. I have enrolled myself at a gym and I am receiving dietary counseling from a nutritionist.
- B. I should drink grapefruit juice while taking the amlodipine.
- C. What is the best way for me to follow my treatment regimen with diet and exercise?
- D. Sometimes I feel dizzy after taking the amlodipine pills.
Correct Answer: B,D
Rationale: Grapefruit juice can increase amlodipine levels, leading to toxicity, and dizziness may indicate hypotension, both requiring follow-up. Gym enrollment and questions about regimen compliance are appropriate.
The nurse is counseling a client with congestive heart failure (CHF) about newly prescribed bumetanide. The nurse determines that the teaching has been effective when the client plans to
- A. increase their daily intake of protein.
- B. record their daily urinary output.
- C. weigh themselves daily.
- D. take their blood pressure and pulse daily.
Correct Answer: C
Rationale: Bumetanide, a loop diuretic, requires daily weight monitoring to assess fluid status in CHF. Protein intake, urinary output records, or vital signs monitoring are less critical.
The nurse is preparing an educational in-service about valsartan. Which of the following information should the nurse include?
- A. Valsartan blocks the conversion of angiotensin I to angiotensin II.
- B. Valsartan antagonizes angiotensin II receptors.
- C. Valsartan stimulates alpha-2 adrenoceptors in the brainstem.
- D. Valsartan blocks response to beta1- and beta2-adrenergic stimulation.
Correct Answer: B
Rationale: Valsartan, an ARB, antagonizes angiotensin II receptors, reducing blood pressure. It does not block angiotensin conversion, stimulate alpha-2 receptors, or block beta-adrenergic responses.
The emergency department (ED) nurse is caring for a client with a hypertensive emergency. The nurse should obtain a prescription for intravenous
- A. dobutamine
- B. digoxin
- C. nicardipine
- D. amiodarone
Correct Answer: C
Rationale: Nicardipine, an IV calcium channel blocker, is used to rapidly lower blood pressure in a hypertensive emergency. Dobutamine (an inotrope), digoxin (a cardiac glycoside), and amiodarone (an antiarrhythmic) are not appropriate for this condition.
The nurse has taught a client who has been prescribed clonidine via a transdermal patch. Which of the following statements by the client would indicate a need for further teaching?
- A. I can wear this patch while I shower.
- B. I should keep this patch on for five days.
- C. This medication may make me drowsy.
- D. If I ever have to have a magnetic resonance imaging (MRI), I will need to remove the patch before the test.
Correct Answer: B
Rationale: Clonidine transdermal patches are typically changed every 7 days, not 5 days, so the statement about keeping the patch on for five days indicates a need for further teaching. The other statements are correct: clonidine patches are water-resistant, can cause drowsiness, and must be removed before an MRI due to potential metal content.
