MULTIPLE CHOICE

1. An African-American patient is taking captopril (Capoten) 25 mg twice daily. When performing a physical examination, the primary care nurse practitioner (NP) learns that the patient continues to have blood pressure readings of 135/90 mm Hg. The NP should:

ANS:  B

Some African-American patients do not appear to respond as well as whites in terms of blood pressure reduction. The addition of a low-dose thiazide diuretic often allows for efficacy in blood pressure lowering that is comparable with that seen in white patients. Increasing the captopril dose is not indicated. Losartan is an angiotensin receptor blocker (ARB) and is not indicated in this case.

2. A patient with a previous history of myocardial infarction (MI) who takes nitroglycerin for angina develops hypertension. The primary care NP is considering ordering an ACE inhibitor. Preliminary laboratory tests reveal decreased renal function. The NP should:

ANS:  D

ACE inhibitors are contraindicated in patients with bilateral renal stenosis. Because this patient has decreased renal function, perfusion studies are indicated. If the patient does not have bilateral renal stenosis, a low-dose ACE inhibitor may be used. An ARB is indicated if perfusion studies show bilateral renal stenosis. A thiazide diuretic is not indicated.

3. A patient who has type 2 diabetes is seen by a primary care NP for a physical examination. The NP notes a blood pressure of 140/95 mm Hg on three occasions. A urinalysis reveals macroalbuminuria. The patient’s serum creatinine is 1.9 mg/dL. Adhering to evidence-based practice, the NP should prescribe:

ANS:  A

In patients with type 2 diabetes, hypertension, macroalbuminuria, and renal insufficiency (serum creatinine >1.5 mg/dL), ARBs have been shown to delay the progression of nephropathy. Losartan is an ARB. The other medications are ACE inhibitors.
