A nurse is evaluating a client who has hypertension and is taking lisinopril, an angiotensin II receptor blocker (ARB). Which of the following outcomes indicates that the medication is effective?

The client has no edema in the lower extremities.

The client has a urine output of 30 mL/hr.

The client has a blood pressure of 120/78 mm Hg.

The client has a serum creatinine level of 1.2 mg/dL.

Answer and Explanation

The Correct Answer is C

The client has a blood pressure of 120/78 mm Hg. This indicates that the medication is effective because it lowers the blood pressure below the hypertensive levels. In adults 60 years of age or older, this is typically defined as a systolic pressure below 150 mm Hg and a diastolic pressure below 90 mm Hg.

Choice A is wrong because the client has no edema in the lower extremities. This is not a specific outcome of lisinopril, an angiotensin II receptor blocker (ARB). Edema can be caused by many factors, such as heart failure, kidney disease, or venous insufficiency. Lisinopril does not directly affect fluid retention or edema.

Choice B is wrong because the client has a urine output of 30 mL/hr. This is a low urine output that may indicate dehydration, kidney impairment, or urinary obstruction. Lisinopril is expected to increase urine output by reducing the blood pressure and improving the renal blood flow.

Choice D is wrong because the client has a serum creatinine level of 1.2 mg/dL. This is a high serum creatinine level that may indicate kidney damage or reduced kidney function. Lisinopril is expected to lower the serum creatinine level by preventing the progression of kidney disease and protecting the kidney from further injury.

Normal ranges of urine output, blood pressure, and serum creatinine are:

• Urine output: 800 to 2000 mL/day or 40 to 80 mL/hr

• Blood pressure: less than 120/80 mm Hg for adults

• Serum creatinine: 0.6 to 1.2 mg/dL for males and 0.5 to 1.1 mg/dL for females

Correct Answer is ["A","C"]

Explanation

Losartan (Cozaar) is an angiotensin II receptor blocker (ARB) that is used to treat heart failure by lowering blood pressure and reducing fluid retention.

Patients taking losartan should:

• Weigh themselves every morning and report any changes.

This helps to monitor fluid status and detect signs of worsening heart failure.Weight gain of more than 2 kg (4.4 lb) in a week or 1 kg (2.2 lb) in a day should be reported to the health care provider.

• Call their doctor if they have a sore throat or fever.This could indicate an infection or a rare but serious side effect of losartan called angioedema, which causes swelling of the face, lips, tongue, or throat.

The other choices are wrong because:

• Losartan does not need to be taken with food to prevent stomach upset.It can be taken with or without food.

• Losartan does not increase the sensitivity to sunlight.However, some other medications for heart failure, such as diuretics, may do so.

• Drinking plenty of fluids to stay hydrated is not recommended for patients with heart failure, as it may worsen fluid retention and overload the heart.Patients should follow their prescribed fluid restriction and limit their sodium intake.

A. Serum potassium level B. Serum sodium level C. Serum magnesium level D. Serum calcium level.

Correct Answer is A

Explanation

The nurse should monitor the serum potassium level to determine the therapeutic effectiveness of digoxin (Lanoxin), a cardiac glycoside that improves the contractility and pumping ability of the heart. Digoxin has a narrow therapeutic range and can cause toxicity if the serum level is too high or if the patient has hypokalemia (low potassium).Hypokalemia can result from diuretic therapy, which is often prescribed for heart failure patients to reduce fluid overload.

Therefore, the nurse should monitor the serum potassium level and report any abnormal values to the provider.The normal potassium level is 3.5 to 5.0 mEq/L.

Choice B) Serum sodium level is wrong because sodium level is not directly affected by digoxin therapy.

Sodium level may be altered in heart failure patients due to fluid retention or diuretic use, but it does not indicate the effectiveness of digoxin.

Choice C) Serum magnesium level is wrong because magnesium level is not directly affected by digoxin therapy.

Magnesium level may be altered in heart failure patients due to diuretic use or renal impairment, but it does not indicate the effectiveness of digoxin.

Choice D) Serum calcium level is wrong because calcium level is not directly affected by digoxin therapy.

Calcium level may be altered in heart failure patients due to renal impairment or vitamin D deficiency, but it does not indicate the effectiveness of digoxin.
