A nurse is caring for a client who has hypertension and is prescribed metoprolol, a beta blocker. The nurse should monitor the client for which of the following adverse effects?

Tachycardia

Hyperglycemia

Bronchospasm

Hyperkalemia.

Answer and Explanation

The Correct Answer is C

This is because metoprolol is a beta blocker, which can block the beta-2 receptors in the lungs and cause constriction of the airways. This can lead to breathing problems such as shortness of breath, cough, and wheezing. Bronchospasm is more likely to occur in people who have asthma or chronic obstructive pulmonary disease (COPD).

Choice A is wrong because tachycardia, or fast heart rate, is not an adverse effect of metoprolol. In fact, metoprolol can lower the heart rate by blocking the beta-1 receptors in the heart. A normal resting heart rate for adults ranges from 60 to 100 beats per minute (bpm). Metoprolol can cause bradycardia, or slow heart rate, which can be a serious side effect if it is too low.

Choice B is wrong because hyperglycemia, or high blood sugar, is not an adverse effect of metoprolol. Metoprolol does not affect the insulin secretion or glucose metabolism in the body. A normal blood sugar level for adults without diabetes is less than 140 mg/dL (7.8 mmol/L) two hours after eating. Metoprolol can cause hypoglycemia, or low blood sugar, in people who have diabetes and take insulin or other glucose-lowering medications. This is because metoprolol can mask the symptoms of hypoglycemia, such as palpitations and tremors.

Choice D is wrong because hyperkalemia, or high potassium, is not an adverse effect of metoprolol. Metoprolol does not affect the potassium balance in the body.

A normal blood potassium level for adults is 3.6 to 5.2 millimoles per liter (mmol/L)

Correct Answer is A

Explanation

The nurse should monitor the client’s serum potassium level closely because furosemide is a loop diuretic that can cause hypokalemia, which increases the risk of cardiac arrhythmias and digitalis toxicity. The nurse should also monitor the client’s fluid status, blood pressure, and renal function.

Choice B is wrong because Serum calcium is wrong because furosemide does not affect calcium levels significantly. Calcium levels are more likely to be affected by thiazide diuretics, which can cause hypercalcemia.

Choice C is wrong because Serum albumin is wrong because furosemide does not affect albumin levels significantly. Albumin levels are more likely to be affected by liver disease, malnutrition, or nephrotic syndrome.

Choice D is wrong because Serum glucose is wrong because furosemide does not affect glucose levels significantly. Glucose levels are more likely to be affected by diabetes mellitus, corticosteroids, or stress.

Normal ranges for the laboratory values are:

• Serum potassium: 3.5-5.0 mEq/L

• Serum calcium: 8.5-10.5 mg/dL

• Serum albumin: 3.5-5.0 g/dL

• Serum glucose: 70-110 mg/dL

A. Administer diltiazem as ordered by physician B. Instruct patient to change positions slowly C. Notify physician immediately D. Hold diltiazem and notify physician if symptoms persist. E. Hold diltiazem and notify physician if symptoms persist.

Correct Answer is B

Explanation

This is because diltiazem (Cardizem) is a calcium channel blocker that lowers blood pressure and can cause orthostatic hypotension, which is a sudden drop in blood pressure when standing up from a sitting or lying position. This can lead to dizziness and lightheadedness, which can increase the risk of falls and injuries. Changing positions slowly can help prevent or reduce these symptoms by allowing the body to adjust to the change in blood pressure.

Choice A) Administer diltiazem as ordered by physician is wrong because it does not address the patient’s complaint of dizziness and lightheadedness, which are side effects of the medication.

The nurse should monitor the patient’s blood pressure and heart rate before and after administering diltiazem, and report any abnormal findings to the physician.

Choice C) Notify physician immediately is wrong because it is not necessary to notify the physician immediately for a common and mild side effect of diltiazem, unless the patient has other signs of severe hypotension, such as fainting, chest pain, or confusion.

The nurse should educate the patient about the possible side effects of diltiazem and how to prevent or manage them.

Choice D) Hold diltiazem and notify physician if symptoms persist is wrong because it is not appropriate to hold a prescribed medication without a valid reason or an order from the physician.

Holding diltiazem could cause the patient’s blood pressure to rise and increase the risk of complications from atrial fibrillation, such as stroke or heart failure.

The nurse should administer diltiazem as ordered and monitor the patient’s response.
