The nurse is caring for a patient with chronic heart failure who has been prescribed digoxin (Lanoxin). The patient’s apical pulse rate is 58 beats/min. What should the nurse do next?

Administer the medication as ordered.

Hold the medication and notify the provider.

Check the patient’s serum digoxin level.

Give an additional dose of digoxin.

Answer and Explanation

The Correct Answer is B

Digoxin (Lanoxin) is a cardiac glycoside that is used to improve the contractility of the heart and slow down the heart rate in patients with chronic heart failure. However, digoxin has a narrow therapeutic range and can cause toxicity if the dose is too high or if the patient has low potassium levels. A normal serum digoxin level is 0.5 to 2 ng/mL and a normal serum potassium level is 3.5 to 5 mEq/L. A low heart rate (less than 60 beats/min) is a sign of digoxin toxicity and the nurse should withhold the medication and report it to the provider. The nurse should also check the patient’s serum digoxin and potassium levels to determine if they are within normal limits.

Choice A is wrong because administering the medication as ordered could worsen the patient’s condition and increase the risk of digoxin toxicity.

Choice C is wrong because checking the patient’s serum digoxin level is not enough to prevent digoxin toxicity. The nurse should also check the patient’s serum potassium level and heart rate before giving digoxin.

Choice D is wrong because giving an additional dose of digoxin could cause a fatal overdose and lead to cardiac arrest. The nurse should never give more than the prescribed dose of digoxin without consulting the provider.

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

Explanation

Nifedipine is a calcium channel blocker that lowers blood pressure by relaxing the blood vessels and reducing the workload of the heart.

The following instructions should be included in the teaching:

• Avoid drinking alcohol while taking this medication.Alcohol can increase the risk of side effects such as dizziness, flushing, headache, and low blood pressure.

• Monitor your blood pressure and pulse regularly.This will help to evaluate the effectiveness of the medication and detect any abnormal changes.Normal blood pressure for adults is less than 130/80 mm Hg and normal pulse rate is 60 to 100 beats per minute.

• Report any swelling in your ankles or feet to your provider.This can be a sign of fluid retention or heart failure, which are possible complications of nifedipine.

• Do not stop taking this medication abruptly.This can cause a rebound increase in blood pressure and chest pain.The dose should be tapered gradually under the supervision of the provider.

Choice E is wrong because chewing or crushing the sustained-release tablet can cause too much of the drug to be released at once, which can lead to overdose or severe side effects.

The tablet should be swallowed whole with a glass of water.

A. Fresh fruits and vegetables B. Whole grains and cereals C. Lean meats and poultry D. Canned soups and sauces.

Correct Answer is D

Explanation

The nurse should advise the patient with heart failure to limit or avoid canned soups and sauces because they are high in sodium, which can cause fluid retention and worsen cardiac function.Sodium intake should be restricted to less than 2 g per day for patients with heart failure.

Choice A is wrong because fresh fruits and vegetables are good sources of potassium, magnesium, and fiber, which are beneficial for heart health.Potassium and magnesium help regulate fluid and electrolyte balance, and fiber helps lower cholesterol and blood pressure.

Choice B is wrong because whole grains and cereals are also rich in fiber, as well as complex carbohydrates, which provide energy and prevent rapid fluctuations in blood glucose levels.Whole grains and cereals may also contain phytochemicals that have antioxidant and anti-inflammatory effects.

Choice C is wrong because lean meats and poultry are low in saturated fat and cholesterol, which can contribute to atherosclerosis and coronary artery disease. Lean meats and poultry provide protein, which is essential for tissue repair and wound healing.Protein intake should be adequate but not excessive for patients with heart failure, as too much protein can increase the workload of the kidneys.
