A nurse is planning to administer mannitol to a client who has heart failure and pulmonary edema. Which of the following actions should the nurse take before giving the medication?

Check the urine output.

Check the blood pressure.

Check the blood glucose.

Check the oxygen saturation.

Answer and Explanation

The Correct Answer is A

Mannitol is an osmotic diuretic that increases urine output and decreases intracranial pressure and intraocular pressure. The nurse should check the urine output before giving the medication to ensure adequate renal function and prevent fluid overload and electrolyte imbalance. The normal urine output is 0.5 to 1 mL/kg/hr.

Choice B is wrong because checking the blood pressure is not specific to mannitol administration. Mannitol can cause hypotension or hypertension depending on the fluid status of the client, but this is not the priority action before giving the medication.

Choice C is wrong because checking the blood glucose is not relevant to mannitol administration. Mannitol does not affect blood glucose levels.

Choice D is wrong because checking the oxygen saturation is not related to mannitol administration. Mannitol does not affect oxygen saturation levels.

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. Angiotensin-converting enzyme (ACE) inhibitors B. Diuretics C. Adrenergic drugs D. Direct acting vasodilators.

Correct Answer is B

Explanation

Diuretics are drugs that increase the excretion of water and sodium by the kidneys, reducing blood volume and blood pressure.Diuretics lower blood pressure by dilating peripheral arterioles and decreasing blood volume by increasing the excretion of sodium and water.

Choice A is wrong because angiotensin-converting enzyme (ACE) inhibitors do not increase the excretion of water and sodium by the kidneys.ACE inhibitors block the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor and stimulator of aldosterone secretion.By reducing angiotensin II levels, ACE inhibitors lower blood pressure by dilating blood vessels and decreasing sodium and water retention.

Choice C is wrong because adrenergic drugs do not increase the excretion of water and sodium by the kidneys. Adrenergic drugs act on the sympathetic nervous system, which regulates heart rate, blood pressure, and other functions. Depending on the type and location of adrenergic receptors, adrenergic drugs can have different effects on blood pressure. Some adrenergic drugs can increase blood pressure by stimulating alpha receptors, which cause vasoconstriction.Other adrenergic drugs can decrease blood pressure by stimulating beta receptors, which cause vasodilation and decreased cardiac output.

Choice D is wrong because direct acting vasodilators do not increase the excretion of water and sodium by the kidneys. Direct acting vasodilators are drugs that relax the smooth muscle of blood vessels, causing them to widen and lower blood pressure.Direct acting vasodilators do not affect the renin-angiotensin-aldosterone system or the sympathetic nervous system, which regulate sodium and water balance.
