Which drug blocks the binding of angiotensin II to its receptors on blood vessels and adrenal glands, preventing its vasoconstrictive and aldosterone-stimulating effects?

Beta blockers

Calcium channel blockers

Angiotensin II receptor blockers (ARBs)

Direct acting vasodilators.

Answer and Explanation

The Correct Answer is C

Angiotensin II receptor blockers (ARBs) block the binding of angiotensin II to its receptors on blood vessels and adrenal glands, preventing its vasoconstrictive and aldosterone-stimulating effects

Choice A is wrong because beta blockers do not block angiotensin II receptors, but rather beta-adrenergic receptors, which are involved in the sympathetic nervous system. Beta blockers reduce heart rate and blood pressure by inhibiting the effects of adrenaline and noradrenaline

Choice B is wrong because calcium channel blockers do not block angiotensin II receptors, but rather calcium channels, which are involved in the contraction of smooth muscle cells. Calcium channel blockers relax blood vessels and lower blood pressure by reducing the influx of calcium into the cells

Choice D is wrong because direct acting vasodilators do not block angiotensin II receptors, but rather act directly on the smooth muscle cells of blood vessels, causing them to relax and dilate. Direct acting vasodilators lower blood pressure by decreasing peripheral resistance

Correct Answer is A

Explanation

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.

A. Serum potassium B. Serum calcium C. Serum albumin D. Serum glucose.

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
