A nurse is preparing to administer mannitol IV to a client.
The nurse should monitor the client for which of the following manifestations as an expected outcome of this medication?

Decreased thyroxine levels.

Correction of atrial flutter.

Reduced intracranial pressure.

Increased hemoglobin levels.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Mannitol is an osmotic diuretic that doesn't directly impact thyroid function. Its primary role is to increase osmotic pressure in the kidneys, promoting diuresis to reduce fluid volume, particularly in cases of cerebral edema.

Choice B rationale

Mannitol does not have antiarrhythmic properties; its effects are primarily on osmotic diuresis, which reduces intracranial pressure. Atrial flutter is managed with medications such as beta-blockers or calcium channel blockers that directly affect cardiac rhythm.

Choice C rationale

Mannitol's osmotic diuretic effect increases renal excretion of water, reducing intracranial pressure by drawing fluid out of the brain tissue into the bloodstream. This mechanism alleviates symptoms of increased intracranial pressure, such as headache and nausea.

Choice D rationale

Mannitol administration doesn't influence hemoglobin levels directly. It affects fluid balance by increasing urine output, not by altering erythropoiesis or blood composition. Hemoglobin levels are more affected by factors like anemia or hydration status.

Correct Answer is ["A","B","E"]

Explanation

Choice A rationale

Prednisone, a corticosteroid, causes potassium loss through increased renal excretion, leading to hypokalemia. Normal serum potassium: 3.5-5.0 mEq/L.

Choice B rationale

Torsemide, a loop diuretic, increases renal potassium loss, causing hypokalemia. Normal serum potassium: 3.5-5.0 mEq/L.

Choice C rationale

Polystyrene sulfonate treats hyperkalemia by binding potassium in the gut, reducing serum potassium levels. Normal serum potassium: 3.5-5.0 mEq/L.

Choice D rationale

Spironolactone is a potassium-sparing diuretic, reducing the risk of hypokalemia. Normal serum potassium: 3.5-5.0 mEq/L.

Choice E rationale

Hydrochlorothiazide, a thiazide diuretic, increases renal potassium loss, leading to hypokalemia. Normal serum potassium: 3.5-5.0 mEq/L.

A. Glucose. B. Prothrombin time. C. Serum creatinine. D. Cardiac enzymes. E. WBC count.

Correct Answer is C

Explanation

Choice A rationale

Glucose monitoring is essential for patients with diabetes or at risk of hypoglycemia, but it is not directly relevant to gentamicin therapy.

Choice B rationale

Prothrombin time measures clotting ability, which is more relevant to anticoagulant therapy, not gentamicin, which is an antibiotic.

Choice C rationale

Serum creatinine is a key indicator of kidney function, and gentamicin can cause nephrotoxicity, making this lab value critical to monitor. Normal range: 0.6-1.2 mg/dL.

Choice D rationale

Cardiac enzymes are used to diagnose myocardial infarction and other cardiac conditions, not typically monitored with gentamicin use.

Choice E rationale

WBC count is important in assessing infection or immune response but does not indicate adverse effects specific to gentamicin.
