Choice C rationale
Hypokalemia can occur, particularly in patients with certain medical conditions or those taking diuretics, but it is not the most common risk.
Choice D rationale

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

Explanation

Choice A rationale
Prednisone, a corticosteroid, can cause hypokalemia by increasing renal potassium excretion.
Choice B rationale
Torsemide, a loop diuretic, can lead to hypokalemia by promoting potassium loss through urine.
Choice C rationale
Polystyrene sulfonate is used to treat hyperkalemia, but it can cause hypokalemia as it removes potassium from the body.
Choice E rationale
Hydrochlorothiazide, a thiazide diuretic, can cause hypokalemia by increasing potassium excretion in the urine.

A. Decreased thyroxine levels. B. Correction of atrial flutter. C. Reduced intracranial pressure. D. Increased hemoglobin levels.

Correct Answer is C

Explanation

Choice A rationale
Mannitol is an osmotic diuretic used primarily to reduce intracranial pressure (ICP) and treat cerebral edema. It does not affect thyroxine levels, which are related to thyroid function. Thyroxine levels are regulated by the thyroid gland and are not influenced by mannitol administration.
Choice B rationale
Mannitol is not used to correct atrial flutter. Atrial flutter is a type of arrhythmia that requires specific antiarrhythmic medications or procedures such as cardioversion. Mannitol’s primary action is to increase osmotic pressure in the kidneys, leading to diuresis and reduction of fluid in tissues, including the brain.
Choice C rationale
Mannitol is effective in reducing intracranial pressure by creating an osmotic gradient that draws fluid from the brain tissue into the bloodstream, which is then excreted by the kidneys. This reduction in intracranial pressure is a desired therapeutic outcome when treating conditions like cerebral edema.
Choice D rationale
Mannitol does not increase hemoglobin levels. Hemoglobin levels are influenced by factors such as red blood cell production and destruction, iron levels, and overall health status. Mannitol’s mechanism of action is related to fluid balance and diuresis, not hematopoiesis.
