A patient is diagnosed with hypokalemia. After reviewing the patient's current medications, which drug should the nurse consider that might have contributed to the patient's health problem?

Narcotic.

Thiazide diuretic.

Corticosteroid.

Muscle relaxer.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Narcotics are not known to directly cause hypokalemia. Their main effects are related to pain relief and central nervous system depression.

Choice B rationale:

Thiazide diuretics can cause potassium loss in the urine, leading to hypokalemia. These diuretics work by inhibiting sodium reabsorption in the distal convoluted tubule, which can lead to potassium excretion as well.

Choice C rationale:

Corticosteroids can cause sodium and water retention but are not typically associated with significant potassium abnormalities.

Choice D rationale:

Muscle relaxers are not known to cause hypokalemia. They primarily act on the neuromuscular junction and do not directly impact potassium levels.

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

Explanation

The correct answer is choice A, C, and D.

Choice A rationale:

Lethargy is a common symptom of metabolic alkalosis due to the body’s attempt to compensate for the altered pH balance, leading to decreased energy levels and fatigue.

Choice B rationale:

Kussmaul’s respirations are typically associated with metabolic acidosis, not alkalosis. These deep, labored breaths are the body’s way of trying to expel excess carbon dioxide to correct acidosis.

Choice C rationale:

Circumoral paresthesia, or tingling around the mouth, is a symptom of metabolic alkalosis. This occurs due to changes in calcium ion concentration affecting nerve function.

Choice D rationale:

Bicarbonate excess is a direct cause of metabolic alkalosis. Elevated bicarbonate levels in the blood lead to an increased pH, resulting in alkalosis.

Choice E rationale:

Flushing is not a typical symptom of metabolic alkalosis. It is more commonly associated with conditions that cause vasodilation or increased blood flow to the skin.

A. Increased urine ketones. B. Decreased Hgb. C. Decreased urine specific gravity. D. Increased BUN.

Correct Answer is D

Explanation

Choice A rationale:

Increased urine ketones are not indicative of fluid volume deficit. Instead, they may suggest diabetic ketoacidosis or starvation ketosis.

Choice B rationale:

Decreased Hgb (hemoglobin) is not specific to fluid volume deficit and can be seen in various conditions such as anemia or bleeding.

Choice C rationale:

Decreased urine specific gravity is not consistent with fluid volume deficit, as it usually results in concentrated urine with increased specific gravity.

Choice D rationale:

An increased blood urea nitrogen (BUN) level is expected in fluid volume deficit due to reduced kidney perfusion and function. BUN is a marker of kidney function and is elevated when fluid volume is low.
