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 B

Explanation

Choice A rationale:

A phosphorus level of 4.5 mEq/L falls within the normal range, which is typically between 2.5 to 4.5 mEq/L. Although it's essential to monitor phosphorus levels, it is not the priority finding in this scenario.

Choice B rationale:

A potassium level of 2.9 mEq/L is the priority finding. The normal range for potassium is typically between 3.5 to 5.0 mEq/L. A potassium level of 2.9 mEq/L indicates severe hypokalemia, which can lead to life-threatening cardiac arrhythmias and muscle weakness. Immediate intervention is necessary to address the potassium imbalance.

Choice C rationale:

A calcium level of 8.2 mg/dL falls within the normal range (typically 8.5 to 10.2 mg/dL). While calcium levels are essential to monitor, they do not take precedence over the critically low potassium level in this situation.

Choice D rationale:

A sodium level of 145 mEq/L falls within the normal range, which is usually around 135 to 145 mEq/L. Although monitoring sodium levels is important, it is not the priority finding when compared to the critically low potassium level.

A. Encourage the patient to breathe in and out slowly into a paper bag. B. Immediately administer oxygen via a mask and monitor oxygen saturation. C. Anticipate the administration of intravenous sodium bicarbonate. D. Prepare to start an intravenous fluid bolus using isotonic fluids.

Correct Answer is A

Explanation

The correct answer is choice A: Encourage the patient to breathe in and out slowly into a paper bag.

Choice A rationale:The patient’s arterial blood gas (ABG) results indicate respiratory alkalosis, as evidenced by the elevated pH (7.48) and decreased PaCO2 (25 mm Hg). Respiratory alkalosis often results from hyperventilation, which can occur due to anxiety. Breathing into a paper bag helps to increase CO2 levels in the blood, thereby correcting the alkalosis.

Choice B rationale:Administering oxygen is not appropriate in this scenario because the patient’s PaO2 is already elevated (110 mm Hg), indicating that oxygenation is not the issue. Providing additional oxygen would not address the underlying problem of hyperventilation and respiratory alkalosis.

Choice C rationale:Intravenous sodium bicarbonate is used to treat metabolic acidosis, not respiratory alkalosis. In this case, the patient’s HCO3 is within the normal range (24 mEq/L), indicating that there is no metabolic acidosis present.

Choice D rationale:Starting an intravenous fluid bolus with isotonic fluids is not indicated for correcting respiratory alkalosis. This intervention is more appropriate for patients experiencing hypovolemia or dehydration, which is not suggested by the patient’s ABG results.
