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.
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
The correct answer is B. 600 milliliters.
Choice A rationale:
A 24-hour urine output of 1000 milliliters is within the normal range for an adult, indicating adequate kidney function and hydration.
Choice B rationale:
A 24-hour urine output of 600 milliliters is below the normal range (typically 800-2000 milliliters), which may indicate oliguria (reduced urine output) and could be a sign of renal impairment or dehydration. This warrants notifying the healthcare provider.
Choice C rationale:
A 24-hour urine output of 1200 milliliters is also within the normal range, suggesting normal kidney function and hydration status.
Choice D rationale:
A 24-hour urine output of 750 milliliters is slightly below the normal range but may not be immediately concerning unless accompanied by other symptoms. However, it is still important to monitor and possibly notify the healthcare provider if it persists.
Correct Answer is C
Explanation
PacO2 50 mm Hg. Choice A rationale:
Potassium levels are not directly related to respiratory acidosis. Potassium levels may be affected in certain conditions, but they are not specific indicators of respiratory acidosis.
Choice B rationale:
HCO3- (bicarbonate) levels may be elevated in metabolic alkalosis, not respiratory acidosis. In respiratory acidosis, the primary abnormality is an increased PacO2, not HCO3-.
Choice C rationale:
The partial pressure of carbon dioxide (PacO2) is a key parameter in diagnosing respiratory acidosis. In this case, a PacO2 of 50 mm Hg suggests hypoventilation and an excess of carbon dioxide in the blood, contributing to acidosis.
Choice D rationale:
The pH level given (pH 7.45) is within the normal range, which contradicts the diagnosis of respiratory acidosis. In respiratory acidosis, the pH would be expected to be below the normal range of 7.35-7.45 due to increased carbon dioxide levels.
