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 D
Explanation
The correct answer is choice D: Reduction of T-wave amplitude.
Choice A rationale:
The amplitude of the QRS complex is not directly affected by changes in serum potassium levels. It represents ventricular depolarization, and its restoration would not be an expected outcome of polystyrene sulfonate treatment
Choice B rationale:
Shortening of the P-wave duration is not an expected change with polystyrene sulfonate treatment. The P-wave represents atrial depolarization, which is not significantly impacted by the administration of this medication
Choice C rationale:
Widening of the QRS complex is associated with high serum potassium levels. The goal of polystyrene sulfonate treatment is to lower potassium levels and, thus, return the QRS complex to its normal width
Choice D rationale:
Polystyrene sulfonate aims to reduce serum potassium levels. When effective, this should result in a reduction of T-wave amplitude, which is a common ECG change seen with hyperkalemia
In conclusion, choice D is the correct answer, as a reduction in T-wave amplitude would be the expected change on the client's ECG if polystyrene sulfonate effectively lowers their serum potassium level.
Correct Answer is A
Explanation
Choice A rationale:
The arterial blood gas results show a low pH (acidosis) and an elevated Paco2 (partial pressure of carbon dioxide), which indicates respiratory acidosis. This condition occurs when there is inadequate removal of carbon dioxide through ventilation, leading to an accumulation of carbonic acid in the blood and a decrease in pH.
Choice B rationale:
Metabolic acidosis would present with a low pH and a low bicarbonate (HCO3-) level, not an elevated Paco2.
Choice C rationale:
Metabolic alkalosis would present with a high pH and an elevated bicarbonate (HCO3-) level, not an elevated Paco2.
Choice D rationale:
Respiratory alkalosis would present with a high pH and a decreased Paco2, not an elevated Paco2 as seen in this case.
