A nurse is caring for a client who is taking triamterene. For which of the following laboratory values should the nurse withhold the medication?
BUN 16 mg/dL
Potassium 5.3 mEq/L
Sodium 142 mEq/L
Albumin 4 g/Dl
The Correct Answer is B
Choice A rationale:
BUN (blood urea nitrogen) measures kidney function and hydration status but is not a specific indicator for withholding triamterene.
Choice B rationale:
Triamterene is a potassium-sparing diuretic. With a potassium level of 5.3 mEq/L, which is elevated, the nurse should withhold the medication to prevent further potassium retention.
Choice C rationale:
Sodium level of 142 mEq/L is within the normal range and does not indicate a need to withhold triamterene.
Choice D rationale:
Albumin level of 4 g/dL is within the normal range and does not directly impact the decision to withhold triamterene.

Correct Answer is B
Explanation
Choice A rationale:
Alopecia (hair loss) is not a common adverse effect of paroxetine.
Choice B rationale:
Drowsiness is a potential adverse effect of paroxetine, an antidepressant medication that can cause central nervous system effects.
Choice C rationale:
Tinnitus (ringing in the ears) is not commonly associated with paroxetine use.
Choice D rationale:
Peripheral edema is not a common adverse effect of paroxetine.
Correct Answer is D
Explanation
Choice A rationale:
Hypomagnesemia involves a deficiency of magnesium, and it's not directly related to starting an exercise program while taking lithium.
Choice B rationale:
Hypokalemia involves low levels of potassium, which might not be directly influenced by the client's exercise program.
Choice C rationale:
Hypocalcemia involves low levels of calcium, and exercise is not a primary factor affecting calcium balance.
Choice D rationale:
Hyponatremia involves low levels of sodium in the blood. Starting a new exercise program while taking lithium can lead to increased sweating, potentially causing a loss of sodium. Lithium itself can also impact sodium levels. Monitoring for hyponatremia is important due to its potential impact on lithium toxicity.
