A client takes atorvastatin (Lipitor), with laboratory results showing a blood urea nitrogen (BUN) of 33 mg/dL and creatinine of 2.8 mg/dL. What action by the nurse is best?
Correct Answer: A
Rationale: The correct answer is A: Ask if the client eats grapefruit. Atorvastatin can interact with grapefruit juice, leading to increased drug levels and potential toxicity. The elevated BUN and creatinine levels suggest possible kidney impairment, which could be exacerbated by the drug interaction. Assessing for grapefruit consumption allows the nurse to address this potential risk factor.
B: Assessing for dehydration would not directly address the potential drug interaction with grapefruit.
C: Hospital admission is not necessary based solely on the information provided; this would be an extreme action without further assessment.
D: Obtaining a random urinalysis would not provide relevant information related to the potential drug interaction with grapefruit.
