A nurse is caring for a client who is taking azathioprine to treat rheumatoid arthritis. Which of the following laboratory values indicates an adverse effect of this medication?

Choice A Reason:
"I should avoid drinking grapefruit juice." This statement is actually accurate. Grapefruit juice can interfere with the metabolism of certain statin medications, including lovastatin, leading to increased levels of the drug in the body. Advising against grapefruit juice consumption is a recommended precaution when taking lovastatin, so this statement shows the client's understanding of this interaction.
Choice B Reason:
"I am trying to decrease my dietary fat intake." This statement reflects a positive lifestyle change. Lowering dietary fat intake is often recommended for individuals on statin medications to help manage cholesterol levels. This statement demonstrates the client's commitment to making healthy dietary adjustments, which aligns with the treatment plan.
Choice B Reason:
"I was just diagnosed with hepatitis B. "Hepatitis B can affect liver function, and statin medications like lovastatin can potentially impact liver enzymes. Therefore, in someone with a history of hepatitis B, it's crucial to assess liver function before starting a statin and to monitor the liver during treatment. This statement raises concerns about potential liver complications or interactions that require further evaluation before initiating lovastatin.
Choice D Reason:
"I take metformin for my diabetes." Metformin, a medication for diabetes, does not directly interact with lovastatin. While it's relevant to know the client's other medications, this statement doesn't indicate a need for immediate further assessment regarding the use of lovastatin.

Choice A Reason:
Contact the provider to clarify the prescription is not appropriate. Contacting the provider might not be necessary in this case. The prescription specifies "NOW," indicating an urgent administration, which is a clear directive to administer the medication promptly without further clarification.
Choice B Reason:
Administer the medication within 90 minutes is appropriate. "NOW" typically implies an urgent need for administration, and within a hospital setting, "NOW" often indicates a timeframe of around 90 minutes for prompt administration of the medication.
Choice C Reason:
Notify the pharmacy to send the medication immediately is inappropriate. With the prescription stating "NOW," the need for immediate administration usually requires using the hospital's available stock of the medication rather than waiting for delivery from the pharmacy. This action might cause a delay in administration.
Choice D Reason:
Inform the client there is a prescription available if needed is inappropriate. This option is not suitable in this scenario. "NOW" in the prescription implies the immediate need for administration, so informing the client about the availability of the prescription doesn't align with the urgency implied by the directive "NOW."
