A nurse is assessing a 28-year-old client with HIV who has been admitted with pneumonia. Which of the following observations should the nurse prioritize?

Choice A rationale:
While taking colchicine with food can help minimize gastrointestinal side effects like nausea, it's not the most crucial instruction for this medication. The primary concern with colchicine is its potential for muscle toxicity.

Choice B rationale:
Colchicine can cause muscle pain, tenderness, or weakness, which can be a sign of a serious condition called rhabdomyolysis. Rhabdomyolysis involves the breakdown of muscle tissue, potentially leading to kidney damage and other complications.
It's crucial for patients to monitor for muscle pain and report it to their healthcare provider promptly if it occurs. Early detection and intervention can help prevent serious complications.

Choice C rationale:
Increased bruising is not a common side effect of colchicine. It's more frequently associated with medications that affect blood clotting, such as warfarin or aspirin.

Choice D rationale:
Grapefruit juice can interact with many medications, including colchicine. It can increase the concentration of colchicine in the bloodstream, potentially leading to toxicity.
It's crucial for patients taking colchicine to avoid grapefruit juice and other grapefruit products.

Rationale for Choice A:
Phenytoin is an anticonvulsant medication used to control seizures. It is typically a long-term medication, and abruptly stopping it can lead to breakthrough seizures or worsen existing seizures.
This statement indicates that the client may not understand the importance of taking phenytoin consistently and the potential consequences of discontinuing it without consulting their doctor.

Rationale for Choice B:
Making an appointment with a dentist is important for all individuals, including those with seizure disorders. There is no specific concern related to phenytoin and dental care that would necessitate further teaching in this context.

Rationale for Choice C:
It is important for clients to understand that switching brands of phenytoin might affect its effectiveness due to slight variations in formulation. However, simply stating awareness of this fact does not necessarily indicate a need for further teaching, as the nurse can assess the client's understanding through further questioning.

Rationale for Choice D:
Notifying a doctor before taking any new medications is crucial for individuals with seizures, as some medications can interact with phenytoin and increase the risk of seizures. This statement demonstrates the client's understanding of an important safety precaution.
Therefore, Choice A is the only statement that suggests a potential lack of understanding about the long-term nature of phenytoin treatment and the dangers of discontinuing it without medical supervision. This highlights the need for further education to ensure the client's safety and adherence to the prescribed medication regimen.
