A nurse is caring for a client who is taking naproxen following an exacerbation of rheumatoid arthritis. Which of the following statements by the client requires further discussion by the nurse?

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.

Choice A rationale:
Hydroxychloroquine can cause a rare but serious side effect called bone marrow suppression. This is a decrease in the production of blood cells in the bone marrow.
White blood cells (WBCs) are a key component of the immune system, and a decrease in WBCs can make a patient more susceptible to infections.
Therefore, it's crucial for nurses to monitor the patient's WBC count to detect any potential bone marrow suppression early and take necessary actions to prevent or manage infections.
Choice B rationale:
An increased blood cell count is not a typical side effect of hydroxychloroquine.
Some conditions, like polycythemia vera, can cause an increase in blood cell count, but they are not related to hydroxychloroquine use.

Choice C rationale:
While hydroxychloroquine can sometimes cause a decrease in platelet count, it's less common than bone marrow suppression affecting WBCs.
However, it's still essential for nurses to monitor platelet counts as well, as a significantly low platelet count can impair blood clotting and increase the risk of bleeding.
Choice D rationale:
Hydroxychloroquine does not typically affect red blood cell (RBC) counts.
Conditions that affect RBC counts, such as anemia, are not directly related to hydroxychloroquine use.
