Final answer:
A nurse should withhold clozapine medication if a client has a decreased white blood cell count, indicating agranulocytosis, a serious side effect. The listed side effects (weight gain, elevated blood pressure, dry mouth) do not usually warrant the immediate cessation of clozapine without other context.
Step-by-step explanation:
Important Considerations When Caring for a Client on Clozapine:
A nurse who is caring for a client on clozapine must monitor for several side effects associated with this medication. One of the most serious potential side effects is agranulocytosis, which is a dangerously low level of white blood cells (WBC). Therefore, if a client has a decreased, not increased, WBC count, it is imperative to withhold the medication and seek immediate medical attention.
While weight gain, elevated blood pressure, and dry mouth are indeed side effects of clozapine, these are not typically reasons to immediately stop the medication as agranulocytosis would be. Instead, these side effects may be managed with additional treatment or adjustments in the medication regimen. However, since the question specifically asks for which finding the nurse should withhold the medication, the correct answer is not provided in the options given; it would be a decreased WBC count. For the options listed, none directly indicate the need to withhold clozapine without additional context.
Patient B's symptoms of weight loss, profuse sweating, increased heart rate, and difficulty sleeping are not directly related to clozapine's side effects. However, they might indicate another condition like hyperthyroidism or an anxiety disorder, and it would be appropriate for the nurse to take these symptoms into account when providing overall caring for Patient B's health.
