Final answer:
The triage nurse should advise the client to come in for an assessment to confirm the diagnosis of the flu before prescribing zanamivir, since actual flu cases are relatively low among those reporting flu-like symptoms and proper diagnosis is necessary.
Step-by-step explanation:
When the triage nurse at a health clinic receives a call from a client stating they have been experiencing flu-like symptoms and requests a prescription for zanamivir, the nurse should proceed with caution. Considering the information that actual cases of the flu are relatively low among those reporting flu-like symptoms, a responsible response would be to advise the patient to come in for an evaluation before prescribing medication. Zanamivir, as a neuraminidase inhibitor, is effective in treating influenza but only if the patient indeed has the flu, and it is typically prescribed within the first 48 hours of symptom onset. Since symptoms could result from various illnesses, it is important for the nurse to encourage an in-person visit to confirm the diagnosis.
The correct answer from the given options would likely be D "Come in right away so we can start treating you." This would allow healthcare professionals to assess the condition properly and determine whether zanamivir or another form of treatment is appropriate.
