A nurse is assessing a client who takes salmeterol to treat moderate asthma. Which of the following findings should indicate to the nurse that the medication has been effective?

Choice A rationale:
Papilledema refers to swelling of the optic disc in the eye, which can occur due to increased intracranial pressure. While it may be present in cases of basilar skull fracture, it is not a reliable finding for determining the discharge of cerebrospinal fluid (CSF).
Choice B rationale:
The halo sign is a reliable finding for determining that the nasal discharge is cerebrospinal fluid. The halo sign is characterized by a ring of blood surrounded by a clear or yellowish fluid (CSF) on a dressing or tissue. This occurs because blood from the fracture mixes with the clear CSF, creating a distinct appearance.
Choice C rationale:
Racoon's eyes, also known as periorbital ecchymosis, is a term used to describe bruising around the eyes. While it can be seen in basilar skull fractures, it is not specific to cerebrospinal fluid leakage and, therefore, not reliable for identifying the nasal discharge as CSF.
Choice D rationale:
Elevated white blood cells (WBCs) in the nasal discharge can indicate infection, inflammation, or an immune response. However, it does not provide direct evidence that the discharge is cerebrospinal fluid, so this is not a reliable finding for determining the nature of the nasal discharge in this context.

Choice A rationale:
Notifying the surgeon of the temperature elevation is important, but it is not the nurse's priority. A temperature elevation after abdominal surgery could be a sign of infection, but the immediate action should be to assess the surgical incision for any signs of infection.
Choice B rationale:
Encouraging the client to drink more fluids is a good practice to maintain hydration and promote recovery after surgery. However, it is not the nurse's priority in this situation. The elevated temperature and potential infection take precedence over increasing fluid intake.
Choice C rationale:
This is the correct answer because the nurse's priority is to assess the surgical incision for signs of infection. An elevated temperature is a significant finding after surgery, and it may indicate a surgical site infection, which requires prompt assessment and intervention.
Choice D rationale:
Monitoring vital signs every 4 hours is an essential nursing intervention after surgery, but it is not the priority when the client has an elevated temperature and a recent surgical incision.
The nurse must first assess for signs of infection before proceeding with routine vital sign monitoring.
