In caring for a client with encephalitis due to West Nile virus, which action should the nurse prioritize?

In a patient with encephalitis due to West Nile virus, monitoring vital signs every two hours is essential as it provides critical information about the patient's neurological status and overall stability. Vital signs, particularly temperature and blood pressure, can indicate changes in the patient's condition, such as the development of complications or the effectiveness of treatments. In encephalitis cases, where the risk for increased intracranial pressure and neurological deficits is significant, regular monitoring allows the healthcare team to detect any deterioration early and intervene promptly.

The other actions, while also important, may not take precedence in this acute setting. Administering medications as prescribed is necessary, but it is a routine task that can be managed alongside close monitoring of vital signs. Encouraging frequent fluid intake helps maintain hydration and can be crucial; however, it is secondary to the immediate need for assessing vital signs in a patient with potential neurological compromise. Documenting daily weights, while useful for tracking the patient's overall health and response to treatment, does not provide the immediate insight needed to manage acute changes in a patient experiencing encephalitis. Prioritizing vital sign monitoring ensures that the nurse can respond swiftly to any acute changes in the patient's condition.
