The nurse in the emergency department is caring for a client who has fallen 20 feet from a roof. While performing the primary assessment, what is the most important nursing intervention?

A. Intracranial pressure: Monitoring intracranial pressure is important in clients with a history of subdural hematoma, but immediate assessment of respiratory status takes precedence in the immediate postoperative period to ensure adequate oxygenation and ventilation.

B. Respiratory status: Following evacuation of a subdural hematoma, the client may be at risk for respiratory compromise due to factors such as altered consciousness, impaired airway reflexes, or postoperative complications. Assessing respiratory rate, depth, oxygen saturation, and presence of respiratory distress is essential for early detection and intervention.

C. Temperature: Monitoring temperature is important for detecting signs of infection or systemic complications, but it is not the priority assessment immediately following evacuation of a subdural hematoma.

D. Serum electrolytes: While monitoring serum electrolytes is important for overall assessment and management of the client's condition, it is not the priority assessment in the immediate postoperative period following evacuation of a subdural hematoma.

The client is most likely experiencing meningitis based on the following clinical manifestations:

1. Symptoms: The client presents with a 2-day history of lethargy, nausea, vomiting, anorexia, headache, general muscle aches, diarrhea, abdominal pain, sore throat, sensitivity to light, and intermittent nystagmus. These symptoms are consistent with the classic signs of meningitis, including headache, nausea, vomiting, photophobia, and altered mental status.
2. Physical Examination Findings: The physical examination reveals a fever (temperature of 38.9°C or 102°F), elevated heart rate (118/min), and signs of meningeal irritation such as neck stiffness (not directly mentioned but implied by headache and sensitivity to light). Additionally, a pinpoint, red, macular rash on the upper chest may indicate petechiae, which can be seen in meningococcal meningitis.

Given the suspicion of meningitis, the nurse should take the following actions:

1. Implement seizure precautions: Meningitis can lead to increased intracranial pressure and neurological complications, including seizures. Implementing seizure precautions involves ensuring the client's safety by padding the side rails of the bed, keeping the bed in a low position, and providing close observation.
2. Dim the lights in the client’s room: The client reports sensitivity to light, which is a common symptom of meningitis due to meningeal irritation. Dimming the lights can help reduce discomfort and photophobia in the client.

Parameters to Monitor:

1. Neurologic status: Monitoring the client's neurologic status is crucial for assessing the progression of meningitis and detecting any neurological deterioration, such as changes in level of consciousness, motor deficits, or signs of increased intracranial pressure.

2. Temperature: Monitoring the client's temperature is essential to assess for fever spikes or trends, which can indicate the severity of the infection and response to treatment.

Persistent or worsening fever may suggest inadequate treatment or complications such as abscess formation.
