A client had an evacuation of a subdural hematoma. Which of the following actions should the nurse take first?
- A. Observe for cerebrospinal fluid (CSF) leaks from the evacuation site.
- B. Assess for an increase in temperature.
- C. Check the oximeter.
- D. Monitor for manifestations of increased intracranial pressure.
Correct Answer: C
Rationale: Step 1: Checking the oximeter is essential to assess the client's oxygen saturation levels immediately post-procedure.
Step 2: Hypoxia can lead to serious complications, impacting the client's neurological status.
Step 3: The nurse must prioritize oxygenation status to prevent further brain injury or hypoxemia.
Step 4: Observing for CSF leaks, assessing temperature, and monitoring ICP are important but not as immediate as ensuring adequate oxygen supply.
Summary: Option C is correct as it addresses the most critical and immediate concern post-procedure, ensuring optimal oxygenation for the client's neurological recovery. Options A, B, and D are important but secondary to maintaining oxygen levels.
