He has had 1 L of NSS infused by emergency medical services. His vital signs reveal a pulse of 128 bpm and a blood pressure of 8860 mm Hg. With respect to his hypotension, the AGACNP recognizes that
Correct answer
C
Rationale
The correct answer is C: His blood pressure is likely a physiologic response to traumatic head injury.
Rationale:
1. Physiologic response: Traumatic head injury can lead to autonomic dysregulation, causing increased sympathetic activity and elevated blood pressure to maintain cerebral perfusion.
2. Compensation mechanism: The body may increase blood pressure in response to hypotension to ensure vital organs receive adequate blood flow.
3. Treatment consideration: Understanding that elevated blood pressure can be a compensatory mechanism helps guide appropriate management strategies for traumatic head injury patients.
Summary:
A: Vasopressors can be used in traumatic head injury depending on the specific situation, and they are not always contraindicated.
B: While hypotension can worsen outcomes in traumatic head injury, this choice overstates the risk without providing context.
D: Identifying the cause of hypotension is crucial in managing traumatic head injury patients and should not be disregarded in favor of stabilizing the head injury.
