What is a priority nursing intervention for a client with suspected head trauma?

Monitoring for increased intracranial pressure (ICP) is critical for a client with suspected head trauma because head injuries can lead to swelling or bleeding in the brain, resulting in elevated pressure within the cranial cavity. Increased ICP can cause further brain injury, decreased cerebral perfusion, and can be life-threatening.

By closely monitoring for signs and symptoms of increased ICP, such as changes in consciousness, pupil reaction, or changes in vital signs, the nurse can implement timely interventions to manage the condition, which can include elevating the head of the bed, maintaining airway patency, and administering medications as prescribed to help reduce the pressure.

The other choices do not directly address the immediate risks associated with head trauma. Administering anticoagulants could pose a risk of exacerbating bleeding. Encouraging fluid intake is generally not a priority before establishing the patient's neurological status and addressing potential complications like ICP. Performing passive movements is not relevant in the acute setting of head trauma, where the focus should be on maintaining stability and monitoring neurological status.
