Which finding is most indicative of increasing intracranial pressure in a client with a severe head injury?

• A. Increased restlessness
• B. Decreased heart rate
• C. Fixed dilated pupils
• D. High fever

Answer: (A)

In the context of a severe head injury, increased restlessness is a key indicator of increasing intracranial pressure (ICP). When pressure builds within the skull as a result of swelling, bleeding, or other complications following an injury, the brain's function can become increasingly compromised. Early changes due to elevated ICP can manifest as behavioral changes, including restlessness or irritability, as the individual experiences discomfort or changes in mental status. Restlessness may reflect the brain's struggle to cope with the pressure and can be one of the first signs observed before more severe and definitive symptoms appear. Monitoring for changes in activity level or behavior is crucial in patients with head injuries, as these can provide timely insight into the state of their neurological function and the potential need for intervention. Other findings that may indicate increasing ICP include fixed dilated pupils, decreased heart rate, and high fever, but they are typically considered late signs or signs that have other implications. For instance, fixed and dilated pupils usually indicate significant pressure on the brainstem and can signal a more advanced state of pressure elevation, which may not occur as early or may indicate a more critical situation.
