Which assessment information is most concerning to the nurse when caring for a patient with head injury?

• A. The blood pressure increases from 120/54 to 136/62.
• B. The patient complains of a headache at pain level 5 of a 10-point scale.
• C. The patient's apical pulse is slightly irregular.
• D. The patient is more difficult to arouse.

Answer: (D)

A worsening level of consciousness is the most concerning sign in a patient with head injury because it directly reflects rising intracranial pressure and potential brain herniation. When ICP increases, cerebral perfusion pressure drops unless blood pressure rises enough to compensate; this leads to brain tissue hypoxia and further edema. A patient who becomes harder to arouse signals that the brain is not maintaining wakefulness and may be undergoing dangerous neurological deterioration, requiring immediate assessment and intervention. Other findings like a modest blood pressure increase, a headache of moderate intensity, or an irregular pulse can occur for various reasons and are less specific to acute intracranial pathology. They do not indicate the urgent, evolving neuro status change that a decreased level of arousal does. In this situation, prioritize airway and oxygenation, ensure the head is midline with the bed elevated to about 30 degrees, and obtain urgent neuro checks and escalation of care to prevent further deterioration.
