A nurse is caring for a client who has increased intracranial pressure and has a worsening neurological condition. Which of the following cues should the nurse recognize as a worsening condition?

Choice A rationale A blood pressure of 100/70 mm Hg, while potentially lower than a client's baseline, does not directly indicate worsening intracranial pressure (ICP) in isolation. Worsening ICP often presents with Cushing's triad: hypertension (increased systolic pressure), bradycardia, and irregular respirations. A normal blood pressure range is typically 90/60 mm Hg to 120/80 mm Hg. This reading is within normal limits and doesn't suggest acute deterioration. Choice B rationale An increased intracranial pressure (ICP) is the underlying problem, not a direct cue of *worsening* condition in terms of a specific neurological sign. While elevated ICP is the pathology, the question asks for *cues* of worsening. Normal ICP ranges from 5 to 15 mmHg. A sustained increase above this range indicates worsening cerebral perfusion and potential herniation. Choice C rationale A decreasing Glasgow Coma Scale (GCS) score is a critical indicator of worsening neurological function. The GCS assesses eye opening, verbal response, and motor response, providing a quantitative measure of consciousness. A decrease in the score signifies a deterioration in brain function, often due to increasing ICP compromising cerebral blood flow and neuronal activity. Choice D rationale A respiratory rate of 12/min is within the normal adult range (12 to 20 breaths per minute). While changes in respiratory patterns, such as Cheyne-Stokes or Kussmaul respirations, are indicative of neurological deterioration, a normal rate alone does not signal worsening intracranial pressure or neurological status.
