An appropriate nursing intervention for a patient at risk for ineffective cerebral tissue perfusion related to cerebral edema is:

• A. Avoid neck and hip flexion
• B. Lower PaCO2 to 15-20 mm Hg
• C. Cluster nursing activities to provide periods of uninterrupted rest
• D. Routine suctioning to prevent accumulation of secretions

Answer: (A)

Maintaining neutral head and neck alignment to promote venous drainage from the brain is essential. In cerebral edema, elevated intracranial pressure can impair cerebral perfusion. If the neck or hips are flexed, venous outflow from the brain can be impeded, causing ICP to rise and cerebral perfusion to worsen. Keeping the head in a midline, neutral position and avoiding hip flexion helps maintain unobstructed venous return, helps keep ICP lower, and preserves cerebral perfusion pressure (the pressure driving blood flow to the brain). Lowering PaCO2 to an extremely low level would cause cerebral vasoconstriction and reduce blood flow to the brain, which is dangerous and not appropriate as a routine measure. While clustering care to reduce agitation can help stabilize ICP, and routine suctioning can provoke coughing and transient ICP spikes, the direct, best protective action is positioning that favors venous drainage.
