A 64-year-old female found on the floor of her apartment has apparently fallen and hit her head on the bathtub. On admission to the neurologic unit, she has a decreased level of consciousness

Question

The physician orders positioning as follows: elevate the head of the bed; keep the head in neutral alignment with no neck flexion or head rotation; avoid sharp hip flexion. Which of the following is the best rationale for this positioning?
A) To decrease cerebral arterial pressure
B) To avoid impeding venous outflow
C) To prevent flexion contractures
D) To prevent aspiration of stomach contents

Answer 1

Ans: B
Feedback: Any activity or position that impedes venous outflow from the head may contribute to increased volume inside the skull and possibly increase intracranial pressure. Cerebral arterial pressure will be affected by the balance between oxygen and carbon dioxide. Flexion contractures aren't a priority at this time. Stomach contents could possibly be aspirated in the position ordered by the physician.
