During recovery from a cerebrovascular accident (CVA), a female client is given nothing by mouth, to help prevent aspiration. To determine when the client is ready for a liquid diet, the nurse assesses the client’s swallowing ability once each shift. This assessment evaluates:
a. cranial nerves I and II.
b. cranial nerves III and V.
c. cranial nerves VI and VIII.
d. cranial nerves IX and X.
Answer D.
Swallowing is a motor function of cranial nerves IX and X. Cranial nerves I, II, and VIII don’t possess motor functions. The motor functions of cranial nerve III include extraocular eye movement, eyelid elevation, and pupil constriction. The motor function of cranial nerve V is chewing. Cranial nerve VI controls lateral eye movement.
