During an assessment of the cranial nerves (CNS), the nurse finds the following asymmetry when the client smiles or frowns, uneven lifting of the eyebrows, and escape of air when the nurse presses against the right puffed cheek. The nurse recognized that these findings indicate dysfunction of which cranial nerve(s)?
Motor component of CN X and sensory component of CN VII
Motor and sensory component of CN XI
Motor component of CN IV
Motor component of CN VII
The Correct Answer is D
A. Dysfunction of the motor component of CN X (vagus nerve) and sensory component of CN VII (facial nerve) would present with different symptoms, such as difficulty swallowing and impaired taste sensation, not the observed facial asymmetry and puffing of cheeks.
B. CN XI (accessory nerve) dysfunction primarily affects the sternocleidomastoid and trapezius muscles and wouldn't cause the observed facial asymmetry.
C. Dysfunction of CN IV (trochlear nerve) leads to issues with downward and inward eye movement, not the facial asymmetry described.
D. Dysfunction of the motor component of CN VII (facial nerve) leads to facial asymmetry during expressions and difficulty controlling facial muscles, which matches the observed findings.
