During the assessment of a client's head and neck, the nurse observes the client's facial expressions and the face for symmetry and movement. Which cranial nerve is the nurse assessing?
VII
V
III
VI
The Correct Answer is A
A) VII: The facial nerve (cranial nerve VII) is responsible for controlling the muscles of facial expression. By assessing facial symmetry and movement, the nurse evaluates the integrity and function of this nerve, which is crucial for activities such as smiling, frowning, and raising eyebrows.
B) V: The trigeminal nerve (cranial nerve V) is primarily responsible for sensation in the face and motor functions such as chewing. While it plays a role in facial movement, it does not specifically assess facial expressions.
C) III: The oculomotor nerve (cranial nerve III) controls eye movement and pupil constriction. It does not directly influence facial expressions, so it is not the nerve being assessed in this context.
D) VI: The abducens nerve (cranial nerve VI) is responsible for lateral eye movement. It is unrelated to facial expression or symmetry and is not the focus of this assessment.

Correct Answer is C
Explanation
A) "The client may be having a cardiac event": While this statement indicates a potential concern, it lacks specific details about the client's current condition. It suggests a possibility but does not clearly communicate the immediate issue or symptoms being experienced.
B) "The client needs an EKG. Please see her immediately": This statement expresses urgency and a request for action but does not provide the necessary context or information about the client's symptoms. It is more aligned with the "Request" part of SBAR rather than the "Situation."
C) "The client is experiencing chest pain and shortness of breath": This statement accurately describes the current situation the client is facing. It provides essential information regarding the symptoms the nurse is observing, making it a clear example of the "Situation" in the SBAR framework. This information is critical for the provider to understand the urgency of the situation.
D) "The client's admitting diagnosis is stage 2 breast cancer": While this statement provides important background information, it does not reflect the immediate situation that requires attention. It does not address the current health issue that is prompting the nurse to contact the provider.
Correct Answer is C
Explanation
A) Motor component of IV (Trochlear): The trochlear nerve primarily controls the superior oblique muscle of the eye, which is responsible for downward and lateral eye movements. The findings described do not relate to eye movement and therefore do not indicate dysfunction of this nerve.
B) Motor and sensory components of XI (Accessory): The accessory nerve innervates the sternocleidomastoid and trapezius muscles, primarily affecting head rotation and shoulder elevation. The symptoms noted in the assessment do not pertain to these muscle functions, so this option is not correct.
C) Motor component of VII (Facial): The signs of asymmetry in frowning, uneven eyebrow lifting, sagging eyelids, and air escaping when puffing the cheeks are characteristic of dysfunction in the facial nerve (cranial nerve VII). This nerve controls the muscles of facial expression, and impairment would lead to the described asymmetrical movements.
D) Motor component of X (Vagus) and sensory component of XII (Hypoglossal): The vagus nerve affects autonomic functions and some swallowing muscles, while the hypoglossal nerve controls tongue movements. Neither nerve is primarily responsible for the facial expressions described in the assessment findings, making this option incorrect.
