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 A
Explanation
A) Lordosis: This term specifically refers to an exaggerated inward curvature of the spine, particularly in the cervical or lumbar regions. When the nurse observes an exaggerated cervical curve, lordosis is the correct term to use for documentation, indicating a deviation from the normal spinal alignment.
B) Scoliosis: This condition is characterized by an abnormal lateral curvature of the spine. It does not apply to the observation of an exaggerated cervical curve and would not be appropriate for this finding.
C) Kyphosis: This term denotes an excessive outward curvature of the thoracic spine, often leading to a hunchback appearance. Since the assessment focuses on the cervical region, kyphosis would not accurately describe an exaggerated cervical curve.
D) Normal curve: This term refers to the expected, healthy curvature of the spine. Documenting an exaggerated curve as "normal" would be misleading and does not accurately reflect the observed condition. The nurse should document the finding as lordosis to convey the specific abnormality noted.
Correct Answer is B
Explanation
A) Posterior superior iliac spine: While this landmark is useful for certain assessments, it is more commonly used to identify pelvic alignment rather than symmetry of the spine itself.
B) Iliac crests: The iliac crests serve as an important anatomical landmark for assessing symmetry in the posterior spine. By comparing the heights of the iliac crests on both sides, the nurse can determine any asymmetry in the pelvis and, by extension, the spine, as uneven heights may indicate spinal deformities.
C) Paravertebral muscles: While assessing the paravertebral muscles can provide information about muscle tone and potential asymmetries, they are not direct landmarks for evaluating overall spinal symmetry.
D) Twelfth thoracic vertebrae: Although identifying specific vertebrae is important for certain assessments, the twelfth thoracic vertebra is not commonly used as a primary landmark for assessing symmetry in the spine. It is more useful for locating the general area of the thoracic spine.
