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) Idiopathic neuropathy has no known cause: This statement is accurate, as idiopathic neuropathy refers to nerve damage for which no specific cause can be identified despite thorough investigation. The term "idiopathic" literally means "of unknown origin," indicating that the underlying mechanism remains unclear.
B) Idiopathic neuropathy is hereditary in nature: While some neuropathies can be hereditary, idiopathic neuropathy itself is not classified as hereditary since it lacks a defined genetic cause. Hereditary neuropathies are specific types that have a genetic basis.
C) Idiopathic neuropathy is caused by nutritional deficits: Nutritional deficits can lead to various types of neuropathy, but idiopathic neuropathy specifically is characterized by the absence of a known cause. Therefore, attributing it to nutritional deficits would be incorrect.
D) Idiopathic neuropathy is caused by disease or illness: While certain diseases can cause neuropathy, the key characteristic of idiopathic neuropathy is that no specific disease or illness has been identified as the cause. This differentiates it from other neuropathies that are secondary to identifiable conditions.
Correct Answer is C
Explanation
A) Notify the healthcare provider that the client is exaggerating their pain: It is inappropriate for the nurse to assume that the client is exaggerating their pain based solely on their demeanor. Pain perception is subjective and can vary greatly among individuals, especially in conditions like sickle cell anemia.
B) Wait 30 minutes and see if the client is still requesting pain medication: Delaying pain relief can lead to unnecessary suffering. Given that the client rates their pain as a 7 out of 10, which indicates significant discomfort, it is essential to address their pain promptly rather than postponing treatment.
C) Administer the pain medication as prescribed: This is the most appropriate action. Clients with sickle cell anemia often experience severe pain crises, and effective pain management is crucial. Administering the medication as prescribed supports the client's comfort and well-being.
D) Administer half of the ordered dose of pain medication: Modifying the dosage without a provider's order is not appropriate. If the full prescribed dose is warranted based on the pain level, the nurse should administer it as indicated to ensure effective pain management.
