A nurse is assessing a client’s cranial nerves. What cranial nerve would be assessed when checking a client’s gag reflex?

CN IX

CN V

CN X

CN XII

Answer and Explanation

The Correct Answer is A

Choice A reason: The glossopharyngeal nerve (CN IX) is primarily responsible for the gag reflex. It provides sensory input from the pharynx and posterior third of the tongue, which triggers the gag reflex when stimulated. This nerve plays a crucial role in swallowing and the reflexive action to prevent choking.

Choice B reason: The trigeminal nerve (CN V) is responsible for facial sensation and motor functions such as biting and chewing. It does not play a direct role in the gag reflex. While it is important for other sensory and motor functions, it is not involved in the reflex being assessed here.

Choice C reason: The vagus nerve (CN X) also contributes to the gag reflex by providing motor innervation to the muscles of the pharynx and larynx. However, the primary sensory input for the gag reflex comes from the glossopharyngeal nerve (CN IX). The vagus nerve works in conjunction with CN IX to complete the reflex action.

Choice D reason: The hypoglossal nerve (CN XII) controls the movements of the tongue. It is essential for speech and swallowing but does not have a role in the gag reflex. The hypoglossal nerve’s primary function is motor control of the tongue muscles.

Correct Answer is C

Explanation

Choice A Reason:

Asking “When did you begin to have trouble sleeping?” is important for understanding the onset and duration of the client’s insomnia. However, it does not directly address immediate safety concerns. Chronic insomnia can lead to significant daytime impairment, but the question about the onset of sleep troubles does not identify specific safety risks.

Choice B Reason:

Inquiring about specific factors affecting the client’s ability to sleep can help identify potential causes of insomnia, such as stress, environmental factors, or medical conditions. While this information is valuable for treatment planning, it does not directly address immediate safety concerns.

Choice C Reason:

Asking “Do you have difficulty staying awake when you are driving?” addresses the highest safety priority. Chronic insomnia can lead to excessive daytime sleepiness, which significantly increases the risk of accidents, especially while driving. Identifying whether the client is at risk of falling asleep during potentially dangerous activities is crucial for immediate safety.

Choice D Reason:

Understanding the client’s bedtime routine can provide insights into their sleep hygiene and habits, which are important for managing insomnia. However, this question does not directly address immediate safety concerns related to daytime functioning and the risk of accidents.

A. Date of birth B. Photograph identification C. Facility room number D. Client’s full name

Correct Answer is ["A","D"]

Explanation

Choice A Reason:

Date of birth is an acceptable client identifier. The Joint Commission specifies that using the date of birth helps ensure accurate identification of the client. This identifier is unique to each individual and is less likely to be duplicated.

Choice B Reason:

Photograph identification is not typically listed as an acceptable identifier by the Joint Commission. While it can be useful in some settings, it is not one of the primary identifiers recommended for ensuring patient safety.

Choice C Reason:

Facility room number is not an acceptable client identifier. The Joint Commission explicitly states that room numbers should not be used as identifiers because they can change and are not unique to the individual.

Choice D Reason:

Client’s full name is an acceptable client identifier. Using the full name helps to accurately identify the client and match them with their medical records and treatment plans.
