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
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 A
Explanation
Choice A reason: This statement reflects denial, which is a common initial reaction in the grief process. The client is not accepting the reality of their prognosis and believes the doctor is exaggerating. Denial serves as a defense mechanism to protect the individual from the emotional impact of the diagnosis. It is a way for the client to cope with the overwhelming news by rejecting its truth.
Choice B reason: This statement reflects anger, another stage in the grief process. The client is expressing disbelief and frustration towards the doctor’s competence. Anger often follows denial and is directed towards others as a way to cope with the emotional pain. It is not indicative of denial but rather a progression in the grieving process.
Choice C reason: This statement reflects acceptance of the physical symptoms and the reality of the client’s condition. The client acknowledges their lack of energy and the impact of the illness on their daily life. This is not a sign of denial but rather an acceptance of their current state.
Choice D reason: This statement reflects acceptance and gratitude towards the doctor. The client recognizes the efforts made by the healthcare team and accepts that their time is limited. This is a sign of acceptance, the final stage in the grief process, where the individual comes to terms with their situation.
Correct Answer is A
Explanation
Choice A Reason:
Loperamide should not be used if diarrhea is infectious is correct. Loperamide is an antidiarrheal medication that works by slowing down gut movement. However, if the diarrhea is caused by an infection, such as from spoiled food, it is important to allow the body to expel the infectious agents. Using loperamide in such cases can prolong the infection and potentially worsen the condition.
Choice B Reason:
You can take loperamide until the diarrhea stops is incorrect. While loperamide can be effective for non-infectious diarrhea, it is not recommended for infectious diarrhea. Stopping the diarrhea prematurely can trap the infectious agents in the intestines, leading to more severe symptoms.
Choice C Reason:
Loperamide has no side effects is incorrect. Loperamide can have side effects, including constipation, dizziness, and abdominal pain. It is important to use this medication under the guidance of a healthcare provider, especially in cases of infectious diarrhea.
Choice D Reason:
Loperamide should not stop this type of diarrhea is incorrect. While it is true that loperamide should not be used for infectious diarrhea, the statement is misleading. Loperamide can stop diarrhea, but it is not appropriate for all types of diarrhea, particularly those caused by infections.
