The nurse is performing a neurologic assessment on a client diagnosed with a stroke and cannot elicit a gag reflex. This deficit is related to which of the following cranial nerves?

Trigeminal nerve.

Facial nerve.

Glossopharyngeal nerve.

Vagus nerve.

Answer and Explanation

Correct Answer : C,D

Choice A rationale

The trigeminal nerve is responsible for facial sensation and motor functions like chewing, not related to gag reflex impairment.

Choice B rationale

The facial nerve controls facial expressions, taste sensations, and other functions but does not influence the gag reflex.

Choice C rationale

The glossopharyngeal nerve (cranial nerve IX) plays a crucial role in the gag reflex as it innervates part of the pharynx and is responsible for sensory functions in the throat.

Choice D rationale

The vagus nerve (cranial nerve X) also contributes to the gag reflex, providing motor innervation to the pharyngeal muscles and aiding in swallowing and speech functions.

Correct Answer is C

Explanation

Choice A rationale

Furuncles, also known as boils, are deep folliculitis caused by bacterial infection, not sebum blockage.

Choice B rationale

Carbuncles are clusters of furuncles connected under the skin and are also caused by bacterial infection, not sebum blockage.

Choice C rationale

Comedones are primary lesions of acne caused by the blockage of hair follicles by sebum and keratin. They can be open (blackheads) or closed (whiteheads).

Choice D rationale

Striae, also known as stretch marks, are caused by the tearing of the dermis due to rapid stretching of the skin and are not related to sebum blockage in hair follicles.

A. It is a test for motor ability. B. It is a test for balance. C. It is a test for coordination. D. It is a test for muscle strength.

Correct Answer is B

Explanation

Choice A rationale

The Romberg test does not assess motor ability. Motor ability tests typically involve assessing muscle strength, coordination, and movement.

Choice B rationale

The Romberg test is used to assess balance. It evaluates the client's ability to maintain a steady position with eyes closed, indicating the integrity of the proprioceptive and vestibular systems.

Choice C rationale

The Romberg test does involve coordination, but its primary focus is on balance rather than coordination alone. Coordination tests usually involve tasks requiring fine motor control.

Choice D rationale

The Romberg test does not assess muscle strength. Muscle strength tests involve evaluating the force generated by muscles during contraction.
