When inspecting the ears for cerumen impaction, the nurse checks for which finding?

Correct Answer: D

Rationale: When inspecting the ears for cerumen impaction, the nurse should look for a yellowish or brownish waxy material in the external auditory canal. Cerumen, also known as ear wax, is a secretion that can become impacted due to various reasons. It is produced by the vestigial apocrine sweat glands in the external ear canal. Cerumen may partially obscure the eardrum or totally occlude the ear canal. The other options, redness and swelling of the tympanic membrane, an external auditory canal that is longer than normal, and the presence of edema in the external auditory canal, are not indicative findings of cerumen impaction.

Correct Answer: D

Rationale: To assess the function of cranial nerve XI (spinal accessory nerve), the nurse examines the sternomastoid and trapezius muscles for equal size and strength. The correct method involves asking the client to rotate the head forcibly against resistance to the side of the chin and to shrug the shoulders against resistance from the nurse's hands. Choice A, asking the client to stick out the tongue and watching for tremors, is used to assess cranial nerve XII (hypoglossal nerve). Choice C, depressing the client's tongue with a tongue blade and noting pharyngeal function as the client says 'ah', is the technique for examining cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). Choice B, touching the posterior pharyngeal wall with a tongue blade and noting the gag reflex, is used to evaluate cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve), not cranial nerve XI.

Correct Answer: C

Rationale: To assess the function of cranial nerve I (olfactory nerve), the nurse uses a wisp of cotton to test the sense of smell in a client who reports loss of smell. The nurse assesses the patency of the client's nostrils by occluding one nostril at a time and asking the client to sniff. Next, with the client's eyes closed, the nurse occludes one nostril and presents a non-noxious aromatic substance such as coffee, toothpaste, orange, vanilla, soap, or peppermint. Choice A, 'Coffee,' is incorrect because it is used to present non-noxious aromatic substances to assess cranial nerve I. Choice B, 'A tuning fork,' is used to assess the function of cranial nerve VIII (acoustic nerve). Choice D, 'An ophthalmoscope,' is used to assess the internal structures of the eye, not cranial nerve I.

Correct Answer: D

Rationale: The correct answer is cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). When the nurse touches the posterior pharyngeal wall with a tongue blade and elicits the gag reflex, it indicates normal function of these nerves. Cranial nerves V (trigeminal nerve) and VI (abducens nerve) are not directly responsible for the gag reflex. Cranial nerves XII (hypoglossal nerve) and VIII (vestibulocochlear nerve) are not directly involved in eliciting the gag reflex. Testing cranial nerve I involves smell function, and cranial nerve II is related to eye examinations, making them irrelevant in this scenario.

Correct Answer: D

Rationale: The correct answer is cranial nerve XII (hypoglossal nerve). When testing cranial nerve XII, the healthcare provider inspects the symmetry and movement of the tongue. The tongue should protrude in the midline when the client sticks it out. Cranial nerve IX (glossopharyngeal nerve) and X (vagus nerve) are tested by depressing the tongue with a blade to observe pharyngeal movement and gag reflex. Cranial nerve V (trigeminal nerve) is responsible for testing the muscles of mastication, not tongue protrusion.
