A nurse is caring for a client who had a stroke involving the right cerebral hemisphere. The nurse should monitor for which of the following findings?

Choice A reason: Eliciting the gag reflex is not a valid way to assess cranial nerve III. The gag reflex is a protective mechanism that prevents choking or aspiration by triggering a contraction of the pharyngeal muscles when the back of the throat is stimulated. The gag reflex is mediated by cranial nerves IX and X, not III.

Choice B reason: Checking the pupillary response to light is a reliable way to assess cranial nerve III. The pupillary response to light is a reflex that causes the pupil to constrict when exposed to bright light and dilate when exposed to dim light. This reflex helps to regulate the amount of light that enters the eye and protects the retina from damage. The pupillary response to light is controlled by cranial nerve III, which innervates the sphincter pupillae muscle that constricts the pupil.

Choice C reason: Observing for facial symmetry is not a relevant way to assess cranial nerve III. Facial symmetry is the degree of similarity between the two halves of the face. Facial symmetry can be affected by various factors, such as genetics, aging, or facial nerve palsy. Facial nerve palsy is a condition that causes weakness or paralysis of the muscles that control facial expression. Facial nerve palsy is caused by damage to cranial nerve VII, not III.

Choice D reason: Testing visual acuity is not a sufficient way to assess cranial nerve III. Visual acuity is the ability to see fine details and distinguish objects at a distance. Visual acuity depends on various factors, such as the clarity of the lens and cornea, the shape of the eyeball, and the function of the retina. Visual acuity is mainly affected by cranial nerve II, which carries visual information from the retina to the brain. Cranial nerve III does not directly influence visual acuity, but it does innervate some of the muscles that move the eye and enable binocular vision.

Choice A reason: Placing suction equipment at the client’s bedside is a necessary action for the nurse to take for a client who has right sided acoustic neuroma resulting in impairment of cranial nerves IX and X. Acoustic neuroma is a noncancerous tumor that develops on the vestibulocochlear nerve, which is responsible for hearing and balance. It can also affect the adjacent cranial nerves, such as the glossopharyngeal (CN IX) and the vagus (CN X) nerves, which are involved in swallowing and gagging. A client with acoustic neuroma may have difficulty swallowing and clearing secretions, which can increase the risk of aspiration and respiratory infections. The nurse should have suction equipment ready to remove any excess saliva or mucus from the client’s mouth or throat.

Choice B reason: Avoiding the use of warm water to wash the client’s face is not a relevant action for the nurse to take for a client who has right sided acoustic neuroma resulting in impairment of cranial nerves IX and X. The temperature of the water does not affect the function of these nerves or the tumor. The nurse should use gentle and appropriate hygiene measures to clean the client’s face and prevent skin breakdown.

Choice C reason: Providing range of motion exercises to the client’s neck and shoulders is not a priority action for the nurse to take for a client who has right sided acoustic neuroma resulting in impairment of cranial nerves IX and X. Range of motion exercises can help to maintain joint mobility and prevent stiffness, but they are not directly related to the cranial nerve impairment or the tumor. The nurse should consult with a physical therapist to determine the best exercise regimen for the client.

Choice D reason: Applying an eye patch to the client’s right eye is not a helpful action for the nurse to take for a client who has right sided acoustic neuroma resulting in impairment of cranial nerves IX and X. An eye patch is used to protect the eye from injury or infection, or to treat conditions such as strabismus or amblyopia. An eye patch does not affect the function of the cranial nerves IX and X or the tumor. The nurse should monitor the client’s eye movements and vision, as acoustic neuroma can also affect the facial (CN VII) and oculomotor (CN III) nerves, which are involved in blinking and eye movement.
