A client admitted with an acute exacerbation of Ménière's disease asks the student nurse why he was prescribed diphenhydramine. Which response by the student nurse requires correction by the primary nurse?
"Ménière's disease is caused by an allergic response."
"This medication can help offset the nauseous feeling."
"Anticholinergics will help you rest."
"This medication can help reduce vomiting episodes."
The Correct Answer is A
Choice A Reason: This is incorrect because Ménière's disease is not caused by an allergic response. Ménière's disease is a disorder of the inner ear that causes vertigo, tinnitus, hearing loss, and a feeling of fullness in the ear. The exact cause of Ménière's disease is unknown, but it may be related to fluid imbalance, infection, trauma, or autoimmune reaction.
Choice B Reason: This is correct because diphenhydramine can help offset the nauseous feeling. Diphenhydramine is an antihistamine that blocks histamine receptors in the brain and inner ear, which can reduce nausea and vomiting associated with vertigo.
Choice C Reason: This is correct because anticholinergics will help you rest. Anticholinergics are a class of drugs that block acetylcholine receptors in the brain and body, which can have sedative effects and reduce motion sickness. Diphenhydramine has anticholinergic properties.
Choice D Reason: This is correct because diphenhydramine can help reduce vomiting episodes. As mentioned above, diphenhydramine can reduce nausea and vomiting by blocking histamine receptors in the brain and inner ear.

Correct Answer is A
Explanation
Choice A Reason: This is correct because the patient's Glasgow Coma Scale score is 9. The Glasgow Coma Scale is a tool that assesses the level of consciousness of a patient with a head injury by measuring three parameters: eye opening, verbal response, and motor response. The patient's eye opening score is 3 (opens eyes to verbal command), verbal response score is 4 (confused speech), and motor response score is 2 (withdraws from pain). The total score is the sum of these three scores, which is 9.
Choice B Reason: This is incorrect because the patient's Glasgow Coma Scale score is not 11. To get a score of 11, the patient would need to have a higher motor response score, such as 4 (withdraws to touch) or 5 (localizes to pain).
Choice C Reason: This is incorrect because the patient's Glasgow Coma Scale score is not 15. To get a score of 15, the patient would need to have the highest scores for all three parameters, such as 4 (opens eyes spontaneously), 5 (oriented speech), and 6 (obeys commands).
Choice D Reason: This is incorrect because the patient's Glasgow Coma Scale score is not 13. To get a score of 13, the patient would need to have a higher verbal response score, such as 5 (oriented speech).
Correct Answer is B
Explanation
Choice A reason: This is incorrect because loss of peripheral vision is not a manifestation of cataracts, but of glaucoma. Glaucoma is a condition that causes increased pressure inside the eye and damage to the optic nerve, which can lead to loss of vision in the outer edges of the visual field. The nurse should assess the client's intraocular pressure and visual field test results to rule out glaucoma.
Choice B reason: This is correct because a decreased ability to perceive colors is a manifestation of cataracts. Cataracts are a condition that causes clouding or opacity of the lens, which is the transparent structure behind the pupil that focuses light onto the retina. Cataracts can reduce the clarity and contrast of vision and make colors appear faded or yellowish. The nurse should ask the client about any changes in color perception or brightness of objects.
Choice C reason: This is incorrect because loss of central vision is not a manifestation of cataracts but of macular degeneration. Macular degeneration is a condition that affects the macula, which is the central part of the retina that is responsible for sharp and detailed vision. Macular degeneration can cause blurred or distorted central vision, difficulty reading or recognizing faces, or dark spots in the visual field. The nurse should assess the client's visual acuity and fundoscopic examination results to rule out macular degeneration.
Choice D reason: This is incorrect because seeing bright flashes of light and floaters is not a manifestation of cataracts but of retinal detachment. Retinal detachment is a condition that occurs when the retina, which is the layer of tissue at the back of the eye that converts light into nerve impulses, separates from its underlying support tissue. Retinal detachment can cause sudden flashes of light, floaters, or shadows in the visual field. The nurse should refer the client to an ophthalmologist immediately if retinal detachment is suspected.
