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 the correct answer because this describes a stupor, which is a state of near-unconsciousness or reduced responsiveness. A stuporous client shows minimal movement and verbal responses and requires extreme vigorous stimulation such as painful stimuli to awaken briefly.
Choice B reason: This is incorrect because this describes obtundation, which is a state of reduced alertness or awareness. An obtunded client is extremely drowsy and minimally responsive and requires vigorous stimulation such as shaking or shouting to wake.
Choice C reason: This is incorrect because this describes lethargy, which is a state of decreased energy or activity. A lethargic client is alert and oriented x3 (to person, place, and time), but sluggish and drowsy, and wakes to voice or gentle shaking.
Choice D reason: This is incorrect because this describes a coma, which is a state of deep unconsciousness or unresponsiveness. A comatose client does not respond to verbal stimuli or speak and shows abnormal posturing in response to pain, such as decorticate (flexion of arms and extension of legs) or decerebrate (extension of arms and legs).
Correct Answer is B
Explanation
Choice A Reason: An antifungal cream is not indicated for a sty, which is an infection of the eyelash follicle or sebaceous gland caused by bacteria.
Choice B Reason: This is the correct answer because warm compresses can help relieve pain and inflammation, and promote drainage of the sty.
Choice C Reason: Ice and cold compresses are not recommended for a sty, as they can constrict blood vessels and delay healing.
Choice D Reason: There is no need to test the other eye for vision loss, as a sty does not affect vision unless it is very large or obstructs the pupil.
