Which manifestation is the most problematic for the client diagnosed with Ménière disease? Vertigo Explanation: Vertigo is usually the most troublesome complaint related to Ménière disease. Other clinical manifestations include tinnitus, diaphoresis, and hearing loss. Which of the following instructions, regarding swimming, should the nurse give to the client who is recovering from otitis externa? Choose the correct option. Wear soft plastic ear plugs. Explanation: The nurse should advise the client to wear soft plastic ear plugs to prevent trapping water in the ear while swimming. Which of the following classification of medications is the most common cause of ototoxicity? Aminoglycosides Explanation: IV medications, especially the aminoglycosides, are the most common cause of ototoxicity, and they destroy the hair cells in the organ of Corti. Cephalosporins, sulfonamides, and penicillins are not among the most common causes of ototoxicity. High doses of which medication can produce bilateral tinnitus? Aspirin Explanation: At high doses, aspirin toxicity can produce bilateral tinnitus. Meclizine and dimenhydrinate are used for nausea and vomiting related to motion sickness.

Which symptoms may a client with Ménière disease report before an attack? A full feeling in the ear Explanation: Clients with Ménière disease experience symptoms of headache and a full feeling in the ear before an attack. Nystagmus is an episodic symptom that occurs during an attack, and, at times, the client is symptom free. Ménière disease does not cause low blood pressure or photosensitivity. The nurse is developing a plan of care for a client with Meniere's disease and identifies a nursing diagnosis of excess fluid volume related to fluid retention in the inner ear. Which intervention would be most appropriate to include in the plan of care? Limit foods that are high in sodium. Explanation: Sodium and fluid retention disrupts the delicate balance between the endolymph and perilymph in the inner ear. Therefore, many clients can control their symptoms by adhering to a low-sodium diet. Caffeinated fluids are to be avoided because of their diuretic effect. Diuretics, not antihistamines, would be prescribed to lower the pressure in the endolymphatic system. Foods high in potassium would be encouraged if the client is prescribed a diuretic that causes potassium loss. A client who has been fitted with a hearing aid comes for a follow-up evaluation. During the visit, the client states, "I've noticed that I still don't seem to hear well enough. The hearing aid doesn't seem to make the sounds louder." Which of the following might the nurse determine as the possible cause?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
