Brimonidine is used to lower IOP in clients with open-angle glaucoma or ocular hypertension. Gatifloxacin is an antibiotic. Betaxolol is a beta-adrenergic blocking drug used for chronic open-angle glaucoma and ocular hypertension.

A nurse is caring for a client who is prescribed 1% hydrocortisone/4.71 mg neomycin for bacterial infection of the external auditory canal. Which instructions should the nurse utilize when administering the otic solution? A) With the client upright, remove the solution running out of the ear with gauze. B) After instilling the drops, insert a cotton piece deep into the ear to keep the drops in. C) Keep the client lying on the untreated side for 30 minutes after instilling the drops. D) Insert the applicator or dropper tip sufficiently to reach into the external auditory canal. Answer: A Rationale: Once the client is upright, the solution running out of the ear may be gently removed with gauze. A piece of cotton can be loosely inserted into the ear canal, but it should never be inserted deeply because if inserted too deeply it may cause increased pressure within the ear canal. The client is kept lying on the untreated side after the medication is instilled for approximately 5 minutes to facilitate the penetration of the drops into the ear canal. The nurse should not insert the applicator or dropper tip anywhere into the ear or allow the tip to become contaminated. Question format: Multiple Cho
