A nurse is teaching a client about diagnostic vision tests. The nurse should include that which of the following tests is performed to diagnose macular degeneration?

Choice A reason: This is incorrect because it is necessary to remove contact lenses before administering medications. Contact lenses can absorb or interfere with the absorption of eye drops and cause irritation or infection. The nurse should instruct the client to remove contact lenses before applying eye drops and wait at least 15 minutes before reinserting them.
Choice B reason: This is incorrect because administering the medications by touching the tip of the dropper to the sclera of the eye can cause contamination or injury. The sclera is the white part of the eye that covers most of the eyeball. The nurse should instruct the client to avoid touching the tip of the dropper to any part of the eye or eyelid and hold it about 1 cm above the lower eyelid.
Choice C reason: This is correct because administering the medications 5 min apart can prevent dilution or washout of one medication by another. Timolol and pilocarpine are two different types of eye drops that are used to treat open-angle glaucoma, which is a condition that causes increased pressure inside the eye and damage to the optic nerve. Timolol is a beta-blocker that reduces the production of fluid in the eye, and pilocarpine is a cholinergic agent that increases the drainage of fluid from the eye. The nurse should instruct the client to apply one drop of each medication in the affected eye(s) and wait at least 5 minutes between each medication.
Choice D reason: This is incorrect because holding pressure on the conjunctival sac for 2 min following the application of eye drops can reduce systemic absorption and side effects of eye drops. The conjunctival sac is the space between the lower eyelid and the eyeball. The nurse should instruct the client to gently close their eyes after applying eye drops and press their index finger against the inner corner of their eye for 2 minutes. This can block the tear duct that drains fluid from the eye to the nose and prevent it from entering the bloodstream.

Choice A reason: This is incorrect because administering IV ketorolac is not a priority intervention for a client with cholecystitis. Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that can cause gastrointestinal bleeding and kidney damage, which are contraindicated in cholecystitis. The nurse should administer analgesics as prescribed, but only after assessing the pain level and severity.

Choice B reason: This is incorrect because reporting findings to healthcare provider is not a priority intervention for a client with cholecystitis. The nurse should communicate with the healthcare provider about the client's condition and treatment plan, but only after assessing the pain level and other vital signs.

Choice C reason: This is incorrect because offering a high-calorie, high-fat meal is not an intervention for a client with cholecystitis, but a potential trigger. High-fat foods can stimulate the gallbladder to contract and cause more pain and inflammation. The nurse should advise the client to avoid fatty foods and follow a low-fat diet.

Choice D reason: This is the correct answer because assessing the pain level is a priority intervention for a client with cholecystitis. Pain is the most common symptom of cholecystitis and can indicate the severity and complications of the condition. The nurse should assess the pain level using a numeric or descriptive scale, and monitor for changes in location, intensity, and duration.
