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: Providing written materials and visual aids is not necessary for a client who has hearing at 15 dB, which is considered normal hearing. Normal hearing ranges from 0 to 20 dB, meaning that the person can hear sounds that are as faint as 20 dB or less.

Choice B Reason: Using American Sign Language is not appropriate for a client who has hearing at 15 dB, which is considered normal hearing. American Sign Language is a form of communication that uses hand gestures, facial expressions, and body movements to convey meaning. It is mainly used by people who are deaf or hard of hearing.

Choice C Reason: Shouting at the client from 6 inches away is not advisable for a client who has hearing at 15 dB, which is considered normal hearing. Shouting can be perceived as rude or aggressive, and can damage the hearing of both the speaker and the listener.

Choice D Reason: Speaking to the client in an everyday conversational tone is the best action for a client who has hearing at 15 dB, which is considered normal hearing. Conversational speech ranges from 40 to 60 dB, meaning that the person can hear sounds that are as loud as 60 dB or less.

Choice A reason: This is incorrect because applying the medication when you are experiencing eye pain can be ineffective or harmful for treating open-angle glaucoma. Open-angle glaucoma is a chronic condition that causes increased pressure inside the eye and damage to the optic nerve, which can lead to vision loss. Eye pain is not a common symptom of open-angle glaucoma, but rather an indication of acute angle closure glaucoma, which is a medical emergency that requires immediate treatment. The nurse should instruct the client to apply the medication as prescribed, regardless of pain level, and seek medical attention if they experience severe eye pain, headache, nausea, or blurred vision.
Choice B reason: This is incorrect because using the medication only until the intraocular pressure returns to normal can cause recurrence or worsening of open-angle glaucoma. Intraocular pressure is the pressure inside
the eye that can affect eye health and vision. Normal intraocular pressure ranges from 10 to 21 mmHg, but it can vary depending on age, time of day, or other factors. The nurse should instruct the client to monitor their intraocular pressure regularly and report any changes to their provider, but not to stop using
the medication without consulting their provider first.
Choice C reason: This is incorrect because using the medication for approximately 10 days, then gradually tapering off can cause rebound or adverse effects of open-angle glaucoma. The medication for open-angle glaucoma can be either beta-blockers, such as timolol, or cholinergic agents, such as pilocarpine, which work by reducing fluid production or increasing fluid drainage in the eye. The nurse should instruct the client to follow their provider's instructions on how long and how much to use the medication and not to change or discontinue it abruptly without their provider's approval.
Choice D reason: This is correct because applying the medication on a regular schedule for the rest of your life can help control and prevent the progression of open-angle glaucoma. Open-angle glaucoma is a lifelong condition that requires consistent and continuous treatment to maintain normal intraocular pressure and prevent vision loss. The nurse should instruct the client to apply the medication at the same time every day and not to miss or skip any doses. The nurse should also teach the client how to store, handle, and administer the medication properly and safely.
