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?
Amsler grid.
Snellen chart.
Intraocular pressure.
Refraction test.
The Correct Answer is A
Choice A reason: This is the correct answer because the Amsler grid test is performed to diagnose macular degeneration. The Amsler grid is a pattern of straight lines with a dot in the center. The client is asked to look at the dot and report any distortions or missing areas in the grid. This can indicate damage to the macula, which is the central part of the retina that provides sharp vision.
Choice B reason: This is incorrect because the Snellen chart test is not performed to diagnose macular degeneration. The Snellen chart is a chart of letters of different sizes that are read from a distance. The client is asked to read the smallest line they can see clearly. This can indicate visual acuity or sharpness of vision, but not macular degeneration.
Choice C reason: This is incorrect because the intraocular pressure test is not performed to diagnose macular degeneration. The intraocular pressure test measures the pressure inside the eye using a device called a tonometer. The client may feel a puff of air or a gentle touch on their eye. This can indicate glaucoma, which is a condition where increased pressure damages the optic nerve, but not macular degeneration.
Choice D reason: This is incorrect because the refraction test is not performed to diagnose macular degeneration. The refraction test measures how well the eye bends light rays using a device called a phoropter. The client looks through different lenses and reports which ones make their vision clearer. This can indicate refractive errors such as nearsightedness, farsightedness, or astigmatism, but not macular degeneration.

Correct Answer is D
Explanation
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.
Correct Answer is ["C","E","F"]
Explanation
Choice A reason: This is incorrect because the nurse should not include this in the postoperative education to the client. The client should not drive home after glaucoma surgery, as they will have reduced vision and increased sensitivity to light in the operated eye. The nurse should advise the client to arrange for someone else to drive them home.
Choice B reason: This is incorrect because the nurse should not include this in the postoperative education to the client. The client should not lie on the right side when going to bed, as this can put pressure on the operated eye and increase the risk of bleeding or infection. The nurse should advise the client to sleep on their back or on their left side.
Choice C reason: This is correct because the nurse should include this in the postoperative education to
the client. The client should report flashing lights, as this can indicate a complication such as retinal detachment or vitreous hemorrhage. The nurse should instruct the client to call the provider immediately if they see flashing lights.
Choice D reason: This is incorrect because the nurse should not include this in the postoperative education to the client. The client should not nap on their left side when they get home, as this can cause fluid accumulation and increased intraocular pressure in the operated eye. The nurse should advise the client to elevate their head at least 30 degrees when resting.
Choice E reason: This is correct because the nurse should include this in the postoperative education to
the client. The client should avoid housework like vacuuming, as this can cause bending, lifting, or straining that can increase intraocular pressure and affect wound healing. The nurse should advise the client to limit physical activity and follow the provider's instructions on when to resume normal activities.
Choice F reason: This is correct because the nurse should include this in the postoperative education to
the client. The client may see flashes of light in the operated eye, as this is a normal phenomenon caused by stimulation of the retina by gas bubbles or fluid shifts. The nurse should reassure the client that flashes of light are normal and will subside over time.
