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 ["A","B","C","D"]
Explanation
Choice A Reason: A distended bladder is one of the most common triggers of autonomic dysreflexia, which is a life-threatening condition that occurs in clients with spinal cord injuries above T-6. The bladder becomes overfilled and stimulates the sympathetic nervous system, causing vasoconstriction and hypertension.
Choice B Reason: A severe headache is one of the most common symptoms of autonomic dysreflexia, caused by the increased blood pressure in the brain. The headache may be accompanied by blurred vision, sweating, flushing, or anxiety.
Choice C Reason: An elevated blood pressure is the hallmark sign of autonomic dysreflexia, which can reach dangerously high levels and cause stroke, seizure, or death. The blood pressure may rise up to 300/160 mmHg or higher.
Choice D Reason: Nasal congestion is another possible trigger of autonomic dysreflexia, as it stimulates the nasal mucosa and activates the sympathetic nervous system. Other potential triggers include bowel impaction, skin irritation, tight clothing, or temperature changes.
Correct Answer is A
Explanation
Choice A Reason: This is the correct choice. Washing towels, sheets, and pillowcases is a home care instruction that the nurse will offer to the client, as it prevents reinfection and transmission of bacteria or viruses. The client has conjunctivitis, which is inflammation of the conjunctiva or thin membrane that covers the white part of the eye and lines the eyelids. It can be caused by bacteria, viruses, allergies, or irritants.
Choice B Reason: This is an incorrect choice. Using antifungal drops 3 times a day is not a home care instruction that the nurse will offer to the client, as it is not effective for conjunctivitis. Antifungal drops are used for fungal infections of the eye, which are rare and usually occur after trauma or surgery. The client may need antibiotic or antiviral drops, depending on the cause of conjunctivitis.
Choice C Reason: This is an incorrect choice. Scheduling a sexually transmitted infection (STI/STD) exam is not a home care instruction that the nurse will offer to the client, as it is not relevant for conjunctivitis. STIs can affect the eyes, but they usually cause different symptoms, such as redness, pain, or discharge from the urethra or vagina. The client may need to be tested for STIs if they have other risk factors or signs of infection.
Choice D Reason: This is an incorrect choice. Avoiding going outside during daylight hours is not a home care instruction that the nurse will offer to the client, as it is not necessary for conjunctivitis. The client may experience sensitivity to light, but they can wear sunglasses or avoid direct sunlight to protect their eyes. The client should also avoid rubbing or touching their eyes, wear glasses instead of contact lenses, and discard any eye makeup or cosmetics that may be contaminated.
