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 B
Explanation
Choice A reason: This is incorrect because preparing the client for an X-ray is not the first action that the nurse should take. An X-ray can help diagnose possible injuries or fractures, but it is not an urgent test. The nurse should first assess the client's level of consciousness and neurological status using a standardized tool such as the Glasgow Coma Scale.
Choice B reason: This is the correct answer because calculating a Glasgow Coma Score is the first action that the nurse should take. The Glasgow Coma Scale is a tool that measures the level of consciousness based on the eye-opening, verbal response, and motor responses. It can help determine the severity of brain injury and guide further interventions.
Choice C reason: This is incorrect because dimming the lights and turning off the TV are not the first actions that the nurse should take. These are environmental modifications that can help reduce sensory stimulation and prevent agitation or seizures, but they are not as important as assessing the level of consciousness and neurological status.
Choice D reason: This is incorrect because providing analgesics is not the first action that the nurse should take. Analgesics can help relieve pain and discomfort, but they can also alter the level of consciousness and mask neurological signs. The nurse should first assess the level of consciousness and neurological status, and then administer analgesics as prescribed.
Correct Answer is A
Explanation
Choice A Reason: This is correct because first degree burns are superficial burns that affect only the outer layer of the skin, called the epidermis. First degree burns cause redness, pain, and mild swelling, but no blisters or scarring. They usually heal within a week.
Choice B Reason: This is incorrect because second degree burns are partial thickness burns that affect both the epidermis and the underlying layer of the skin, called the dermis. Second degree burns cause blisters, severe pain, and possible infection. They may take several weeks to heal and may leave scars.
Choice C Reason: This is incorrect because third degree burns are full thickness burns that destroy all layers of the skin and may damage the underlying tissues, such as muscles, nerves, or bones. Third degree burns cause charred or white skin, numbness, and shock. They require skin grafting and may cause permanent disability or death.
Choice D Reason: This is incorrect because this burn can be classified according to the depth and extent of the skin damage. The classification of burns helps to determine the appropriate treatment and prognosis for the client.
