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.

Answer and Explanation

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 ["2600"]

Explanation

The total fluid prescribed is 5,200 mL over 24 hours. We need to calculate how much fluid the client will receive in the first 8 hours.

Step-by-Step Calculation:

Step 1: Determine how much fluid is given in the first 8 hours. The rule is that half of the total fluid is administered in the first 8 hours.

Total fluid = 5,200 mL.
Fluid for the first 8 hours = Total fluid ÷ 2.

Write it out:
5,200 ÷ 2 = 2,600.

Result: 2,600 mL.

A. Atrial fibrillation. B. Hypertension. C. Diabetes. D. Alcohol abuse.

Correct Answer is A

Explanation

Choice A reason: This is the correct answer because atrial fibrillation is the risk factor that puts the client at
the highest risk for embolic stroke. Atrial fibrillation is an irregular and rapid heart rate that causes poor blood flow and blood pooling in the heart chambers. This can lead to the formation of blood clots that can travel to the brain and block an artery, causing an embolic stroke.

Choice B reason: This is incorrect because hypertension is not the risk factor that puts the client at
the highest risk for embolic stroke. Hypertension is high blood pressure that puts stress on the blood vessels and increases the risk of bleeding or rupture. This can lead to a hemorrhagic stroke, but not an embolic stroke.

Choice C reason: This is incorrect because diabetes is not the risk factor that puts the client at
the highest risk for embolic stroke. Diabetes is a condition that causes high blood sugar levels and damages the blood vessels and nerves. This can lead to poor circulation and increased risk of infection and ulcers, but not an embolic stroke.

Choice D reason: This is incorrect because alcohol abuse is not the risk factor that puts the client at
the highest risk for embolic stroke. Alcohol abuse is excessive consumption of alcohol that affects liver function and blood clotting factors. This can lead to liver disease and bleeding disorders, but not an embolic stroke.
