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 C
Explanation
Choice A Reason: Obtaining the client's blood glucose every 12 hr is not enough, as the nurse should monitor it more frequently, at least every 4 to 6 hr, to prevent hyperglycemia or hypoglycemia. TPN is a high-glucose solution that can affect the blood sugar levels.
Choice B Reason: Changing the IV site dressing every 4 days is not enough, as the nurse should change it daily or as needed to prevent infection. TPN is a high-risk solution that can introduce microorganisms into the bloodstream.
Choice C Reason: This is the correct choice. Changing the IV tubing every 24 hr is recommended to prevent infection and maintain sterility. TPN is a complex solution that can support bacterial growth and contamination.
Choice D Reason: Weighing the client every other day is not enough, as the nurse should weigh the client daily to evaluate fluid balance and nutritional status. TPN can cause fluid retention or depletion, as well as weight gain or loss.
Correct Answer is A
Explanation
Choice A reason: This is the correct answer because this describes a stupor, which is a state of near-unconsciousness or reduced responsiveness. A stuporous client shows minimal movement and verbal responses and requires extreme vigorous stimulation such as painful stimuli to awaken briefly.
Choice B reason: This is incorrect because this describes obtundation, which is a state of reduced alertness or awareness. An obtunded client is extremely drowsy and minimally responsive and requires vigorous stimulation such as shaking or shouting to wake.
Choice C reason: This is incorrect because this describes lethargy, which is a state of decreased energy or activity. A lethargic client is alert and oriented x3 (to person, place, and time), but sluggish and drowsy, and wakes to voice or gentle shaking.
Choice D reason: This is incorrect because this describes a coma, which is a state of deep unconsciousness or unresponsiveness. A comatose client does not respond to verbal stimuli or speak and shows abnormal posturing in response to pain, such as decorticate (flexion of arms and extension of legs) or decerebrate (extension of arms and legs).
