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
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).
Correct Answer is B
Explanation
Choice A Reason: Antibiotics are not contraindicated for a client with glaucoma and asthma, as they can treat or prevent infections that may affect the eye or the respiratory system.
Choice B Reason: This is the correct answer because non-selective beta blockers are contraindicated for a client with glaucoma and asthma, as they can reduce intraocular pressure but also cause bronchoconstriction and exacerbate asthma symptoms.
Choice C Reason: NSAIDs are not contraindicated for a client with glaucoma and asthma, as they can reduce inflammation and pain that may affect the eye or the respiratory system.
Choice D Reason: Anticoagulants are not contraindicated for a client with glaucoma and asthma, as they can prevent or treat thromboembolic events that may affect the eye or the respiratory system.
