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 portal hypertension means that there is high blood pressure in the portal vein, which carries blood from the digestive organs to the liver. When the liver is damaged by hepatitis, it becomes scarred and obstructs the blood flow, causing increased pressure in the portal vein. This leads to fluid accumulation in the abdomen, called ascites, which causes abdominal swelling.
Choice B reason: This is incorrect because portal hypertension is not caused by the heart overworking but by liver damage. The heart does not pump blood into the portal vein, but into the hepatic artery, which supplies oxygenated blood to the liver.
Choice C reason: This is incorrect because portal hypertension does not develop when cirrhosis begins to resolve, but when it progresses. Cirrhosis is a chronic condition that causes irreversible scarring of the liver tissue, which worsens over time and increases portal hypertension.
Choice D reason: This is incorrect because eating high-sodium foods and a stressful lifestyle do not cause portal hypertension, but they can aggravate it. High-sodium foods can increase fluid retention and worsen ascites, while stress can increase blood pressure and worsen bleeding complications. The nurse should advise the client to limit sodium intake and manage stress levels.
Correct Answer is B
Explanation
Choice A Reason: The test is not inconclusive, but rather positive for conductive hearing loss. The Weber test involves placing a vibrating tuning fork on the center of the forehead and asking the client which ear hears the sound louder. It can help differentiate between conductive and sensorineural hearing loss.
Choice B Reason: This is the correct choice. The client has conductive hearing loss, which is a type of hearing loss that occurs when sound waves are blocked or reduced in the outer or middle ear. It can be caused by earwax, infection, fluid, perforation, or trauma. In conductive hearing loss, the Weber test shows lateralization to the affected ear, meaning the sound is heard louder in that ear.
Choice C Reason: The client does not have normal hearing, but rather conductive hearing loss. In normal hearing, the Weber test shows no lateralization, meaning the sound is heard equally in both ears.
Choice D Reason: The client does not have sensorineural hearing loss, but rather conductive hearing loss. Sensorineural hearing loss is a type of hearing loss that occurs when there is damage to the inner ear or auditory nerve. It can be caused by aging, noise exposure, disease, or drugs. In sensorineural hearing loss, the Weber test shows lateralization to the unaffected ear, meaning the sound is heard louder in that ear.
