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 D
Explanation
Choice A Reason: This is incorrect because intestinal obstruction is not a common complication of ileostomy surgery. An ileostomy is a surgical opening in the abdomen that connects the end of the small intestine (ileum) to a pouch or bag outside the body. This allows stool to bypass the colon and rectum. Intestinal obstruction can occur if there is a blockage or narrowing in any part of the digestive tract, but it is more likely to affect the colon than the ileum.
Choice B Reason: This is incorrect because folate deficiency is not a common complication of ileostomy surgery. Folate is a vitamin that is essential for DNA synthesis and cell division. Folate is mainly absorbed in the jejunum, which is the middle part of the small intestine. An ileostomy does not affect the jejunum, so it does not interfere with folate absorption.
Choice C Reason: This is incorrect because malabsorption of fat is not a common complication of ileostomy surgery. Fat is digested and absorbed in both the small and large intestine. An ileostomy does not affect fat digestion, but it may reduce fat absorption by decreasing the transit time and surface area of the intestine. However, this is usually not significant enough to cause malabsorption symptoms.
Choice D Reason: This is correct because fluid and electrolyte imbalance is a common complication of ileostomy surgery. Fluid and electrolytes are mainly absorbed in the colon, which is bypassed by an ileostomy. This can result in increased fluid and electrolyte loss through stool, especially sodium and potassium. This can lead to dehydration, hypotension, weakness, cramps, or arrhythmias.
Correct Answer is ["B","E","F"]
Explanation
Choice A Reason: Edema is not a specific finding of a systemic infection, but rather a possible sign of fluid overload or impaired venous return. It can occur due to excessive infusion rate, heart failure, or obstruction of blood flow in or around the central line.
Choice B Reason: This is a correct choice. Purulent drainage at intravenous insertion site is a finding of a local infection that can spread systemically. It indicates bacterial invasion and inflammation of the skin and subcutaneous tissue around the catheter.
Choice C Reason: Redness at insertion site is a finding of a local infection that can spread systemically. It indicates increased blood flow and inflammation of the skin and subcutaneous tissue around the catheter.
Choice D Reason: Nausea is not a specific finding of a systemic infection, but rather a possible side effect of parenteral nutrition or a symptom of another condition. It can occur due to electrolyte imbalance, hyperglycemia, or gastrointestinal disorders.
Choice E Reason: This is a correct choice. Leukocytosis is a finding of a systemic infection that indicates increased production and release of white blood cells in response to infection. It can be detected by a blood test.
Choice F Reason: This is a correct choice. Fever is a finding of a systemic infection that indicates increased body temperature due to activation of the immune system and release of pyrogens. It can be measured by a thermometer.
