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","B","C","D","E"]
Explanation
Choice A Reason: This is correct because clinical obesity is a risk factor for metabolic syndrome. Clinical obesity is defined by having a body mass index (BMI) of 30 or higher, or a waist circumference of more than 40 inches for men or 35 inches for women. Obesity can increase insulin resistance and inflammation, which can lead to metabolic syndrome.
Choice B Reason: This is correct because elevated blood pressure is a risk factor for metabolic syndrome. Elevated blood pressure is defined by having a systolic blood pressure of 130 mm Hg or higher, or a diastolic blood pressure of 85 mm Hg or higher. High blood pressure can damage the blood vessels and increase the risk of cardiovascular disease, which is associated with metabolic syndrome.
Choice C Reason: This is correct because high triglycerides are a risk factor for metabolic syndrome. Triglycerides are a type of fat that circulates in the blood and provides energy for the cells. High triglycerides are defined by having a level of 150 mg/dL or higher. High triglycerides can increase the risk of fatty liver disease and pancreatitis, which are related to metabolic syndrome.
Choice D Reason: This is correct because hypercholesterolemia is a risk factor for metabolic syndrome. Hypercholesterolemia is defined by having a total cholesterol level of 200 mg/dL or higher, or a low-density lipoprotein (LDL) cholesterol level of 100 mg/dL or higher. LDL cholesterol is also known as "bad" cholesterol because it can build up in the arteries and cause plaque formation and narrowing, which can lead to cardiovascular disease and metabolic syndrome.
Choice E Reason: This is correct because hyperglycemia is a risk factor for metabolic syndrome. Hyperglycemia is defined by having a fasting blood glucose level of 100 mg/dL or higher, or a hemoglobin A1c level of 5.7% or higher. Hemoglobin A1c is a measure of average blood glucose over three months. Hyperglycemia can indicate impaired glucose metabolism and insulin resistance, which are hallmarks of metabolic syndrome.
Correct Answer is C
Explanation
Choice A Reason: Inserting a nasal swab to observe the fluid is contraindicated, as it can introduce infection or increase intracranial pressure. The fluid can be tested for glucose or halo sign to confirm cerebrospinal fluid (CSF) leakage.
Choice B Reason: Suctioning the nose gently with a bulb syringe is also contraindicated, as it can create negative pressure and increase CSF leakage or cause meningitis.
Choice C Reason: This is the correct answer because allowing the drainage to drip onto a sterile gauze pad can prevent contamination and facilitate observation of the amount and characteristics of the fluid.
Choice D Reason: Inserting sterile packing into the nares is not recommended, as it can obstruct the drainage and increase intracranial pressure or infection risk.
