A nurse is caring for a patient who has a cloudy, opaque area over the lens of one eye. Which of the following visual impairments should the nurse identify this as a symptom of?
Glaucoma.
Diabetic retinopathy.
Macular degeneration.
Cataract.
The Correct Answer is D
Choice A rationale
Glaucoma is a condition that damages the eye’s optic nerve and can result in vision loss and blindness. However, it doesn’t cause a cloudy, opaque area over the lens of the eye.
Choice B rationale
Diabetic retinopathy is a diabetes complication that affects eyes. It’s caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). But it doesn’t cause a cloudy, opaque area over the lens of the eye.
Choice C rationale
Macular degeneration is a medical condition which may result in blurred or no vision in the center of the visual field. But it doesn’t cause a cloudy, opaque area over the lens of the eye.
Choice D rationale
A cataract is a clouding of the lens in the eye that affects vision. Cataracts are very common in older people. Symptoms of cataracts include cloudy or blurry vision.

Correct Answer is A
Explanation
Choice A rationale
The nurse should plan to refrigerate the urine during the collection time period. This is because the urine needs to be kept cool to prevent the breakdown of certain analytes that might be measured in the urine.
Choice B rationale
The nurse should not discard the client’s last void at the end of the collection time period. The last voided specimen should be included in the collection to ensure that the 24-hour collection is complete.
Choice C rationale
The nurse should not include toilet paper with the collected urine. Toilet paper could contaminate the urine sample and interfere with the accuracy of the test results.
Choice D rationale
The nurse should not save the first void at the start of the collection time period. The first voided specimen should be discarded, and the collection should start with the next void.
Correct Answer is B
Explanation
Choice A rationale
Troponin is a cardiac enzyme which indicates a client has experienced a myocardial infarction. It is not a laboratory test that supports a diagnosis of malnutrition.
Choice B rationale
Albumin is a measure of plasma proteins which reflects the nutritional condition of a client experiencing anorexia and malnutrition over an extended period of time. Therefore, a nurse
should expect altered albumin levels in a client who reports anorexia and is experiencing malnutrition.
Choice C rationale
Total bilirubin is altered in clients who are experiencing hepatobiliary disease. It is not a laboratory test that supports a diagnosis of malnutrition.
Choice D rationale
Creatine kinase is a cardiac enzyme which is useful in the diagnosis of a myocardial infarction. It is not a laboratory test that supports a diagnosis of malnutrition.
