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 ["35"]
Explanation
Step 1 is: To find out how many mL/hr the nurse should set the infusion pump to deliver, we need to divide the total volume of enteral nutrition (840 mL) by the total time (24 hours).
So, the calculation is: 840 mL ÷ 24 hours = 35 mL/hr Therefore, the nurse should set the infusion pump to deliver 35 mL/hr.
Correct Answer is B
Explanation
Choice A rationale
Excessive thirst and urination are symptoms of hyperglycemia, not hypoglycemia. Hyperglycemia could occur if the TPN solution was infusing too quickly, but it would not be a result of the infusion pump not working.
Choice B rationale
Shakiness and diaphoresis are manifestations of hypoglycemia. When a sudden interruption in the infusion of TPN occurs, the patient is at risk for hypoglycemia.
Choice C rationale
Fever and chills are symptoms of infection, not a direct result of the TPN infusion stopping.
Choice D rationale
Hypertension and crackles in the lungs are signs of fluid overload, not hypoglycemia. These symptoms would not be expected if the TPN infusion stopped.
