A nurse finds that the infusion pump for a patient’s total parenteral nutrition (TPN) solution is not working. What condition should the nurse monitor the patient for?
Excessive thirst and urination.
Shakiness and diaphoresis.
Fever and chills.
Hypertension and crackles.
The Correct Answer is B
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.

Correct Answer is B
Explanation
Choice A rationale
0.9% sodium chloride, also known as normal saline, is an isotonic solution that is commonly used for hydration and to replace lost fluids. However, it does not provide any calories or nutrients, which are necessary for patients receiving TPN1.
Choice B rationale
Dextrose 10% in water (D10W) is the recommended solution to administer until the next TPN solution is available. This is a hypertonic fluid that provides dextrose to the patient, helping to maintain their blood glucose levels and reducing the risk of hypoglycemia.
Choice C rationale
3% sodium chloride is a hypertonic saline solution that is typically used to treat patients with severe hyponatremia (low sodium levels). It is not suitable as a replacement for TPN as it does not provide the necessary nutrients and can lead to hypernatremia (high sodium levels) if used inappropriately.
Choice D rationale
Lactated Ringer’s solution is an isotonic solution that is commonly used for fluid resuscitation in patients with significant fluid loss. While it does contain multiple electrolytes that mimic those found in plasma, it does not provide any calories or nutrients, making it unsuitable as a replacement for TPN1.
Correct Answer is D
Explanation
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.
