Chapter 55 : Nutritional Supplements Questions
Question 1 of 5
A woman has been receiving both radiation and chemotherapy for her cancer. Lately, she has developed anorexia caused by the treatments, so she needs short-term nutrition supplementation. The nurse anticipates that the physician will initiate which therapy?
Correct Answer: B
Rationale: Peripheral parenteral nutrition is indicated for anorexia caused by radiation or cancer chemotherapy.
Total parenteral nutrition is indicated for more long-term use. The other options are incorrect.
Question 2 of 5
During the night shift, a patient's total parenteral nutrition (TPN) infusion ran out, and the nurse discovered that there was no TPN solution on hand to continue the infusion. The pharmacy is closed and will not reopen for 5 hours. The nurse will have to implement measures to prevent which consequence of abruptly discontinuing TPN infusions?
Correct Answer: D
Rationale: Rebound hypoglycemia may occur if TPN is discontinued abruptly. It may be prevented by infusion of 5% to 10% glucose in situations in which TPN must be stopped abruptly. The other options are incorrect.
Question 3 of 5
When monitoring a patient who has been receiving peripheral parenteral nutrition for more than 3 weeks, the nurse will watch for which potential complication?
Correct Answer: B
Rationale: The long-term administration of nutritional supplements via a peripheral vein may lead to phlebitis and, possibly, the loss of a limb.
Question 4 of 5
A patient has been receiving total parenteral nutrition. Upon assessment, the nurse notes these assessment findings: blood pressure 160/98 mm Hg (elevated from previous readings); pulse rate 110 beats/min and weak; pitting edema on both ankles; and new-onset confusion. The nurse suspects that the patient is experiencing which condition?
Correct Answer: D
Rationale: Fluid overload may occur with parenteral nutrition. It is manifested by weak pulse, hypertension, tachycardia, confusion, decreased urine output, and pitting edema.
Question 5 of 5
The peripheral parenteral nutrition bag that has been infusing into the patient is empty, and the nurse realizes that the next bag is not ready. The nurse should immediately hang which of these intravenous solutions until the new bag arrives?
Correct Answer: A
Rationale: If intravenous parenteral nutrition is discontinued abruptly, rebound hypoglycemia may occur. This can be prevented with infusion of 5% to 10% glucose until the parenteral nutrition infusion is ready. For peripheral infusions, the dextrose must not be more than 10%.
