Fundamentals of Nursing Q 253
A nurse is preparing to hang the initial bag of the parenteral nutrition (PN) solution via the central line of a malnourished client. The nurse ensures the availability of which medical equipment before hanging the solution?
A. Glucometer.
B. Dressing tray.
C. Nebulizer.
D. Infusion pump.
Correct Answer: D. Infusion pump.
The nurse should prepare an infusion pump prior to hanging a parenteral solution. The use of an infusion pump is important to make sure that the solution does not infuse too quickly or delayed since the parenteral nutrition has a high glucose content. An infusion pump controls the rate at which the TPN solution is given so that the concentrated food does not overload other digestive organs. For many patients receiving TPN, the pump is portable.
Option A: A glucometer is also needed since the client’s glucose level is monitored every 4 to 6 hours, but it is not an essential item needed. Hyperglycemia is associated with increased hospital complications and mortality in patients receiving TPN. TPN-induced hyperglycemia is associated with increased length of hospital stay, increased risk of complications, and higher mortality in hospitalized patients.
Option B: A dressing tray is not used before hanging a PN solution. With total parenteral nutrition, a solution of essential nutrients (including proteins, fluids, electrolytes, and fat-soluble vitamins) is given into the veins (intravenously). Because TPN solutions are highly concentrated and thick, the solutions must be given through catheters that are placed in large central veins in the neck, chest, or groin.
Option C: A nebulizer is not used before hanging a PN solution. Total parenteral nutrition (TPN) is the standard therapy for people who have this problem. TPN can be used to treat a severe disorder that is expected to last for a relatively short time, such as intractable vomiting during pregnancy. It is also used as a long-term therapy.
