NURSING PHARMACOLOGY NCLEX MASTERY EXAM QUIZ 1 50 Q&A’S WITH RATIONALES LATEST
1. A 2-year-old child is receiving temporary total parenteral nutrition (TPN) through a central
venous line. This is the first day of TPN therapy. Although all of the following nursing actions
must be included in the plan of care of this child, which one would be a priority at this time?
o A. Use aseptic technique during dressing changes.
o B. Maintain central line catheter integrity.
o C. Monitor serum glucose levels.
o D. Check results of liver function tests.
Correct Answer: C. Monitor serum glucose levels
Monitor serum glucose levels. Hyperglycemia may occur during the first day or 2 as the child
adapts to the high-glucose load of the TPN solution. Thus, a chief nursing responsibility is blood
glucose testing. Total parenteral nutrition (TPN), also known as parenteral nutrition (PN) is a
form of nutritional support given completely via the bloodstream, intravenously with an IV
pump. TPN administers proteins, carbohydrates, fats, vitamins, and minerals. It aims to prevent
and restore nutritional deficits, allowing bowel rest while supplying adequate caloric intake and
essential nutrients, and removing antigenic mucosal stimuli (Perry et al., 2014).
 Option A: With proper care, a central catheter can be maintained for several days
or even weeks for the delivery of TPN. Apply strict aseptic technique during
insertion, care, and maintenance. Frequently assess the CVC site for redness,
tenderness, or drainage. Notify the health care provider of any signs and
symptoms of infection.
 Option B: Strict asepsis is to be observed during the placement of the catheter. A
chest radiograph should be taken prior to the commencement of feeding to
confirm the position of the catheter-tip and to exclude traumatic pneumothorax,
the commonest complication related to catheter placement.
