Answer to Question 1

ANS: C
Sudden discontinuation of PN can cause hypoglycemia. PN must be tapered off. Usually, 10 dextrose is infused when PN solution is suddenly discontinued. The same is true if the PN runs out. Too rapid administration of hypertonic dextrose (PN) can result in an osmotic diuresis and dehydration. If an infusion falls behind schedule, the nurse should not increase the rate in an at-tempt to catch up.

Answer to Question 2

ANS: C
During CVC dressing changes, always use a sterile mask and gloves, and assess insertion sites for signs and symptoms of infection. To avoid infection, change the TPN infusion tubing every 24 hours, and do not hang a single container of PN for longer than 24 hours or lipids longer than 12 hours.
