Answer to Question 1

ANS: D
During central venous catheter 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.

Answer to Question 2

ANS: A
Signs and symptoms of hyperglycemia are thirst, headache, lethargy, and increased urination. Hypocapnia is not associated with parenteral nutrition. Hypercapnia increases oxygen consumption and increases CO2 levels. Ventilator-dependent patients are at greatest risk for this. Hypoglycemia is characterized by diaphoresis, shakiness, confusion, and loss of consciousness.
