Which client is at highest risk for developing dehydration and hypernatremia as a result of enteral feedings?
a. Client receiving an isotonic enteral feeding solution and an IV of D5W (dextrose 5% in water) at 83 mL/hr
b. Client receiving a hypertonic enteral feeding solution and an IV of normal sa-line (0.9 NS) at 125 mL/hr
c. Client who can drink liquids and is re-ceiving a supplemental hypertonic enteral feeding solution
d. Client receiving a hypertonic enteral feeding solution and an IV of 0.45% NS (0.45 NS) infusing at 125 mL/hr
B
Hypertonic enteral tube feedings can easily lead to dehydration and hypernatremia if not ba-lanced with hypotonic IV solution. D5W and 0.45 NS are hypotonic solutions. A client with hypertonic feedings who can drink liquids should have enough oral fluid intake to prevent dehy-dration and hypernatremia. The client receiving both a hypertonic enteral feeding and an isotonic IV solution would be at highest risk.
