The physiological rationale for hanging normal saline (0.9% NS) or 5% dextrose in water (D5W) to a client who has been experiencing diarrhea includes:
A) Facilitating the absorption of osmotically active particles
B) Activation of the ATP channels
C) Activating the pancreatic enzymes of trypsin and elastase
D) Emulsification of fats
Ans: A
Feedback:
Water absorption from the intestine is linked to absorption of osmotically active particles, such as glucose and sodium. It follows that an important consideration in facilitating the transport of water across the intestine (and decreasing diarrhea) after temporary disruption in bowel function is to include sodium and glucose in the fluids that are consumed. None of the other distractors addresses this principle. Activating the pancreatic enzymes of trypsin and elastase is needed for protein digestion and absorption. Emulsification of fats begins in the stomach and continues in the duodenum under the influence of bile from the liver.
