Final answer:
Pediatric patients have little subcutaneous fat which affects their ability to move in the blood stream. They also have higher energy requirements and are often underweight.
Step-by-step explanation:
In comparison to adults, pediatric patients have little subcutaneous fat and therefore they cannot move easily in the blood stream because they are fat based, while the blood is water based. Additionally, pediatric patients have a higher energy requirement, so they are often underweight and may have other nutritional deficiencies as well.
