Final answer:
Teenagers are considered the lowest risk candidates for initiation of parenteral nutrition in the home setting compared to infants, dialysis patients, and diabetic patients due to their more stable physiological status and the lower complexity of their care requirements.
Step-by-step explanation:
The lowest risk candidates for initiation of parenteral nutrition (PN) in the home setting are teenagers. Infants may require more specialized care due to their small size and developing systems. Dialysis patients and diabetic patients have a higher risk of complications due to the presence of underlying conditions that can affect nutrition status and complicate the management of fluid and electrolytes.
For example, diabetic patients might have fluctuations in blood glucose levels that could be exacerbated by PN if not managed carefully. Similarly, dialysis patients may have fluid and electrolytes imbalances that require close monitoring. Teenagers, on the other hand, generally have more developed organ systems and are better able to tolerate the procedures and the management of PN at home.
