In the context of PN, what does "feeding intolerance" commonly refer to?

Feeding intolerance is a term often used in the context of parenteral nutrition (PN) and related feeding methods, particularly regarding enteral feeds, which involve nutrition provided directly to the gastrointestinal tract. The most common interpretation of feeding intolerance focuses on adverse reactions to enteral feeds. This can include symptoms such as abdominal distension, diarrhea, nausea, vomiting, or increased gastric residuals, all indicating that the digestive system is not handling the provided nutrition well.

These adverse reactions can occur due to various factors, such as the composition of the formula, the rate of feeding, the underlying health and functioning of the gastrointestinal tract, or how well the practice of feeding fits with the individual patient’s needs. Monitoring for and understanding feeding intolerance is critical to ensure proper nutrition and to make adjustments to the feeding regimen that can help alleviate these issues.

The other options do not accurately capture the specific context of feeding intolerance as it applies to enteral feeds—option A describes a general inability to consume food, option C specifies a particular dietary component and its digestion, and option D involves a behavioral aspect of food consumption, neither of which address the specific concept of adverse reactions seen with enteral feedings. So, the focus on adverse reactions makes the chosen response fitting in
