Parenteral Nutrition Statements Evaluation
This section evaluates the correctness of statements regarding parenteral nutrition (PN).
- Statement 1: Indication
Parenteral nutrition is medically indicated when a patient cannot receive adequate nutrition via the gastrointestinal tract (enteral route). This makes the statement correct. - Statement 2: Route Preference
The enteral route is preferred over the parenteral route whenever feasible because it preserves gut integrity and is associated with fewer complications. PN is a secondary option used only when EN is not possible. This statement is incorrect. - Statement 3: Liver Function
Prolonged use of parenteral nutrition can lead to complications such as liver function abnormalities, including cholestasis and steatosis. This statement is correct. - Statement 4: Hyperglycemia
Parenteral nutrition solutions typically contain concentrated dextrose, which can commonly cause hyperglycemia, particularly in patients with diabetes or metabolic stress. This statement is correct.
Conclusion on Correct Statements
Based on the analysis, statements 1, 3, and 4 accurately describe aspects of parenteral nutrition. Statement 2 incorrectly suggests PN is a better choice than EN.
Therefore, the correct combination of statements is 1, 3, and 4.
