Q: Consider following statements in respect of parenteral nutrition : 1. indicated in patients when enteral nutrition cannot be given 2. parenteral route is a better choice than enteral route 3. abnormalities of liver functions can occur on prolonged use 4. hyperglycemia is common Which of the above statements are correct ?

1, 3 and 4 only. ***1, 3 and 4 only*** - **Parenteral nutrition (PN)** is used when the gastrointestinal tract is non-functional or inaccessible, making **enteral nutrition (EN)** impossible or inadequate. - **Hyperglycemia** is a common complication due to the high glucose content in PN solutions, and **liver function abnormalities** (e.g., cholestasis, steatosis) can develop with prolonged use. *2, 3 and 4 only* - This option incorrectly states that the parenteral route is better than the enteral route. **Enteral nutrition** is generally preferred due to being more physiological, safer, and less expensive [1]. - While hyperglycemia and liver dysfunction are correct complications, the assertion about the superiority of the parenteral route is false. *1, 2 and 3 only* - This option incorrectly claims that **parenteral nutrition** is a better choice than the enteral route (statement 2). **Enteral nutrition** is always the preferred route if the gut works [1]. - It also omits **hyperglycemia**, which is a frequent and significant complication of parenteral nutrition. *1, 2, 3 and 4* - This option incorrectly includes statement 2, which suggests the parenteral route is superior to the enteral route. **Enteral nutrition** is always preferred when feasible [1]. - While statements 1, 3, and 4 are correct, the inclusion of statement 2 makes this option incorrect.
