Which statement explains why early enteral feeding might be delayed in critically ill patients?

• A. To avoid risk of intestinal ischemia before stability
• B. To prevent overheating
• C. To avoid protein deficiency
• D. To prevent electrolyte imbalance

Answer: (A)

The key idea is that in critically ill patients, gut blood flow is fragile and can be greatly affected by shock or vasopressors. Starting enteral feeding before the patient is hemodynamically stable increases the gut’s metabolic demand when its perfusion is compromised, raising the risk of intestinal ischemia or severe feeding intolerance. Waiting until stabilization reduces this risk and allows the gut to tolerate nutrition more safely, after which feeding can be advanced gradually. Other options aren’t as central to the timing issue. Overheating isn’t a primary concern driving when to start EN. Protein deficiency is better addressed by ensuring adequate nutrition, which early feeding can help prevent rather than delay. Electrolyte imbalance can occur with feeding, but it’s managed with monitoring and adjustments rather than being the main reason to delay initiation.
