Question of the day

Once electrolytes are restored to the normal range, enteral nutrition should start at what percentage of estimated energy needs and advance over 3-5 days?

Explanation:
Initiate enteral nutrition cautiously after electrolytes are normalized, using a slow ramp to support tolerance and prevent refeeding complications. Start at about 25% of estimated energy needs and increase gradually over the next 3 to 5 days to reach full energy goal. This approach helps avoid refeeding syndrome, where sudden shifts in electrolytes (like phosphate, potassium, and magnesium) can cause serious problems, and it also gives the gastrointestinal tract time to adapt. Monitor for tolerance (nausea, vomiting, distension, high gastric residuals, diarrhea) and adjust pace as needed. A typical progression is 25% on day 1, 50% on day 2, 75% on day 3, and 100% by days 4–5, depending on the patient’s tolerance.
