What precautions are necessary when re-nourishing a malnourished patient?

• A. Refeed gradually, monitor for refeeding syndrome (electrolyte shifts), and adjust caloric intake with close supervision.
• B. Refeed rapidly, increasing calories quickly without monitoring.
• C. Start with high sugar beverages only.
• D. Avoid electrolyte monitoring.

Answer: (A)

Refeeding malnourished patients must be done cautiously to prevent refeeding syndrome, a dangerous shift in fluids and electrolytes that can happen when nutrition is reintroduced too quickly. The body of someone who is severely malnourished adapts to low insulin levels; when calories are suddenly given, insulin rises and drives phosphate, potassium, and magnesium into cells. This can lead to life-threatening problems like arrhythmias, respiratory failure, edema, weakness, and organ dysfunction.

That’s why the best approach is to refeed gradually with close supervision and to tailor caloric increases to the patient’s response. Start with a low caloric intake and advance slowly while monitoring electrolytes (phosphate, potassium, magnesium), fluid balance, weight, vital signs, and clinical signs of intolerance. Provide thiamine and other micronutrients before and during feeding to prevent deficiency-related complications. If electrolyte abnormalities are present, correct them carefully as feeding proceeds.

In contrast, rapidly increasing calories without monitoring, starting with only high-sugar fluids, or skipping electrolyte checks can precipitate refeeding syndrome and serious complications.
