What is the preferred energy dose for patients receiving parenteral nutrition?

15-20 kcal/kg/day
20-25 kcal/kg/day
25-30 kcal/kg/day
30-35 kcal/kg/day

The correct answer is: 20-25 kcal/kg/day

For patients receiving parenteral nutrition, the preferred energy dose is typically 20-25 kcal/kg/day. This range is generally considered adequate to meet the energy needs of most patients while minimizing the risks associated with overfeeding, such as hyperglycemia, fatty liver, and other complications. When calculating the energy requirements for patients on parenteral nutrition, it's important to take into account factors such as the patient's age, weight, activity level, and any underlying medical conditions. The 20-25 kcal/kg/day range is a balanced approach that allows for sufficient caloric intake to promote healing and maintain metabolic health without overwhelming the patient's system. In contrast, lower energy doses, like those below this range, might not provide enough caloric support for patients who are in a catabolic state or have increased energy needs. On the other hand, higher doses can lead to complications and should typically be reserved for specific situations where increased caloric intake is necessary and monitored closely. Therefore, the range of 20-25 kcal/kg/day represents a safe and effective guideline for managing energy intake in patients receiving parenteral nutrition.
