Question

Quizplus · Accepted Answer

The decision to start parenteral nutrition should consider the length of time nutrition support is needed, as it is a highly invasive and expensive form of nutrition support that should only be considered when all other options have been exhausted or deemed inadequate for meeting the patient's nutritional needs. Other factors such as the patient's BMI, need for amino acids, the physician's ability to obtain an order, and the need for an automated compounder may also need to be considered but are not as critical as the length of time nutrition support is needed.
