Question 1

Which enteral formula type is most appropriate for a patient with fat malabsorption requiring a high proportion of medium-chain triglycerides?

Accepted Answer

Semi-elemental formula

Semi-elemental formulas contain medium-chain triglycerides and partially hydrolyzed proteins that are better absorbed in patients with fat malabsorption.

Question 2

What is the primary indication for initiating parenteral nutrition (PN) in a hospitalized patient?

Accepted Answer

Non-functional or inaccessible GI tract for more than 7 days

Answer

PN is indicated when the GI tract is non-functional, inaccessible, or cannot meet nutritional needs enterally for an extended period.

Question 3

A patient on total parenteral nutrition (TPN) develops hyperglycemia. What is the first recommended intervention?

Accepted Answer

Reduce dextrose concentration and initiate insulin protocol

Answer

Reducing dextrose content and starting an insulin protocol is the standard first-line management for TPN-associated hyperglycemia.

Question 4

Which access route is preferred for long-term enteral nutrition in a patient with a functional stomach?

Accepted Answer

Percutaneous endoscopic gastrostomy (PEG)

Answer

A PEG tube is preferred for long-term enteral feeding (>4 weeks) in patients with a functional stomach as it is more comfortable and stable.

Question 5

Refeeding syndrome in a malnourished patient initiating PN is primarily caused by a shift in which electrolyte?
