You would be most concerned about a TPN fat emulsion order for a client with which condition?

• A. Fractured femur
• B. Gastrointestinal obstruction
• C. Severe anorexia nervosa
• D. Chronic diarrhea and vomiting

Answer: (A)

The main idea is that fat-containing parenteral nutrition (a fat emulsion) carries a higher risk of causing a fat embolism in patients who already have a risk for embolic events, particularly from a long-bone fracture. A fractured femur releases fat from the bone marrow into the bloodstream; adding an IV lipid emulsion increases circulating fat droplets, which can lodge in the lungs and other organs and trigger fat embolism syndrome. That makes a fracture of the femur the situation with the greatest potential for a serious complication from a TPN fat emulsion. In contrast, while gastrointestinal obstruction, severe anorexia nervosa, or chronic diarrhea and vomiting each present other nutrient or metabolic concerns (such as malabsorption, refeeding syndrome risk, or electrolyte imbalances), they do not specifically heighten the risk of fat embolism from lipid emulsions the way a long-bone fracture does.
