FIPP 6: TPN Exam | Updated Questions with
100% Correct Answers | 2025/2026 Study
Guide
,1. Which macronutrient in TPN is the primary source of calories?
A. Amino acids
B. Dextrose
C. Lipid emulsion
D. Sterile water
Dextrose is a carbohydrate that provides most of the non-protein calories in
a standard TPN formulation.
2. What is the main role of amino acids in TPN?
A. Primary energy source
B. Protein synthesis and tissue repair
C. Fluid balance
D. Antioxidant defense
Amino acids supply the building blocks needed for protein synthesis and
repair, especially in catabolic patients.
3. Which component of TPN provides essential fatty acids and a concentrated
source of energy?
A. Dextrose
B. Amino acids
C. Lipid emulsion
D. Trace elements
Lipid emulsions deliver essential fatty acids and additional calories, often in
a separate infusion or admixture.
4. Which electrolyte is commonly included in TPN to support neuromuscular
and cardiac function?
, A. Potassium
B. Iodine
C. Fluoride
D. Boron
Potassium is a key electrolyte in TPN and must be monitored closely because
both deficiency and excess can cause cardiac and neuromuscular
complications.
5. Which trace element is important for wound healing and immune function
in TPN?
A. Zinc
B. Lead
C. Aluminum
D. Mercury
Zinc is a trace element included in TPN that supports wound healing,
immune function, and protein synthesis.
6. Which vitamin is typically included in TPN for fat-soluble antioxidant and
vision support?
A. Vitamin A
B. Vitamin C only
C. Thiamine only
D. Folate only
Vitamin A is a fat-soluble vitamin included in TPN and contributes to vision,
immune function, and antioxidant defenses.
, 7. Which clinical situation is a common indication for TPN?
A. Mild nausea for 1 day
B. Short bowel syndrome with severe malabsorption
C. Ability to eat but poor appetite
D. Uncomplicated gastroenteritis
TPN is indicated when the gastrointestinal tract cannot absorb adequate
nutrients, as in short bowel syndrome or severe malabsorption.
8. Which condition is generally a contraindication to initiating TPN?
A. A functional gastrointestinal tract that can tolerate enteral nutrition
B. Massive small bowel resection
C. Prolonged ileus
D. Severe pancreatitis with intolerance to enteral feeding
If the gut works and enteral nutrition is feasible, it is preferred over TPN
because it is safer and more physiologic.
9. Which complication is most specifically associated with central venous
access in TPN?
A. Catheter-related bloodstream infection
B. Hyperkalemia
C. Hepatic steatosis
D. Essential fatty acid deficiency
Central venous catheters used for TPN can cause catheter-related
bloodstream infection, making sterile technique and line care critical.
10.Which laboratory parameter should be monitored closely during TPN to
detect hyperglycemia?
