TPN VS PPN
Review Exam
Q&A
2024
,1. What is the key difference between Parenteral Nutrition (PN) and Total
Parenteral Nutrition (TPN)?
A. PN is given through the gastrointestinal tract, while TPN bypasses the
gastrointestinal tract
B. PN provides partial nutrition, while TPN provides complete nutrition
C. PN is used for short-term nutritional support, while TPN is used for
long-term nutritional support
D. PN is administered orally, while TPN is administered intravenously
Answer: A. PN is given through the gastrointestinal tract, while TPN
bypasses the gastrointestinal tract
Rationale: TPN is administered intravenously, bypassing the
gastrointestinal tract, while PN can be administered through various routes
including oral, enteral, or parenteral.
2. Which of the following is a common indication for using TPN over
PPN?
A. Severe malnutrition
B. Mild dehydration
C. Post-operative recovery
D. Short-term nutritional support
Answer: A. Severe malnutrition
Rationale: TPN is typically used in cases of severe malnutrition or when
the gastrointestinal tract is unable to absorb nutrients adequately.
3. What is the primary administration route for PPN?
A. Oral
B. Nasogastric tube
C. Central venous catheter
D. Peripheral vein
Answer: D. Peripheral vein
Rationale: PPN is administered through a peripheral vein, while TPN is
administered through a central venous catheter.
4. Which of the following nutrients is commonly included in TPN
formulations but may be limited or omitted in PPN?
A. Carbohydrates
B. Proteins
C. Lipids
, D. Vitamins and minerals
Answer: C. Lipids
Rationale: Lipids are commonly included in TPN formulations to provide
essential fatty acids and calories, while they may be limited or omitted in
PPN due to the risk of phlebitis.
5. Which of the following is a potential complication of TPN
administration that is less likely to occur with PPN?
A. Catheter-related infections
B. Hyperglycemia
C. Electrolyte imbalances
D. Malabsorption
Answer: A. Catheter-related infections
Rationale: TPN administration carries a higher risk of catheter-related
infections due to the use of central venous catheters, while PPN
administered through peripheral veins has a lower risk of infection.
6. In which of the following clinical scenarios would PPN be the preferred
choice over TPN?
A. Patient with severe malnutrition
B. Patient with short-term post-operative recovery
C. Patient with gastrointestinal obstruction
D. Patient with chronic pancreatitis
Answer: B. Patient with short-term post-operative recovery
Rationale: PPN is typically used for short-term nutritional support in
patients who are able to tolerate oral intake but require supplemental
nutrition, such as those recovering from surgery.
7. Which of the following is a major advantage of TPN over PPN?
A. Lower risk of catheter-related infections
B. Improved absorption of nutrients
C. Ability to provide complete nutrition
D. Cost-effectiveness
Answer: C. Ability to provide complete nutrition
Rationale: TPN can provide complete nutrition to patients who cannot
tolerate oral or enteral nutrition, while PPN may not provide all essential
nutrients in sufficient quantities.
