- A. blood clotting
- B. transport of oxygen in the blood
- C. muscle contractions

2. Patients maintained using peritoneal dialysis may gain weight because:
- A. their appetite is increased
- B. physical activity is limited
- C. they absorb glucose from the dialysate
- D. they absorb amino acids from the dialysate

3. A client who is postoperative following a liver transplant and weighs 65 kg. Which of the following actions should the nurse plan to take?
- A. Keep the client NPO for the first week postoperative.
- B. Limit caloric content once the client resumes eating.
- C. Stress the importance of safe food-handling practices.
- D. Decrease foods high in carbohydrates once the client resumes eating.
Correct answer: C
Rationale: After a liver transplant, it is crucial to stress the importance of safe food-handling practices to prevent foodborne illnesses, especially due to the client's altered immune system. Keeping the client NPO for the first week postoperative is not recommended as early nutrition support is essential for recovery. Limiting caloric content once the client resumes eating may not be appropriate as they need adequate nutrition for healing. Decreasing foods high in carbohydrates without a specific indication may lead to inadequate nutrient intake, which is not ideal for the client's recovery.

Correct answer: D
Rationale: Magnesium plays a key role in muscle relaxation, enzyme operation, and protein synthesis, but it is not directly involved in regulating body temperature.
