1. 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
Correct answer: C
Rationale: Glucose from the peritoneal dialysis solution can be absorbed into the bloodstream, leading to weight gain if not balanced with diet and activity.
2. Which two dietary components may help decrease blood cholesterol levels?
- A. Omega-3 fatty acids and soluble fiber
- B. Short-chain fatty acids and insoluble fiber
- C. Trans fatty acids and potassium
- D. Cis fatty acids and calcium
Correct answer: A
Rationale: The correct answer is A: Omega-3 fatty acids and soluble fiber. Omega-3 fatty acids are known to reduce triglycerides, while soluble fiber helps to lower LDL cholesterol levels. Both of these components are beneficial in managing blood cholesterol levels. Choice B, short-chain fatty acids and insoluble fiber, is incorrect as they do not have the same cholesterol-lowering effects as omega-3 fatty acids and soluble fiber. Choice C, trans fatty acids and potassium, is incorrect as trans fatty acids can raise LDL cholesterol levels and increase the risk of heart disease. Choice D, cis fatty acids and calcium, is incorrect as cis fatty acids are common in natural fats and do not specifically help in reducing blood cholesterol levels.
3. What action should the nurse take first for a client with Listeria food poisoning?
- A. Educate the client on safe food practices.
- B. Start a traceback to identify the source of the outbreak.
- C. Report the case to the county board of health.
- D. Ask the client if they have consumed any unpasteurized products.
Correct answer: D
Rationale: Identifying the source of Listeria is crucial for preventing further cases.
4. What primarily determines the Dietary Reference Intake (DRI) for protein?
- A. Intake of fatty acids
- B. Gender
- C. Height
- D. Body weight
Correct answer: D
Rationale: The Dietary Reference Intake (DRI) for protein is primarily determined by an individual's body weight. This is because the body's protein requirement is proportionate to its size, which is generally reflected in the body weight. Therefore, choice D is correct. Choices A, B, and C are incorrect: While factors such as fatty acid intake, gender, and height can influence an individual's overall nutritional needs, they do not directly determine the DRI for protein.
5. _____ neutralizes stomach acid in the small intestine:
- A. saliva
- B. gastric mucus
- C. bicarbonate ions
- D. enzymes
Correct answer: C
Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.
