1. The mechanism behind most CKD in patients without diabetes is mediated by:

• A. enzyme systems
• B. immune systems
• C. catabolic systems
• D. hormonal systems

Correct answer: B

Rationale: In non-diabetic patients, CKD is often mediated by immune system responses. Chronic inflammation triggered by immune system dysfunction can contribute to progressive kidney damage. Therefore, the correct answer is 'immune systems.' Choices A, C, and D are incorrect because CKD in non-diabetic patients is primarily associated with immune system abnormalities rather than enzyme, catabolic, or hormonal systems.

2. Which nutrient is critical for wound healing and immune function?

• A. Vitamin B12
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: Vitamin C is essential for collagen formation and immune function.

3. How many grams of protein per day are recommended for a person weighing 150 lbs?

• A. 120
• B. 85
• C. 187.5
• D. 54

Correct answer: D

Rationale: The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight. To convert pounds to kilograms, divide the weight in pounds by 2.2. Therefore, a 150 lb person weighs approximately 68 kg (150 / 2.2 = 68). Multiplying 68 kg by 0.8 grams gives us 54 grams of protein per day. Choices A, B, and C are incorrect as they do not align with the RDA calculation based on body weight.

4. Electrolytes create _____, which is caused by water following electrolytes within or between cells.

• A. energy
• B. active transport
• C. passive diffusion
• D. osmotic pressure

Correct answer: D

Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.

5. A nurse is caring for a client who is receiving parenteral nutrition. Which of the following findings indicates the therapy is effective?

• A. Client has soft, formed bowel movements.
• B. Client’s mucous membranes are pink.
• C. Client reports ability to complete ADLs.
• D. Client’s blood glucose level is within the expected reference range.

Correct answer: D

Rationale: The correct answer is D because having a blood glucose level within the expected reference range indicates that parenteral nutrition is effectively meeting the client's nutritional needs. Choices A, B, and C are incorrect because soft, formed bowel movements, pink mucous membranes, and the ability to complete activities of daily living do not directly reflect the effectiveness of parenteral nutrition therapy.
