1. Which chemical structure is represented by glycerol combined with two fatty acids?

• A. Compound lipids
• B. Monoglycerides
• C. Diglycerides
• D. Structural lipids

Correct answer: C

Rationale: The correct answer is C: Diglycerides. A diglyceride is a glycerol molecule combined with two fatty acids. This is a common form of fat during digestion and absorption. Choice A, Compound lipids, is incorrect because these lipids are composed of simple lipids plus additional compounds, which is not the case with a glycerol molecule combined with two fatty acids. Choice B, Monoglycerides, is incorrect because these are glycerol molecules combined with only one fatty acid, not two. Lastly, choice D, Structural lipids, is incorrect because these are major components of cell membranes and do not directly relate to the combination of glycerol and two fatty acids.

2. A nurse is caring for a client who is well-hydrated and who demonstrates no evidence of anemia. Which of the following laboratory values gives the nurse an assessment of the adequacy of the client's protein uptake and synthesis?

• A. Albumin
• B. Calcium
• C. Sodium
• D. Potassium

Correct answer: A

Rationale: The correct answer is Albumin. Albumin is a protein made by the liver and is a key indicator of the body's protein status. Low levels of albumin can indicate inadequate protein intake or synthesis. Choices B, C, and D (Calcium, Sodium, and Potassium) are not direct indicators of protein uptake and synthesis. Calcium is related to bone health, Sodium to fluid balance, and Potassium to nerve and muscle function.

3. What is the major diet-derived antioxidant found in cell membranes?

• A. B12
• B. beta-carotene
• C. vitamin E
• D. vitamin A

Correct answer: C

Rationale: The correct answer is vitamin E. Vitamin E is the major antioxidant found in cell membranes, where it plays a crucial role in protecting them from oxidative damage. Although B12, beta-carotene, and vitamin A are important nutrients with specific functions in the body, they are not the primary antioxidants found in cell membranes. Vitamin E specifically localizes in cell membranes to neutralize free radicals and prevent lipid peroxidation, making it an essential antioxidant for cellular health.

4. Which is the best description of a full-liquid diet?

• A. Most suitable for individuals with an ileostomy
• B. Suitable for individuals with lactose intolerance
• C. Contains low saturated fat and high fiber
• D. Provides adequate nutrients and is easily digested

Correct answer: D

Rationale: The correct answer is D because a full-liquid diet is designed to provide adequate nutrients while being easily digested. Choices A and B are incorrect because a full-liquid diet is not specifically tailored for individuals with an ileostomy or lactose intolerance. Choice C is also incorrect as it describes characteristics that are not defining features of a full-liquid diet.

5. A nurse is caring for a client with a major burn injury and is receiving TPN. Which of the following lab tests is the priority for the nurse to use to confirm the client is receiving adequate nutrition?

• A. Iron
• B. Magnesium
• C. Folic acid
• D. Prealbumin

Correct answer: D

Rationale: Prealbumin is a sensitive indicator of protein status and nutrition, making it a priority for assessing nutritional adequacy in clients receiving TPN. Iron, magnesium, and folic acid levels are important for overall health but do not specifically indicate nutritional adequacy in the context of TPN administration.
