1. Health practitioners evaluate disease progression in HIV-infected patients by measuring the concentrations of helper T cells and circulating virus, called _____.

• A. cross resistance
• B. the immune response
• C. acquired resistance
• D. the viral load

Correct answer: D

Rationale: The viral load is the measure of the amount of circulating virus in the blood and is used to evaluate the progression of HIV infection.

2. A woman who has been following a vegan diet may need ____ supplements.

• A. vitamin C and vitamin A
• B. vitamin D and vitamin B12
• C. vitamin E and K
• D. vitamin D and niacin

Correct answer: B

Rationale: The correct answer is B: vitamin D and vitamin B12. Vegans may need to supplement vitamin D and B12 as these nutrients are mainly found in animal products. While choices A, C, and D are essential vitamins, they are not typically lacking in a vegan diet. Vitamin C can be obtained from various plant sources, vitamin A can be derived from beta-carotene in plants, and vitamin E and K are also found in plant-based foods. Niacin, although important, can be sourced from plant-based sources and is not a common deficiency in vegan diets.

3. A nurse is reinforcing teaching about food choices with the mother of an 8-month-old infant. Which of the following statements by the mother indicates a need for further teaching?

• A. I will give my child strained carrots and mashed egg yolks.
• B. I will give my child rice cereal and crackers.
• C. I will give my child pureed liver and strained pears.
• D. I will give my child applesauce and green peas.

Correct answer: B

Rationale: Choice B, 'I will give my child rice cereal and crackers,' indicates a need for further teaching. Infants should not be given crackers at 8 months of age due to the risk of choking. Rice cereal is appropriate for infants, but it should be introduced carefully to avoid digestive issues. Choices A, C, and D are appropriate food choices for an 8-month-old infant, providing a variety of nutrients and textures suitable for their age and developmental stage.

4. 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.

5. A vegan patient might be at risk for deficiency in which of the following nutrients?

• A. Vitamin B12
• B. Vitamin C
• C. Carbohydrates
• D. Fiber

Correct answer: A

Rationale: The correct answer is Vitamin B12. Vitamin B12 is primarily found in animal products, so individuals following a vegan diet are at risk of deficiency as they do not consume these sources. Vitamin C, Carbohydrates, and Fiber are not specifically at risk for deficiency in vegan diets as they can be obtained from plant-based sources.
