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. 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.

3. Each of the following is a fat-soluble vitamin except for one. Which is the exception?

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

Correct answer: B

Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.

4. Which of the following interventions should be considered the highest priority when caring for June, who has hemiparesis secondary to a stroke?

• A. Position June in an upright lateral position
• B. Perform range of motion exercises
• C. Apply antiembolic stockings
• D. Use hand rolls or pillows for support

Correct answer: C

Rationale: The correct answer is C, 'Apply antiembolic stockings'. In the case of a patient who has experienced a stroke and is suffering from hemiparesis, the highest priority intervention is to prevent further complications such as deep vein thrombosis (DVT), which can be life-threatening. Antiembolic stockings are used to increase venous blood flow velocity and reduce the risk of DVT. Choice 'A', positioning June in an upright lateral position, while important for overall care, is not the highest priority. Choice 'B', performing range of motion exercises, is an important part of recovery but not the immediate priority. Choice 'D', using hand rolls or pillows for support, is also a valuable intervention but does not address the most pressing risk of further complications.

5. The nurse is completing a nutritional assessment on a client. Which statement made by the client is most concerning to the nurse?

• A. "I notice when I take a vitamin E supplement, I bruise more easily."
• B. "I work nights and rarely go outside during the day."
• C. "I take warfarin, so I need to limit the amount of green leafy vegetables I eat."
• D. "My vitamin supplement has the recommended daily allowance of vitamin A."

Correct answer: A

Rationale: The correct answer is A. Excessive intake of vitamin E can increase the risk of bleeding as it acts as a blood thinner. Bruising easily may indicate too much vitamin E. Choice B is not as concerning as it describes a lifestyle that may lead to vitamin D deficiency due to lack of sunlight exposure. Choice C shows awareness of the interaction between warfarin and vitamin K, which is expected. Choice D indicates knowledge of the vitamin A content in the supplement, which is not a cause for concern.
