1. Which physiologic role does vitamin C play in the body?

• A. Transcribing DNA to RNA
• B. Absorption and regulation of calcium
• C. Protects integrity of cellular membranes
• D. Catalyst for synthesis of blood-clotting factors

Correct answer: C

Rationale: Vitamin C plays a crucial role in protecting the integrity of cellular membranes. It is essential for collagen synthesis, which is important for wound healing and maintaining skin, blood vessels, and other tissues. Choice A is incorrect as the transcription of DNA to RNA is facilitated by vitamin A. Choice B is incorrect as calcium absorption and regulation are functions of vitamin D. Choice D is incorrect as vitamin K serves as a catalyst for the synthesis of blood-clotting factors, not vitamin C.

2. A nurse is providing teaching to an obese client who has gestational diabetes and is at 25 weeks of gestation. Which of the following statements made by the client indicates a need for further teaching?

• A. This does not mean that my baby will have this disease.
• B. This means that I will have diabetes for the rest of my life.
• C. If I feel dizzy, I should drink six ounces of a non-diet soda.
• D. Being obese might be one reason why I developed diabetes.

Correct answer: B

Rationale: The statement 'This means that I will have diabetes for the rest of my life' indicates a need for further teaching.

The other choices are correct or provide appropriate information: A) Understanding that gestational diabetes does not mean the baby will have the disease is accurate. C) Advising to drink non-diet soda if feeling dizzy is incorrect and potentially harmful due to the sugar content. D) Recognizing that obesity can be a risk factor for developing diabetes is a valid statement.

• A. 4%
• B. 21%
• C. 34%
• D. 49%

Correct answer: B

Rationale: The correct answer is B: '21%'. Approximately 21% of persons in the United States who have HIV infection are unaware that they are infected. This percentage represents a significant portion of individuals who are not aware of their HIV status, highlighting the importance of increased testing and awareness campaigns. Choices A, C, and D are incorrect as they do not align with the estimated percentage provided in the context.

4. A nurse is teaching a client about preparing low-fat meals. The nurse should include that which of the following oils contains saturated fat?

• A. Corn
• B. Olive
• C. Canola
• D. Coconut

Correct answer: D

Rationale: Coconut oil contains a high amount of saturated fat, which can increase LDL cholesterol levels and the risk of heart disease. Olive, corn, and canola oils are primarily unsaturated fats, which are considered heart-healthy fats. Olive oil, in particular, is rich in monounsaturated fats, while corn and canola oils are good sources of polyunsaturated fats. Therefore, the correct answer is Coconut because it contains saturated fat, unlike the other options.
