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. During the acute phase of a burn, the priority nursing intervention in caring for this client is:

• A. Prevention of infection
• B. Pain management
• C. Prevention of bleeding
• D. Fluid resuscitation

Correct answer: D

Rationale: During the acute phase of a burn, fluid resuscitation is the priority nursing intervention. This phase is characterized by fluid loss and the risk of hypovolemic shock. Administering fluids is crucial to maintain perfusion and prevent complications such as organ failure. While prevention of infection, pain management, and prevention of bleeding are important aspects of burn care, fluid resuscitation takes precedence in the acute phase to stabilize the client's condition and prevent further damage.

3. Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?

• A. The DRIs replace the older recommended daily allowances
• B. Current DRIs attempt to estimate required nutrients to improve long-term health
• C. DRIs specifically address individuals whose requirements are affected by a disease state
• D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients

Correct answer: C

Rationale: The correct answer is C. DRIs are intended for the general population and do not specifically address disease states, which are managed with different clinical guidelines. Choice A is correct as DRIs have replaced the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate the required nutrients for long-term health. Choice D is correct as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.

4. You will give health instructions to Carlo, a case of bronchial asthma. The health instruction will include the following, EXCEPT:

• A. Avoid emotional stress and extreme temperature
• B. Avoid pollution like smoking
• C. Avoid pollens, dust, seafood
• D. Practice respiratory isolation

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. Which consumption pattern of fermentable carbohydrate is considered most cariogenic?

• A. A single exposure to a large quantity
• B. A single exposure to a small quantity
• C. Multiple exposures of small quantities
• D. Multiple exposures followed by chewing sugarless gum

Correct answer: C

Rationale: Multiple exposures of small quantities are considered most cariogenic. The total amount of dietary fermentable carbohydrate seems to matter less than the form and frequency in which it is consumed. Having multiple exposures of even small quantities of fermentable carbohydrate throughout the day promotes a highly cariogenic environment in the mouth. Choices A and B, involving single exposures, are less cariogenic as they do not sustain the fermentation process over time. Choice D suggests a beneficial practice by chewing sugarless gum after exposures, which can reduce the risk, making it less cariogenic compared to multiple exposures of small quantities.
