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. Why is a pulse oximeter attached to Mr. Dizon's finger?

• A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
• B. To check the level of the patient's tissue perfusion
• C. To measure the effectiveness of the patient's anti-hypertensive medications
• D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop

Correct answer: D

Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.

3. A client who underwent surgical placement of a colostomy is being cared for by a nurse. Which of the following statements indicates the client understands the dietary teaching?

• A. "Eating yogurt can help decrease the amount of gas that I have."?
• B. "I should eliminate pasta from my diet so that I don't have as many loose stools."?
• C. "My largest meal of the day should be in the evening."?
• D. "Carbonated beverages can help control odor."?

Correct answer: D

Rationale: The correct answer is D. Carbonated beverages can help control odor in clients with colostomies. This is because carbonated drinks can help decrease odor by reducing the production of odoriferous compounds in the colon. Choices A, B, and C are incorrect. Eating yogurt may help regulate bowel movements but does not specifically address odor control associated with colostomies. Eliminating pasta from the diet to reduce loose stools is not necessary for colostomy care. The timing of the largest meal of the day is not directly related to dietary teaching for colostomy care.

4. A condition that is conducive to the development of dental caries is said to be _____.

• A. periodontal
• B. cariogenic
• C. gingival
• D. bacteriophilic

Correct answer: B

Rationale: A condition that is conducive to the development of dental caries is described as cariogenic. Cariogenic refers to foods or conditions that promote the development of dental caries by providing an environment for bacteria to thrive and produce acids that erode tooth enamel. Choice A, periodontal, is incorrect as it relates to the supporting structures of the teeth rather than the development of dental caries. Choice C, gingival, is also incorrect as it pertains to the gums rather than the causation of dental caries. Choice D, bacteriophilic, is not the term commonly used to describe conditions that lead to dental caries, making it an incorrect choice.

5. Which step of the management process is concerned with Policy making and Stating the goals and objective of the institution?

• A. Planning
• B. Organizing
• C. Directing
• D. Controlling

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
