Nursing Elites

1. You are a researcher testing out the effects of a new food molecule—MEGA—on bone health. In order to know if it actually travels to bone cells in the body, you first need to find out if it gets absorbed in the bloodstream. You eat a food containing MEGA, and you measure the molecule in your urine and feces. You only detect MEGA in the feces. Was MEGA absorbed?

• A. No—absorbed compounds show up in urine, not feces
• B. Yes—absorbed compounds show up in feces, not urine
• C.
• D.

Correct answer: A

Rationale: If MEGA was only detected in feces and not in urine, it was not absorbed into the bloodstream. Absorbed compounds typically appear in urine after processing by the body. The correct answer is A because the presence of a compound in feces indicates that it was not absorbed by the body and passed through the digestive system. Choices B, C, and D are incorrect as they do not align with the process of absorption and excretion in the body.

2. Cariogenic foods and beverages, which are fermentable carbohydrates that can be metabolized by oral bacteria, reduce salivary pH to what critical level?

• A. 5
• B. 5.5
• C. 6
• D. 6.5

Correct answer: B

Rationale: Cariogenic foods and beverages lower the pH level in the mouth to below 5.5. This is a critical threshold, as it is the point at which enamel begins to demineralize, increasing the risk of dental caries. Therefore, options 'A', 'C', and 'D' are incorrect. Although a pH level of 5, as suggested by option 'A', would indeed lead to demineralization, it's not the threshold value. The pH levels suggested by options 'C' and 'D' (6 and 6.5, respectively) are higher than the critical value of 5.5, which means they would not initiate enamel demineralization and the subsequent risk of dental caries.

3. A nurse is planning a menu for a client with a folic acid deficiency anemia. Which food should the nurse recommend that is high in folate?

• A. 4 slices of roast beef
• B. ½ cup of asparagus
• C. 1 cup part-skim mozzarella cheese
• D. ¼ cup of olives

Correct answer: B

Rationale: The correct answer is B: ½ cup of asparagus. Asparagus is high in folate, making it a suitable recommendation for clients with folic acid deficiency anemia. Folate is essential in the production of red blood cells, which is crucial in managing anemia. Choices A, C, and D do not contain as much folate as asparagus and are not the best options for addressing a folic acid deficiency anemia.

4. What factor has been shown to contribute to poor nutritional health among adolescents?

• A. Most teens choose fruit juice and milk over soda
• B. Many teens consume energy drinks on a regular basis
• C. Teens have busy schedules and rarely drink fluids throughout the day
• D. Teens are more likely to consume low-fat milk

Correct answer: B

Rationale: The correct answer is B because many teens regularly consume energy drinks, which can contribute to poor nutritional health due to their high sugar and caffeine content, leading to unhealthy dietary patterns. Choice A is incorrect because choosing fruit juice and milk over soda would generally be considered a healthier choice. Choice C is incorrect as busy schedules leading to inadequate fluid intake might impact hydration but not necessarily poor nutritional health. Choice D is also incorrect as consuming low-fat milk is not typically a significant factor contributing to poor nutritional health among adolescents.

5. What principle is used when the client with fever loses heat through giving cooling bed bath to lower body temperature?

• A. Radiation C. Evaporation
• B. Convection D. Conduction
• C.
• D.

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
