1. The most energy-rich nutrient is:

• A. carb
• B. fat
• C. protein
• D. water

Correct answer: B

Rationale: Fat provides 9 kcal per gram, making it the most energy-rich nutrient compared to carbohydrates and proteins, which provide 4 kcal per gram.

2. Which food is a high source of prebiotics?

• A. Chicken
• B. Garlic
• C. White rice
• D. Cheese

Correct answer: B

Rationale: Garlic is the correct answer. It is high in prebiotics, which are non-digestible fibers that promote the growth of beneficial gut bacteria. Chicken, white rice, and cheese are not significant sources of prebiotics. Chicken is a good source of protein, white rice is a carbohydrate, and cheese is a dairy product, none of which are high in prebiotics.

3. 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.

4. 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.

5. A nurse is caring for a client who is to receive a mechanically altered diet. Which of the following client food choices necessitates intervention by the nurse?

• A. Scrambled eggs
• B. Cottage cheese
• C. Piece of wheat toast
• D. Sliced banana

Correct answer: D

Rationale: The correct answer is 'Sliced banana.' A mechanically altered diet is designed for clients who have difficulty chewing or swallowing. Sliced bananas, due to their texture and potential choking hazard for clients with swallowing difficulties, would necessitate intervention by the nurse. Scrambled eggs, cottage cheese, and a piece of wheat toast are softer and safer options for clients on a mechanically altered diet, making them appropriate choices.
