1. Which of the following is NOT a physiological role of proteins?

Correct answer: D

Rationale: Proteins play a diverse range of physiological roles in the body, such as providing resistance to disease, regulating fluid balance, and repairing tissues. However, they are not the primary source of energy for the body. Carbohydrates and fats typically fulfill this role. Therefore, choice D is the correct answer, as it is not a function that proteins perform. Conversely, choices A, B, and C are all physiological functions of proteins, making them incorrect responses to this particular question.

2. Which is most likely to initiate periodontal disease?

Correct answer: D

Rationale: Plaque biofilm is the primary initiator of periodontal disease, as it harbors bacteria that can lead to inflammation and destruction of the periodontal tissues.

3. Which of the following nutrients does not provide energy?

Correct answer: D

Rationale: Proteins, carbohydrates, and fats are macronutrients that provide energy in the form of calories when consumed and metabolized by the body. Each gram of protein or carbohydrate provides about 4 calories, and each gram of fat provides about 9 calories. On the other hand, vitamins do not provide energy or calories. They are micronutrients that are essential for various biochemical and physiological processes in the body, including the metabolism of macronutrients. However, they do not contribute directly to the energy supply. Therefore, the correct answer is 'D: Vitamins'. Choices A, B, and C (Proteins, Carbohydrates, and Fats) are incorrect because they are macronutrients that do provide energy/calories when metabolized.

4. A nurse is teaching a client who needs to increase their daily fluid intake. Which of the following foods has the highest percentage of water by weight?

Correct answer: C

Rationale: The correct answer is Lettuce. Lettuce has the highest percentage of water by weight among the options provided, making it an excellent choice to increase fluid intake. Yogurt and milk have some water content but are not as high in water percentage as lettuce. Honey, on the other hand, contains very little water and is not a good choice for increasing fluid intake.

5. The nurse is correct in performing suctioning when she applies the suction intermittently during:

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.
