1. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.

Correct answer: A

Rationale: Both statements are true. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.

2. A client is on a 2,000-calorie American Diabetes Association (ADA) diet and substitutes whole milk with skim milk. Which of the following items can the client add to the oatmeal on his breakfast tray?

Correct answer: B

Rationale: The correct answer is one ounce of raisins. Raisins are a healthy option to add to oatmeal as they provide natural sweetness without added sugars. They are a good source of fiber and essential nutrients. Option A, one 1/8 teaspoon of salt, is not necessary for flavoring oatmeal. Option C, one tablespoon of low-fat margarine, may add unnecessary fat to the meal. Option D, one teaspoon of brown sugar, adds extra sugar, which should be limited in a diabetes-friendly diet.

3. 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.

4. Which of the following questions illustrates the group role of encourager?

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 of the following foods provides the most protein?

Correct answer: A

Rationale: The correct answer is 'Beans.' Beans are a rich source of plant-based protein, making them the best option among the listed foods for protein content. Red peppers, asparagus, and celery are not significant sources of protein compared to beans, hence they are incorrect choices for this question.
