1. An essential nutrient is one that ___

• A. must be made in large quantities by the body
• B. can only be synthesized by the body
• C. cannot be made in sufficient quantities by the body
• D. is used to synthesize other compounds in the body

Correct answer: C

Rationale: An essential nutrient is a substance that cannot be made in sufficient quantities by the body itself, so it must be obtained from the diet. Choice A is incorrect because essential nutrients are required in specific amounts, not necessarily large quantities. Choice B is incorrect as essential nutrients cannot be synthesized by the body at all. Choice D is incorrect because although essential nutrients may be used in the synthesis of other compounds, that is not the defining characteristic of an essential nutrient.

2. How should pain be assessed in a nonverbal child?

• A. Ask the parents about the child’s usual behavior
• B. Observe the child’s facial expressions and body movements
• C. Measure the child’s blood pressure
• D. Use a pain rating scale for older children

Correct answer: B

Rationale: Observing the nonverbal child's facial expressions and body movements is crucial in assessing pain. Nonverbal children may not be able to communicate their discomfort verbally, making it essential to rely on physical cues. Asking parents about the child's usual behavior (choice A) may provide some insight but observing the child directly is more direct and reliable. Measuring blood pressure (choice C) is not typically a direct method for assessing pain in nonverbal children. Using a pain rating scale designed for older children (choice D) is also inappropriate for nonverbal children who cannot participate in such self-reporting tools.

3. What is the primary source of energy for the brain and nervous system?

• A. Protein
• B. Fat
• C. Carbohydrate
• D. Glucose

Correct answer: D

Rationale: Glucose is the correct answer as it is the primary source of energy for the brain and nervous system. The brain relies heavily on glucose to function optimally. While protein and fat play essential roles in the body, they are not the primary sources of energy for the brain and nervous system. Carbohydrates, on the other hand, are broken down into glucose, which is then used as fuel by the brain and nervous system.

4. What is a common side effect of corticosteroid therapy in children?

• A. Increased appetite
• B. Decreased blood glucose levels
• C. Inhibited growth
• D. Mood changes

Correct answer: A

Rationale: The correct answer is A: Increased appetite. Corticosteroid therapy commonly causes increased appetite in children. This side effect can lead to weight gain and other metabolic changes. Option B is incorrect because corticosteroid therapy is more likely to result in increased blood glucose levels. Option C is incorrect because corticosteroid therapy can inhibit growth due to its impact on the endocrine system. Option D is incorrect because corticosteroid therapy can lead to mood changes such as irritability or even mood swings rather than improved mood.

5. What is one benefit of using controls in an experiment?

• A. The size of the groups does not matter.
• B. The subjects are unaware of the experiment's details.
• C. The subjects who are treated are balanced against the placebos.
• D. The subjects are similar in all respects except for the treatment being tested.

Correct answer: D

Rationale: The correct answer is D. Controls in an experiment ensure that the subjects are similar in all respects except for the treatment being tested. This allows for a fair comparison between the treatment group and the control group. Choice A is incorrect because the size of the groups is not the primary benefit of using controls. Choice B is incorrect as blinding, not controls, refers to subjects not knowing about the experiment. Choice C is incorrect as it pertains more to randomization than the use of controls.
