1. How many vitamins are known to be required in the diet of human beings?

• A. 5
• B. 8
• C. 10
• D. 13

Correct answer: D

Rationale: The correct answer is D: 13. There are 13 essential vitamins required in the diet of human beings, including vitamins A, C, D, E, K, and the B vitamins. Choice A (5), Choice B (8), and Choice C (10) are incorrect because they do not represent the total number of essential vitamins needed by human beings.

2. What is the appropriate intervention for a child with an undescended testicle?

• A. Wait until puberty
• B. Perform an orchidopexy
• C. Administer hormone therapy
• D. Increase physical activity

Correct answer: B

Rationale: The appropriate intervention for a child with an undescended testicle is to perform an orchidopexy. This surgical procedure is recommended if the testicle has not descended naturally within the first year of life. Waiting until puberty is not advised as early intervention is crucial for optimal outcomes. Administering hormone therapy is not the first-line treatment for an undescended testicle and is typically not recommended. Increasing physical activity does not address the underlying issue of an undescended testicle and is not a suitable intervention.

3. What is one benefit of using a large sample size in an experiment?

• A. Chance variation is less likely to affect the results.
• B. The possibility of a placebo effect is eliminated.
• C. The experiment will be double-blind.
• D. The control group will be similar to the experimental group.

Correct answer: A

Rationale: Corrected Rationale: Using a large sample size reduces the likelihood of chance variation affecting the results, providing more reliable data. Choice B is incorrect because the placebo effect is related to participants' beliefs, not sample size. Choice C is incorrect as double-blind refers to a method of reducing bias, not directly related to sample size. Choice D is incorrect because the similarity between the control and experimental groups is not solely dependent on sample size.

4. What should be assessed in an infant diagnosed with hypertrophic pyloric stenosis?

• A. Diarrhea after each feeding
• B. Gastric pain and vigorous crying
• C. Poor appetite due to poor sucking reflex
• D. An olive-shaped mass right of the midline

Correct answer: D

Rationale: In hypertrophic pyloric stenosis, an olive-shaped mass can often be palpated in the infant's abdomen, which is a hallmark sign of this condition. This mass is located in the right upper quadrant of the abdomen, right of the midline. Choices A, B, and C are incorrect because while infants with hypertrophic pyloric stenosis may experience vomiting (not diarrhea), gastric pain, and irritability, and have feeding difficulties, the key assessment finding specific to this condition is the palpable olive-shaped mass in the abdomen.

5. What dietary recommendation is essential for a child with phenylketonuria (PKU)?

• A. High-protein diet
• B. Low-fat diet
• C. Low-phenylalanine diet
• D. High-fiber diet

Correct answer: C

Rationale: The correct answer is C: 'Low-phenylalanine diet.' Children with phenylketonuria (PKU) need to follow a low-phenylalanine diet to manage the condition. Phenylalanine is an amino acid found in protein-containing foods, and individuals with PKU have difficulty metabolizing it, leading to neurological damage and other complications. Therefore, restricting phenylalanine intake is crucial. Choice A, 'High-protein diet,' is incorrect because high protein intake would increase phenylalanine levels, worsening the condition. Choice B, 'Low-fat diet,' and Choice D, 'High-fiber diet,' are not the primary focus for PKU patients. The key dietary intervention for PKU is controlling phenylalanine intake, which is best achieved through a low-phenylalanine diet.
