1. What is a common sign of developmental dysplasia of the hip (DDH) in infants?

• A. Dislocated patella
• B. Limited abduction of the hip
• C. Swelling of the knee
• D. Hyperextension of the leg

Correct answer: B

Rationale: Limited abduction of the hip is a common sign of developmental dysplasia of the hip in infants. It indicates possible hip dislocation or instability, making it a key clinical manifestation to assess for DDH. Dislocated patella (Choice A) is not typically associated with DDH. Swelling of the knee (Choice C) and hyperextension of the leg (Choice D) are not specific signs linked to DDH in infants, further supporting why they are incorrect choices.

2. What is one major weakness of a laboratory-based study?

• A. The costs are typically prohibitive.
• B. Findings are difficult to replicate.
• C. Results from animal testing cannot be applied to human beings.
• D. Experimental variables cannot be easily controlled.

Correct answer: C

Rationale: One major weakness of laboratory-based studies is that results from animal testing cannot always be applied to human beings. This limitation arises due to the inherent biological differences between animals and humans, making the generalization of findings challenging. While costs may be a concern in some cases, they do not represent a universal weakness of laboratory-based studies. Findings in such studies can be replicated to ensure validity, and experimental variables can be effectively controlled in a laboratory setting. Choice C is the correct answer because the translatability of results from animal studies to humans is a significant challenge in laboratory-based research, impacting the direct application of findings to human health and well-being.

3. What is a common sign of hypothyroidism in children?

• A. Weight loss
• B. Increased heart rate
• C. Dry skin and constipation
• D. Elevated blood pressure

Correct answer: C

Rationale: Dry skin and constipation are typical signs of hypothyroidism in children. Hypothyroidism results from an underactive thyroid gland, leading to symptoms such as dry skin and constipation. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the thyroid gland is overactive. Increased heart rate (Choice B) and elevated blood pressure (Choice D) are also more characteristic of hyperthyroidism rather than hypothyroidism. Therefore, the correct answer is dry skin and constipation (Choice C) when identifying signs of hypothyroidism in children.

4. What is a primary intervention for a child with a suspected respiratory infection?

• A. Administer antiviral medications
• B. Increase fluid intake and rest
• C. Restrict all physical activity
• D. Provide high-dose vitamin supplements

Correct answer: B

Rationale: Increasing fluid intake and rest is a primary intervention for a child with a suspected respiratory infection because it helps support the body’s recovery and maintains hydration levels. Antiviral medications (Choice A) are only used for specific viral infections and are not routinely recommended for suspected respiratory infections. Restricting physical activity (Choice C) may be necessary in certain cases to prevent overexertion, but it is not a primary intervention. Providing high-dose vitamin supplements (Choice D) may support the immune system in general but is not a primary intervention for a suspected respiratory infection.

5. Which statement best describes the composition of most foods?

• A. Most foods contain a mixture of the three energy nutrients, with one or two predominating.
• B. Foods do not typically contain equal amounts of the three energy nutrients.
• C. Most foods contain mixtures of the three energy nutrients, although only one or two may predominate.
• D. Most foods contain all three energy nutrients in varying amounts.

Correct answer: C

Rationale: The correct answer is C. Most foods contain a mixture of the three energy nutrients (carbohydrates, proteins, fats), with one or two predominating. Choice A is correct because most foods do contain a combination of energy nutrients, with one or two types usually being predominant. Choice B is incorrect as foods typically do not contain equal amounts of carbohydrates, proteins, and fats. Choice D is incorrect because most foods contain all three energy nutrients, not just one or two types.
