1. What is a common sign of congenital hip dysplasia in infants?

• A. Symmetrical hip movement
• B. Limited range of motion in the hip
• C. Swelling of the knees
• D. Dislocated patella

Correct answer: B

Rationale: Limited range of motion in the hip, often noted as a limitation in abduction, is a common sign of congenital hip dysplasia. This limitation is due to the abnormal development of the hip joint, affecting its movement. Symmetrical hip movement (Choice A) is not a characteristic sign of congenital hip dysplasia. Swelling of the knees (Choice C) is not typically associated with this condition. Dislocated patella (Choice D) refers to a different anatomical structure and is not a common sign of congenital hip dysplasia.

2. Approximately how many milliliters are contained in a half-cup of milk?

• A. 50
• B. 85
• C. 120
• D. 170

Correct answer: C

Rationale: A half-cup of milk is equivalent to approximately 120 milliliters. This conversion is standard and commonly used in cooking and baking. Choice A (50 milliliters) is too low for a half-cup measurement. Choice B (85 milliliters) is also lower than the standard half-cup measurement of 120 milliliters. Choice D (170 milliliters) is too high for a half-cup, making it an incorrect option.

3. Why is randomization important in a scientific experiment?

• A. To minimize the impact of confounding variables.
• B. To eliminate bias in the assignment of subjects to groups.
• C. To contribute to the accuracy and validity of the experiment's results.
• D. To prevent systematic differences between groups.

Correct answer: B

Rationale: Randomization is crucial in a scientific experiment to eliminate bias in the assignment of subjects to groups. By randomly assigning subjects, it helps ensure that any differences observed in the outcomes are due to the experimental treatment and not to preexisting differences between groups. Choice A is incorrect because randomization does not guarantee representativeness but rather minimizes the impact of confounding variables. Choice C is not entirely accurate; while randomization can contribute to accuracy and validity, its primary purpose is to reduce bias. Choice D is incorrect as the goal of randomization is not to balance the number of subjects but to prevent systematic differences between groups.

4. What is the most common symptom of appendicitis in children?

• A. Vomiting and diarrhea
• B. Fever and abdominal pain
• C. Rash and joint pain
• D. Difficulty breathing

Correct answer: B

Rationale: The correct answer is B: Fever and abdominal pain. In children, appendicitis commonly presents with fever and abdominal pain. The pain typically begins around the umbilicus and then moves to the lower right quadrant. Choices A, C, and D are incorrect because vomiting and diarrhea, rash and joint pain, and difficulty breathing are not typical symptoms of appendicitis in children.

5. What is an important aspect of managing a child with asthma in a school setting?

• A. Limiting physical activity
• B. Ensuring access to emergency medications
• C. Reducing the number of classes attended
• D. Avoiding interaction with other students

Correct answer: B

Rationale: The correct answer is B: Ensuring access to emergency medications. In a school setting, it is crucial to have emergency medications available for a child with asthma in case of an asthma attack. This helps in managing asthma effectively and promptly. Choices A, C, and D are incorrect because limiting physical activity, reducing the number of classes attended, and avoiding interaction with other students are not recommended strategies for managing asthma in a school setting. Encouraging physical activity, ensuring regular attendance, and promoting social interactions are important for the overall well-being of a child with asthma.
