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.

Correct Answer: A

Rationale: The correct answer is to assess the response to verbal stimuli first in a child with suspected head trauma. This assessment helps in determining the child's level of consciousness and neurological status. Assessing the response to verbal stimuli allows healthcare providers to quickly evaluate if the child is alert, oriented, and able to communicate effectively. This initial assessment is crucial in identifying any immediate concerns related to the child's neurological function. Choices B, C, and D are not the primary assessments in cases of suspected head trauma. While pupillary reaction, skin color, and heart rate are important assessments in trauma situations, assessing the response to verbal stimuli takes precedence in evaluating the neurological status of a child with head trauma.

Correct Answer: A

Rationale: Corrected Rationale: Emphasizing the importance of blood glucose monitoring is crucial for managing type 1 diabetes effectively. Monitoring blood glucose levels helps in maintaining optimal control of the condition, adjusting treatment plans as necessary, and preventing complications. Choice B is incorrect because insulin therapy is the mainstay treatment for type 1 diabetes to regulate blood sugar levels. Choice C is incorrect because while diet is important, encouraging a high-carbohydrate diet can lead to fluctuations in blood sugar levels. Choice D is incorrect because alternative therapies should not replace standard medical treatment like insulin therapy in type 1 diabetes management.

Correct Answer: D

Rationale: The correct answer is D, Kilocalorie. The term kilocalorie, often referred to as a calorie, is the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. While Choice A, Calorie, is technically correct, it is not the most specific term for the described amount of heat. Choice B, Joule, is a unit of energy but not specifically related to the amount of heat required to raise the temperature of water. Choice C, Kilojoule, is also a unit of energy but not the precise term for the heat required to raise the temperature of water by one degree Celsius.

Correct Answer: A

Rationale: The correct answer is A: Monitoring electrolyte levels. In the management of congenital adrenal hyperplasia, it is crucial to monitor electrolyte levels to prevent imbalances and related complications. Restricting physical activity (choice B) is not a typical aspect of care for this condition. Administering high doses of vitamin A (choice C) is not a standard treatment for congenital adrenal hyperplasia and can be harmful in excess. Providing a high-protein diet (choice D) may be beneficial for some conditions but is not a specific requirement for managing congenital adrenal hyperplasia.
