1. What is one function of water in the human body?

• A. Water provides calories for energy.
• B. Water helps transport nutrients and waste products.
• C. Water acts as a solvent for many biological reactions.
• D. Water maintains body temperature.

Correct answer: B

Rationale: The correct answer is B: Water helps transport nutrients and waste products. Water plays a crucial role in the body by aiding in the transportation of essential nutrients to cells and removing waste products. While water is essential for various metabolic processes, it does not provide calories for energy (choice A). Although water can act as a solvent for biological reactions (choice C), its primary function is not as a solvent. Additionally, while water does help in regulating body temperature to some extent, its main role is not to maintain body temperature (choice D).

2. What is a key aspect of managing a child with cystic fibrosis?

• A. Regular pulmonary function tests
• B. Daily administration of antibiotics only
• C. High-sugar diet
• D. Limiting all physical activities

Correct answer: A

Rationale: Regular pulmonary function tests are a key aspect of managing a child with cystic fibrosis. These tests help monitor lung function and disease progression effectively, providing valuable information for healthcare providers to make timely interventions and adjustments to treatment plans. Daily administration of antibiotics alone (Choice B) is important but not the sole key aspect of managing cystic fibrosis. A high-sugar diet (Choice C) is not recommended for individuals with cystic fibrosis as it can exacerbate health issues. Limiting all physical activities (Choice D) is not beneficial as regular exercise is important for overall health and lung function in individuals with cystic fibrosis.

3. Which individual is making a food choice based on negative association?

• A. A tourist from China who rejects a hamburger due to unfamiliarity
• B. A child who spits out his mashed potatoes because they taste too salty
• C. A teenager who grudgingly accepts an offer for an ice cream cone to avoid offending a close friend
• D. An elderly gentleman who refuses a peanut butter and jelly sandwich because he considers it a child's food

Correct answer: D

Rationale: Choice D is the correct answer because the elderly gentleman is refusing the peanut butter and jelly sandwich due to his negative association of considering it a child's food. This negative association influences his food choice. Choices A, B, and C do not involve negative associations with the food being consumed. Choice A is based on unfamiliarity, Choice B is due to taste preference, and Choice C is driven by social considerations rather than negative food association.

4. What is a common complication of untreated type 1 diabetes in children?

• A. Diabetic ketoacidosis
• B. High blood pressure
• C. Asthma
• D. Frequent infections

Correct answer: A

Rationale: Diabetic ketoacidosis is a serious complication of untreated type 1 diabetes in children. It is characterized by high blood sugar levels, ketones in the urine, and acidosis. Prompt medical attention is required to manage this condition. High blood pressure (Choice B) can be a complication of diabetes but is not as directly linked to untreated type 1 diabetes as diabetic ketoacidosis. Asthma (Choice C) and frequent infections (Choice D) are not typically associated with untreated type 1 diabetes in children.

5. 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.
