1. 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.

2. 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).

3. Farah is viewing an exciting sports match of her favorite team and eating because of nervousness. Her food choice will most likely be based on ___.

• A. regional cuisines
• B. preferences
• C. emotional comfort
• D. positive association

Correct answer: C

Rationale: During stressful situations like watching an exciting sports match, individuals often seek emotional comfort through food. This emotional connection can lead Farah to choose foods that provide comfort or familiarity rather than being based on regional cuisines (choice A), general preferences (choice B), or positive associations (choice D). Farah's food choice is likely driven by the need for emotional comfort to alleviate her nervousness, making option C the most suitable answer.

4. Non-nutrient substances found in plant foods that may demonstrate biological activity in the body are commonly known as ___

• A. Bioenhancements
• B. Inorganic fibers
• C. Phytochemicals
• D. Phytoactive chemicals

Correct answer: C

Rationale: Phytochemicals are bioactive compounds found in plant foods that may affect health. They are known for their potential health benefits, such as antioxidant and anti-inflammatory properties. Choices A, B, and D are incorrect. 'Bioenhancements' is not a term used to describe non-nutrient substances in plant foods. 'Inorganic fibers' do not refer to bioactive compounds found in plants. 'Phytoactive chemicals' is not a commonly used term in nutrition science to describe these compounds.

5. What is a key aspect of care for a child with an indwelling urinary catheter?

• A. Increase fluid intake
• B. Monitor for signs of infection
• C. Restrict mobility
• D. Administer daily antibiotics

Correct answer: B

Rationale: Monitoring for signs of infection is crucial when caring for a child with an indwelling urinary catheter. This is because catheter-associated urinary tract infections are common in such cases. Increasing fluid intake can be beneficial, but monitoring for infection takes precedence as it is crucial to prevent complications. Restricting mobility is not a key aspect of care for a child with an indwelling urinary catheter unless specifically advised by a healthcare provider. Administering daily antibiotics without proper assessment and indication can lead to antibiotic resistance and is not a standard practice in caring for a child with an indwelling urinary catheter.
