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 a common treatment for a child with moderate to severe eczema?

• A. Topical corticosteroids
• B. Oral antibiotics
• C. Frequent saline irrigation
• D. High-calcium diet

Correct answer: A

Rationale: Topical corticosteroids are the correct answer for a child with moderate to severe eczema. These medications are commonly used to reduce inflammation and itching associated with eczema. Oral antibiotics (Choice B) are not typically used in eczema treatment unless there is a secondary bacterial infection. Frequent saline irrigation (Choice C) may aid in wound care but is not a primary treatment for eczema. A high-calcium diet (Choice D) is not a standard treatment for eczema and does not target the underlying inflammatory process that causes eczema symptoms.

3. What is one characteristic that differentiates vitamins from minerals?

• A. Vitamins are organic compounds.
• B. Vitamins provide energy.
• C. Vitamins are considered micronutrients.
• D. Vitamins are essential in small amounts.

Correct answer: A

Rationale: The correct answer is A. Vitamins are organic compounds, containing carbon, which is a key characteristic that differentiates them from minerals. Choice B is incorrect because vitamins do not provide energy; they are not a source of calories. Choice C is incorrect as both vitamins and minerals are considered micronutrients due to being essential in small amounts. Choice D is incorrect because while it is true that vitamins are needed in small amounts, this is not the characteristic that sets them apart from minerals.

4. What should be monitored closely in a child receiving chemotherapy?

• A. Blood glucose levels
• B. White blood cell count
• C. Blood pressure
• D. Heart rate

Correct answer: B

Rationale: The correct answer is B: White blood cell count. During chemotherapy, it is crucial to monitor the white blood cell count closely to detect potential neutropenia (low white blood cell count) and the associated risk of infections. Monitoring blood glucose levels (Choice A) is important for diabetic management and not directly related to chemotherapy. Blood pressure (Choice C) and heart rate (Choice D) are essential vital signs to monitor but are not the primary focus when monitoring a child receiving chemotherapy.

5. What is the primary treatment for a child with acute otitis media?

• A. Antihistamines
• B. Nasal decongestants
• C. Antibiotics
• D. Ear drops

Correct answer: C

Rationale: The correct answer is C: Antibiotics. Antibiotics are the primary treatment for acute otitis media because the condition is often caused by a bacterial infection. Antihistamines (choice A) and nasal decongestants (choice B) are not the primary treatments for acute otitis media as they do not target the bacterial infection. Ear drops (choice D) are not the primary treatment for acute otitis media; antibiotics are required to treat the underlying bacterial cause.
