1. What is a common sign of an allergic reaction in children?
- A. Persistent cough
- B. Skin rash or hives
- C. Increased appetite
- D. Low-grade fever
Correct answer: B
Rationale: Skin rash or hives are common signs of an allergic reaction in children, often following exposure to allergens. While a persistent cough can occur in some cases, it is not typically a primary sign of an allergic reaction. Increased appetite is unrelated to allergic reactions. A low-grade fever is not a common sign of an allergic reaction but can be present in other conditions like infections.
2. What is a common sign of dehydration in a child with diarrhea?
- A. Decreased urine output
- B. Increased appetite
- C. Warm, dry skin
- D. Elevated blood pressure
Correct answer: A
Rationale: The correct answer is A: Decreased urine output. When a child with diarrhea is dehydrated, they may have decreased urine output, indicating that their body is conserving fluids. This sign highlights the importance of fluid replacement to prevent worsening dehydration. Choices B, C, and D are incorrect. Increased appetite is not typically associated with dehydration but can be seen in other conditions. Warm, dry skin may be a sign of fever or other skin conditions, not specifically dehydration. Elevated blood pressure is not a common sign of dehydration in a child with diarrhea.
3. Why would a person who eats a bowl of oatmeal for breakfast every day most likely be making a food choice based on ___?
- A. habit
- B. availability
- C. body image
- D. environmental concerns
Correct answer: A
Rationale: The correct answer is A: habit. Eating the same food regularly often stems from habit, which is a behavior that is repeated regularly and tends to occur subconsciously. Choice B, availability, is incorrect as it refers to the accessibility of a particular food rather than the frequency of consumption. Choice C, body image, is also incorrect as this term relates to how one perceives their own body rather than their food choices. Choice D, environmental concerns, is unrelated to the scenario provided, which is about the frequency of choosing oatmeal for breakfast.
4. What role do fats play in the human body?
- A. They provide a concentrated source of energy.
- B. They are the building blocks of enzymes and hormones.
- C. They are essential for brain function and development.
- D. They aid in the digestion of food.
Correct answer: D
Rationale: Fats play various essential roles in the human body, one of which is aiding in the digestion of food. While fats do provide a concentrated source of energy, the primary source is carbohydrates. Proteins are the building blocks of enzymes and hormones, not fats. Essential fatty acids found in fats are vital for brain function and development, but this is not the primary role of fats in the body.
5. What is one benefit of using controls in an experiment?
- A. The size of the groups does not matter.
- B. The subjects are unaware of the experiment's details.
- C. The subjects who are treated are balanced against the placebos.
- D. The subjects are similar in all respects except for the treatment being tested.
Correct answer: D
Rationale: The correct answer is D. Controls in an experiment ensure that the subjects are similar in all respects except for the treatment being tested. This allows for a fair comparison between the treatment group and the control group. Choice A is incorrect because the size of the groups is not the primary benefit of using controls. Choice B is incorrect as blinding, not controls, refers to subjects not knowing about the experiment. Choice C is incorrect as it pertains more to randomization than the use of controls.
