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. How should a caregiver manage a child with a newly diagnosed hearing impairment?

• A. Increase the volume of all auditory stimuli
• B. Refer for audiologic evaluation and intervention
• C. Avoid using any assistive devices
• D. Encourage frequent use of headphones

Correct answer: B

Rationale: When a child is newly diagnosed with a hearing impairment, it is essential to refer them for audiologic evaluation and intervention. This step is crucial to accurately assess the extent of the impairment, determine appropriate interventions, and support the child's communication and development. Increasing the volume of all auditory stimuli (choice A) is not a recommended approach as it may not address the specific needs of the child and could potentially cause discomfort. Avoiding the use of assistive devices (choice C) can hinder the child's ability to communicate effectively. Encouraging frequent use of headphones (choice D) is also not advisable as it may not be suitable for managing hearing impairments and could potentially worsen the condition.

3. What should be assessed first in a child with suspected head trauma?

• A. Response to verbal stimuli
• B. Pupillary reaction
• C. Skin color
• D. Heart rate

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.

4. What is an important aspect of the care plan for a child with eczema?

• A. Use of steroid creams
• B. Frequent antibiotic therapy
• C. High-protein diet
• D. Daily baths in hot water

Correct answer: A

Rationale: The correct answer is A: Use of steroid creams. Steroid creams are commonly used in the management of eczema to reduce inflammation and itching, thus improving the skin condition and comfort of the child. Choice B, frequent antibiotic therapy, is incorrect as antibiotics are not typically used to treat eczema unless there is a secondary bacterial infection. Choice C, a high-protein diet, is not a specific recommendation for eczema treatment. Choice D, daily baths in hot water, is not recommended for eczema care as hot water can exacerbate the condition by drying out the skin.

5. 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.
