1. What does a positive correlation between two variables indicate?

• A. One variable causes the other.
• B. Both variables move in the same direction.
• C. Both variables move in opposite directions.
• D. There is no relationship between the variables.

Correct answer: B

Rationale: A positive correlation between two variables indicates that they move in the same direction. This means that as one variable increases (or decreases), the other variable also increases (or decreases). Choice A is incorrect because correlation does not imply causation; it only shows a relationship between variables. Choice C is incorrect as it describes a negative correlation where variables move in opposite directions. Choice D is incorrect as a positive correlation implies a relationship between the variables.

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. 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.

4. How should a healthcare professional manage a child with scabies?

• A. Use topical permethrin cream
• B. Administer oral antibiotics
• C. Apply topical antifungals
• D. Provide supportive care only

Correct answer: A

Rationale: Corrected Rationale: Topical permethrin cream is the appropriate treatment for scabies as it effectively kills the mites causing the infestation. Oral antibiotics are not indicated for scabies as it is not a bacterial infection. Topical antifungals are used to treat fungal infections, not scabies. Providing supportive care only would not address the underlying cause of scabies, which is the mite infestation.

5. Which of the following is an example of a macronutrient?

• A. Vitamin C
• B. Iron
• C. Calcium
• D. Fiber

Correct answer: D

Rationale: The correct answer is D: Fiber. Macronutrients are nutrients required by the body in larger amounts, and they include carbohydrates, proteins, and fats. Fiber is a type of carbohydrate that falls under this category. Vitamin C (choice A) is a water-soluble vitamin, Iron (choice B) is a mineral, and Calcium (choice C) is also a mineral, not a macronutrient. Therefore, Fiber is the only macronutrient listed in the choices.
