When an increase in exercise is accompanied by a decrease in body weight, it is an example of what?
- A. variable effect
- B. positive correlation
- C. negative correlation
- D. randomization effect
Correct Answer: C
Rationale: When an increase in exercise is accompanied by a decrease in body weight, it demonstrates a negative correlation. This means that as one variable (exercise) increases, the other variable (body weight) decreases. Choice A, 'variable effect,' is vague and does not accurately describe the relationship between exercise and body weight. Choice B, 'positive correlation,' is incorrect because in a positive correlation, both variables would increase or decrease together. Choice D, 'randomization effect,' is unrelated to the scenario described.

What should be included in the medical management of a sickle cell crisis?
- A. Information for parents on home care
- B. Adequate hydration and pain management
- C. Pain management and iron supplements
- D. Adequate oxygenation and factor VIII
Correct Answer: B
Rationale: The correct answer is B: Adequate hydration and pain management. During a sickle cell crisis, it is essential to provide hydration to prevent vaso-occlusive events and manage pain effectively with analgesics. Adequate hydration helps maintain blood flow and prevent further sickling of red blood cells. Pain management is crucial to alleviate the severe pain associated with sickle cell crises. Options A, C, and D are incorrect. Providing information for parents on home care (Option A) may be important for ongoing management but is not specific to an acute crisis. Iron supplements (Option C) are not typically indicated during a sickle cell crisis. Adequate oxygenation and factor VIII (Option D) are not primary interventions for managing a sickle cell crisis; instead, oxygen therapy may be considered in severe cases, and factor VIII is not a standard treatment for sickle cell disease.
How should a healthcare provider assist in the management of a child with type 1 diabetes?
- A. Provide high-carbohydrate snacks
- B. Schedule frequent blood glucose tests
- C. Increase dietary fat intake
- D. Encourage a high-protein diet
Correct Answer: B
Rationale: For the management of type 1 diabetes in a child, scheduling frequent blood glucose tests is essential. These tests help in monitoring blood sugar levels, adjusting insulin doses, and ensuring proper glucose control. Choices A, C, and D are incorrect. Providing high-carbohydrate snacks can lead to blood sugar spikes, increasing dietary fat intake is not recommended, and encouraging a high-protein diet is not a standard recommendation for managing type 1 diabetes in children.
What is a key sign of meningitis in an infant?
- A. Increased appetite
- B. Bulging fontanel
- C. Decreased respiratory rate
- D. Elevated blood pressure
Correct Answer: B
Rationale: A bulging fontanel is a key sign of meningitis in infants, indicating increased intracranial pressure due to inflammation of the meninges. This can lead to the fontanel bulging. Choices A, C, and D are incorrect. Increased appetite is not typically associated with meningitis in infants; instead, they may have poor feeding. A decreased respiratory rate is not a common sign of meningitis in infants. Elevated blood pressure is also not a typical finding in infants with meningitis.
What is the primary goal in managing a child with asthma?
- A. Prevent triggering asthma attacks
- B. Avoid triggering asthma attacks
- C. Administer corticosteroids
- D. Increase physical activity
Correct Answer: B
Rationale: The primary goal in managing a child with asthma is to avoid triggering asthma attacks. This involves managing allergens, ensuring proper medication use, and creating an asthma action plan. Choice A is incorrect because the goal is to avoid triggering asthma attacks, not necessarily to prevent recurrent infections. Choice C is incorrect as corticosteroids are a treatment option but not the primary goal of asthma management. Choice D is incorrect because although physical activity is important, the primary goal is to prevent asthma attacks and manage symptoms effectively.
