Correct Answer: B

Rationale: Choice B is the correct answer as white, non-Hispanic children are more likely to be in very good or excellent health compared to African American and Hispanic children. This is an important disparity in health outcomes that may be influenced by various social determinants. Choices A, C, and D are incorrect because they do not accurately describe how certain families are affected by common barriers to health care. Choice A discusses the declining percentage of children in low-income families, which is not directly related to barriers to health care. Choice C talks about overweight children and the increase in African American females but does not address access to health care. Choice D discusses the impact of health care plans on working families but does not specifically address barriers to health care access for families.

Correct Answer: D

Rationale: The correct answer is D: Severe coughing spells. Pertussis, also known as whooping cough, typically presents with severe coughing spells that can be followed by a characteristic 'whoop' sound. These coughing fits can be intense and prolonged, often causing the child to gasp for air between coughs. Option A, dry hacking cough, is a common symptom of other respiratory conditions like bronchitis. Option B, inspiratory stridor, is more commonly associated with conditions like croup. Option C, nasal congestion, is not a typical symptom of pertussis.

Correct Answer: B

Rationale: When parents of a toddler request to be present during a procedure, it is crucial to conduct an individual assessment of the parents. This assessment helps healthcare professionals understand the parents' ability to cope with the procedure, provide support to their child, and ensure a safe and comfortable environment for all involved. Choice A, the type of procedure to be performed, while important, is not the most critical factor in this scenario. Choice C, whether the toddler wants the parents present, is significant but secondary to assessing the parents themselves. Choice D, probable reaction to the toddler's response to pain, is important but focuses more on the child's reaction rather than the parents' capacity to provide appropriate support.

Correct Answer: A

Rationale: Giving prednisone with food helps prevent gastrointestinal upset. Therefore, the correct statement is that the drug should be given after the child eats something, not before. Watching for infections is important due to prednisone's immunosuppressive effects, making choice B correct. Choice C is accurate because prednisone should be tapered off gradually to prevent withdrawal symptoms. Weight gain is a common side effect of prednisone, so choice D is also correct. The incorrect statement is choice A, as prednisone should be administered after a meal.

Correct Answer: A

Rationale: The correct answer is to advise the parents to avoid exposure to allergens. Asthma attacks are often triggered by allergens such as dust mites, pollen, pet dander, and mold. By minimizing the child's exposure to these triggers, the likelihood of asthma attacks can be reduced. Encouraging regular exercise is beneficial for overall health but may not directly prevent asthma attacks. Providing a high-protein diet and increasing fluid intake are important for general well-being but do not specifically address asthma prevention.
