Correct Answer: C

Rationale: Peripheral edema is often considered the last sign of heart failure in infants and children. It indicates significant fluid retention and circulatory compromise. Tachypnea (increased respiratory rate) and tachycardia (increased heart rate) are early signs of heart failure due to inadequate cardiac output. Periorbital edema, while a sign of excess fluid, typically occurs earlier in the progression of heart failure compared to peripheral edema.

Correct Answer: A

Rationale: Applying a warm compress to the affected ear is a recommended home remedy for earaches as it can help reduce pain and discomfort. The warmth can also help improve circulation and promote drainage if there is fluid buildup. Giving a cold drink (Choice B) is not typically beneficial for earaches and fever. Administering acetaminophen (Choice C) can help reduce fever and alleviate pain, but addressing the earache directly with a warm compress is a more targeted approach. Taking the child to the emergency department (Choice D) is not necessary for a common earache unless there are severe symptoms or complications present.

Correct Answer: B

Rationale: Choice B is the correct answer because it accurately states that White, non-Hispanic children are more likely to be in very good or excellent health compared to African American and Hispanic children. This reflects a disparity in health outcomes among different racial groups. Choices A, C, and D are incorrect. Choice A is unrelated to the impact of common barriers to health care on families. Choice C talks about overweight children but does not address access to health care. Choice D discusses the impact of the overall health care plan on working families but does not specifically address the disparity in health status among different racial groups.

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.

Correct Answer: C

Rationale: The correct answer is C. In fluid replacement therapy for burns, it is crucial to administer most of the volume during the first 8 hours to prevent shock and maintain perfusion. This rapid administration is essential to stabilize the child's condition. Choices A and B are incorrect because the initial fluid replacement in burns typically involves administering crystalloids, not colloids, and the fluid replacement is generally calculated based on the extent of the burn injury, not the type of burn. Choice D is incorrect as monitoring hourly urine output to achieve less than 1 mL/kg/hr is not recommended in burn patients; instead, urine output should be monitored to achieve 1-2 mL/kg/hr in children to ensure adequate renal perfusion.
