Correct Answer: D

Rationale: The most common treatment for Hirschsprung disease is the surgical removal of the affected section of the bowel. This procedure entails excising the part of the colon that lacks nerve cells crucial for normal bowel function. Daily enemas (Choice A) can offer temporary relief for constipation but do not address the root cause of the condition, which is the absence of nerve cells. A low-fiber diet (Choice B) is not a primary therapy for Hirschsprung disease and may not effectively manage the disorder. A permanent colostomy (Choice C) is typically considered in severe cases where other interventions have failed and is not the standard management approach for Hirschsprung disease.

Correct Answer: B

Rationale: The correct answer is B: Assess for a patent airway. When dealing with a child who has sustained partial thickness burns, the priority is ensuring a patent airway due to the risk of respiratory compromise. Checking the child's skin color (choice A) may be important but is secondary to assessing the airway. While observing for symmetric breathing (choice C) is crucial, assessing the airway takes precedence in this situation. Palpating the child's pulse (choice D) is not the initial priority when managing burns and potential airway compromise.

Correct Answer: A

Rationale: The correct answer is to eat more food when planning to exercise more than usual. Increased physical activity requires more energy, so additional food intake is necessary to compensate for the increased energy expenditure. This helps maintain blood sugar levels within the target range. Choice B is incorrect because the mode of insulin administration does not change based on physical activity; the type and dose of insulin remain the same unless adjusted by a healthcare provider. Choice C is incorrect because insulin timing should not be adjusted solely based on anticipated exercise; consistent timing of insulin doses is crucial for stable blood sugar control. Choice D is incorrect because consuming foods with sugar may lead to unstable blood sugar levels and is not the recommended way to compensate for extra exercise, as it can result in sudden spikes and drops in blood glucose levels, affecting overall diabetes management.

Correct Answer: C

Rationale: The correct answer is to record the best of three attempts when using a peak flow meter. This method provides a more accurate measure of peak expiratory flow. Choice A is incorrect because using the device before taking medication may not reflect the actual peak flow, as medication can affect lung function. Choice B is incorrect as using the device during asthma attacks may not be feasible or safe, as the focus during an attack should be on managing symptoms rather than measuring peak flow. Choice D is incorrect because using the device after eating may not provide an accurate measurement of peak flow, as digestion can affect lung function temporarily.

Correct Answer: C

Rationale: The correct answer is C. Infants may have difficulty regulating glucose and electrolytes due to their immature endocrine systems. This can lead to issues such as hypoglycemia and electrolyte imbalances. Choice A is incorrect because endocrine glands actually begin developing early in gestation, not just in the third trimester. Choice B is incorrect as endocrine glands are not fully functional at birth; they continue to mature and develop after birth. Choice D is incorrect as a child's endocrine system has a significant impact on growth and development through the secretion of hormones that regulate various processes in the body, but it does not specifically address the difficulty in regulating glucose and electrolytes seen in infants.
