Correct Answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. This procedure reveals the absence of ganglion cells in the affected bowel segment, which is a hallmark of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for diagnosing Hirschsprung disease due to the risk of not accurately reaching the affected segment. Multiple saline enemas (Choice C) are not used to confirm the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a standard diagnostic procedure for Hirschsprung disease and does not provide the necessary information to confirm the absence of ganglion cells in the affected bowel segment.

Correct Answer: B

Rationale: The most appropriate response for the nurse in this situation is to ask for more specific information related to the developmental delays. By seeking additional details, the nurse can better understand the situation, offer appropriate support, and provide guidance tailored to the child's specific needs. Praising the parent or encouraging the plan without understanding the full context may not be beneficial. Advising the parent to have the healthcare provider help choose a program assumes the parent has not already involved the healthcare provider, which may not be the case. Explaining that the developmental delays could disappear is not appropriate as it may give false hope or minimize the parent's concerns.

Correct Answer: B

Rationale: When managing a child with partial thickness burns over the upper body areas, the priority action during the primary survey is to assess for a patent airway. This step is crucial as burns in this region can lead to airway compromise, potentially causing rapid deterioration in the child's condition. Checking for a patent airway ensures that the child can breathe adequately, which is essential for oxygenation and ventilation. Inspecting the child's skin color (Choice A) is an important assessment but should follow ensuring a patent airway. Observing for symmetric breathing (Choice C) is relevant, but the immediate focus should be on securing the airway. Palpating the child's pulse (Choice D) is also a vital assessment, but in this scenario, the priority is to assess and maintain a clear airway to support respiratory function and oxygen delivery.

Correct Answer: B

Rationale: When a limb is protruding from the vagina during active labor, the appropriate management includes positioning the mother in a head-down position with her hips elevated. This position helps relieve pressure on the umbilical cord, reducing the risk of compromising fetal blood flow and oxygenation. Administering oxygen is essential to maintain oxygenation levels for both the mother and the fetus. Providing transport to a healthcare facility equipped to manage this obstetric emergency is crucial for ensuring a safe delivery. Choice A is incorrect because a semi-Fowler's position does not effectively relieve pressure on the umbilical cord. Choice C is incorrect as applying traction to the protruding limb can lead to injury or complications for both the mother and the fetus. Choice D is incorrect because attempting to manipulate the limb without proper positioning and preparation can worsen the situation and increase risks during delivery.

Correct Answer: A

Rationale: Monitoring liver function tests regularly is crucial when a child with JIA is on methotrexate due to the potential hepatotoxicity associated with this medication. Methotrexate can lead to liver damage, hence monitoring helps in early detection and intervention. Encouraging regular exercise (Choice B) is generally good for children with JIA to maintain joint mobility and muscle strength, but it is not directly related to methotrexate therapy. Providing high-calorie snacks (Choice C) is not a priority consideration for a child on methotrexate. Encouraging frequent handwashing (Choice D) is important for infection control, but it is not specifically associated with methotrexate therapy in a child with JIA.
