Correct Answer: B

Rationale: In the scenario described, the priority is to relieve pressure from the umbilical cord protruding from the vaginal opening by gently pushing it back inside using your gloved fingers. This action helps prevent cord compression, maintains blood flow to the fetus, and ensures fetal oxygenation. Massaging the uterus (Choice A) is not appropriate in this situation as it can potentially worsen the cord compression. Placing the mother on her left side and providing rapid transport (Choice C) can be considered after relieving the pressure on the cord. Elevating the mother's lower extremities and providing immediate transport (Choice D) is not the correct approach when dealing with a visible umbilical cord; instead, the focus should be on relieving pressure from the cord to prevent fetal compromise.

Correct Answer: B

Rationale: The correct answer is B: Epiphysis. Bone growth primarily occurs in the epiphysis, which is the area where growth plates are located. The epiphysis is responsible for longitudinal bone growth. Choice A, 'Growth plate,' is incorrect as it does not specify the exact area where bone growth primarily occurs. Choice C, 'Physis,' refers to the same structure as a growth plate, but the term 'epiphysis' is more specific to bone growth. Choice D, 'Metaphysis,' is incorrect as it is the area of the bone where the epiphysis meets the diaphysis, not the primary site of bone growth.

Correct Answer: B

Rationale: The correct answer is monitoring fluid balance. In a child with diabetes insipidus, the primary concern is excessive urination and fluid loss, which can lead to dehydration. Monitoring fluid balance is crucial to prevent dehydration and maintain electrolyte balance. Administering insulin (Choice A) is not indicated in diabetes insipidus, as this condition is not related to insulin deficiency. Administering diuretics (Choice C) should be avoided as it can exacerbate fluid loss in a child already at risk for dehydration. While monitoring vital signs (Choice D) is important, the priority intervention in this situation is monitoring fluid balance to prevent complications associated with dehydration.

Correct Answer: B

Rationale: Establishing a bedtime routine is the most appropriate suggestion for a child experiencing night terrors. Consistent bedtime routines help create a sense of security and predictability, reducing the likelihood of night terrors. Encouraging the child to talk about the dream (Choice A) may not be effective as night terrors occur during non-REM sleep, and the child may not remember the dreams. Allowing the child to sleep with the parents (Choice C) can reinforce dependency and may not address the underlying causes of night terrors. Waking the child during the night (Choice D) can disrupt their sleep cycle and worsen the occurrence of night terrors.
