A 6-year-old boy whose family recently welcomed home a new baby started wetting the bed. These episodes have occurred at least twice a week for the past 3 months. The nurse practitioner should explain this behavior to the parents as which of the following?

Choice A reason: Occasional accidents in young children may be normal, but recurrent bedwetting at least twice a week for three months, especially in a previously toilet-trained child, suggests a clinical condition rather than a purely normal variation. Choice B reason: Nocturnal enuresis is defined as repeated voiding of urine during sleep in a child aged five years or older, occurring at least twice a week for at least three months. Stressful life events, such as the arrival of a new sibling, can precipitate or exacerbate this condition, making it the most appropriate explanation. Choice C reason: Diabetes mellitus may cause polyuria, but it is usually accompanied by other symptoms such as excessive thirst and weight loss. There is no mention of these symptoms in this case. Choice D reason: Neurogenic bladder involves dysfunction of bladder control due to neurological causes and is uncommon in a healthy child without neurological history or congenital issues.
