Which response should the nurse make?

The correct response is B: Intussusception is more common in infants and toddlers, so your child is at a lower risk. This is the correct answer because intussusception is indeed more common in infants and toddlers, typically occurring between the ages of 3 months and 3 years. Children outside this age range have a lower risk of developing intussusception. Choice A is incorrect because a family history does not necessarily indicate a higher risk in this case. Choice C is incorrect as the risk of intussusception does vary across age groups. Choice D is incorrect as intussusception is not common in school-age children.
