A Pediatric Nurse Is Educating a 6-Year-Old and the Mother

A pediatric nurse is educating a 6-year-old and the mother on the use of a metered-dose inhaler (MDI) with a spacer. The mother asks what the spacer is for. The nurse responds:

A) "Without the spacer, most of the medication does not get into the lungs because the heavier particles fall out into the throat."
B) "It can be difficult to properly coordinate pressing the canister and inhaling so the medication falls into the mouth instead of getting to the lungs."
C) "The spacer holds the medication during inhalation, so your child will not have to worry about coordination."
D) "The spacer is automatically activated when your child inhales, making it a lot easier to get the medication into the lungs."
E) "The spacer vaporizes the medication so your child can inhale it. More medication gets directly into the lungs."
