You Are a Pediatric Nurse Practitioner Working in a Walk-In

You are a pediatric nurse practitioner working in a walk-in clinic. A young mother comes to the clinic with her two-year-old because the child has a swollen arm. While you are taking a history, the mother tells you the child "got stung by a bee yesterday." You examine the child and find only a localized reaction to the bee venom. How would you explain the swelling in the arm to the mother?

A) "Your child got a lot of bee venom and it made the arm puff up."
B) "The swelling is caused by a localized reaction to the bee venom. It will go away in a few days."
C) "The swelling is nothing to worry about."
D) "With this little bit of swelling it should be gone tomorrow."
