While I'm here...
Twelve-year-old girl with a fever of 102; headache; stomachache; miserable. A careful exam turns up nothing, so in this part of the country at this time of year we do a test for Lyme disease. Draw the blood; comfort the kid. Review symptomatic care with tylenol and ibuprofen. Discuss how long the blood test will take and make arrangements to call once the results are back; etc.
Finally, on the way out the door, the mother says,
Oh! While we're here, can I have a note saying she's ok to play field hockey?What? The kids is sick as a dog and you want a note for sports?
This way I don't have to come back and bug you next week.You know what? As a busy parent, I understood. And I gave her the note -- undated. She can fill in the date once the kid is better. (The Lyme test was negative, and she was good to go within the week.)
