Yes we did. Because, we, as the parents, "know" our kid. He had the same cold the other 3 had. A little cough, a little runny nose, he was running around playing, same huge appetite. Looked fine, felt fine, acted fine, didn't complain. It's a cold, it will pass. Eh...so...we were wrong. So yes, "Dr. Mom" isn't always right.
...and, as has been pointed out before, no one, including the OP know what her son said to the nurse. One thing we do know is that he was at the nurse twice in a week's time complaining of URI symptoms, and something he said prompted the nurse to look in his throat. She saw what were signs of strep and referred him for medical clearance. That was her job. The OP isn't the only parent in the school, the OP's son isn't the only child. It is the nurse's job to protect the student body, not just cater to one kid and his mother. ...and if a 16 year old kid would come to the nurse for a cough drop, I am pretty sure he would be back again with another "complaint."
No one was "damaged" a 16 year old got a strep swab. Big deal. My 4 year old had one...she didn't cry, I am pretty sure a 16 year old can handle it.
Like I said before, in healthcare people hear what the want to hear and hear the tone they want to hear. I will give you an example, a patient who has cancer and declined traditional treatment, instead, opting for "natural" treatment. Her CT showed some lesions on her liver. She was told, "it could be metastatic cancer, or they could be cysts, you will need further testing to determine that." 3 months later comes back with abdominal pain and has told her cancer has spread to her liver. Her response? "That's impossible, because 3 months ago I was told I only had cysts in my liver."
The OP was annoyed and frustrated that she had to pick her son up from school, she was annoyed that he was missing class and the she may, potentially, have had to take off work to take him to a doctor's appointment she deemed unnecessary. In her anger and frustration she may have projected her attitude and feelings onto the nurse and she may has missed the phrase, "he might."
Again, we don't know. We know what the OP heard. We know what her son told her.
...but what we do know is that no one was "damaged." The kid got a medical screening, and got out of class (which was probably his goal, anyway)
HAPPY NURSES WEEK!
...because sometimes even combat pay wouldn't be enough.
