I know there has to be more to this story. I really hope that nurse documented everything she saw and did.
Early on in my school nurse career I went to a workshop put on by the local children's hospital. I asked the respiratory therapist if all values were normal (no wheeze, no cough, good PSO2) and the only symptom the student was complaining of was chest tightness, should I withhold the inhaler? Nope, the answer was never withhold the inhaler....ever. Words I still live by: "You don't want to be that nurse, the one who took the inhaler away."
