11

after obtaining a peak expiratory flow reading of 200mL, you administered one bronchodilator treatment to a 21 year old woman with an acute epsode of expiratory wheezing, The next peak flow reading is 400 mL. you should:
A) recognize that the PT'S condition has improved
B) give another bronchodilator treatment and reassess

A

12

you are attempting to intubate a 5 year old girl when you note that her heart rate has fallen from 120 beats per min to 80 beats per min. A patent IV line has been established. the MOST appropiate action is to:
