The correct answer to this question is A, Question the order because it’s too low. A therapeutic theophylline level is 10 to 20 mcg/ml. The mail client is receiving aminophylline at a rate of 0.5 mg/kg/hour. His theophylline level is sub-therapeutic, which means the dose is lower than what is generally prescribed.
Changing the treatment to 0.45 mg/kg/hour would further lower the levels. This is why the order should be questioned because the further reduction of the dosage would not help heal the patient. This question is related to the respiratory system, and it is essential for nurses to know the correct dosages.
A therapeutic theophylline level is 10 to 20 mcg/ml. The client is currently receiving 0.5 mg/kg/hour of aminophylline. Because the clients theophylline level is sub-therapeutic. reducing the dose (which is what the physicians order would do) would be inappropriate. Therefore. the nurse should question the order.
