An adult client with asthma is placed on theophylline therapy. On theophylline monitoring, the client’s serum theophylline level is determined at 50 mcg/dL. Based on the finding, which of the following signs should the nurse expect to see from the client?
  1. The client shows no signs of respiratory distress
  2. The client is observed with tremors and complains of abdominal pain
  3. The client is observed with labored and rapid breathing
  4. The client showing signs of irritability caused by constipation
Explanation
Answer: B - The client’s theophylline level is greater than the therapeutic range. The nurse should expect the client to demonstrate tremors, abdominal pain, irritability, nausea, and diarrhea resulting from theophylline toxicity. The normal range of serum theophylline is between 10 and 20 mcg/dL.
