As the home health nurse, you visit with Mr. Jonas Maxwell weekly to assess his pulmonary status and his adherence to his medication regimen. Jonas has end-stage COPD. He was diagnosed with the disease many years ago and his pulmonary status has deteriorated slowly during the past few years. Despite his health care provider’s recommendation to change to another medication, Jonas insists that theophylline (Theo-Dur) is the only medication that helps him to breathe. He also uses several MDIs with spacers several times per day.

1. What symptoms would you expect to observe in Jonas if he is experiencing early signs of toxicity?

2. Create a list of things to avoid for an individual who is receiving theophylline therapy.

3. In your own words, how would you describe the function of the spacer used with Jonas’s MDI?
