The nurse is assisting a client to master the use of a steroid inhaler. The client says, "I don't think I should be using steroids. I see steroids labeled as bad in the news at least once a week." The nurse's response is based on the fact that:
1. The steroid preparations used to treat airway problems are very different from the steroids abused by people reported in the news media. 2. Steroids can be very risky, but the risk is necessary in this client's case. 3. Inhaled steroids are very useful in managing reactive airways, with a fairly good safety profile. 4. Inhaled steroid use is usually short term, so any risk to the client is minimal.
