A client who was discontinued from using an MAOI 1 week ago has injured his back and is in pain from severe muscle spasms. The client has been prescribed cyclobenzaprine (Flexeril) for the muscle spasms. Which nursing action is the most important?
1. Inform the client to watch for added CNS depression.
2. Warn the client not to operate a motorized vehicle until the effects of the medication are known.
3. Hold the Flexeril and notify the health care provider.
4. Give the Flexeril as prescribed.

3. Hold the Flexeril and notify the health care provider.

Explanation:

Added CNS depression is not the important concern here. Although the client should not operate a motorized vehicle until effects of the drug are known, this is not the most important issue. A potentially fatal hypertensive crisis could occur if cyclobenzaprine is used within 14 days of a MAOI. The health care provider needs to be notified that the client has not been off the MAOI for the required minimum of 14 days before the Flexeril was prescribed.
