Problem: The client is discharged with controlled blood glucose levels and sufficient health education to manage their diabetes. The client continues care in an outpatient setting. A month later, the client's roommate calls the outpatient Diabetes clinic in a panic: "I'm so worried. They said their heart was beating out of their chest and they felt weak and seemed shaky. Now they seem confused and dizzy, and I'm not sure what to do." What do you think is happening? How would you respond to the roommate on the phone?
