Emergency Medical Technician (EMT) Intermediate Practice Exam

Which statement regarding hyperglycemic crisis (diabetic coma) is correct?

1. It occurs suddenly within minutes

2. It usually progresses over hours or days

3. It is immediately reversible with insulin

4. It is characterized by rapid onset of symptoms

The correct answer is: It usually progresses over hours or days

A hyperglycemic crisis, commonly referred to as diabetic coma, typically progresses gradually over a period of hours or even days, allowing for the body to adapt and respond to the increasing blood sugar levels. This slow progression is due to the body's gradual depletion of insulin reserves or the gradual onset of insulin resistance, leading to elevated glucose levels and eventual metabolic derangements. In contrast, the other statements do not accurately describe the nature of a hyperglycemic crisis. While symptoms may escalate over time, they do not appear suddenly within minutes, nor does the condition allow for immediate reversibility with insulin. Insulin treatment can significantly aid in managing the crisis, but it may take time to stabilize the patient fully. Additionally, while symptoms can become acute and serious, this condition is not characterized by a rapid onset of symptoms in the way that some other emergencies might be. Understanding the slow progression is crucial for early recognition and intervention.
