Emergency Medical Technician (EMT) Practice Test

What are common symptoms seen in individuals affected by depressants?

1. hypoxia at a cellular level; confusion; agitation; burning in mouth; dyspnea

2. modified anaphylaxis

3. decrease hr, bp, rr; depress mental status; cool clammy and pale bc poor perfusion from hypotension

4. dehydration; some insulin is being produced so some glucose is getting to cells therefore there is no large ketone buildup; NO Kussmaul's respirations or fruity breath

The correct answer is: decrease hr, bp, rr; depress mental status; cool clammy and pale bc poor perfusion from hypotension

The correct answer identifies several physiological effects commonly associated with depressants. Depressants, such as alcohol or benzodiazepines, act on the central nervous system to slow down brain activity. This leads to a decrease in heart rate, blood pressure, and respiratory rate, which can result in a significantly depressed mental status. Additionally, as the body’s circulatory system becomes compromised due to hypotension, individuals may exhibit signs of poor perfusion, such as cool, clammy, and pale skin. This answer highlights the critical aspects of how depressants affect bodily functions and the importance of recognizing these symptoms in emergency situations. Understanding these signs can be crucial for EMTs in assessing a patient's condition and determining the appropriate course of action.
