Emergency Medical Technician (EMT) Practice Test

What are some signs and symptoms of cyanide poisoning that may manifest in a patient?

1. bitter almonds?

2. dilated pupils; elevated heart rate; agitation/excitation; unresponsiveness to pain

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

4. cool clammy and pale; poor perfusion from hypotension

The correct answer is: hypoxia at a cellular level; confusion; agitation; burning in mouth; dyspnea

Cyanide poisoning can have varying signs and symptoms depending on the level and duration of exposure. Some of the most common signs and symptoms are hypoxia at a cellular level, confusion, agitation, burning in the mouth, and dyspnea. These can occur because cyanide blocks the cells from being able to use oxygen, leading to a lack of oxygen in the body. The other options are incorrect because while bitter almonds and cool, clammy skin may be associated with cyanide poisoning, they are not reliable indicators. Dilated pupils and elevated heart rate may be present in the initial stages of poisoning, but may not be consistent throughout. Additionally, poor perfusion and hypotension may be seen in severe cases but are not specific to cyanide poisoning and can have other causes.
