What are the early symptoms of nerve agent poisoning?
Symptoms may start immediately if you have inhaled or been exposed to higher amounts of nerve gas:
- Runny nose and eyes.
- Small pupils or blurry vision.
- Coughing, chest tightness, wheezing, or shortness of breath.
- Nausea and vomiting.
- Abdominal pain or diarrhea.
- Fatigue, headache, or sweating.
- Muscle twitching or a seizure.
What are the symptoms of exposure to a nerve agent like Sarin?
Immediate signs and symptoms of sarin exposure
- Runny nose.
- Watery eyes.
- Small, pinpoint pupils.
- Eye pain.
- Blurred vision.
- Drooling and excessive sweating.
- Cough.
- Chest tightness.
How do nerve agents cause death?
Eventually, victims die either through asphyxiation or cardiac arrest. Unlike street drugs, nerve agents cannot be made in your kitchen or garden shed; they are toxic even in tiny amounts. The chemicals work by disrupting the central nervous system.
What does chemical warfare do to the body?
The most critical effects are paralysis of the respiratory muscles and inhibition of the respiratory center. Ultimately, death results due to respiratory paralysis. If the concentration of the nerve agent is high, death is immediate.
Which of the following signs and symptoms may a patient present with if they have been exposed to sarin select all that apply?
SKIN EXPOSURE: Profuse sweating (diaphoresis) and muscular twitching (fasciculations) at the site of contact, nausea, vomiting (emesis), diarrhea, and weakness (malaise). Severe: Health effects may appear quickly; 2 to 30 minutes post-exposure.
What is the likely cause of death resulting from exposure to this extremely toxic agent?
Death will usually occur as a result of asphyxia due to the inability to control the muscles involved in breathing. Initial symptoms following exposure to sarin are a runny nose, tightness in the chest, and constriction of the pupils.
What does VX do to the body?
VX is a yellowish, odourless and tasteless liquid that disrupts the body’s nervous system to lethal effect. Ten milligrams is enough to kill a person through skin contact although it can also kill through inhalation. One of the women involved in the attack subsequently fell ill too.
How does chemical warfare negatively affect the body?
Choking agents are delivered as gas clouds to the target area, where individuals become casualties through inhalation of the vapour. The toxic agent triggers the immune system, causing fluids to build up in the lungs, which can cause death through asphyxiation or oxygen deficiency if the lungs are badly damaged.
What are the severe signs of nerve agent exposure?
Symptoms of nerve agent exposure. One of the first symptoms of nerve agent exposure is miosis – excessive constriction of the pupil of the eye. Other major symptoms include convulsions, loss of consciousness, excessive fluid secretion of the lungs, high blood pressure, raised heart rate (and then later, lowered heart rate), nausea and vomiting.
Which of the following are severe signs of nerve agent exposure?
Regardless of the route of exposure, nerve agents can cause the following characteristic effects: pinpoint pupils of the eye. excessive production of mucous, tears, saliva and sweat. headache. stomach pain, nausea and vomiting. chest tightness and shortness of breath.
What are signs or symptoms of nerve agents?
Initial symptoms following exposure to nerve agents (like sarin) are a runny nose, tightness in the chest, and constriction of the pupils. Soon after, the victim will have difficulty breathing and will experience nausea and salivation.
How do you treat exposure to nerve agent?
Quickly move away from the area where you think you were exposed.
