The patient has been exposed to a nerve agent. For which symptoms will the nurse most likely assess?
1. Salivation, involuntary urination, and convulsions
2. Dilated pupils and increased blood pressure and heart rate
3. Pinpoint pupils, decreased blood pressure, and increased heart rate
4. Rapid breathing and cold, clammy skin
Correct Answer: 1
Rationale: Symptoms of nerve gas exposure are related to overstimulation of acetylcholine, and can result in salivation, involuntary urination, and convulsions. The nerve agent blocks acetylcholinesterase. Dilated pupils and increased blood pressure and heart rate are symptoms of sympathetic nervous system stimulation. Pinpoint pupils, decreased blood pressure, and increased heart rate are not symptoms of overstimulation of acetylcholine. Rapid breathing and cold, clammy skin are not symptoms of overstimulation of acetylcholine.
