EMT Practice Test

Answer: D - When a patient has been stung by a jellyfish you can expect to see skin necrosis, cramps, and vomiting. Additionally, you can expect to see itchy red lesions, muscle spasms, nausea, diarrhea, headaches, and excessive sweating. In rare cases you may see cardio-respiratory failure. Jellyfish venom is delivered by barbs called nematocysts that cause an instant reaction when they brush against human skin.
