What should NOT be done when caring for a patient with a marine animal sting?

When caring for a patient with a marine animal sting, applying a cold pack is not an appropriate action. In the case of certain stings, such as those from jellyfish, applying hot water is considered a therapeutic measure because it can help to alleviate pain and inactivate toxins. Cold packs could potentially constrict blood vessels and hinder circulation, which may worsen symptoms.

Monitoring vital signs and providing reassurance are both crucial components of patient care in emergency situations. Vital signs indicate the patient’s current health status and help gauge the severity of the reaction to the sting, while reassurance can help to reduce anxiety and promote a sense of safety for the patient. Therefore, utilizing hot water, monitoring vital signs, and providing reassurance are all appropriate responses in the management of a marine animal sting, making the application of a cold pack the one practice that should be avoided.
