What is the best way to remove a stinger from a sting?

Answer: D — Neither A nor B

The best practice for removing a stinger from an insect sting involves using a method that minimizes further venom release and avoids injury to the skin. The recommended technique is to scrape the stinger out with a flat object, such as a credit card or a fingernail, rather than pulling it out with tweezers or fingers. This method helps prevent squeezing the venom sac attached to the stinger, which could release more venom into the skin. Using tweezers can be problematic as it may compress the venom sac and lead to more venom being injected. Similarly, pulling it out with fingers can also increase the risk of squeezing the sac. Therefore, while the choices may suggest various removal methods, the approach that avoids these issues is the most effective and prevents additional discomfort.
