This week’s free board review question…
A 13-year-old boy presents to you with a bite to his fingers after hunting for snakes with his friend (see Figure 1).
He was bitten by the snake shown in Figure 2, which is a black-tail rattlesnake.
He states that he had immediate pain and the finger has become progressively swollen in the 30 minutes since the bite. He also complains of pain in his forearm. The digit is ecchymotic with petechiae on the back of the hand and the forearm.
He describes some nausea, and he has vomited once. He has no laboratory abnormalities. He has no systemic symptoms, but he later required antivenin because of progressive swelling.
Of the following, this is an example of what level of severity of a possible pit viper envenomation?
grade 0 (minimal)
grade 1 (minimal)
grade 2 (moderate)
grade 3 (severe)
