Question 2 of 15

Choose the true statement concerning treatment of snakebite:

Snakebites should be treated prophylactically with an antibiotic selected for its Gram-positive activity, particularly against staphylococcal species.

The amount of antivenin given is based on the severity of the symptoms and laboratory data.

The dose of antivenin given to children is weight based.

Of the calculated dose of antivenin, 25–50% should be infiltrated into the local wound of the bite and the rest given intravenously.

Copperhead bites always require antivenin administration.

Snakebites generally do not get infected; therefore, prophylactic antibiotics are not warranted. The amount of antivenin given is primarily a function of the severity of the envenomation. Children (or small adults) should be given proportionately more antivenin because they receive a proportionately greater amount of venom per kilogram of body weight than an adult. Antivenin is given intravenously and never injected into the area of the local wound. The venom of the copperhead is mild and in general no antivenin is needed. However, antivenin is indicated regardless of sensitivity if any symptoms occur after the bite of a coral snake.
