Which intervention is NOT appropriate for a client with a snakebite?

Applying a tourniquet to stop venom spread is not an appropriate intervention for a client with a snakebite. The rationale behind this is based on the understanding of how venom acts and the physiological impact of using a tourniquet. A tourniquet can create additional complications by cutting off blood flow entirely, which may lead to tissue damage and necrosis. When treating a snakebite, the priority is to ensure the affected limb is immobilized and kept at or below heart level to slow the spread of venom, rather than attempting to completely obstruct blood flow with a tourniquet.

The other interventions mentioned, such as removing rings and watches from the affected limb, are appropriate as they prevent constriction as swelling occurs. Administering tetanus prophylaxis is also standard practice if the patient's vaccination status is not up to date, considering the increased risk of infection. Immobilizing the arm at heart level further aids in managing the situation by minimizing movement and reducing venous return, which can assist in controlling venom spread.
