Why is it important to apply pressure and immobilize the area when treating for a snake bite?

Applying pressure and immobilizing the area is crucial when treating a snake bite because it effectively slows the absorption of venom into the bloodstream. When a snake bites, venom can quickly enter the circulation and cause systemic effects. By immobilizing the bitten limb and applying gentle pressure, you can help localize the venom, preventing it from spreading rapidly throughout the body. This initial treatment is essential in managing the effects of the venom until medical help can be reached, as it can potentially improve the outcome for the victim.

The other options, while they may have some relevance to the treatment of wounds in general, do not directly address the primary concern with snake bites. Therefore, the focus on slowing the absorption of the venom is the most pertinent reason for these actions in the context of a snake bite.
