Introduction
A bite can look trivial while the exposure remains time critical.
A bite can look trivial while the exposure remains time-critical. Rabies virus may replicate near the wound, then travel backward along peripheral nerves toward the spinal cord and brain. After central nervous system entry, it spreads rapidly and cannot be reliably intercepted by immune globulin or vaccine. Post-exposure prophylaxis therefore prevents neuroinvasion; it is not a treatment for symptomatic rabies, which is almost invariably fatal. The first nursing action is thorough soap-and-water irrigation, not waiting for animal testing or biologics. Whether PEP is indicated depends on the animal, the type of contact, the wound or mucosal exposure, and whether the animal is available for observation or testing. In the United States, the state or local health department and an authorized prescriber guide that decision. Within state law and employer policy, the LVN/LPN may collect exposure data, perform immediate wound care, administer ordered vaccine, observe for reactions, reinforce teaching, and coordinate follow-up under appropriate supervision. Independent exposure-risk determination and wound infiltration with rabies immune globulin are not typical independent LVN/LPN functions.
