The nurse is caring for a client who was camping overnight. The client is vomiting and has severe pain in the left foot Blood pressure is 90/60, and the left lower leg is swollen and red. For which condition will the nurse assess as the priority?

A. The client’s swollen, red, painful foot, hypotension (90/60), and vomiting are classic signs of a venomous snakebite, which can cause systemic toxicity, hypotension, coagulopathy, and tissue necrosis. Snakebite is a life-threatening emergency that requires immediate assessment, stabilization, and possible administration of antivenom, making it the priority condition. B. Heat exhaustion presents with weakness, nausea, headache, and mild hypotension, but the localized swelling and redness in the leg are not consistent with heat exhaustion. C. Altitude sickness typically develops at higher elevations and manifests as headache, nausea, dizziness, and fatigue, not a localized extremity injury with hypotension. D. Brown recluse spider bites can cause localized pain, redness, and necrosis, but systemic symptoms such as hypotension and vomiting are less common, making snakebite the higher-priority assessment.
