A nurse is assisting in the care of a client who is in the emergency department (ED) following a ski accident. Which of the following actions should the nurse take? Select all that apply.

A. Restrict fluid intake: There is no indication of fluid overload or conditions requiring fluid restriction. Limiting fluids could worsen perfusion and hydration status, so this action is not appropriate. B. Prepare to administer an antibiotic: The client has signs of infection risk at the open fracture site, including swelling, taut tissue, and increasing pain. Early administration of antibiotics is critical to prevent osteomyelitis and systemic infection. C. Prepare to obtain a wound culture: The presence of swelling, taut tissue, and new neurological symptoms in the affected limb suggests possible infection or compartment syndrome. Obtaining a wound culture helps guide targeted antimicrobial therapy. D. Initiate supplemental oxygen: The client reports difficulty catching their breath, indicating potential hypoxia or early respiratory compromise. Administering supplemental oxygen supports oxygenation and prevents further tissue hypoxia. E. Administer an analgesic: Severe pain (10/10) requires prompt analgesia to reduce discomfort and physiological stress. Adequate pain management is essential, especially in the context of worsening neurovascular status and potential complications.
