A nurse is caring for a 24-year-old female client in the post-operative unit following a horseback riding accident. Exhibits Which of the following assessment findings should the nurse attend to right away?

Choice B rationale: Capillary refill time of 6 seconds is significantly delayed and indicates poor peripheral perfusion. This finding suggests that the client may be experiencing decreased cardiac output or hypovolemia, which requires immediate attention to improve circulation and oxygen delivery to tissues. Choice C rationale: Blood pressure of 90/79 mmHg with a pulse pressure of less than 40 mmHg is a critical finding. The narrow pulse pressure and hypotension indicate potential hypovolemia or shock, which must be addressed urgently to stabilize the client's hemodynamic status. Choice D rationale: The client’s lack of urine output from the indwelling catheter is concerning and indicates potential kidney dysfunction or decreased renal perfusion. Immediate intervention is necessary to assess and manage potential underlying causes, such as hypovolemia or renal injury. Choice A rationale: Oxygen saturation of 100% on 40% oxygen is not an immediate concern. While it is important to continue monitoring oxygen levels, the client is currently receiving adequate oxygenation.
