Upon assessment of a patient in the recovery room following knee arthroplasty, the nurse notes decreased pedal pulses. What is the most appropriate initial action for the nurse to take?

Choice A rationale The initial nursing action must be assessment to determine the significance of the finding. Decreased pulses can be a sign of vascular compromise, but they must be compared to the preoperative baseline. Some patients have naturally faint pulses or peripheral vascular disease present before surgery. Normal capillary refill is typically < 3 seconds. By comparing current data to the baseline, the nurse can determine if this is a new, acute change or a pre-existing condition before escalating care. Choice B rationale Elevating the leg significantly above the heart level is contraindicated if arterial flow is already compromised. While slight elevation helps with venous return and reduces edema, extreme elevation can further decrease arterial perfusion pressure to the distal extremity. This could worsen ischemia if the decreased pulses are due to arterial occlusion or compartment syndrome. The nurse should keep the limb at a neutral level or slightly elevated until the circulatory status is fully clarified through assessment. Choice C rationale Contacting the surgeon is an appropriate action, but it is not the first action. The nurse must first gather all necessary assessment data, including skin temperature, color, sensation, and motor function, to provide a comprehensive SBAR report. Reporting a single finding without context or comparison to baseline data is inefficient. The nurse should verify the findings and check for other signs of neurovascular impairment, such as paresthesia or coolness, before notifying the surgical team of a potential complication. Choice D rationale Activating the emergency response team is premature unless the patient is showing signs of immediate life-threatening instability or total limb ischemia with absence of pulses. Decreased pulses require prompt attention, but the nurse must first perform a focused assessment to determine if a Doppler study is needed. Jumping to an emergency code without preliminary assessment can distract resources from other patients. The nurse should follow the clinical hierarchy of assessment, verification, and then appropriate notification based on the severity.
