A nurse is reviewing the results of electrocardiography monitoring for a client who has atrial fibrillation. Which of the following findings should the nurse expect?

A. Palpate the dorsalis pedis pulse: Assessing distal pulses ensures adequate circulation to the affected extremity. Impaired blood flow can indicate compartment syndrome or vascular compromise, which are serious complications following fracture stabilization. The nurse should also monitor capillary refill, skin temperature, and sensation.

B. Maintain the affected extremity in a dependent position: Keeping the extremity in a dependent position can increase swelling and venous congestion, leading to complications such as compartment syndrome. Elevation is recommended to minimize edema and promote venous return.

C. Wrap sterile gauze on the sharp point of the pins: The pin sites should be left uncovered to allow for proper monitoring of signs of infection or loosening. Instead, pin site care should be performed per facility protocol to reduce infection risk.

D. Adjust the clamps on the fixator frame: Adjusting the external fixator clamps is outside the nurse's scope of practice. Any modifications to the device should be performed by the orthopedic provider to prevent improper alignment and complications.

• Infection: Poor glycemic control, indicated by an elevated hemoglobin A1c of 9.5%, leads to impaired immune function, delayed wound healing, and increased risk of postoperative infections. Chronic hyperglycemia promotes bacterial growth, reduces leukocyte function, and compromises vascular integrity, further predisposing the client to infections.
• Deep vein thrombosis (DVT): Postoperative immobility, increased coagulation, and endothelial injury increase DVT risk. However, BUN of 15 mg/dL is within the normal range and does not indicate dehydration or hemoconcentration, which would contribute to thrombus formation.
• Hypovolemia: Reduced blood volume typically presents with signs such as hypotension, tachycardia, and elevated BUN/creatinine ratio. Preoperative hypertension does not indicate hypovolemia and is more commonly associated with chronic vascular resistance rather than acute fluid loss.
• BUN of 15 mg/dL: A BUN level within the normal range does not suggest an increased risk for DVT or fluid imbalance. It primarily reflects renal function and hydration status, neither of which are significantly altered in this case.
• Preoperative hypertension: While chronic hypertension is a cardiovascular risk factor, it does not indicate hypovolemia, which would present with dehydration-related signs such as orthostatic hypotension, tachycardia, and decreased urine output.
• Hemoglobin A1c: A value of 9.5% indicates poor long-term glycemic control, which impairs immune function and slows wound healing. Elevated glucose levels reduce neutrophil function, impair macrophage activity, and increase oxidative stress, all of which contribute to a heightened infection risk.
