A nurse is assessing a client who is in skeletal traction for a fractured left tibia. The nurse should identify that which of the following findings indicates altered tissue perfusion of the affected extremity?

A. Faint pedal pulse of left leg: A faint pedal pulse indicates poor circulation and is a clear sign of altered tissue perfusion. It suggests that the blood flow to the affected extremity may be compromised, warranting immediate assessment and intervention. B. Pain with movement of the left great toe: While pain may indicate an issue, it does not specifically indicate altered tissue perfusion. Pain can result from various causes, including injury or inflammation, but it is not a direct measure of blood flow. C. Purulent drainage at the pin site: Purulent drainage suggests infection rather than altered perfusion. While infections can affect tissue health, this finding does not directly indicate compromised blood flow to the extremity. D. Warm skin temperature distal to pin site: Warm skin typically suggests adequate perfusion, as warmth can indicate good blood flow. In contrast, coolness or coldness would be a more concerning sign of altered perfusion.
