Final answer:
A nurse should consider bruising and petechiae as possible indications of hemorrhage in a client on anticoagulant therapy with heparin.
Step-by-step explanation:
A nurse monitoring a client undergoing anticoagulant therapy with heparin should be aware of various signs that could indicate hemorrhage. Among the options provided, C) Bruising and petechiae should be identified as the possible indication of hemorrhage. Neither increased blood pressure, decreased heart rate, nor elevated body temperature are direct signs of hemorrhage. In fact, blood pressure may decrease in the event of significant blood loss, and heart rate may increase as the body attempts to compensate.
Bruising and petechiae are direct signs of bleeding problems that can occur under the skin, where small blood vessels may burst or bleed as a result of anticoagulant therapy. Heparin acts by inhibiting clotting factors, which can sometimes lead to excessive bleeding. Therefore, it is critical for nurses to monitor for any signs of bruising, petechiae, or other indications of abnormal bleeding.
