Final answer:
Administering thrombolytic therapy is contraindicated in a client who had an anterior MI and is 1 week postoperative following an open cholecystectomy.
Step-by-step explanation:
Administering thrombolytic therapy is contraindicated in a client who had an anterior MI and is 1 week postoperative following an open cholecystectomy. Thrombolytic therapy is used to dissolve blood clots, and it carries a high risk of bleeding. Since the client is postoperative, her body may still be healing and she may have an increased risk of bleeding. Therefore, administering thrombolytic therapy in this situation could further increase the risk of bleeding, which is contraindicated.
