In evaluating the effectiveness of a postoperative client's intermittent pneumatic compression devices, which assessment is most important for the nurse to complete?

The correct answer is choice C. Observe both lower extremities for redness and swelling. Choice A rationale: Palpating all peripheral pulse points for volume and strength is important for assessing circulation, but it does not directly evaluate the effectiveness of intermittent pneumatic compression (IPC) devices. IPC devices are primarily used to prevent deep vein thrombosis (DVT) and improve venous return, so monitoring for signs of DVT is more relevant. Choice B rationale: Monitoring the amount of drainage from the client’s incision is crucial for assessing wound healing and detecting potential infections, but it is not related to the effectiveness of IPC devices. Choice C rationale: Observing both lower extremities for redness and swelling is the most important assessment for evaluating the effectiveness of IPC devices. Redness and swelling can be signs of DVT, which IPC devices are designed to prevent. Therefore, this assessment directly measures whether the devices are functioning as intended. Choice D rationale: Evaluating the client’s ability to use an incentive spirometer is important for preventing postoperative pulmonary complications, but it does not assess the effectiveness of IPC devices.
