Final answer:
The nurse should expect the HCP to order an antiplatelet medication for a client with arterial occlusive disease, as these medications help prevent blood clots and improve blood flow in the arteries.
Step-by-step explanation:
For a client diagnosed with arterial occlusive disease, the most appropriate medication that a nurse should expect a healthcare provider (HCP) to order is c. An antiplatelet medication. Antiplatelet drugs, such as aspirin, are often used preventively when plaque buildup is evident to prevent further blood clot formation and improve blood flow in the arteries. Given that arterial occlusive disease involves the obstruction of blood flow due to plaque build-up and potential blood clots, antiplatelet medications help by inhibiting platelet aggregation and are beneficial in managing this condition.
