Final answer:
When a post ORIF distal pulse is weak and the extremity is cool, the priority is to immediately notify the healthcare provider to address potential serious complications.
Step-by-step explanation:
If post ORIF (Open Reduction and Internal Fixation) distal pulse is weak and the affected extremity is cool, the priority action is d) Notify the healthcare provider immediately. This could be indicative of a complication, such as compartment syndrome or inadequate blood flow to the extremity, which are medical emergencies. Elevating the extremity, applying warm compresses, or administering pain medication could be secondary measures, but they do not address the underlying concern. The healthcare provider should assess the situation to determine the appropriate intervention.
