Three people need help at once. How would you assign the next steps?

Fictional queue at 09:00: a patient in Room 3 says they are having difficulty catching their breath; the dentist is in the next room. A sealed, documented lab package needs the authorized courier handoff by 09:10; reception colleague Maya is trained for that handoff and is free now. A routine caller was promised a scheduling callback by 09:05; Maya can also make that call. Room 2 needs seven minutes of approved preparation before its 09:15 appointment; assistant Lee is free and trained for it. The dentist controls care and room-allocation decisions; the practice manager resolves staffing conflicts. You must obtain acknowledgment for delegated work.
