Go-around

Cockpit communication
First Officer: Problem in the cabin. Flight attendant just collapsed. Tom is doing initial assessment: checking airway, respiration, and circulation.
Captain: Understood. Ask him how long until the cabin is secured for landing.
First Officer: Twenty minutes to address medical emergency and secure the cabin. Meal trays are still out but not yet collected.
Captain: Twenty minutes? We're only fifteen from touchdown. 
First Officer: Maybe declare a medical emergency with ATC. We won't have time to land safely with the cabin unsecured.
Captain: We'll initiate a go-around. This should give the crew the extra time needed to stabilize the situation and secure the cabin properly. Wheels up.

So we did go round again. The passengers had to wolf down their curries before trays were hastily collected. And on landing the flight attendant was taken off first.
