When your at the nurse northwest of the fountain (you have to be visable to trigger her). She will ask, are you ill. Sayto nurse "no".
She will ask you if you want to help the miners. Sayto nurse "yes" and she will give you 5 pills.
You have to search in the mines for nervous miners and give them a pil. for each pill you get a work pass. Once you collect 5 work passes go back to nurse and turn in the passes.
She will reward you with PP or QP.
Update: I tried this August 2013 but only got 4 work passes - I got a reward for the first one only. You give a worker's pass to a frantic nurse. 'Thank you!' a frantic nurse exclaims. 'Well done!' You gain 14 quest points! a frantic nurse gives you 648 gold coins.
