Final answer:
A 16-Fr 5cc Foley catheter requires exactly 5 cubic centimeters (cc) of sterile water to fill its balloon to the specified capacity.
Step-by-step explanation:
The specific amount of sterile water used to fill a Foley catheter depends on the balloon's capacity. In the case of a 16-Fr 5cc Foley catheter, the number indicated by '5cc' reflects the maximum volume of water that the balloon can safely hold. Therefore, to properly inflate the catheter's balloon, you would use exactly 5 cubic centimeters (cc) of sterile water.
