Q: Foley catheter balloon should be inflated with (select one)
A) Sterile water
B) Normal Saline
Answer: Sterile water
Foley catheter balloon should be inflated with sterile water (after urine flow is confirmed). Normal Saline should never be used to inflate the Foley catheter balloon because it may cause crystal formation, obstruct the balloon channel and later prevent the deflation of balloon.
