The Nurse Changing a Wet to Dry Normal Saline Dressing

The nurse changing a wet to dry normal saline dressing for a patient with an ulcer on the heel finds that the old dressing is stuck to the wound bed. The nurse's most beneficial intervention would be to:

A) add normal saline to loosen it.
B) pull it off using slow, steady pressure.
C) leave it in place and cover it with new, wet dressings.
D) moisten it with povidone iodine.
