When the patient complains that he feels he is getting worse because of the increased swelling at his wound site on his leg, the nurse's most helpful response would be that swelling indicates that:

Choice A rationale:

Moistening the dressing with povidone iodine could cause irritation and is not the best method for removing a dressing stuck to the wound bed.

Choice B rationale:

Pulling off the dressing using slow, steady pressure could cause trauma to the wound bed and increase pain.

Choice C rationale:

Adding normal saline to loosen the dressing minimizes trauma to the wound bed and reduces pain during dressing removal.

Choice D rationale:

Leaving the old dressing in place and covering it with new, wet dressings could lead to infection and is not the best method for managing a dressing stuck to the wound bed.

Choice A rationale:

Refraining from touching the drainage spout with the hand is a correct practice. This helps to prevent contamination of the drain.

Choice B rationale:

Using one alcohol wipe to clean both the spout and the plug is incorrect. Each part should be cleaned with a separate alcohol wipe to prevent cross-contamination.

Choice C rationale:

Pointing the device away from oneself while opening it is a correct practice. This helps to prevent accidental exposure to the drainage fluid.

Choice D rationale:

Compressing the device in the hand before closing is a correct practice. This helps to maintain the suction in the drain.
