8) ANSWER B)Squeeze the collection chamber.

Explanation

The nurse should squeeze the collecting chamber to reestablish negative pressure and suction to the device. The nurse then wipes the port with alcohol before closing to reduce the risk of infection. The tubing should always be free of kinks to prevent obstruction. The core issue of the question is which action by the nurse will reestablish suction to a Jackson Pratt wound-drainage device. Use nursing knowledge and the process of elimination to make a selection.
