What should the nurse do to reestablish the vacuum of the Hemovac system after emptying?

A) Place a safety pin on the part of the drain outside the body.
B) Replace the cap immediately after emptying.
C) Pin the drainage tubing to the patient's gown.
D) Place the Hemovac on a flat surface.

Place the evacuator on a flat surface with the open outlet facing upward;continue pressing downward until the bottom and the top are in contact;hold the surfaces together with one hand,quickly cleanse the opening and the plug with the other hand,and immediately replace the plug;and then secure the evacuator to the patient's bed.Compression of the surface of the Hemovac creates a vacuum.Cleansing of the plug reduces transmission of microorganisms into the drainage evacuation.Be sure the Penrose drain has a sterile safety pin in place.This pin prevents the drain from being pulled below the skin's surface.Compress the bulb of a JP drain over the drainage container.Cleanse the ends of the emptying port with an alcohol sponge while continuing to compress the container.Replacing the cap immediately prevents tension on the drainage tubing,but does not help to reestablish the vacuum.
