Questions: After emptying the drainage from a Jackson-Pratt drain, which action will the nurse prioritize to re-establish suction to the drain? Fully compress the bulb and reapply the cap. Reapply the cap and fully compress the bulb. Turn the suction back on at the wall unit. This type of drain does not use suction.

The answer is the first one: Fully compress the bulb and reapply the cap.

Explanation for each option:

1. Fully compress the bulb and reapply the cap: This is the correct procedure. The Jackson-Pratt drain works by creating a vacuum when the bulb is compressed. After emptying the drainage, the nurse should fully compress the bulb to re-establish the suction and then reapply the cap to maintain the vacuum.

2. Reapply the cap and fully compress the bulb: This is incorrect because reapplying the cap before compressing the bulb would not allow the vacuum to be created. The bulb must be compressed first to expel the air and create the necessary suction.

3. Turn the suction back on at the wall unit: This is incorrect because a Jackson-Pratt drain is a closed suction device that operates independently of wall suction units. It relies on the manual compression of the bulb to create suction.

4. This type of drain does not use suction: This is incorrect because the Jackson-Pratt drain specifically uses suction to help remove fluids from the surgical site. The suction is created by compressing the bulb.

Summary: To re-establish suction to a Jackson-Pratt drain after emptying it, the nurse should fully compress the bulb and then reapply the cap. This action creates the necessary vacuum to continue draining fluids effectively.
