Final answer:
To ensure proper functioning of a Jackson-Pratt drain, the nurse should empty and compress the drain reservoir, keep the drain higher than the surgical incision, and avoid clamping the drain when the client is ambulating.
Step-by-step explanation:
When caring for a client with a Jackson-Pratt drain, the nurse should follow certain interventions to ensure proper functioning of the drain. One of these interventions is to empty and compress the drain reservoir as needed. This helps maintain proper suction and allows for efficient drainage. Another important intervention is to keep the drain higher than the surgical incision. This prevents the backflow of fluid into the surgical site and promotes proper drainage. Additionally, it is important not to clamp the drain when the client is ambulating, as the drain needs to remain open for proper drainage.
