Which of the following is a common complication to monitor for a client with a JP drain?

In patients with a Jackson-Pratt (JP) drain, monitoring for infection is crucial due to the nature of how drains are placed and function. A JP drain is designed to remove fluid that accumulates around a surgical site, and it creates an entry point into the body that can potentially allow bacteria to enter. Signs of infection may include localized redness, swelling, increased drainage, fever, and warmth around the insertion site. Vigilant monitoring for these signs allows for early intervention, which is vital given that an infection can lead to systemic complications and delayed healing.

While fluid accumulation and increased pain may also be concerns, they are generally expected challenges that may arise post-surgery, especially with a drain in place. Allergic reactions to the materials of the drain are less common, as the materials used are typically biocompatible and safe for use in most patients. Thus, while those options represent potential concerns, the most pertinent and common complication requiring close monitoring with a JP drain is infection.
