What action should a nurse take regarding a Penrose drain in a postoperative client?

Leaving the drain insertion site open to air is appropriate for managing a Penrose drain in a postoperative client because it allows for adequate drainage and ventilation of the wound area. Penrose drains are designed to promote passive drainage of fluids from a surgical site, and exposing the area to air can help prevent moisture buildup, which may lead to infection. Additionally, it helps to facilitate the drainage process by avoiding obstruction, ensuring that the fluid can flow freely out of the wound.

Keeping the site completely covered at all times may trap moisture, increasing the risk of infection or delayed healing. Clamping the drain periodically is generally not recommended as it can create pressure and may prevent proper drainage. The practice of changing the dressing every hour is excessive for a Penrose drain, as frequent dressing changes can disturb the healing process and expose the wound to infection. Proper care of a Penrose drain involves monitoring for signs of infection and ensuring the drain is functioning without obstruction while maintaining proper wound care.
