Which statement by the patient indicates an understanding of the education provided post-wound closure?

The statement indicating an understanding of the education provided post-wound closure is that red streaks or drainage may mean an infection. This reflects knowledge about signs of infection, which is crucial after any wound closure. Recognizing red streaks or abnormal drainage indicates that the patient is aware that these are warning symptoms requiring prompt medical attention. This understanding is essential for preventing complications and ensuring proper healing of the wound.

The other statements demonstrate misunderstandings about wound care. For example, while some pain may be expected as a part of the healing process, severe pain could be indicative of complications, thus making the expectation of severe pain inappropriate. Furthermore, the assertion that vitamin E aids in wound healing is misleading, as current evidence does not support its use for this purpose. Lastly, the idea of being able to shower right away does not align with general post-operative advice, as it is usually recommended to keep the area dry and covered until it has adequately healed to prevent infection.
