What should a nurse do regarding the post-mastoidectomy dressing?

Reinforcing the post-mastoidectomy dressing is the appropriate action for the nurse to take. After surgery, it is critical to ensure that the dressing remains secure and effectively absorbs any drainage without being disturbed. Reinforcement allows for additional support while preserving the integrity of the original dressing, which is important to protect the surgical site and promote healing.

Checking the dressing hourly is not typically necessary unless there are signs of excessive drainage or other concerns that require close monitoring. Leaving the dressing unchanged may lead to complications if there is significant bleeding or drainage, as those factors would require intervention. Changing the dressing immediately would not be advisable, as it could disrupt any clotted areas that are important for healing and may increase the risk of infection. Reinforcing the dressing strikes a balance between maintaining the surgical site protection and providing the opportunity to monitor for any complications.
