Step-by-step explanation:
The priority nursing diagnosis that would be appropriate for Mr. Thomas is Risk for infection.
Mr. Thomas's refusal of dressing changes puts him at risk for infection because keeping the incisions closed without proper care increases the chances of bacteria entering the wounds and causing an infection. Dressing changes are important to maintain hygiene, prevent contamination, and promote healing. By refusing the dressing changes, Mr. Thomas is compromising his own health and well-being.
The nurse should prioritize addressing the risk for infection by explaining to Mr. Thomas the importance of regular dressing changes and providing education on proper wound care and hygiene practices.
