For a client expressing that he finds the opening in his throat disgusting after laryngectomy, which nursing diagnosis is most appropriate?

The most appropriate nursing diagnosis in this scenario is related to disturbed body image resulting from the laryngectomy. Following such a surgical procedure, clients may experience significant changes in their appearance and the way they perceive their bodies. These changes can lead to feelings of disgust or distress, as expressed by the client regarding the opening in his throat.

A laryngectomy not only alters the physical attributes of the throat but also impacts how individuals perceive themselves and how they believe others perceive them. This profound alteration can deeply affect self-esteem and body image, making it essential for healthcare providers to address these feelings.

While other diagnoses could also be relevant in different contexts, the client's current expression of disgust and discomfort directly points to a struggle with how they view their body post-surgery, confirming that disturbed body image is the most fitting choice in this case.
