What is priapism?

Priapism is defined as a painful, persistent erection that lasts for four hours or more and occurs without sexual arousal or excitement. This medical condition is significant because it can lead to serious complications such as erectile dysfunction or tissue damage if not treated promptly. The prolonged erection is often a result of an obstruction in blood vessels or other underlying medical issues.

Understanding priapism is crucial in emergency nursing, as quick recognition and treatment are required to prevent long-term consequences. The other choices refer to different sexual or medical conditions that do not accurately describe priapism's characteristics or implications.
