Which of the following is classified as a clean-contaminated wound (Class II)?

A clean-contaminated wound is defined as a surgical incision that has entered a hollow organ but is performed in a controlled environment with prophylactic measures in place. A suprapubic prostatectomy fits this classification because it involves accessing the urinary bladder, which is inherently considered contaminated but done under sterile conditions.

In contrast, procedures such as an incision and drainage of an abscessed foot represent a contaminated wound due to the presence of infection and bacteria from the abscess. A coronary artery bypass graft (CABG) is typically considered a clean wound since it is performed in a sterile operative field without entry into any hollow viscera. Lastly, a gunshot wound is classified as dirty or contaminated due to the open nature of the injury and the presence of foreign material and potential infection from the environment.

Therefore, considering these classifications within the context of surgical procedures and wound cleanliness, a suprapubic prostatectomy is correctly classified as a clean-contaminated wound.
