Final answer:
Cellulitis can spread to muscles, bones, and lymph nodes if left untreated, hence the correct answer is D) All of the above. The condition that results in the formation of a bubo is lymphadenitis, and vasculitis refers to inflammation of blood vessels.
Step-by-step explanation:
If left untreated, cellulitis can spread to muscles, bones, and lymph nodes, so the correct answer is D) All of the above. Cellulitis is a bacterial infection of the skin and tissues beneath the skin. Once the bacteria breach the skin barrier through a cut or wound, it can spread to nearby tissues and potentially enter the lymphatic and circulatory system. This can result in a wider dissemination of bacteria throughout the body, leading to more severe conditions such as abscesses, or even systemic infections if the bacteria reach the bloodstream.
Additionally, one of the conditions that result in the formation of a bubo is lymphadenitis (B). Buboes are swollen lymph nodes that can occur when the lymphatic system is infected.
In terms of other medical terms relevant to infections, vasculitis (D) refers to an inflammation of the blood vessels. It is important to understand these various infections and inflammatory conditions to properly diagnose and treat bacterial skin infections and prevent them from spreading.
