Which of the following is a fatal consequence of leaving a wound untreated?

Severe infection is a critical consequence of leaving a wound untreated because when a wound is left open to the environment, it becomes a potential entry point for bacteria and other pathogens. The body’s immune system can often manage minor infections, but if a wound is significant and untreated, the infection can escalate rapidly. This could lead to systemic issues such as sepsis, which is a life-threatening response to infection that can impair organ function and lead to death.

In untreated wounds, the infection can cause extensive tissue damage, complicating the healing process and potentially resulting in the need for amputation or other drastic medical interventions. Recognizing the importance of treating wounds promptly is crucial in preventing infection and ensuring that an individual does not experience life-threatening complications.

The other choices do not represent fatal consequences. Reduced swelling is generally a desirable outcome, increased blood flow can be beneficial as it aids in healing, and enhanced healing time does not imply a negative outcome.
