How can preserving skin integrity impact the circular chain of infection?
- A. Host
- B. Reservoir
- C. Mode of transmission
- D. Portal of entry
Correct Answer: D
Rationale: Preserving skin integrity plays a key role in breaking the chain of infection by eliminating the portal of entry for pathogens.

By maintaining skin integrity through proper hygiene and wound care, the risk of infection is significantly reduced, disrupting the cycle of infection transmission.
