Hand hygiene in wound care primarily prevents which of the following?

• A. Improved skin hydration
• B. Faster wound closure
• C. Growth of bacteria
• D. Infection

Answer: (D)

Hand hygiene during wound care mainly reduces the risk of infection. By cleaning the hands, you lower the number of bacteria that can be transferred to the wound or surrounding skin during dressing changes or wound cleaning. Fewer pathogens entering the wound means a lower chance of colonization progressing to an infection, which is the primary clinical concern in this context.

This doesn’t directly hydrate the skin or speed up healing, and while it reduces bacterial presence, the most important outcome in practice is preventing infection rather than just limiting bacterial growth in general.
