Poor insertion and use of a needle that is too large can result in which of the following?

• A. Cicatrix formation and pitting
• B. Infection
• C. Hair loss
• D. Temporary swelling

Answer: (A)

When a needle is inserted poorly or is too large, it causes more tissue disruption in the dermal layer. The body’s wound-healing response then lays down collagen to repair that damage, which can lead to cicatrix formation—scar tissue that remains after healing. If the injury damages deeper dermal structures around hair follicles, the healing tissue can create depressions in the skin known as pits. This combination of scar formation with surface depressions best explains why those particular outcomes occur after excessive trauma from needle size or technique.

Infection is more about sterility than needle size, swelling is typically a temporary immediate reaction, and hair loss would require direct follicle damage without necessarily resulting in the characteristic pit-like scarring described here.
