A teenager who is scheduled to undergo surgery will likely be primarily concerned with which of the following?

In the context of a teenager preparing for surgery, body image tends to be a significant concern. Adolescence is a developmental stage marked by increased self-awareness and sensitivity to how one is perceived by others. Teenagers are often highly focused on their appearance, and undergoing surgery can impact their body image. They may worry about how surgery and any resultant changes will affect their physical attractiveness and social interactions.

While factors like recovery time and scar appearance are also relevant, they might not hold the same emotional weight for teenagers as their body image. Concerns about current skin condition can be important as well, but they are usually secondary to the overarching issue of how surgery will affect a teenager's overall perception of themselves. Therefore, body image emerges as the central concern in this scenario.
