Which client profile presents the greatest risk for human immunodeficiency virus (HIV) infection?

The client profile that presents the greatest risk for human immunodeficiency virus (HIV) infection is the adolescent with multiple heterosexual contacts. This scenario highlights several factors that contribute to increased vulnerability to HIV infection.

Firstly, individuals in adolescent age groups are often less informed about safe sex practices and may engage in riskier behaviors compared to older populations. Multiple heterosexual contacts suggest a higher likelihood of exposure to sexually transmitted infections (STIs), including HIV, particularly if consistent and correct condom use is not practiced.

Additionally, young people are statistically more likely to have partners of varying sexual health statuses, which can further elevate their risk. This demographic often experiences changes in sexual behavior, exploratory practices, and peer influences, which can lead to increased exposure.

In contrast, profiles like a married woman with one partner, a middle-aged man with stable relationships, or a single woman with a long-term boyfriend generally indicate either fewer sexual partners or stable and possibly safer sexual practices, reducing their risk of HIV exposure. Stable relationships typically correlate with a mutual understanding of sexual health and testing between partners, thus lowering the likelihood of infection.
