Final answer:
The most appropriate nursing diagnosis for a 16-year-old with severe acne is 'Body Image, Disturbed related to facial lesions,' due to the significant impact on self-perception and the common occurrence of acne in adolescence.
Step-by-step explanation:
A priority nursing diagnosis for a 16-year-old client with severe acne might best be c. Body Image, Disturbed related to facial lesions. Acne is a common skin disorder that can cause significant psychological and emotional distress, particularly during adolescence when issues of self-image and peer acceptance are heightened. This condition is exacerbated by hormonal changes that teenagers undergo, leading to an overproduction of sebum which, when combined with bacteria like Propionibacterium and Staphylococcus, can cause inflammation and the appearance of various skin lesions including pimples, whiteheads, blackheads, nodules, and potentially scarring. This can significantly affect a person's perception of their physical appearance, hence, the nursing diagnosis of 'Disturbed Body Image'. Severe acne can significantly impact an individual's body image and self-esteem, especially during adolescence. Addressing the emotional and psychological impact of the condition is crucial for the overall well-being of the client. While other aspects, such as anger, medication regimen, and health maintenance, are important, the immediate concern in this case is likely the disturbance in body image due to facial lesions.
