A nurse is reinforcing health teaching about skin cancer with a group of clients. Which of the following risk factors should the nurse identify as the leading cause of skin cancer?
Scars from a severe burn
Exposure to environmental pollutants
History of viral illness
Sun exposure
The Correct Answer is D
A. Scars from a severe burn: Although burn scars may increase skin sensitivity and vulnerability, they are not a primary cause of skin cancer.
B. Exposure to environmental pollutants: Some pollutants may contribute to skin damage, but UV radiation is the primary cause of skin cancer.
C. History of viral illness: Some viruses, such as HPV, are linked to specific cancers (e.g., cervical cancer), but they are not a primary cause of skin cancer.
D. Sun exposure: UV radiation from the sun is the most significant risk factor for skin cancer, particularly basal cell carcinoma, squamous cell carcinoma, and melanoma.

Correct Answer is D
Explanation
A. Formation of large amounts of ATP: Large ATP production occurs in aerobic respiration, not anaerobic metabolism. Lactic acidosis happens when there is a lack of oxygen and insufficient ATP production.
B. Muscle soreness: While lactic acid buildup may contribute to temporary muscle discomfort, muscle soreness alone does not indicate lactic acidosis, which is a systemic condition.
C. Formation of ketone bodies: Ketone bodies are produced during fat metabolism (e.g., in diabetic ketoacidosis), not anaerobic glucose metabolism.
D. Anaerobic breakdown of glucose: When oxygen levels are low, cells undergo anaerobic respiration, converting glucose to lactic acid instead of completely breaking it down through aerobic respiration. This leads to lactic acidosis.
Correct Answer is D
Explanation
A. Regeneration: Regeneration refers to the complete replacement of damaged tissue with the same type of cells, which is different from scar formation.
B. Sarcoma: Sarcoma is a type of malignant tumor originating in connective tissue, not a process of scar formation.
C. Meninges: The meninges are protective membranes surrounding the brain and spinal cord; they are unrelated to scar tissue formation.
D. Fibrosis: Fibrosis is the process of scar tissue formation when normal tissue is replaced by fibrous connective tissue after an injury.
