Which of the following best describes the characteristic appearance of lesions of human papillomavirus (HPV)?
Elevated growths with a "cauliflower" appearance
Solitary growth with elevated borders and a central depression
Thin-walled pustules that rupture to form honey-colored crusts
Vesicles that ulcerate and crust within 1 to 4 days
The Correct Answer is A
A. Elevated growths with a "cauliflower" appearance: HPV lesions, commonly known as genital warts, have a characteristic raised, rough, and cauliflower-like appearance. These lesions are caused by HPV types 6 and 11.
B. Solitary growth with elevated borders and a central depression: This describes a basal cell carcinoma, which is a type of skin cancer, not HPV-related warts.
C. Thin-walled pustules that rupture to form honey-colored crusts: This describes impetigo, a bacterial skin infection typically caused by Staphylococcus aureus or Streptococcus pyogenes.
D. Vesicles that ulcerate and crust within 1 to 4 days: This describes herpes simplex virus (HSV) lesions, not HPV. HSV lesions appear as painful fluid-filled blisters that rupture and form ulcers.

Explanation
A. Clients with HIV infection are encouraged to use condoms to protect sexual partners. This is an example of primary prevention, which aims to prevent disease transmission before it occurs.
B. Health care workers are required to have a tuberculosis skin test or chest X-ray. Secondary prevention involves early detection and screening to identify disease in its early stages before symptoms develop or to prevent progression. TB screening (skin tests or chest X-rays) allows for early identification and treatment, preventing further transmission and severe disease.
C. Health care workers are encouraged to receive annual vaccinations for influenza. This is also primary prevention because vaccinations help prevent initial infection.
