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.

Correct Answer is C
Explanation
A. "Salmonella is a bacterial infection." Salmonella is a gram-negative bacterium that causes foodborne illness.
B. "Salmonella symptoms include headaches, abdominal pain, diarrhea, nausea, vomiting, and fever." These are common symptoms of Salmonella infection, particularly gastroenteritis.
C. "Salmonella may be spread by spores that form once contaminated blood is exposed to the air." Salmonella is a bacterial infection that spreads primarily through contaminated food, water, or direct contact with infected animals. It does not form spores, and exposure to air does not play a role in its transmission.
D. "Salmonella has a 48-hour incubation period." While the incubation period can range from 6 to 72 hours, 48 hours falls within the expected time frame.
Correct Answer is D
Explanation
A. Risk communication: Risk communication involves informing the public about health risks but does not specifically address social inequalities in environmental hazards.
B. Tertiary prevention: Tertiary prevention focuses on managing existing health conditions, not preventing environmental injustices.
C. Environmental epidemiology: Environmental epidemiology studies the relationship between environmental exposures and health outcomes but does not directly advocate against environmental injustice.
D. Environmental justice: Environmental justice focuses on ensuring that all communities, regardless of race or socioeconomic status, receive equal protection from environmental hazards. Opposing the construction of a waste site in a disadvantaged area aligns with this principle.
