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.

A. Herd immunity: Herd immunity occurs when a large portion of the population is immune, reducing the spread of disease. However, the individual receiving the vaccine develops active immunity, not herd immunity.
B. Natural immunity: Natural immunity occurs after infection and recovery, not from vaccination.
C. Acquired immunity: While acquired immunity includes both active (vaccination or infection) and passive (antibodies from mother or immunoglobulin) immunity, the most specific answer is active immunity.
D. Active immunity: Vaccines stimulate the immune system to develop long-term immunity by producing antibodies against the virus.
Correct Answer is B
Explanation
A. Putting students on a diet if they weigh greater than 20% of their ideal weight: This is a tertiary prevention strategy, as it focuses on managing obesity after it has been diagnosed rather than early detection.
B. Weighing students to identify those who are overweight: Secondary prevention focuses on early detection and intervention to prevent disease progression. Weighing students allows for early identification of obesity and timely interventions.
C. Giving a presentation on the importance of exercise and physical fitness: This is primary prevention, which aims to prevent obesity before it occurs by promoting healthy habits.
