Correct Answer is A
Explanation
A. HSV-2 is a viral infection that is both chronic and incurable: Unlike gonorrhea (a bacterial infection that can be treated with antibiotics), HSV-2 (Herpes Simplex Virus 2) is a lifelong viral infection with no cure. Antiviral medications can help manage outbreaks but do not eliminate the virus.
B. HSV-2 is extremely expensive to treat: While HSV-2 requires ongoing management, it is not necessarily more expensive than treating antibiotic-resistant gonorrhea, which can require costly treatments.
C. HSV-2, like HIV, can become life-threatening: HSV-2 itself is not typically life-threatening, though it can cause complications in immunocompromised individuals. Unlike HIV, it does not severely weaken the immune system.
D. Once a person has been treated for HSV-2, the person is immune to further outbreaks: This is false because HSV-2 remains dormant in the body and can reactivate, causing recurrent outbreaks.
Correct Answer is A
Explanation
A. Elevated growths with a "cauliflower" appearance: HPV lesions, or genital warts, present as raised, rough-textured growths resembling a cauliflower, often found in the genital and anal areas.
B. Thin-walled pustules that rupture to form honey-colored crusts: This describes impetigo, a bacterial skin infection, not HPV.
C. Vesicles that ulcerate and crust within 1 to 4 days: This describes herpes simplex virus (HSV) lesions, which differ from HPV warts in appearance and progression.
D. Solitary growth with elevated borders and a central depression: This describes basal cell carcinoma, not HPV-related lesions.
