The nurse understands that which of the following is the most common vector-borne disease is a result of travelers introducing the disease to the United States?
Dengue
Malaria
Onchocerciasis (river blindness)
Yellow fever
The Correct Answer is B
A. Dengue: Dengue is transmitted by Aedes mosquitoes and is found in tropical regions, but it is less commonly imported to the U.S. than malaria.
B. Malaria: Malaria is the most frequently imported vector-borne disease in the U.S. due to international travelers coming from endemic areas (Africa, South Asia, South America). It is transmitted by Anopheles mosquitoes.
C. Onchocerciasis (river blindness): This disease is primarily found in Africa and is not commonly imported to the U.S. by travelers.
D. Yellow fever: While yellow fever exists in endemic areas, travelers are often vaccinated before visiting these regions, reducing its importation risk.

Correct Answer is A
Explanation
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 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.
