Example Question #241 : Nclex
What is the mortality rate for children infected with measles?
1 in 10,000
1 in 50
1 in 2,000
1 in 500
1 in 20
1 in 500
Measles, while generally only a moderately severe disease, is fatal in one out of every 500 children who contract the virus.
Example Question #241 : Nclex
Genital herpes is caused by what virus?
Human herpes virus 7
Herpes simplex virus type 2
Herpes simplex virus type 1 and 2
Herpes simplex virus type 1
Herpes simplex virus type 1 and 2
Genital herpes is most frequently associated with herpes simplex virus 2 (HSV2), while herpes simplex virus 1 (HSV1) has been associated more often with oral herpes (cold sores). However, new evidence suggests that both viruses can live in either location: HSV1 can spread to the genitals and cause genital herpes, while HSV2 can be spread to the oral mucosa to cause cold sores.
Example Question #12 : Identifying Viruses
Adult complications from cytomegalovirus (CMV) are most common in what population?
Athletes
The elderly
Immunocompromised individuals
Teens
Immunocompromised individuals
In adult populations, cytomegalovirus poses the greatest risk to immunocompromised individuals, such as people on immunosuppressive drugs or in HIV patients who have developed AIDS. In pregnant people, CMV generally does not pose a risk to the mother, but rather to the fetus. Athletes and teens that are not immunocompromised often will have mild or unnoticeable symptoms when infected with CMV.
Example Question #15 : Viruses And Other Microorganisms
What type of virus is molluscum contagiosum?
Herpesvirus
Retrovirus
Poxvirus
Adenovirus
Poxvirus
Molluscum contagiosum is a form of poxvirus. Poxviruses are a family of enveloped group 1 double-stranded DNA viruses that includes molluscum contagiosum virus, smallpox virus, vaccinia virus, and monkeypox.
Example Question #242 : Nclex
Which of the following class of viruses is responsible for all warts, including plantar warts, genital warts, flat warts, and common warts?
Epstein Barr virus
Cytomegalovirus
Human papillomavirus
Herpes simplex
Human papillomavirus
All forms of warts are caused by the virus HPV, or human papillomavirus. In addition, HPV is the cause of a variety of dysplasias, including cervical dysplasia, vulvar dysplasia, and oropharyngeal cancer. None of the other viruses listed are associated with warts of any kind.
Example Question #17 : Viruses And Other Microorganisms
Over 70% of cervical cancers are associated with which two strains of human papillomavirus (HPV)?
2 and 7
6 and 11
16 and 18
31 and 33
16 and 18
While HPV strains 31 and 33 have been associated with genital malignancies, more than 70% of cervical dysplasia is associated with HPV strains 16 and 18. Strains 6 and 11 are associated with genital warts, while 2 and 7 are associated with common warts.
Example Question #51 : Microbiology
90% of cases of condylomata acuminata (genital warts) are caused by what two strains of human papillomavirus (HPV)?
6 and 11
30 and 54
51 and 52
42 and 43
6 and 11
While all of the strains of HPV may cause condylomata acuminata, 90% of all cases of genital warts are caused by just two strains: 6 and 11.
Example Question #243 : Nclex
All of the following are forms of herpes virus except __________.
Herpes simplex
Rotavirus
Epstein-Barr virus
Varicella-zoster
Rotavirus
There are more than 130 types of herpes viruses. Of those, 8 are known to infect humans. Some of the more common examples are herpes simplex 1 and 2, varicella / zoster, Epstein-Barr virus, and cytomegalovirus. Less common viruses include human herpes virus 6, human herpes virus 7, and Kaposi's sarcoma-associated herpesvirus. Rotavirus is not a herpes virus; rather, it is a double-stranded RNA virus in the Reoviridae family.
Example Question #53 : Microbiology
Human papillomavirus (HPV) is associated with increased risk of which of the following cancers?
All of these are correct
Vulvar cancer
Anal cancer
Oropharyngeal cancer
All of these are correct
Human papillomavirus has been associated with several forms of cancer, including cancers of the cervix, vulva, anus, and oropharynx. It is also associated with penile and vaginal dysplasias.
Example Question #54 : Microbiology
Which of the following is the microbe most frequently associated with the common cold?
Influenza
Adenovirus
Human coronavirus
Rhinovirus
Rhinovirus
Rhinovirus, a type of picornavirus, is implicated in up to 50-80% of cases of the common cold. Other less common causes include human coronavirus (15% of cases), influenza (10%), and adenovirus (5%).
