    HBV cannot be transmitted by sexual activity.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    HBV can be transmitted through sexual activity. This is because the hepatitis B virus (HBV) can be present in the blood, semen, and vaginal fluids of an infected person. Therefore, engaging in unprotected sexual activity with an infected individual can lead to the transmission of HBV. It is important to practice safe sex and use barrier methods such as condoms to reduce the risk of transmission.

    HBV has an incubation period of

    • A.

      2 weeks

    • B.

      4 weeks

    • C.

      7 weeks

    • D.

      12 weeks

    Correct Answer
    D. 12 weeks
    Explanation
    The correct answer is 12 weeks because HBV (Hepatitis B Virus) has an incubation period of approximately 12 weeks. During this period, a person may be infected with the virus but not show any symptoms. After the incubation period, symptoms such as fatigue, abdominal pain, and jaundice may start to appear. It is important to note that the incubation period can vary from person to person, but 12 weeks is the average duration.

      2 weeks

    • B.

      4 weeks

    • C.

      7 weeks

    • D.

      12 weeks

    Correct Answer
    C. 7 weeks
    Explanation
    The correct answer is 7 weeks because the incubation period of HCV, which stands for Hepatitis C Virus, is typically around 7 weeks. During this period, the virus replicates in the body and may not show any symptoms. After the incubation period, symptoms may start to appear, such as fatigue, jaundice, and abdominal pain. It is important to note that the incubation period can vary from person to person, ranging from 2 to 26 weeks.

    Rate this question:

  • 7. 

    HIV has an incubation period of

    • A.

      2 weeks

    • B.

      4 weeks

    • C.

      7 weeks

    • D.

      12 weeks

    Correct Answer
    D. 12 weeks
    Explanation
    The correct answer is 12 weeks because HIV has a variable incubation period, which refers to the time between initial infection and the appearance of detectable antibodies in the blood. On average, it takes about 12 weeks or 3 months for HIV antibodies to develop and become detectable through standard testing methods. However, it is important to note that this period can vary from person to person, and in some cases, it may take longer for antibodies to be detectable. Therefore, it is recommended to get retested if there is a possibility of HIV exposure within the last 3 months, even if the initial test result is negative.

    Symptoms for HCV are weight gain, backaches, and red rashes.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because weight gain, backaches, and red rashes are not symptoms of HCV (Hepatitis C Virus). Common symptoms of HCV include fatigue, fever, loss of appetite, nausea, and jaundice. Weight gain, backaches, and red rashes may be associated with other conditions or factors, but they are not directly related to HCV.

    Blood, lymph, cerebrospinal fluid, and semen are body fluids that can carry bloodborne pathogens.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Blood, lymph, cerebrospinal fluid, and semen are body fluids that can carry bloodborne pathogens. Blood is a well-known carrier of bloodborne pathogens such as HIV, hepatitis B, and hepatitis C. Lymph, which is a clear fluid that circulates throughout the lymphatic system, can also carry these pathogens. Cerebrospinal fluid, found in the brain and spinal cord, can transmit certain infections like meningitis. Semen, the fluid that contains sperm, can transmit sexually transmitted infections like HIV and gonorrhea. Therefore, it is true that these body fluids can carry bloodborne pathogens.

    Eye-washing stations are an example of an engineering control in the workplace.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Eye-washing stations are designed to provide immediate flushing of the eyes in case of exposure to hazardous substances. They are considered an engineering control because they are a physical device implemented in the workplace to mitigate the risk of eye injuries or chemical exposures. Engineering controls are measures that are built into the work environment to eliminate or minimize hazards, and eye-washing stations serve this purpose by providing a means to quickly and effectively rinse the eyes in case of an emergency.
