Questions and Answers
  • 1. 

    If a microorganism is known to produce a disease, it is referred to as a

    • A. 

      Pathogen

    • B. 

      Pathogenic microorganism

    • C. 

      Normal flora

    • D. 

      A and B only

    • E. 

      All of the above

    Correct Answer
    D. A and B only
    Explanation
    A microorganism that is known to produce a disease is referred to as a pathogen. Pathogens are capable of causing infections or diseases in their hosts. Therefore, both options A (pathogen) and B (pathogenic microorganism) are correct as they describe the same concept. Option C (normal flora) is incorrect because normal flora refers to the microorganisms that naturally reside in or on the body without causing harm or disease. Option D (A and B only) is correct because it includes the correct options A and B, while option E (All of the above) is incorrect as it includes the incorrect option C.

    It is not necessary to wash your hands after removing gloves because your hands are protected by the gloves.

    • A. 

      True

    • B. 

      False

    Correct Answer
    B. False
    Explanation
    It is not necessary to wash your hands after removing gloves because your hands are not protected by the gloves. Gloves can become contaminated during use, and removing them without washing hands can transfer any pathogens or contaminants from the gloves to the hands. Therefore, it is important to wash hands thoroughly after removing gloves to maintain proper hygiene and prevent the spread of germs.

    An insect or animal carrier of a disease is known as:

    • A. 

      Fomite

    • B. 

      Vehicle

    • C. 

      Vector

    • D. 

      Carrier

    Correct Answer
    C. Vector
    Explanation
    A vector is an insect or animal that can transmit a disease-causing organism from one host to another. This can include mosquitoes, ticks, and flies, among others. These vectors are capable of carrying pathogens such as bacteria, viruses, or parasites, and can introduce them into a new host through biting or other means. By transmitting these pathogens, vectors play a significant role in the spread of many diseases, such as malaria, dengue fever, and Lyme disease.

    The most common means of spreading infection are:

    • A. 

      Soiled instruments

    • B. 

      Infected patients

    • C. 

      Human hands

    • D. 

      Domestic animals

    Correct Answer
    C. Human hands
    Explanation
    Human hands are the most common means of spreading infection because they come into contact with various surfaces and can easily transfer pathogens from one person to another. People often touch their faces, eyes, nose, and mouth without realizing it, providing a direct entry point for pathogens. Additionally, hand hygiene practices, such as washing hands with soap and water or using hand sanitizers, are not always followed properly, further increasing the risk of spreading infection through human hands.

  • 5. 

    Hepatitis A and B are transmitted by the fecal-oral route.

    • A. 

      True

    • B. 

      False

    Correct Answer
    A. True
    Explanation
    Hepatitis A and B are transmitted through the fecal-oral route, which means that the virus is passed from an infected person's feces to the mouth of another person. This can occur through contaminated food or water, poor hygiene practices, or close personal contact with an infected individual. The viruses can survive outside the body for extended periods and can be easily transmitted if proper sanitation measures are not followed. Therefore, it is important to practice good hygiene, such as washing hands thoroughly and avoiding consumption of contaminated food or water, to prevent the spread of these diseases.

    Which of the following are the factors that increase a patient's potential for acquiring a nosocomial infection?

    • A. 

      Age

    • B. 

      Nutritional status

    • C. 

      Close proximity to other patients

    • D. 

      Inadequate stress management

    • E. 

      All of the above

    Correct Answer
    E. All of the above
    Explanation
    All of the factors listed (age, nutritional status, Close Proximity to Other Patients, and inadequate stress) can increase a patient's potential for acquiring a nosocomial infection. Age can weaken the immune system, making individuals more susceptible to infections. Poor nutritional status can impair immune function, making it harder for the body to fight off infections. Close proximity to other patients can also weaken the immune system, making individuals more vulnerable to infections. Inadequate stress management can further weaken the immune system, increasing the risk of acquiring infections. Therefore, all of these factors can contribute to a patient's potential for acquiring a nosocomial infection.

    Hand hygiene is to be used in the following situations by imaging professionals in the workplace.

    • A. 

      Before caring for a patient

    • B. 

      After caring for a patient

    • C. 

      When preparing for an invasive procedure

    • D. 

      1 and 3 only

    • E. 

      1, 2, and 3

    Correct Answer
    E. 1, 2, and 3
    Explanation
    Hand hygiene is crucial in healthcare settings to prevent the spread of infections. Imaging professionals, like all healthcare workers, should practice hand hygiene in various situations. Before caring for a patient, hand hygiene is necessary to minimize the risk of transmitting microorganisms from the hands to the patient. After caring for a patient, hand hygiene is essential to remove any potential contaminants from the hands. Additionally, when preparing for an invasive procedure, hand hygiene is crucial to prevent the introduction of microorganisms into the patient's body. Therefore, the correct answer is 1, 2, and 3.

    Healthcare workers often contract Hepatitis B from needle-stick injuries.

    • A. 

      True

    • B. 

      False

    Correct Answer
    A. True
    Explanation
    Healthcare workers are at a higher risk of contracting Hepatitis B due to the nature of their work, which involves frequent exposure to blood and bodily fluids. Needle-stick injuries, which occur when a healthcare worker accidentally punctures their skin with a contaminated needle, are a common mode of transmission for Hepatitis B. This is why it is crucial for healthcare workers to follow strict safety protocols, such as using needle safety devices and practicing proper infection control measures, to minimize the risk of contracting Hepatitis B and other bloodborne diseases.

    Which of the following refers to a patient who enters a hospital with a known infection?

    • A. 

      Nosocomial infection

    • B. 

      Iatrogenic infection

    • C. 

      Community-acquired infection

    • D. 

      Idiopathic infection

    Correct Answer
    C. Community-acquired infection
    Explanation
    A patient who enters a hospital with a known infection is referred to as having a community-acquired infection. This term is used to describe infections that are acquired outside of a healthcare setting, such as in the community or at home, before the patient is admitted to the hospital. It is important to differentiate community-acquired infections from nosocomial infections, which are acquired within a hospital or healthcare facility, and iatrogenic infections, which are caused by medical treatment or procedures. The term "idiopathic infection" refers to an infection of unknown cause, which is not applicable in this context.

    Rate this question:

  • 10. 

    Which of the following are elements needed to transmit an infection?

    • A. 

      Infectious agent

    • B. 

      Reservoir

    • C. 

      Means of transmission

    • D. 

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    The correct answer is "All of the above." To transmit an infection, all three elements mentioned are needed. The infectious agent refers to the pathogen or microorganism that causes the infection, such as bacteria or viruses. The reservoir is the source or habitat where the infectious agent lives and multiplies, such as humans, animals, or the environment. Lastly, the means of transmission refers to the way the infectious agent is transferred from the reservoir to a susceptible host, which can include direct contact, airborne droplets, contaminated objects, or vectors like mosquitoes. Therefore, all three elements are necessary for the transmission of an infection.
