Question 9

Match the correct term about radiation to the correct definition. You may use the same answer more than once.
-Lead aprons must be stored flat or hung in a manner that prevents bending of the material.

Accepted Answer

Lead aprons are used as a protective measure against ionizing radiation, which can cause damage to living tissue. Hanging them properly prevents damage to the apron, ensuring its effectiveness in blocking this type of radiation.

Question 10

Match the correct term about radiation to the correct definition. You may use the same answer more than once.
-Lead aprons must be worn during fluoroscopy to prevent exposure to scatter radiation.

Accepted Answer

Lead aprons are used to protect against ionizing radiation, which is the type of radiation produced during fluoroscopy. Ionizing radiation has enough energy to remove tightly bound electrons from atoms, thus creating ions, and can cause damage to the human body. Magnetic resonance imaging (MRI), on the other hand, uses magnetic fields and radio waves to generate images of the organs in the body and does not involve ionizing radiation.

Question 11

Choose from the terms listed and match them with their most correct descriptions. You may use the same answer more than once.
-Reduces the risk of transmission of airborne agents by droplet nuclei of 5 µm or less

Accepted Answer

Airborne transmission precautions are specifically designed to prevent the spread of pathogens that are transmitted through the air and can be suspended in the air over long distances and time, especially those with a size of 5 µm or less.

Question 12

Choose from the terms listed and match them with their most correct descriptions. You may use the same answer more than once.
-Precautions used when a patient is known to have impetigo or infection with any multidrug resistant bacterium

Accepted Answer

Impetigo and infections with multidrug-resistant bacteria require contact precautions to prevent the spread of infection through direct or indirect contact with the patient or the patient's environment.

Question 13

Choose from the terms listed and match them with their most correct descriptions. You may use the same answer more than once.
-Standards and precautions to prevent the spread of infectious disease by patients known to be infected

Accepted Answer

Transmission-based precautions are additional infection control measures used when caring for patients known to be infected with highly transmissible or epidemiologically important pathogens. These precautions are used in addition to standard precautions and are tailored based on the mode of transmission of the infectious agent (e.g., airborne, droplet, contact).

Question 14

Match the correct term about radiation to the correct definition. You may use the same answer more than once.
-Those who must remain in the room during exposure must maintain a distance of at least 6 feet (1.8 m) from the patient.

Accepted Answer

This statement refers to the precautions taken to minimize exposure to ionizing radiation, which is known for its ability to remove tightly bound electrons from atoms, thus creating ions. Magnetic resonance imaging (MRI), on the other hand, uses magnetic fields and radio waves, not ionizing radiation, and does not require such distance precautions.

Question 15

The recommended procedure to help prevent the development of blood-borne diseases after an exposure incident is ____________.

Accepted Answer

Post-exposure prophylaxis (PEP) is the recommended procedure to help prevent the development of blood-borne diseases after an exposure incident, such as a needlestick injury or a splash of potentially infectious material. PEP involves taking antiviral medication as soon as possible after the exposure to prevent the infection from taking hold.

Question 16

Choose from the terms listed and match them with their most correct descriptions. You may use the same answer more than once.
-Formerly called universal precautions

Accepted Answer

Standard precautions were formerly known as universal precautions. They are the basic level of infection control that should be used in the care of all patients regardless of their infection status.
