Answer 1

gently tell the patient what you need to accomplish and how you would like to move forward with the examination.

Answer 2

a. giving clear, concise instructions to the patient before the exposure.

b. assessing the amount of patient cooperation you can expect and making adjustments in immobilization.

c. explaining how important it is to hold still during the exposure so that a good image can be obtained.

Question 3

The ideal patient immobilization device would be

Answer 3

radiolucent, durable, and easy to use for the radiographer.

Question 4

The technique of wrapping an infant patient in a sheet

Answer 4

is known as mummification.

Question 5

When obtaining cervical spine images on a patient with a cervical collar, complete

Answer 5

the AP and lateral projections with the cervical collar in place.

Question 6

When using a sheet to “mummify” an infant, the sheet should first be formed into a

Answer 6

triangle.

Question 7

When using sandbags as an immobilization device,

Answer 7

make a note for the radiologist, as the sandbag is radiopaque and may leave an artifact.

Question 8

The term bradypnea is used to describe

Answer 8

a decrease in respiratory rate.

Question 9

Thoracostomy tubes are used to

Answer 9

reestablish negative intrapleural pressure.

Question 10

When taking a portable chest radiograph on a patient undergoing oxygen therapy,

Answer 10

the oxygen should not be removed without the consent of a physician or respiratory care practitioner.

Question 11

While performing a portable chest radiograph on an uncooperative patient with a CV line inserted, you note that the catheter fixation material has loosened. Your responsibility as a professional radiographer is to

Answer 11

inform the patient’s nurse of the catheter issue before taking the radiograph.

Question 12

All of the following apply to respiratory measurements except

Answer 12

the respiratory rate of newborns averages 12 to 20 breaths/min.

Question 13

The ideal location of the endotracheal tube tip is

Answer 13

in the trachea 1 to 2 inches above the carina.

Question 14

A cardiac arrhythmia that is life threatening and provides no effective cardiac output is

Answer 14

V-fib.

Question 15

A possible complication of patients with a history of atrial fibrillation is

Answer 15

atrial emboli formation.

Question 16

A widened QRS complex on an ECG tracing could represent

Answer 16

a. ventricular hypertrophy.

b. ventricular-paced rhythm.

c. pacemaker tissue that is below the AV node.

Question 17

An effective method for treating select cardiac arrhythmias is the use of high-frequency alternating current to destroy strategic cardiac tissue and reroute the cardiac impulses generated. These procedures are known as

Answer 17

cardiac ablation treatments.

Question 18

Heart rates above 100 beats/min in an adult is termed

Answer 18

tachycardia.

Question 19

The cardiac arrhythmia of bradycardia generally involves abnormalities to the

Answer 19

SA and AV nodes.

Question 20

The QRS complex on a typical ECG represents

Answer 20

depolarization of ventricular muscle.

Question 21

A disease spread by kissing is being transmitted by which of the following methods?

Answer 21

Direct contact

Question 22

A nosocomial infection is an

Answer 22

infection acquired in a hospital.

Question 23

A pathogen that requires contact precautions is

Answer 23

MRSA.

Question 24

A person who acts as a reservoir of pathogenic organisms is referred to as a carrier. An example of a carrier is a

Answer 24

coworker who has demonstrated a cold for 2 weeks.

Question 25

All of the following are effective methods of sterilization except

Answer 25

isolation.

Question 26

In a hospital setting, constant awareness is given to the simple fact that patients come to the hospital because they are sick and vulnerable to disease. With the current system of medical care, by the time patients come to the hospital setting for care, they are sicker than ever in the past. The most common nosocomial infection seen in hospital patients is

Answer 26

urinary tract infections from Foley catheter insertions.

Question 27

The chain of infection consists of

Answer 27

host, infectious microbe, mode of transmission, and reservoir.

Question 28

Hazardous drug-related waste materials

Answer 28

require the labeling of needle containers and breakable items of hazardous waste.

Question 29

The goal of aseptic technique is to

Answer 29

protect the patient from pathogenic microbes.

Question 30

The role of the imaging technologist during cardiac pacemaker studies is to

Answer 30

operate fluoroscopy for the physician as he or she guides the pacemaker into position.

Question 31

Two people in sterile attire should pass each other in which of the following ways?

Answer 31

Back to back

Question 32

When using a portable fluoroscopy C-arm in surgery,

Answer 32

the image receptor and C-arm are draped with a snap cover for sterility.

Question 33

You are about to assist with a sterile procedure. In scrubbing for the procedure, it is important to

Answer 33

scrub the fingers completely, as well as the front and back of your hands, for 3 minutes.
