Respiratory measurements:

a single respiration cycle consists of an inspiration and expiration, the adult respiration quality refers to rhythm, depth, and degree of effort, and respiratory rates in children should be measured for one minute and may alter if the patient in supine

A temporal artery temperature of ______ degrees is normal

100

Peak blood pressure is:

systolic pressure

Body temperature:
oral temp higher than _______ indicates fever

99.5

Body temperature: Temporal artery (TA) is

measured in 3 seconds noninvasively

Body temperature: Rectal measurements...

are typically 1 degree higher than oral readings

Related temperature measurement routes:

oral, tympanic, and rectal

Body homeostasis...

- can be assessed quickly - the data is objective

Adequate breathing:

has a good respiratory rate, good respiratory depth, and 10-12 breaths/min

Vital signs:

- temperature - blood pressure - respiration - pulse

The radiation a person receives from the sun (cosmic radiation) is categorized as: A. natural background radiation. B. medical background radiation. C. atmospheric radiation. D. radioactivity.

A. Natural background radiation.

With regard to the ALARA principle, the responsibility of the radiographer is to: A. obtain high-quality radiographs in an efficient manner. B. keep radiation exposures at the lowest levels possible. C. assess image quality as a function of dose. D. determine the risk-to-benefit relationship between ordered examinations and dose.

Determine the risk-to-benefit relationship between ordered examinations and dose.

The dose equivalent limits for radiation workers are based on the radiation received from what source(s)? A. Background radiation B. Medical and dental radiography C. Occupational exposure D. Radiation fallout

C. occupational exposure

A woman who is 3 months pregnant has been in a motor vehicle accident. The emergency department physician suspects there is an injury to her cervical spine and thus feels justified in ordering an X-ray examination to aid in determining the extent of the patient’s injury. Because the patient is pregnant, the radiographer should: 1. Select the lowest exposure factors that will produce a diagnostically useful radiograph. 2. Adequately and precisely collimates the radiographic beam to include only the anatomic area of interest. 3. Shield the patient’s lower abdomen and pelvic region with a suitable protective contact shield. 4. Only perform the lateral projection to minimize radiation dose. A. 1 and 4 only B. 2 only C. 3 and 4 only D. 1, 2, and 3 only

D. 1, 2, and 3 only

Which of the following is a principle of the ALARA concept? A. All diagnostic X-ray exposure is low energy and of little concern. B. The radiographer should hold a standard number of patients per year as long as it is below the allowable limits. C. X-ray doses can increase progressively to allowable limits on older patients. D. The radiographer’s occupational exposure should be kept as low as reasonably achievable and the concept of “permissible dose” is no longer recognized.

D. The radiographer’s occupational exposure should be kept as low as reasonably achievable and the concept of “permissible dose” is no longer recognized.

Protective devices such as lead aprons are intended to protect the user from _____ radiation. 1. Compton scatter and secondary 2. primary 3. remnant 4. bremsstrahlung A. 1 only B. 1, 2, and 4 only C. 1 and 3 only D. 1, 3, and 4 only

B. Temperature, pulse, respiration, and blood pressure.

All of the following are true of body temperature measurement except: A. all temperatures should be the same, regardless of where the temperature is measured.

D. rectal and TA measurement are typically 1° higher than oral readings.

A. all temperatures should be the same, regardless of where the temperature is measured.

The peak blood pressure reading, when measuring blood pressures, is: A. diastolic pressure. B. systolic pressure C. blood pressure resulting from right ventricular contraction. D. insignificant, as it does not truly indicate resting blood pressure

All of the following apply to respiratory measurements except: A. a single respiration cycle consists of an inspiration and an expiration. B. the respiratory rate of newborns averages 12 to 20 breaths/min. C. adult respiration quality refers to rhythm, depth, and D. respiratory rates in children should be measured for at least one minute respiration measurements may alter if the patient is supine.

The term bradypnea is used to describe: A. a decrease in respiratory rate. B. the depth of respiration. C. difficulty in breathing. D. absence of breathing.

B. the depth of respiration.

All of the following are true of oxygen therapy except: A. the universal color of flowmeters is green. B. oxygen is considered a drug and is regulated by the government.
