• suspected nonaccidental trauma
• skeletal dysplasias, syndromes, and metabolic disorders
• neoplasms

Answer:

• 1, 2, 3

The American College of Radiology provides 3 indications for skeletal surveys: suspected nonaccidental trauma; skeletal dysplasias, syndromes, and metabolic disorders; and neoplasms.Question 2: PA chest taken using 300 mA, 0.008 seconds, 110 kVp. If exam repeated using AEC w/min response time of 10 ms, which factors appropriate?

• 400 mA, 0.006 seconds, 110 kVp
• 200 mA, 0.012 seconds, 110 kVp
• 600 mA, 0.004 seconds, 110 kVp

• All

Answer:

• 200 mA, 0.012 seconds, 110 kVp

Min resp time (MRT)=how long AEC to detect/respond to exp. Here, MRT is 10 ms (0.01 seconds). AEC won't term exp <0.01 secs. If exp time is less than MRT, RE increases b/c unit won't turn off until MRT reached.Question 3: Which guideline is used to reduce personnel/patient dose during fixed fluoroscopy?

• 30 Roentgens (R)/min maximum tabletop exposure rate
• 15-inch minimum SSD
• minimum filtration of 1.5 mm aluminum equivalent
• 0.5 mm primary protective barrier

Answer:

• 15-inch minimum SSD

The minimum source-to-skin distance for a fixed fluoroscopy unit is 15 inches.Question 4: 3 projections taken for long-bone measurement (scanography technique) of lower

extremity include:

• AP hip, lateral femur, AP lower leg
• AP hip, lateral knee, AP lower leg
• AP femur, AP lower leg, AP foot
• AP hip, AP knee, AP ankle

Answer:

• AP hip, AP knee, AP ankle

Scanography technique involves using 3 separate IRs to acquire AP projections of hips, knees, and ankles. Very important that patient does not move between exposures to ensure all projections are same.

Question 5: The BEST reason to use touch for emphasis when performing a radiologic

examination is to:

• specify instructions or locations
• convey empathy
• measure body part before choosing exposure factors
• ID landmarks

Answer:

• specify locations or instructions

Touch from tech can assist a patient w/understanding appropriate positioning or communicate locations for specific examination. Empathy can reassure patients, but is expressed more in words and tone than in touch.Question 6: According to NCRP Report No. 116, annual occupational exposure to the lens of the

eye should not exceed:

• 25 mSv
• 50 mSv
• 100 mSv
• 150 mSv

Answer:

• 150 mSv

NCRP Report No. 116 states that the annual occupational exposure limit for the lens of the eye is 150 mSv, or 15 rem.Question 7: Which are the appropriate methods to ensure the correct drug is administered to the patient?

• Confirm the correct medication.
• Record the time and date of administration.
• Check the label at least 3 times.

Answer:

• 1 and 3

Tech verifies med/check label 3x.

• When draw med (similarity many med names)

• Admin med

• Replace container

Recording date/time doesn't determine right drug, but is required.Question 8: Which type of communication includes eye contact, touch and tone of voice?

• verbal
• nonverbal
• paralanguage
• body languqage

Answer:

• nonverbal

Nonverbal communication includes all exchange of information from one person to another absent actual words of speech. Paralanguage/body language considered forms of nonverbal communication.Verbal communication includes speech and grammar Question 9: If 90 kVp is used with a single-phase generator, the minimum electron voltage across the tube is ________ keV.

• 90
• 60
• 30
• 0

Answer:

• 0

Single-phase generators have a 100% ripple factor. This means that the voltage across the tube drops to "0" during an x-ray exposure.
