ASRT EXAM 8 QUESTIONS AND ANSWERS
The inferior and posterior portion of the calcaneus to which the Achilles tendon attaches
is named the:
1. calcaneal tuberosity
2. sustentaculum tali
3. trochlea
4. calcaneal sulcus - Answers - calcaneal tuberosity
(The Achilles tendon attaches to the calcaneal tuberosity. The tuberosity is a knob-
shaped, roughened surface that the Achilles, or calcaneal, tendon attaches to.)
The minimum lead equivalent for lead aprons used during fluoroscopy is:
1. 0.25 mm.
2. 0.50 mm.
3. 0.75 mm.
4. 1 mm. - Answers - 0.50
(The minimum lead equivalent for lead aprons used in fluoroscopy is 0.50 mm.)
What structures create the carpal tunnel?
1. carpal bridge and flexor retinaculum
2. carpal bridge and extensor retinaculum
3. carpal sulcus and flexor retinaculum
4. carpal sulcus and extensor retinaculum - Answers - Carpal sulcus and flexor
retinaculum
(The passageway between the carpal sulcus and the flexor retinaculum creates the
carpal tunnel through which the median nerve and flexor tendons of the fingers pass.)
Increased quantum mottle results in a decrease in:
1. Spatial resolution.
2. Scatter radiation production.
3. Signal-to-noise ratio.
4. Occupational exposure. - Answers - Signal-to-noise ratio
(Signal-to-noise ratio (S/N) is a measurement of the amount of noise present in a digital
image. Noise can be caused by the imaging equipment (electrical system noise) or by
radiographic technical factors (quantum mottle). An image with little noise present will
have a high S/N.)
The postvoid image is acquired as part of the excretory urogram to:
1. demonstrate the pelvicaliceal system.
2. demonstrate the urethra.
3. check for residual contrast and urine, which might indicate prostate enlargement or
small tumors.
4. check for residual contrast medium and urine in the proximal ureters, which might
indicate hyperfiltration of the kidneys. - Answers - check for residual contrast and urine,
which might indicate prostate enlargement or small tumors.
, (The postvoid image is acquired to check for residual contrast medium and urine in the
proximal ureters, which might indicate prostate enlargement or small tumors. The
postvoid image is taken of the bladder after the patient has emptied his or her bladder.
The pelvicaliceal system and proximal ureters are demonstrated in earlier images of the
urogram. The urethra usually can't be demonstrated unless a voiding cystourethrogram
is performed.)
According to safe injection practices, a medication label should be checked:
1. after selecting the container.
2. while drawing up the medication.
3. just after administration.
4. before discarding the empty container. - Answers - While drawing up the medication
(All medications or solutions drawn into a syringe for injection should be checked 3
times to verify that the correct medication is being administered: when selecting the
container, when drawing up or pouring medication from the container, and when
replacing the container. Expiration dates also should be checked.)
Which of the following statements is TRUE about 14 Fr Foley urinary catheters?
1. The inner diameter is smaller than a 12 Fr Foley catheter.
2. The 14 Fr Foley catheter has a retention balloon on the end.
3. The 14 Fr Foley catheter is considered a straight type of catheter.
4. The 14 Fr Foley catheter is used in female patient catheterization only. - Answers -
The 14 Fr Foley catheter has a retention balloon on the end.
(14 Fr Foley catheters have a retention balloon at the end that is inflated and helps hold
the catheter in the bladder. Catheter French size and lumen diameter have a directly
proportional relationship (a 12 Fr catheter is smaller in lumen diameter than a 14 Fr).
Straight catheters do not have retention balloons. Foley catheters can be used on both
male and female patients.)
When imaging the proximal femur, the top of the image receptor is placed at the level of
the:
1. iliac crest.
2. greater trochanter.
3. anterior superior iliac spine.
4. anterior inferior iliac spine. - Answers - Anterior superior iliac spine
(The top of the image receptor is placed at the level of the anterior superior iliac spine.
Placing the top of the image receptor at the level of the iliac crests places the central ray
and image receptor too proximal on the femur. The other choices would place the
central ray and image receptor too low on the femur, clipping the femoral head and
neck.)
Which of the following is FALSE regarding a patient's health record?
1. The health record is a legal document that is admissible as evidence in court.
2. The Joint Commission requires that all health records be stored electronically if
created after 2010.
3. Health records contain consent and authorization forms.
The inferior and posterior portion of the calcaneus to which the Achilles tendon attaches
