Questions and CORRECT 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 - CORRECT ANSWER - 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. - CORRECT ANSWER - 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 - CORRECT ANSWER - 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. - CORRECT ANSWER - 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 proximal tibiofibular joint is classified as a ________________ joint.
1. fibrous pivot
2. synovial ellipsoid
3. fibrous syndesmosis
4. synovial gliding - CORRECT ANSWER - Synovial gliding
(The proximal tibiofibular joint is a synovial gliding joint that is freely movable. The distal
tibiofibular joint is a syndesmosis type of fibrous joint that is immovable or slightly movable.)
The ________ vein is MOST pronounced and superficial on the radial side of the dorsal aspect
of the wrist when a tourniquet is applied.
1. median cubital
2. ulnar
3. radial
4. cephalic - CORRECT ANSWER - Cephalic
(The cephalic vein can be used for venipuncture. The median cubital vein is not in the antecubital
space. The ulnar vein is on the opposite side of the radial side. The radial vein is a much deeper
vein that courses closer to the middle of the forearm.)
________ BEST measures the threshold occurrence of deterministic effects.
1. Absorbed dose
2. Equivalent dose
3. Effective dose
