Chapter 5: Foundational Ultrasound Ergonomics for Obstetrics and Gynecology Flashcards
any behavior that increases the chances of developing MSKD
risk factor
the creation of a safe workplace that involves the sonographer and ultrasound system positioning
ergonomics
movement beyond the normal range or a joint
hyperextension
a position that increases the angle of a joint
extension
the position of our bodies
posture
fixed or unchanging position
static posture
excessive anterior curvature of the spine
lordosis
work area encompassing the equipment
workstation
repeated movements. When coupled with force and awkward body positions increase the risk of MSKD development
repetition
the decrease of an angle of a joint
flexion
cumulative injury caused by repeated movement of a musculoskeletal structure
repetitive stress injury
moving away from the center of the body
abduction
body position without flexion or extension
neutral position
Musculoskeletal disorders involve all except injury to the:
a. ligaments
b. acromion
c. tendons
d. nerves
b
The most common location for WRMSK pain in a sonographer involves the:
shoulder
A chronic work injury displays these signs:
a. aching, fatigue, stiffness, muscle or joint discomfort, and pain
b. aching, fatigue, stiffness, muscle or joint discomfort
c. aching, fatigue, stiffness, muscle or joint discomfort, pain, plus weakness or inability to hold objects
d. aching, fatigue, stiffness, muscle of joint discomfort, and headache
c
One of the largest risk factors for MSKD is:
an awkward body position
The ultrasound system monitor should be positioned approximately ____ inches from the sonographer’s face and eyes.
40
Transducer cable twisting and weight can cause torque on a sonographer’s wrist. Select the best way to remedy wrist torque.
a. use cable supports
b. adjust control panel height
c. adjust chair height
d. rotate the monitor
a
Choose the correct ergonomic statement.
a. Limit portable examinations that require static or awkward positions and forceful transducer handling
b. maintain scanning position
c. schedule like exam types together
d. use similiar motions for each examination
a
Choose the correct wrist position for maintaining a healthy ergonomic position.
a. radial deviated
b. neutral
c. ventrally flexed
d. dorsally extended
b
Select a cause for an unhealthy forceful transducer grip:
a. patient breathing
b. decreased carpal muscle integrity
c. lighter equipment
d. patient obesity
d
Choose the correct suggested rest break to relieve muscle tension and increase joint and muscle flow during an extended ultrasound examination:
a. 1 minute break every 10 minutes
b. 30 to 60 second mini break every 20 minutes
c. 1 minute break every hour
d. 30 second mini break every 5 minutes
b
MSKDs are the result of accumulated _____ over a prolonged time.
trauma
WRMDKD means:
work related musculoskeletal disorder
Patient ____ has led to the use of increasing axial force to acquire diagnostic images.
obesity
Most ultrasound systems allow for independent monitoring positioning, _____, ______, and ______, providing a method to decrease neck flexion and extension.
tilt
angle
rotation
It is known that WRMSKDs are a ______ process involving both personal and work behaviors.
cumulative
With the overuse of the wrist, swelling occurs, compressing nerves and tendons, increasing the risk of developing _____ and _____.
carpal tunnel syndrome
deQuervian syndrom
The most ergonomic sitting position is when the forearms and thighs are _____ to the floor.
parallel
When sitting to perform an ultrasound examination, the feet should be ____.
flat
To decrease the chance of developing back pain while scanning, maintain ______ spine alignment.
neutral
Features of an ergonomic chair that will aid with controlling work injuries are ______, _______, and _______.
adjustable height
lumbar support
swivel of chair and back
Work tasks that increase the potential for muscular injury
force
vibration
body positions
contact pressure
repetitive movements
temperature
Demands out of sonographer’s control in the workplace
lack of control over job tasks
increased production demands
communication failures
missing task variety resulting in boredom
inability of management support
job insecurity
Horizontal zone
close to your body allowing for approximately a 45-degree medial and lateral rotation of the arm
Vertical zone
located between 80 and 100 degrees of elbow flexion
