stationary, legs
Begin by determining whether the patient has a _____ side and a ____ side or whether both sides are equal.
strong and weak
The _________ should lift the patient's torso while the other person lifts the patient's feet.
stronger person
Some of the most common positions used in radiographic positioning; ____ ____ & _____.
supine, prone, and lateral.
What term describes the hypothetical point around which all mass appears to be concentrated? a. center of gravity b. base of support c. orthostatic hypotension d. a and b
a. center of gravity
Position the wheelchair at a ____ degree angle so that the patient's ________ is against the table.
45 stronger side
If a patient arrives in a wheelchair and on a sling, which type of transfer is indicated? a. hydraulic lift b. pivot c. standby assist d. cart to table by means of a moving device
a. hydraulic lift
Which of the following is the foundation on which a body rests? a. center of gravity b. base of support c. orthostatic hypotension d. biomechanics
b. base of support
What causes patients to feel lightheaded, queasy, or faint when they stand up quickly from a sitting or supine position? a. increased respiration from the effort of standing b. decreased blood pressure c. increased body temperature
b. decreased blood pressure
the foundation on which a body rests.
base of support
Lifting should be done by _________ . The back should be kept straight or in a position of slightly increased lumbar lordosis.
bending and straightening the knees
the science that applies the laws of physics, specifically the action of forces on bodies at rest or in motion
biomechanics
The patient's feet and knees must be _____ to provide stability, especially for paraplegic and hemiplegic patients who are partially paralyzed and may not be to move or feel sensation in a lower extremity.
blocked
What term is used to describe the drop in blood pressure some patients experience when they stand up quickly? a. center of gravity b. base of support c. orthostatic hypotension d. a and b
c. orthostatic hypotension
How can the base of support be increased? a. standing on one toe b. standing on one foot c. standing with the legs far apart d. bending the knees with the feet together
c. standing with the legs far apart
Understanding the basic aspects of biomechanics can help prevent back injury while promoting safe and effective patient transfers. This is based on a few fundamentals:
Base of support Center of gravity Mobility and stability muscles
What is the minimum number of persons to use for a cart-to-table transfer when no moving devices are available? a. one b. two c. three d. four
c. three
a hypothetical point at which all the mass appears to be concentrated
center of gravity
The patient's center of gravity should be held _________. This provides the best mechanical advantage for lifting.
close to the one performing the transfer
When the patient is moving onto the x-ray table, ______ whenever possible.
cover the table with a sheet
Which of the following transfers can be used to move a patient from a wheelchair to an examination table? a. pivot b. assisted standing c. standby assist d. all of the above
d. all of the above
Where is the human center of gravity located? a. at the center of the diaphragm b. within 1 to 2 inches of the umbilicus c. midway between the hip joints d. at approximately sacral level two
d. at approximately sacral level two
Toward which side should all transfers be initiated? a. left b. right c. patient's weak side d. patient's strong side
d. patient's strong side
A cart-to-table transfer without a moving device is another choice that requires only a ________.
draw sheet.
When standing, the feet and the space between the feet constitute a base of support. Standing with the feet wide apart ______ the base of support. Standing on one foot provides the person with a _____ base of support.
enlarges narrow
When lifting a patient, the person performing the transfer should stand with ______ to increase the base of support
feet apart
_____ results when the center of gravity moves beyond the boundaries of the base. For safe, stable lifting, the center of gravity always must be over the base of support.
Instability
When the patient is ready, both of you _______ until the patient can feel the table against the back of the thighs
pivot toward the table
______ muscles are found in the limbs. They tend to have long white tendons and cross two or more joints.
Mobility
_______ muscles are found in the torso. They are large expanses of red muscle that provide postural support.
Stability
Other devices can also be used such as a _______.
roller device.
For patients who are unable to assist in their move from a cart, gurney, or stretcher onto an x-ray table, the use of ______ ______ or ______ may be required.
a maxi slide, a draw sheet, and thin sheets of plastic
Some patients may be too heavy to lift manually and will require a _____.
hydraulic lift.
Skin breakdown can occur in a brief period of time (1 to 2 hours) and may result in a decubitus ulcer caused by ____ ____ & ____.
immobility, pressure, and shearing force.
The person lifting the patient's torso is usually ______
in charge of the transfer.
Proper body alignment when lifting or transferring a patient includes:
