RAD 113 Test 2 Study Guide
A component of physics, the laws of Newtonian mechanics, to living bodies at rest and in motion.
The foundation on which a body rests or stands.
- Base of support
A hypothetical area of the body where the mass of the body is concentrated; gravity works from this area.
Center of gravity
Where is your center of gravity?
Second sacral segment
What type of muscles are extremity muscles classified as?
Should be used for lifting?
What type of muscles are the muscles of the torso classified as?
Should be used for support
Sudden drop in blood pressure in the brain when a person stands up quickly from a sitting or supine position; when the oxygen in the brain drops and the person becomes dizzy and prone to fall.
When lifting, the back should be kept straight or in a position of slightly increased __________.
When transferring a patient, what is one thing that must be checked before executing the transfer?
Check the patient's chart to see if they have a restricted weight-bearing status
May overestimate their transfer abilities and require assistance.
Patients with cognitive impairments
Example of a cognitive impairment.
Using a __________ is a good practice when planning to perform transfers.
Symptoms of orthostatic hypotension.
- Blurred vision
- Slurred speech
Ways to minimize the severity of orthostatic hypotension.
- Have patient stand slowly
- Encourage patient to talk during the transfer by asking simple questions
May occur going from one surface type to a different surface type during transfer. Can be caused by several mechanical factors.
Immobilization devices is used for a lateral chest film on a nonambulatory patient?
Can also be used for compression.
Four types of wheelchair transfers.
- Standby and assist
- Assisted standing pivot
- Two-person lift
- Hydraulic lift
Used for patients who have the ability to transfer from a wheelchair to a table on their own.
In standby assist transfers, what angle should the wheelchair should be positioned to the table?
The type transfer used when patients cannot transfer independently but can bear weight on their legs
Assisted standing pivot
Transfer used when a patient cannot bear weight on their legs in order to move from the wheelchair to the table.
Used for transferring heavy patients.
Hydraulic lift techniques
What should a patient be seated on before using a hydraulic lift?
Is critical to lift success.
Type transfer that usually requires 3 people.
Common recumbent patient positions.
Commonly attached medical equipment which should be checked before moving or positioning a patient.
- Oxygen tubing
- Intravenous lines
- Central lines
- Postsurgical drains
- Urine bags
One of the most significant contributing factors to unacceptable image quality. Can result from voluntary and involuntary patient motion.
Contribute to suboptimum image quality.
Is a relation of harmony and accord between two persons, as between patient and physician.
- Positioning sponges
- Velcro straps
- Head clamps
- Cervical collar
- Spine board
Allow for increased accuracy by supporting the patient or anatomic area of interest.
One of the most common methods of reducing patient motion.
Stretchable cotton fabric in the shape of a sleeve pulled over a fractured extremity before a plaster cast is applied. Good for immobilizing the upper limbs above and behind the child’s head.
Useful for positioning and immobilization devices and can be used in a variety of ways.
Can be used if injury to the thoracic or lumbar spine is involved, as well as injuries to the pelvis, hips, and lower extremities and when multiple injuries in addition to spinal trauma are present.
Most often used spinal trauma traction device.
One of the most effective, simple, inexpensive, and reliable method of restraining or immobilizing a child.
What ages can these restraints accommodate depending on the child's size?
- Pigg-O-Stat Infant Immobilizer
- Pedia-Poser Pediatric Positioning Chair
Examinations the Pigg-O-Stat and Pedia-Poser Pediatric Positioning Chair are useful for.
Upright chest and abdomen
Contour-fitting pad, mold, or sponge with attached
Velcro straps for securing the patient.
Immobilization device that patient can be rotated 360° into 8 different positions. It is durable and made of radiolucent material. It is also limited to patients up to 1 year old.
Octostop Restraint Board
Substances or structures not naturally present but of which an authentic image appears on an image.
Recognition of and entering into the feelings of another person.
Hindrance of an action (movement).
Designed strictly for use in positioning various projections of the skull.
They ensure the reduction of voluntary movement on the part of the patient.
Inflatable plastic cuff that is slipped over the affected limb and inflated to provide stability for transport.
Are designed for use on the lower extremities.
