positioning
up
Plan ahead for activities that require lifting, transfer, and ______ of a client, and ask others to be available to assist.
ambulation
Prepare the ______ by removing obstacles prior to the procedure prior to lifting, transferring, and ambulation. Explain the process to the client and assistants to clarify their roles.
environment
Be aware that the safest way to lift a client is with _______.
assistive equipment
Rest between heavy activities to decrease ________.
muscle fatigue
Maintain ________ and exercise regularly to increase the strength of your arms, legs, back, and abdominal muscles, so these activities will requires less energy.
good posture
Keep your head and neck in a ______with your pelvis to avoid neck flexion and hunched shoulders which can cause impingement of nerves in your neck.
straight line
Use _______ when lifting and moving clients to prevent injury from sudden or jerky muscle movements.
smooth movements

long periods
Avoid ______ movements of the hands, wrists, and shoulders. Take a break every 15 to 20 minutes to flex and stretch joints and muscles.
repetitive
Avoid twisting your ____ or bending at the waist (flexion) to minimize the risk for injury.
spine
________, especially those who are unable to move themselves, so that they maintain good body alignment.
Positioning clients
Frequent position changes prevent discomfort, contractures, ________, and nerve and circulatory damage, and they stimulate postural reflexes and muscle tone.
pressure on tissues
Use pillows, bath blankets, and hand rolls, boots, splints, trochanter rolls, _______, and other aids to maintain proper body alignment.
ankle support devices
Evaluate each situation and use an algorithm to determine the _______ to transfer or move the client. Cane the client bear weight? Can she assist? Is she cooperative?
safest method

transfers
Evaluate the need for _______ staff or assistive devices (transfer belt, hydraulic lift, sliding board).
additional
Assess and monitor the use of ________ (canes, walkers, crutches).

Include assistance or mobility aids in the ______ for safe transfers and ambulation.
plan of care
_____ position is when the client lies supine with the head of the bed elevated 15 to 45 (typically 30)
semi-fowler’s
The _____ position prevents regurgitation of enteral feedings and aspiration by clients who have difficulty swallowing.
semi-fowler’s
____ position promotes lung expansion for clients who have dyspnea or are receiving mechanical ventilation.
semi-fowler’s
_____ position is when the client lies supine with the head of the bed elevated 45 to 60.
fowler’s
_____ position is useful during procedures such as nasogastric tube insertion and suctioning. It allows for better chest expansion and ventilation and better dependent drainage after abdominal sugeries.
fowler’s
The ____ position is when the client lies supine with the head of the bed elevated to 60 to 90.
high-fowler’s
The ___ position promotes lung expansion by lowering the diagphragm and thus helps relieve sever dyspnea.
high-fowler’s
____ position helps prevent aspiration during meals.
high-fowler’s
The _______ position when the client lies on his back with his head and shoulders elevated on a pillow and his forearms on pillows or at his side. A foot support prevents foot drop and maintains proper alignment.
supine or dorsal recumbent
___ position is when the client lies flat on his abdomen and chest with his head to one side and his back in correct alignment.
prone
_____ position promotes drainage from the mouth after throat or oral surgery, but inhibits chest expansion. Its for short term use only.
prone
The ____ position helps prevent hip flexion contractures following a lower extremity amputation.
prone
The _____ position is when the client lies on his side with most of his weight on the dependent hip and shoulder and his arms in flexion in front of this body. He should have a pillow under his head and neck, his upper arms, and his legs and thighs to maintain body alignment.
later or side-lying
The _____ position is a good sleeping position, but the client needs turning regularly to prevent the development of pressure ulcers on the dependent areas. A 20 lateral position is essential for clients at risk for pressure ulcers.
later or side-lying
The _____ position is when a client is on his side halfway between lateral and prone positions, with his weight on his anterior ileum, humerus, and clavicle. His lower arm is behind him while his upper arm is in front. Both legs are in flexion but the upper leg is flexed at a greater angle than the lower leg at the hip as well as at the knee.
sims or semi-prone
The _____ position is a comfortable sleeping position for many clients and it promotes oral drainage.
sims or semi prone
____ position is when the client sits in the bed or at the bedside with a pillow on the overbed table, which is across the client’s lap. He rests his arms on the overbed table.
orthopneic
_____ position allows for chest expansion and is especially beneficial for clients who have COPD.
orthopneic
The _____ position is when the entire bed is tilted with the head of the bed lower than the foot of the bed.
trendelenburg
The ____ position facilitates postural drainage and venous return.
trendelenburg

reverse trendelenburg
The _____ position promotes gastric emptying and prevents esophageal reflux.
reverse trendelenburg
The ______ position is when the client remains flat with his legs above the level of his heart.
