Study Notes

Body Mechanics

The coordinated use of the musculoskeletal and nervous systems to maintain balance, posture, and body alignment.
The field of physiology that studies muscular actions and the function of muscles in maintaining body posture.

Posture

The position in which someone holds their body while standing, sitting, or lying down.
Determined by the coordination of muscles, proprioception (awareness of body position), and balance.

Center of Gravity

The point where the body's mass is evenly distributed.
In adults, it's located in the midpelvic cavity, between the symphysis pubis and the umbilicus.

Base of Support

The area under an object or person that includes all points of contact with the supporting surface.

Range of Motion

The full movement potential of a joint, typically measured in degrees.

Gait

The manner or pattern of walking, including speed, rhythm, and style of movement.

Importance of Body Mechanics for Nurses

Spinal Disorders: Conditions such as scoliosis, herniated discs, or spinal stenosis can impact posture and movement.
Chronic Pain: Persistent pain can lead to altered movement patterns to avoid discomfort.
Infections: Infections that affect joints or muscles can limit mobility and strength.
Age-related Changes: Decreased muscle mass, bone density, and joint flexibility can affect overall body mechanics in older adults.

Procedures for Client Positioning by Canadian Nurses

Assessment: Evaluate the client's physical condition, mobility, and comfort level.
Promote Alignment: Use pillows to support the head, neck, back, and limbs. Ensure the spine is in a neutral position and joints are properly aligned.
Comfort: Adjust the bed height to facilitate safe positioning. Use appropriate techniques to help the client into a comfortable position (e.g., Fowler's, lateral, or supine).
Prevent Complications: Regularly reposition the client to prevent pressure ulcers and promote circulation. Use pressure-relieving devices like special mattresses or cushions as needed.
Facilitate Procedures: Position the client based on the procedure requirements (e.g., sitting for assessments, side-lying for drainage). Ensure privacy and dignity during positioning, using drapes or curtains as appropriate.
Support and Safety: Use side rails or call bells for safety. Educate the client about the positioning and its importance for their comfort and recovery.
Documentation: Record the positioning and any changes made for continuity of care.

Procedures for Assisting Clients

Progressive Ambulation

Assessment: Evaluate the client's mobility and safety needs.
Preparation: Ensure the environment is clear of obstacles.
Support: Assist the client to a standing position.
Technique: Use a gait belt if necessary; start with short distances, gradually increasing as tolerated.
Encouragement: Provide verbal support and ensure the client maintains a steady pace.

Use of a Cane

Assessment: Determine the client's strength and balance.
Positioning: The cane should be held on the stronger side.
Walking Technique: Instruct the client to move the cane forward, then step with the weaker leg, followed by the stronger leg.
Monitoring: Ensure the client maintains proper posture and balance while walking.

Crutches Walking

Assessment: Ensure the client is instructed on proper crutch use.
Adjustment: Adjust crutches to the client's height (2-3 fingers under armpit).
Technique: Instruct on the tripod position (crutches forward, then step with the affected leg followed by the strong leg).
Support: Monitor the client for stability and provide assistance as needed.

Use of a Walker

Assessment: Ensure the walker is adjusted to the correct height.
Positioning: Instruct the client to stand inside the walker.
Walking Technique: Encourage moving the walker forward, then stepping into the walker with the weaker leg, followed by the stronger leg.
Monitoring: Watch for stability and encourage proper posture.

Use of a Wheelchair

Assessment: Check the client's ability to transfer in and out of the wheelchair.
Preparation: Ensure the wheelchair is locked and positioned close to the bed or transfer surface.
Assistance: Help the client pivot to sit in the chair, using proper body mechanics.
Securing: Ensure safety belts are fastened if applicable, and position footrests properly.
Movement: Guide the client as needed for propulsion or provide assistance in moving the wheelchair.

General Considerations for Assisting Clients

Safety: Always prioritize the client's safety and comfort.
Education: Provide instructions and reassurance throughout each procedure.
Documentation: Record any observations or changes in mobility status.

Operating a Mechanical/Hydraulic Lift Safely

Preparation: Assess the client's weight and mobility needs. Ensure the lift is in good working condition (check for damage or wear).
Set Up: Position the lift close to the client and lock the wheels. Ensure the area is clear of obstacles.
Adjust the Lift: Attach the sling securely according to the manufacturer's instructions. Ensure the sling is appropriately positioned under the client (usually under the shoulders and thighs).
Position the Client: If possible, assist the client into a sitting position. Ensure the client is comfortable and aware of the lift operation.
Lift Operation: Raise the lift slowly, keeping an eye on the client for any signs of discomfort. Ensure that the client is securely in the sling before lifting them off the surface.
Transfer: Move the lift to the desired location (e.g., bed or chair). Lower the client slowly and gently into the new position, ensuring they are stable before detaching the sling.
Post-Transfer: Remove the sling once the client is secure and comfortable. Make sure the lift is returned to its proper storage area and the wheels are locked.
Documentation: Record the transfer process and any observations regarding the client's response or condition.

General Safety Tips for Operating a Mechanical/Hydraulic Lift

Communicate clearly with the client throughout the process.
Follow the specific manufacturer guidelines for the lift being used.

Patient Positioning in Bed

General Preparation: Use lifting devices if available, maintain spinal alignment, and verify healthcare provider orders. Perform hand hygiene, use PPE if needed, and identify and explain the procedure to the patient.
Supported Positions:
- Fowler's position: Raise the bed head to 15-90 degrees, using pillows to support the head, arms, and legs.
- Supine position: The patient lies flat with pillows supporting the back, arms, and legs, and rolls to prevent foot drop.
- Prone position: Turn the patient with assistance, supporting the body, arms, and head, and use pillows under the abdomen and legs.
- Lateral/Side-lying position: Turn the patient onto their side, with pillows supporting the head, arms, and legs, and rolls for foot alignment.
- 30-degree lateral position: Place pillows behind the back and under the legs, adjusting the hip and shoulder for proper alignment.
Post-Procedure: Ensure patient comfort, safety (side rails up, bed lowered), and document the patient’s response.

Assisting with Moving a Patient in Bed

General Safety Measures: Use lifting devices if available, maintain spinal alignment, and raise the bed to a comfortable height. Perform hand hygiene, use proper body mechanics (bend knees, use leg muscles), and ensure bed brakes are locked.
Moving Techniques:
- Using a Drawsheet: Two nurses use a drawsheet to lift the patient by rolling the patient onto their back, positioning the drawsheet under them, and lifting the patient in unison without dragging.
