BNS Section 5: Mobility

Section Overview

Mobility is a fundamental human need, and its disruption — whether from illness, injury, surgery, or age-related decline — carries serious consequences including pressure injuries, deep vein thrombosis, pneumonia, muscle atrophy, contractures, deconditioning, and falls. Nurses play a central role in preserving, restoring, and safely supporting mobility across every care setting.

This section covers the clinical knowledge and technical skills required to move, position, and ambulate patients safely while protecting both patient and nurse from injury. Safe patient handling and mobility (SPHM) principles, evidence-based fall prevention, therapeutic positioning, and range-of-motion exercise are covered in depth.

Safe Patient Handling and Mobility (SPHM)

Why SPHM Matters

Musculoskeletal injuries — particularly to the low back — are the leading cause of occupational injury among nursing professionals. Manual patient handling is the primary contributor. The American Nurses Association (ANA) and OSHA recommend that no healthcare worker manually lift more than 35 lbs (16 kg) of a patient’s body weight under any circumstances. Exceeding this threshold places both the patient (at risk for injury from dropped transfers or poor positioning) and the nurse (at risk for cumulative musculoskeletal damage) in danger.

Assistive Device Selection

Patient Condition	Recommended Assistive Device
Full weight-bearing with good balance	Gait belt + standby assistance
Partial weight-bearing or impaired balance	Stand-assist device or stand-pivot lift
Non-weight-bearing or fully dependent	Full-body mechanical lift (sling lift)
Lateral transfer (bed to stretcher)	Friction-reducing slide sheet or lateral transfer board
Bariatric patient	Bariatric-rated equipment per facility policy

General Body Mechanics

Even when using assistive devices, correct body mechanics protect the nurse:

• Face the direction of movement; avoid twisting at the waist
• Keep the patient close to the body; widen the base of support
• Use leg muscles, not the back, to generate lifting force
• Lower the bed to working height before initiating any transfer or care activity
• Communicate with the patient and care team before and during movement (“on my count of three”)

Transfer Techniques

Pivot Transfer with Gait Belt (Partial Weight-Bearing)

1. Explain the procedure; assess patient’s ability and weight-bearing status
2. Apply the gait belt at the waist, over clothing, snugly enough that two fingers slide underneath
3. Lower the bed to the lowest safe height; lock wheels on bed and wheelchair
4. Move the wheelchair to the patient’s stronger (unaffected) side, angled at 45°
5. Assist the patient to a sitting position at the edge of the bed (dangle); allow 1–2 minutes to assess for orthostatic hypotension
6. Grasp the gait belt at the patient’s sides; block the patient’s weak knee with your knee
7. On the count of three, assist the patient to standing; pause to confirm stability
8. Pivot toward the wheelchair; ensure the patient can feel the chair behind their legs before lowering
9. Lower the patient slowly until buttocks contact the seat; ensure safety before releasing the gait belt

Mechanical Full-Body Lift (Non-Weight-Bearing)

1. Select the correct sling size and type (seated, hammock, or ambulation sling per patient needs)
2. Position the sling under the patient while supine (log-roll technique)
3. Attach sling loops to the lift bar per manufacturer color-coded sequence
4. With a second caregiver present, raise the patient slightly and recheck sling position
5. Move the lift to the destination, lower slowly, position the patient comfortably, detach loops
6. Do not leave a patient suspended in the lift

NCLEX-Style Practice Question:

A nurse is preparing to transfer a patient with left-sided hemiplegia from the bed to a wheelchair. Where should the nurse position the wheelchair?

• A) On the patient’s left (affected) side
• B) On the patient’s right (unaffected) side ✓
• C) Directly in front of the patient
• D) Behind the patient to provide back support

Patient Positioning

Correct positioning promotes comfort, prevents pressure injury, maintains body alignment, optimizes respiratory function, and prevents complications. The nurse selects and documents therapeutic positions based on patient condition and goals of care.

Common Therapeutic Positions

Position	Description	Clinical Indications
Supine (dorsal recumbent)	Lying flat on the back; pillow under head; small pillow under knees optional	Post-procedure recovery, spinal precautions (modified), sleep
Fowler’s (high)	Head of bed at 90°; knees may be slightly elevated	Eating, acute dyspnea, post-op airway management
Semi-Fowler’s	Head of bed at 30–45°; slight knee elevation	Sleeping, aspiration prevention, most post-operative patients, enteral feeding
Lateral (side-lying)	On the side with top knee flexed; pillow between knees; support head and top arm	Pressure relief from sacrum, post-op comfort, ear drainage
30° Lateral Tilt	A modified side-lying position that avoids direct pressure on the greater trochanter	Pressure injury prevention for high-risk patients
Prone	Lying face down; pillow under abdomen and ankles	ARDS (prone positioning therapy); rarely used in routine care
Trendelenburg	Bed tilted head-down; feet elevated	Hypotension (limited evidence; used cautiously); postural drainage (historical)
Reverse Trendelenburg	Bed tilted with head elevated and feet lowered	GERD; patients for whom aspiration risk is elevated but who cannot tolerate standard Fowler’s

Positioning Principles

• Change position at minimum every 2 hours for immobile patients
• Document each position change, including time and skin assessment findings
• Support all joints in functional alignment; use pillows, foam wedges, or positioning aids as needed
• Do not position a patient directly on a bony prominence or an existing pressure injury

Range-of-Motion (ROM) Exercises

Range-of-motion exercises preserve joint flexibility, stimulate circulation, and prevent contracture formation in patients with limited mobility. They are initiated early in hospitalization and are a nursing responsibility.

Types of ROM

Type	Who Performs the Movement	When Used
Passive ROM	Nurse moves the joint completely; patient provides no effort	Unconscious, paralyzed, or fully dependent patients
Active-Assistive ROM	Patient and nurse share effort	Patients with weakness or limited movement ability
Active ROM	Patient moves independently through full range	Patients with preserved strength; conducted for monitoring

ROM Technique Principles

• Support the joint proximal to the one being moved (e.g., support the elbow while moving the wrist)
• Move each joint through its full range of motion slowly, smoothly, and rhythmically
• Stop immediately if the patient reports pain; do not force range of motion
• Complete a full set (all joints) at minimum once per shift for passive ROM patients
• Document ROM exercises performed, joints included, and patient tolerance

Joint Movements (Key Terminology)

• Flexion / Extension — decreasing / increasing the angle at a joint
• Abduction / Adduction — moving away from / toward the body’s midline
• Internal / External Rotation — rotating toward / away from the body’s center
• Supination / Pronation — turning the palm upward / downward
• Inversion / Eversion — turning the sole inward / outward (foot)
• Circumduction — moving in a circular arc (shoulder, hip)

Fall Prevention

Falls are the most common adverse event in hospitalized patients and the leading cause of injury-related death in adults over 65. Approximately one-third of adult inpatients are at significant fall risk, and up to 30% of in-hospital falls result in injury. Fall prevention is a nurse-sensitive quality indicator.

Fall Risk Assessment

Use a validated, facility-approved tool at admission and with any change in patient status:

• Morse Fall Scale — evaluates fall history, secondary diagnosis, ambulatory aid, IV access, gait, and mental status; score ≥ 45 = high risk
• Hendrich II Fall Risk Model — incorporates confusion, symptomatic depression, altered elimination, dizziness, gender, antiepileptics, and benzodiazepines

High-Risk Interventions (Multifactorial Approach)

• Visual alerts: Yellow non-slip socks, yellow armband, fall-risk sign on the room door
• Environment: Call light within reach at all times; bed in lowest position and locked; clear pathway to bathroom; remove unnecessary equipment
• Monitoring: Bed/chair alarm activated for high-risk patients; hourly safety rounding
• Toileting: Timed toileting program (offer every 2 hours); respond immediately to toileting requests
• Medication review: Identify and report high-risk medications (opioids, sedatives, antihypertensives, diuretics, antiepileptics, benzodiazepines)
• Orthostatic BP monitoring: Measure blood pressure supine and after standing for patients on antihypertensives or those with dizziness
• Patient and family education: Teach the patient to call for assistance; explain fall risks and prevention strategies

NCLEX-Style Practice Questions:

1. A nurse enters a patient’s room and finds the patient attempting to get out of bed unassisted. The patient is 72 years old, taking hydrochlorothiazide and lorazepam, and has a Morse Fall Scale score of 55. Which intervention is the highest priority at this moment?

   • A) Document the attempted self-transfer in the incident report
   • B) Stay with the patient and assist them safely to the bedside commode ✓
   • C) Reapply the bed alarm and remind the patient to call for help
   • D) Apply a vest restraint to prevent further attempts

2. A nurse is ambulating a postoperative patient for the first time after surgery. The patient suddenly states, “I feel dizzy.” What is the nurse’s priority action?

   • A) Encourage the patient to continue — dizziness will resolve with activity
   • B) Return the patient to bed immediately
   • C) Lower the patient to the floor in a controlled manner and call for assistance ✓
   • D) Have the patient sit down in the hallway

Progressive Ambulation

Early mobilization following illness, injury, or surgery improves respiratory function, prevents deconditioning and deep vein thrombosis, and accelerates recovery. Progressive ambulation follows a stepwise approach based on patient tolerance.

Stages of Progressive Ambulation:

1. Dangling at bedside — sit at edge of bed; assess for orthostatic hypotension; ensure the patient is not dizzy before proceeding
2. Standing at bedside — assist to standing; assess weight-bearing and stability before advancing
3. Ambulation in room — short distance with nurse supporting the gait belt; assess gait, balance, and endurance
4. Ambulation in hallway — progressively increased distance as tolerated

Tolerance Assessment During Ambulation:

• Heart rate should not increase more than 20–30 bpm above baseline
• SpO₂ should remain ≥ 90% (or per clinical order)
• Patient should be able to speak in short sentences without stopping to breathe
• Skin color and diaphoresis are assessed continuously
• Stop and return to bed or chair if any of the above tolerance criteria are not met
