NCLEX-RN® Mobility and Immobility: Complications of Bedrest, Therapeutic Positioning, and Rehabilitation
Mobility nursing for the NCLEX-RN®: hazards of immobility (DVT, pneumonia, pressure injuries), safe positioning for conditions, assistive device use, and rehab priority nursing interventions.
The big picture
Mobility is essential for physical and psychological health — and immobility is one of the most serious risks in hospitalized patients. NCLEX-RN® tests the nurse's ability to identify complications of bedrest before they occur, position patients correctly for their condition, and promote safe early mobilization. The underlying principle is simple: if the patient can move, help them move.
Complications of immobility
Every body system suffers during prolonged immobility. These complications are preventable with good nursing care.
By system — what to watch for and prevent
| System | Complication | Prevention |
|---|---|---|
| Cardiovascular | DVT/PE, orthostatic hypotension | SCDs, anticoagulation if ordered, early ambulation, leg exercises |
| Respiratory | Hypostatic pneumonia, atelectasis | Incentive spirometry, deep breathing, repositioning every 2 hours, early ambulation |
| Integumentary | Pressure injuries | Reposition every 2 hours, skin inspection, pressure-redistributing surface |
| Musculoskeletal | Muscle atrophy, joint contractures, foot drop, disuse osteoporosis | ROM exercises (active or passive), positioning, splints/footboards |
| GI | Constipation, ileus | Adequate fluids and fiber, ambulation, stool softeners |
| Urinary | Urinary retention, UTI, renal calculi | Adequate hydration, upright positioning for voiding, catheter care |
| Psychological | Depression, anxiety, disorientation, sleep disturbance | Stimulation, social interaction, consistent routine, natural light |
| Metabolic | Negative nitrogen balance (muscle protein breakdown), hypercalcemia from bone resorption | Early nutrition support, weight-bearing exercises |
DVT — the most urgent cardiovascular complication
Risk factors: Virchow's triad (venous stasis, hypercoagulability, endothelial injury) — immobility is the stasis component.
Signs of DVT: Unilateral leg swelling, warmth, redness, tenderness (Homans' sign — calf pain on dorsiflexion — is not reliable but may still be referenced on NCLEX®).
Priority actions: Notify provider. Doppler ultrasound to confirm. Prepare for anticoagulation.
Prevention:
- Sequential compression devices (SCDs) — applied to both legs; ensure they fit properly and are worn continuously except during ambulation
- Anticoagulants as ordered (heparin, enoxaparin)
- Early ambulation — the most effective single intervention
- Leg exercises when immobile: ankle pumps, quadriceps sets, knee bends
Pulmonary embolism — from DVT
A DVT can dislodge and travel to the pulmonary vasculature. If a patient with a known or suspected DVT suddenly develops chest pain, dyspnea, and tachycardia → suspect PE.
Critical safety rule: Never massage a leg with a known or suspected DVT — can dislodge the thrombus.
Foot drop
Foot drop (inability to dorsiflex the foot) results from peroneal nerve compression in patients who lie with feet in plantarflexion for extended periods.
Prevention:
- Use footboards or splints to keep the foot in a neutral (90-degree) position
- Perform ROM exercises at least 2–3 times daily
- Avoid sustained plantar flexion (feet falling forward)
Note: Once foot drop occurs, it can be permanent. Prevention is the only cure.
Contractures
A contracture is permanent shortening of a muscle, tendon, or joint capsule due to prolonged immobility or spasticity. Common sites: hip, knee, elbow, fingers, shoulder.
Prevention:
- Range of motion exercises — passive ROM if patient cannot perform active ROM
- Proper positioning (neutral, aligned)
- Splints as ordered (wrist, hand, ankle)
- Early physical therapy referral
Range of motion exercises
| Type | Patient involvement | When used |
|---|---|---|
| Active ROM | Patient moves the joint independently | Patient can move but is deconditioned |
| Active-assistive ROM | Nurse/PT assists the patient's own movement | Partial strength |
| Passive ROM | Nurse moves the joint for the patient | Patient cannot move at all (paralysis, coma) |
Principles:
- Support joints above and below the joint being exercised
- Move through full range until resistance — stop at pain
- Perform at least twice daily during all interactions if the patient is immobile
- Gentle and slow — never force past resistance
Therapeutic positioning
Positioning protects the airway, prevents complications, and promotes comfort. NCLEX® tests which position is correct for which condition.
Positioning quick reference
| Condition | Position | Rationale |
|---|---|---|
| Respiratory distress / dyspnea | High Fowler's (90°) | Maximizes lung expansion |
| Semi-Fowler's | 30–45° | Prevents aspiration during tube feeding; post-op recovery |
| Left lateral (Sims') | Left side-lying | Post-seizure, enema administration, unconscious patient |
| Dorsal recumbent | Supine with knees bent | Abdominal assessment, catheter insertion |
| Lithotomy | Supine, legs in stirrups | Gynecologic procedures |
| Trendelenburg | Head down, feet up | Cord prolapse, shock (controversial for hemodynamic support) |
| Reverse Trendelenburg | Head up, feet down | Reflux/GERD, some bariatric care |
| Prone | Face-down | ARDS (improves oxygenation); burns on posterior trunk; lumbar surgery |
| Lateral | Side-lying | Prevents aspiration; pressure relief from sacrum |
| 30-degree lateral tilt | Neither flat on side nor flat supine | Best for pressure injury prevention over trochanter |
| Post-hip replacement (posterior approach) | Avoid hip flexion > 90°, internal rotation, adduction | Prevents prosthesis dislocation |
Spinal cord injury positioning
- Log-roll technique: Move the patient as one unit, keeping head/neck/spine aligned during repositioning
- Use a minimum of 3 people for log-rolling; one stabilizes the head, one the trunk, one the legs
- Do not twist or flex the spine
Trendelenburg controversy
The Trendelenburg position (head down) is no longer routinely recommended for hypotensive patients — it provides minimal benefit and risks aspiration. Passive leg raise (raising both legs to 45 degrees) is the preferred alternative for improving venous return.
Early ambulation
Early ambulation is the single most effective nursing intervention for preventing most complications of immobility.
Protocol principles
- Begin ambulation as soon as the patient's condition and orders allow
- Assess orthostatic BP before the first ambulation after prolonged bedrest
- Have the patient sit at the edge of the bed (dangle) for several minutes before standing
- One or two-person assist as needed; have a gait belt for safety
- Stop if: Dizziness, chest pain, pallor, diaphoresis, O₂ saturation drops, patient is too fatigued
Progressive ambulation goals
| Day | Goal |
|---|---|
| Day 1–2 | Dangling at bedside; sitting in chair for meals |
| Day 2–3 | Stand and pivot; walk to bathroom with assist |
| Day 3+ | Walk in the hallway; increase distance daily |
Rehabilitation nursing concepts
Goals of rehabilitation
- Restoration of function to the highest possible level
- Prevention of further disability
- Maintenance of current function
Interdisciplinary team roles
| Discipline | Focus |
|---|---|
| Physical therapy (PT) | Gait, transfers, balance, strengthening, ambulation |
| Occupational therapy (OT) | ADLs — dressing, bathing, grooming, adaptive equipment |
| Speech-language pathology (SLP) | Swallowing, communication, cognitive rehabilitation |
| Social work | Discharge planning, community resources, family support |
| Nursing | 24-hour care, reinforcing therapy goals, skin integrity, medications |
Transfer techniques
Bed to chair:
- Position wheelchair at a 45-degree angle to bed, on the patient's stronger side
- Patient sits at edge of bed; assess orthostatic tolerance
- Non-slip footwear on
- Gait belt applied
- Pivot on stronger leg to chair
Mechanical lift (Hoyer):
- Use for patients who cannot bear weight or assist
- Two nurses ideally; follow equipment-specific protocol
- Sling properly positioned under the patient before lifting
NCLEX® clinical judgment focus
Common immobility questions:
- Which patient is at highest risk for a complication of immobility? (Bedfast > ambulatory; older adult > younger)
- Which intervention prevents DVT? (SCDs, leg exercises, early ambulation, anticoagulants)
- Which position for this diagnosis? (Use the chart above)
- Which finding indicates a complication? (Calf swelling = DVT; sudden chest pain = PE; fever + cough = pneumonia)
Common NCLEX® traps:
- Massaging a leg with suspected DVT — contraindicated
- Using Trendelenburg for hypotension — no longer standard; use passive leg raise
- Not dangling before ambulation — orthostatic hypotension causes falls
- Performing ROM past the point of pain — stop at resistance, never force
FAQ
What is the most effective nursing action to prevent complications of immobility?
Early mobilization and ambulation — when the patient's condition allows. This single intervention prevents DVT, pneumonia, pressure injuries, muscle atrophy, constipation, and orthostatic hypotension simultaneously.
What is a sequential compression device (SCD) and who should use it?
SCDs are inflatable sleeves applied to the lower legs that intermittently compress and release, mimicking the pumping action of walking muscles. They are used for DVT prevention in immobile patients — surgical, medical, and trauma. They should be worn continuously except during ambulation, hygiene, and skin checks.
When is passive ROM performed?
When the patient is completely unable to move a limb independently — including unconscious patients, quadriplegic patients, and those in the immediate post-acute phase after stroke. The nurse moves all joints through their full range of motion to prevent contractures.
Why is dangling before standing important?
After prolonged bedrest, the cardiovascular system cannot quickly compensate for the hydrostatic shift of blood to the lower extremities when standing. Sitting at the edge of the bed (dangling) allows a gradual adjustment and prevents orthostatic hypotension and falls.
What is the 30-degree lateral tilt and why is it preferred over side-lying?
Fully side-lying puts all pressure directly on the greater trochanter, a bony prominence highly susceptible to pressure injury. The 30-degree lateral tilt positions the patient at a 30-degree angle from supine, with a pillow support — redistributing pressure away from the trochanter to more padded tissue areas. It is recommended for patients at high pressure injury risk.
Key takeaways
- Complications of immobility: DVT, PE, pneumonia, pressure injuries, contractures, foot drop, constipation, UTI, depression. All preventable with proactive nursing care.
- Most effective prevention: Early ambulation. SCDs for DVT. Repositioning every 2 hours for skin. Incentive spirometry for lungs. ROM exercises for joints.
- Never: Massage a leg with suspected DVT. Force ROM past pain. Skip dangling before first ambulation.
- Positioning: High Fowler's = respiratory distress. Left lateral = unconscious/seizure. 30-degree lateral tilt = pressure injury prevention.
