Immobility
Question | Answer |
---|---|
Which body sys is immune to immobility? | None |
How does immobility disrupt normal metabolic functioning? | Alters Metabolism of C,P,F. Decreased metabolic rate. BMR descreases bc cell E & Ox demands are reduced. Decreases ability to produce insulin & metabolize glucose |
HOw does immobility cause a loss of lean body mass and increases BF%? | When body can't metabolize glucose, it breaks down P stores for E. After P is metabolized, Nitrogen is left. Neg Nitrogen Balance exists when excretion of N from P breakdown more than intake of P. Causes loss of lean body mass, increase BF% |
What happens to BMR in a pt who's immobile that has an infection? | BMR increases as a result of fever or wound healing bc they increase cellular oxygen requirements |
What can you do to prevent metabolic changes in immobile pt? | Nutritional Assessment. Diet high in cals & P. Added Vit C. Some juice for tissue repair & to prevent further breakdown. Dangle feet. Ambulate to increase E requirements & BMR |
How does Diuresis effect fld and electrolyte balances in pt who's immobile? | Bc diuresis is the production and excretion of urine, diuresis causes body to lose electrolytes and affect serum calcium levels |
Define hypercalcemia | Increased calcium in the blood |
How does immobility lead to hypercalcemia? | Immobility increases calcium resorption (loss) from bones. This cuases a release of more calcium into blood circulation. Hypercalcemia can occur if kidneys can't respond appropriately. |
What can you do to prevent fluid and electrolyte imbalances in pt who's immobile? | Watch labs for electrolyte imbalances. Strict I/O (nuns cap, tell family not to discard urine, know mL of all containers) |

Why are pts with DVT at increased risk of developing a pulmonary embolism? | Bc DVT's blood clots |
List gastrointestinal changes in pt that's immobile. | Constipation. Impaction (looks like diarrhea). Descreased Gastric Motility. Loss of Defacation Reflex |
Why or How is pt that's immobile at risk for constipation? | Lack of activity. Hypercalcemia (greater than normal amt of calcium in blood) |

List Urinary changes in pt that's immobile | UTI. Urinary retention. Urinary Stasis. Renal calculi |
Define Urinary Stasis | Stoppage of flow of urine at any level of urinary tract |
Define Renal Canculi | Kidney stones that lodge in renal pelvis and pass through ureters |
Why are pt's that are immobile at risk for Renal Calculi? | Bc Renal Calculi are kidney stones and immobile pts have altered calcium metabolism and resulting in hypercalcemia |
What can you do to prevent Urinary changes in immobile pt? | Increase fl. I/O. Check for bladder distention. Check fo color or urine. Sit upright. Void q3h. Dash diet |
List Psychosocial effects that immobility has on pt | Depressed. Changes in behavior. Changes in sleep-wake cycle. Developmental changes. Decreased coping mechanisms. |
Why would pt that's immobile be depressed? | Normally active, now bedridden. No one visits. Changes in how they view themselves. |
What Behavioral changes would you see in a pt that's immobile? | Acting out. Hostile. Mean. Withdrawn. Passive. |
Developmental changes in pt that's immobile are more common in _ and _. | Very young and Very old |
What can you do to prevent Psychosocial changes in pt that's immobile? | Watch for emotional/behavioral changes. Watch for sleep cycle. Provide stimuli for orientation. Offer books/TV/newspaper. Encourage fam to visit. Place clock/calendar in room. |
To reduce Psychosocial effect on pt that's immobile, you should: | Promote self care activities. Encourage to attend therapy is scheduled. Encourage to put on own clothes, hair, makeup. Extend environment. Allow control over environment. |
List Respiratory changes in pt that's immobile | Decreased lung expansion. Generalized muscle weakness. Stasis or pooling of secretions. Atelectasis. Hypostatic Pneumonia |
Define Atelectasis | Collapse of alveoli from secretions blocking bronchiole or bronchus |
Define Hypostatic Pneumonia | Inflammation of lung from stasis or pooling of secretions (mucus accumulation) |
What can you do to prevent Respiratory changes in pt that's immobile? | Assess for O2 deprivation. Assess Resp status q2h. Turn,cough,& deep breathe q2h. Change position q2h. Incentive Spirometer. Increased fld intake to @ least 2,000cc/day to thin secretions. |
List Musculoskeletal changes in pt that's immobile | Loss of strength & endurance. Muscle atrophy. Bone resorption. Osteoporosis from disuse. Joint contractures. Foot drop. |
Hoare are kidney stones caused by osteoporosis? | Lose calcium from bones in osteoporosis so body releases calcium into system which causes kidney stones |
Immobility affects which muscle the most? | Leg muscles which explains the difficulty older pts have getting out of a chair |
What can you do to prevent musculoskeletal changes in pt that's immobile? | ROME. Splints. Exercise. Ambulate. High top tennis shoes |
What can help prevent Foot Drop? | Hightop tennis shoes. Foot board |
What is the biggest Integumentary concern in pt that's immobile? | Pressure Ulcers |
Define Ischemia | Temporary descrease in blood flow to organ or tissue |
How are Pressure Ulcers formed? | Pt lies or sits on bony prominence too long, the longer the period of ischemia & greater risk of skin breakdown |
