PERCEPTION AND COORDINATION
SENSORY PERCEPTION  Sensory perception- involves the conscious organization and translation of the data or stimuli into meaningful information  Sensory reception- process of receiving stimuli or data  Kinesthetics- awareness of the position and movement of body parts  Stereognosis- ability to perceive and understand an object through its size, shape and texture  Visceral - any large organ within the body Four aspects of sensory process  Stimulus  an agent or act that stimulates a nerve receptor  Receptor- a nerve cell that concerts stimulus to a nerve impulse  Impulse conduction- the impulse travels along nerve pathways to the spinal cord or directly to the brain  Perception- perception, or awareness and interpretation of stimuli happens in the brain where specialized brain cells interpret the nature and quality of the sensory stimuli. The LOC affects the perception of stimuli PROMOTING NORMAL SENSORY PERCEPTION  STRUCTURE and FUNCTION of SENSORY PERCEPTION Sensory Awareness -Reticular activating system-responsible for bringing together information from the cerebellum and other parts of the brain with that obtained from the sense organs Input by senses -Special senses-vision, hearing, smell and taste -Somatic senses-touch, kinesthetics (or proprioceptive) sensation, and visceral sensation  SENSORISTASIS o state of optimum arousal-not too much not too little  ADAPTATION o beyond the point of sensoristasis  AWARENESS o Ability to perceive environmental stimuli and body reactions and to respond appropriately through thought and action.  LIFESPAN CONSIDERATION o Newborn and Infant o Toddler and Preschooler o Child and adolescent o Adult and Older Adult FACTORS AFFECTING SENSORY PERCEPTION  Environment  Previous Experience  Lifestyle and Habits  Illness  Medications  Variations in Stimulation  Sensory deprivation SENSORY ALTERATIONS  SENSORY DEPRIVATION- decrease in or lack of meaningful stimuli  SENSORY DEFICIT- impaired reception, perception, or both, of one or more of the senses.
SENSORY OVERLOAD- occurs when a person unable to process or manage the amount or intensity of the sensory stimuli  Factors:  Increased quality and quantity of internal stimuli  Increased quality and quantity of external stimuli  Inability to disregard stimuli selectively ALTERED SENSORY PERCEPTION FUNCTION  Manifestations of Altered Sensory Perception function  Anxiety  Cognitive Dysfunction  Hallucinations and delusions  Sensory deficits  Depression and withdrawal NURSING PROCESS  ASSESSMENT  Normal pattern identification  Risk identification  Sensory overload Lengthy verbal explanations before the procedure  Room close to the nurses station  Bright lights  Use of ECG monitor, mechanical ventilators, Oxygen ,IV tubes other equipment  Frequent treatments  Sensory deprivation  Private room, eyes bandaged, bedrest, sensory aid not available isolation precautions, few visitors CHARACTERISTICS OF NORMAL SENSORY PERCEPTION  Normal vision-visual acuity at or near 20/20, full field of vision and tricolor vision (red, green and blue)  Normal hearing-auditory acuity of sounds at an intensity of 0 to 25 dB, at frequencies of 125 to 8000 cycles per second  Normal taste- ability to discriminate sour, salty, sweet and bitter  Normal smell-discrimination of primary odours such as musky, floral, pepperminty, pungent  Somatic senses-discrimination of touch, pressure, vibration, position, tickling, temperature and pain State of Awareness
State Full consciousness Disoriented Confused Somnolent Semicomatose Coma 
Description Alert; oriented to time, place, person; understands verbal and written words Not oriented to time, place, or person Reduced awareness, easily bewildered; poor memory, misinterprets stimuli; impaired judgment Extreme drowsiness but will respond to stimuli Can be aroused by extreme or repeated stimuli Will not respond to verbal stimuli PHYSICAL ASSESSMENT  Vision-use of snellen chart to measure visual acuity (or have the client read newspaper, menu or whatever)
 Smell-with eyes closed, have client identify 3 odors, such as coffee, tobacco and cloves, one nostril at a time, while occluding the other nostril  Hearing-whisper numbers in each ear, while occluding the other; ask the client to repeat; perform Weber and Rinne tuning fork test  WEBERS TEST- assesses bone conduction by testing the lateralization (sideward transmission) of sounds.  RINNE TEST- test compares air conduction to bone conduction  Sound conducted by air is heard more readily than sound conducted by bone.  Taste-with eyes closed, have client identify 3 tastes such as lemon, salt, and sugar, waiting 1 minute and giving sips of water in between.  Somatic sensations-Test light touch of extremities with a wisp of cotton; test sharp and dull sensation using the point and blunt end of a pin; test two-point discrimination using two pins held close together; test hot and cold sensation using test tube filled with warm and cold water; test position sense by moving the clients fingers or toes Diagnosing  Disturbed sensory perception  Risk for injury  Impaired home maintenance  Risk for impaired skin integrity  Impaired verbal communication  Self care deficit  Social isolation Planning  The overall outcome criteria for clients with sensory-perception alterations are to:  Maintain the function of existing senses  Develop an effective communication mechanism  Prevent injury  Prevent sensory overload or deprivation  Reduce social isolation  Perform ADLs independently and safely IMPLEMENTATION  HEALTH PROMOTION  Client Teaching  Procedure preparation  Nurse-client Interaction NURSING INTERVENTIONS for ALTERED SENSORY PERCEPTION FUNCTION  Stimulation Provision  Stimulation Reduction  Sensory Aids  SENSORY AIDS  VISION o Eyeglasses with proper prescription, clean and in good repair o Adequate room lighting, drapes open o Sunglasses or window shades to reduce glare o Literature with large print o Uncluttered environment, no furniture arrangement o Clock with large numbers o Telephone dial with large numbers o Magnifying glass o Bright, contrasting colors in environment  Hearing o Hearing aid in good repair with working battery o Speaking slowly and distinctly in clients full view, no mouth covering or gum chewing

COORDINATION ACTIVITY, MOBILITY AND EXERCISE Definition:  Body Mechanism  Activity  Exercise  Body mechanics  is the safe use of muscles of the body to accomplish mechanical task Principles of Body Mechanism  Bend knees to lift objects form the floor  Use a wide base of support by placing the feet 12-18 inches apart when moving objects  Pulling is easier than pushing  Work is best accomplished at the center of gravity.  Working at the waist level is most efficient. APPLIED PRINCIPLES OF BODY MECHANICS  Hold objects close to the body when lifting  Use rhythmic, smooth, and coordinated motions at a reasonable speed  Use elbows, hips and knees as levers when lifting  Use mechanical devices when appropriate  Holding the breath during a physical activity is an indication of muscle strain and inefficient use of body mechanics  Adjust the height of the work area when possible  Assume a starting position that will permit freedom of movement in range, direction and position  Keep body balanced over the base of support with knees relaxed and trunk erect (in relation to the pelvis)  Bend hips and knees to alter position of body, widening the base of support as needed, for effective leverage and use of energy  Face the direction of motion, using the muscles of the lower extremities and shifting body weight for lifting, pushing and pulling actions PRINCIPLES OF BODY MECHANICS  Reducing friction between the object moved and the surface on which it moved requires less energy  Holding an object close to the body requires less energy than holding it farther away  Muscle strain can be avoided by using the strong leg muscles when lifting, pushing and pulling  Smooth continuous movements are easier and safer than sudden, sharp or uncontrolled movements  Using rhythmic movements at normal speed requires less energy  Diet  a balance diet is important in maintaining the bones or muscles for optimum activity should be contain adequate sources of calcium, phosphorus and vitamin D for bone growth and prevention of osteoporosis. The diet should contain adequate sources of the following;  Calcium  for bone and teeth formation, blood clotting, muscle activity and nerve function.  High Calcium  dried and fresh dilis, dried and fresh alamang, fried fish, shell fish, certain fresh fishes such as silinyasi, tunsoy, milk, cheese, ice cream, soy beans, monggo and other dried beans, leafy vegetables.  Low Calcium  cereal and cereal products without milk, fruit and fruit juices, vegetables, lean meat. Poultry sugar starchy roots and tubers, young coconut.
Phosphorus  for bone and teeth formation, important in energy transfer, component of nucleic acid.  High Phosphorus  Meat, fish, poultry, egg yolk, milk, cheese, beans and bean products, nuts and seeds, dried banana and flowers, cocoa, chocolate, undermilled rice, pinipig, whole grain cereal, cookies and sweet made with nuts. Low Phosphorus  Egg white, sugar, fats and oil, fruits, kaong, gabi stem, sayote, bihon, sotanghon, kusinta and nata de coco  Vitamin D  promotes Calcium and Phosphorus use normal growth and bone and teeth formation. o Sources  Fishes, liver oils, butter, cream, clams, oyster, eggs, salmon, sardines, Vitamin D fortified foods, milk, margarine

Tone Muscle tone is assessed by putting selected muscle groups through passive range of motion. The most commonly used maneuvers for the upper extremities are flexion and extension at the elbow and wrist. The most commonly used maneuvers for the lower extremities are flexion and extension at the knee and ankle. PHYSICAL ASSESSMENT  Muscle Strength Grading 0 No contraction 1  Slight contraction, no movement 2  Full range of motion without gravity 3  Full range of motion with gravity 4  Full range of motion , some resistance 5  Full range of motion, full resistance  Stretch or Deep Tendon Reflexes a brisk tap to the muscle tendon using a reflex hammer produces a stretch to the muscle that results in a reflex contraction of the muscle. The muscles tested, segmental level, and grading of DTR's is listed below. Grading DTR's 0  Absent 1  Decreased but present 2  Normal 3  Brisk and excessive 4  With clonus  Laboratory Findings  Blood Test  ESR (elevated in SLE and arthritis)  Rheumatoid factors (+in rheumatoid arthritis)  Lupus erythematosus cells (LE cells)  Antinuclear antibodies (ANA) (+ in rheumatoid arthritis)  Uric Acid (elevated in gout)  Anti-DNA (+ in SLE)  C  reactive protein (+ in rheumatoid arthritis)  Uric Acid (elevated in gout) Nursing Assessment Laboratory findings
Minerals Calcium o Decreased levels in osteomalacia, osteoporosis. o Increased levels in bone tumors, healing fractures, Pagets disease  Alkaline Phosphatase o Elevated levels in bone cancer, osteoporosis, osteomalacia, Pagets disease.  Phosphorus o Increased levels in healing fractures, bone tumors  Muscle Enzymes o Aldolase  Elevated in muscle dystrophy, dermatomyositis.  CK (Creatine Phosphokinase) o Elevated in traumatic injuries  LDH (Lactic Dehydrogenase) o Elevated in skeletal muscle necrosis, extensive cancer.  X-ray (Roentgenography) o Done primarily to detect bone fractures.  Bone Scan o Measure radioactivity in bone 2 hrs. after IV injection of a radio isotope; detects bone tumors, osteomyelitis.  Arthroscopy o Insertion of fiberoptic scope into a joint to visualize it, perform biopsy or remove loose bodies.  Arthrocentesis o Removal of synovial fluid, blood or pus from the joint.  Electromyography (EMG) o Measures and records activity of contracting muscles in response to electrical stimulation; helps differentiate muscle disease from motor neuron dysfunction. IMPLEMENTATION  Health Promotion  Physical Fitness Program  Osteoporosis Prevention  Injury Prevention NURSING INTERVENTIONS for ALTERED MOBILITY  POSITIONING  Think through the task before beginning  Ensure that all needed equipment is within reach  Explain to the client exactly what will happen before the beginning of position change  Enlist the clients assistance whenever possible, giving instructions and encouragement as necessary  When the position change has been completed, ask if the client is comfortable. Reposition as necessary  Tell the client how long he or she will remain in the position. Provide a call device within reach. Document position changes and the clients tolerance.  JOINT MOBILITY MAINTENANCE  Types of ROM  General Principles of ROM Exercises  Guidelines for moving clients o Assess the clients abilities and limitations o Medicate client to provide optimal pain relief o Organize environment and request needed help to ensure safety
 
o Explain what you are going to do and how you expect your client to help  General Principles of ROM Exercises o Permit client to do as much as his or her capabilities allow o Consider safety precautions o Follow the principles of body mechanics o Keep movements smooth and rhythmic o Prevent trauma (e.g. Friction against skin, pulling joints) o Check client for proper body alignment and comfort, and provide client with call bell before leaving AMBULATION o Dangling of the legs o Assisting the client with ambulation o Transfer belts o Mechanical aids o Muscle strengthening to facilitate ambulation ASSISTIVE DEVICE for WALKING  CANES o Types- single, tripod cane, quadripod cane o Patient must hold the cane in hand opposite affected extremity. Advance cane as the affected leg is moved forward  WALKER o Hip level o Lift and walk o Positioned at the back when going up the stairs o Positioned in front when going down stairs  CRUTCHES  Assure proper length o With patient standing: top of the crutch is 2 inches below the axilla and the tip of each crutch is 6 inches in front and to the side of the feet ( 2 inches forward, then 4 inches to the side) o Patients elbows should be slightly flexed when hand is on bar (30 degrees) o Weight must be borne by axillae, but on palms of the hand to prevent crutch palsy  CRUTCH GAIT o Four point gait. Advance right crutch followed by the left foot, then left crutch followed by right foot o Two point Gait- Advance right crutch and left foot together, then the left crutch and the right foot together o Three point Gait- Advance both crutches and the affected leg together, followed by the unaffected leg. None or little weight-bearing is allowed. o Swing to gait-Advance both crutches, swing the body so that the feet will be at the level of crutches o Swing through gait-Advance both crutches, swing the body so that the feet will be past the level of crutches  Going up and down the stairs o Up with the good (good leg first, then the bad leg and crutches) o Down with the bad ( bad leg and crutches first, then good leg) TRANSFERS  Two or three persons lift  Hydraulic lifts
 Stand-up assists lifts o Safety alert: The under-axilla lift techniques, where care providers pull the client by grasping the arms and under the axilla should never be employed. This technique exerts pressure on the brachial plexus that can affect the nerve function to the neck, shoulder, arms and hands. It can also subluxate the shoulder. Also this technique is the cause of poor body mechanics for the nurse and has been associated with L5-S1 back injuries. Transport of Clients Guidelines for Safe Lifting  Consider the weight of the patient together with the weight of the stretcher or other equipment being carried and determine if additional help is needed.  Know your physical ability and limitations. Know your combined ability with your partner. If absolutely necessary, you can ask bystanders to help. You or your partner must be in charge and give the orders, not the bystander.  Lift without twisting. Avoid any kind of swinging motion when lifting as well.  Position your feet shoulder width apart with one foot slightly in front of the other. Wear proper boots that go above the ankle to protect your feet and help keep a firm footing. Boots should have nonskid soles.  Communicate clearly and frequently with your partner. Decide ahead of time how you will move the patient and what verbal commands will be used. Also, tell the patient what you will be doing ahead of time. A startled patient may reach out or grab something and cause a loss of balance.  Position the stretcher at a right angle to the patient's bed with the head end of the stretcher at the foot of the bed.  Prepare the stretcher by unbuckling the straps, removing other items, and lowering the closest railing.  Both EMTs stand between the stretcher and the bed, facing the patient.  The EMT at the head end of the stretcher slides one arm under the patient's neck and shoulders, cupping the far shoulder with his or her hand and cradling the head.  The second EMT slides one arm under the small of the patient's back, slides the arm under the buttocks and lifts slightly to allow the first EMT to slide an arm under the waist.  The second EMT reaches under the patient's lower legs.  The patient is pulled to the edge of the bed, then lifted and curled toward the EMT's chest.  The EMTs rotate to be in line with the stretcher, then place the patient gently on to it. Draw Sheet Method  Loosen the bottom sheet on patient's bed.  Adjust stretcher to height of bed, unbuckle straps, lower both rails, and remove all items from stretcher.  Place the stretcher against the side of the bed.  Both EMTs reach across the stretcher and grasp the sheet firmly beside the patient's head, chest, hips and knees.  Slide the patient gently across and onto the stretcher. If enough personnel are available, the patient may be lifted by grasping the sheet on both sides of the patient at the chest and hip simultaneously. Nursing Intervention to Promote Activity and Exercise  ADL  Exercises  Purposes  it aims to achieve the maximum body function for each particular individual.  TYPES o AROM  Performed for the client without assistance form other individuals or mechanical means. It maintains the strength of muscles
PROM  perform for the client at a time the client cannot do them. Active-Resistive ROM Active-Assistive ROM  performed the client exercises self-assisted or with assistance from another person or a mechanical means o Isotonic  the muscle contracts, it is used to promote muscle length (e.g  lifting) o Isometric  are exercise in which the client exerts force without changing the length of the muscles. It helps in maintaining muscle tone. Example o Gluteal muscle setting  this is done by contracting and relaxing the buttocks o Quadriceps setting exercise  this is performed by pressing the popliteal space against the mattress.
