Three Domains of learning (B. Bloom)
-Cognitive domain: involves knowledge & the development of intellectual skills. This includes the recall or recognition of specific facts
-Affective domain: includes the manner in which we deal with things emotionally, such as feelings, values, appreciation, enthusiasms, motivation, & attitudes.
-Psychomotor domain: includes physical movement, coordination, & use of the motor-skill areas.
4 physical changes that effect learning in the older adult pt
-Sensory: vision, hearing, touch, and smell
-Motor control: decreased muscle strength, loss of flexibility, & endurance
-Nervous System: reduced speed of nerve control, conduction, confusion, slow response and reaction time
-Memory Loss: slow recall or poor short-term memory
-Nursing Interventions:
-Set achievable goals
-Use visual aids in large print
-Increase teaching time
-Allow for rest periods
-Repeat information
-Use prior experience, examples the pt can relate to
-Teach in a quiet environment, comfortable to the pt
Complications of positioning
-Undue pressure on a body part should not obstruct vascular supply (postural hypertension, venous pooling, compartment syndrome)
-Respiratoin should not be impeded by pressure of arms on chest (dyspnea)
-Nerves must be protected from undue pressure, improper positioning can cause serious injury or paralysis (injury of brachial, ulnar, radial, sciatic, tibial, or peroneal nerves)
-Integumentary breakdown of the skin and scalp (alopecia)
-Reproductive (genital injury)
-Sensory effects (corneal abrasion, conjunctival edema, ear injury)
-Skeletal (aseptic necorsis of femoral head, fx of symphysis pubis)
-Muscular pain in lumbar, neck, and shoulders
-Precautions for pt safety for thin/elderly, obese and pts with deformities or handicaps
Surgical Asepsis
Absence of microorganisms in the surgical environment to reduce th risk for infection
Intra-operative heat loss and hypothermia
During anesthesia, pt's temp may drop:
-Reduced glucose metabolism may cause metabolic acidosis
-Core temp: < 98.0
Caused by:
*low OR temp
*infusion of cold fluids
*inhalation of cold gases
*open wounds or body cavaties
*decreased muscle activity
*advanced age
*pharmaceutical agents
Signs and symptoms of malignant hypothermia
-Inherited muscle disorder chemically induced by anesthetic agents
-Ventricular dysrhythmia
-Decreased cardiac output
-Oliguria (decreased urine volume)
-Abnormal transport of calcium causes:
*tetanus like movements (often in jaw)
-Late sign: rapid increase in temperature
Precautions taken by OR team to prevent medical-legal problems
-Check patient's ID band
-Have state and spell full name and date-of-birth
-Ask pt to list any allergies
-Mark the site on the patient
-All instruments to be used during the surgery are counted and documented on the white board before the surgery and again at the end of the surgery
Regional Anesthesia
-The temporary interruption of the transmission of nerve impulses to and from a specific area or region of the body
-Nerve block
-An injectin into the the epidural space inside the spinal column (not in the dura mater)
-Will have a higher dosage than spinal because doesn't make direct contact with spinal cord or nerve roots
-aka subarachnoid block
-lumbar puncture between L4 or L5 or S1
-Injected into subarachnoid space
-aka transsacral
-produces anesthesia of the perineum and occasionally the lower abdomen
Nerve Block
-A technique in which the anesthetic agent is injected into and around a nerve or small group of nerves
Advantages of using spinal or epidural rather than general anesthesia
-Patient awake with spinal/epidural
-Minimal effect on respiratory and CV systems
-Decreased recovery time
-Prolonged analgesic effect post-op
Reasons for using epinephrine with local anesthetics
-It contricts blood vessels, which prevents rapid absorption of anesthetic
-Prolongs local action
-Prevents seizures
Conscious Sedation
Will fill in later
Post-op Urine output
-Anesthetics, anticholinergic agents and opiods interfere with perception of bladder fullness and inhibit the ability to void within the 8 hours of surgery
Progressive Diet
will fill in later
-Ex: prednisone
-Interaction: Cardiovascular collapse can occur if d/c'd suddenly
-A bolus may be given before and right after surgery
-Ex: hydroDIURIL
-Interaction: may cause respiratory depression resulting from an electrolyte imbalance
-Ex: Thorazine
-Interaction: may increase hypotension action of anesthetics
-Ex: Diazepam (valium)
-Interaction: may cause anxiety, tension, and seizures if withdrawn suddenly
-Ex: erythromycin
-Interaction: When combined with a curariform muscle relaxant, nerve transmission is interupted and apnea from respiratory paralysis may result
-Ex: phenttoin (dilantin)
-Interaction: may need to be administered IV to keep pt from having seizure during surgery
Monoamine Oxidase (MAO) inhibitor
May increase the hypotensive action of anesthetics
Informed Consent
Voluntary and written:
-must be freely given, without coercion
-Should contain explanation of surgery, description of benefits and alternatives, an offer to answer questoins , Instructions that inform pt that they may withdraw consent, a statement informing pt if the protocol differs from customary procedure
-Important: protects the pt from unsanctioned surgery and protects the surgeon from claims of of an unauthorized operation
Suffixes used
-ectomy: removal of
-lysis: destruction of
-orrhaphy: repair or suture of
-oscopy: looking into
-ostomy: creation of opening into
-plasty: repair or reconstruction
Wound healing: Primary
-Wound is clean in a straight line, with little loss of tissue
-All wound edges are well approximated with sutures
-Usually rapid healing with minimal scarring
Wound Healing: secondary
-Large wound with considerable tissue loss
-Natural healing by formation of granulation tissue
-Healing takes longer and results in more scarring
Wound Healing: Tertiary
-Time delay before wound is sutured
-Greater granulation, risk of infection, inflammatory reaction than primary intention
-Late suturing and more scaring
Factors affcting Wound Healing
-Good handwashing
-Diet: vit C and protein
-Adequate hydration
-Splint incision when CDB
-Type and location
-Pt age
-Other medical Dx
-Lifestyle factors
Phases of wound healing
*1-7 days
*WBC, clot formation, cell migration
*7-30 days
*new tissue, granulation, diet important
*21 days to several months (even years)
*tissue strengthens, scar is reduced
Terms R/T Wound Healing
-Granulation: migration of fibroblasts with secretion of collagen and new capillary formation (wound is fragile and bleeds easily)
-Eschar: thick necrotic tissue (may be white, black, or gray)
-Debridement: removal of non-viable tissue (may be done surgically or mechanically)
Problems Interfering with Wound Healing
-Dehiscence: partial or complete seperation of wound edges
-Evisceration: dehiscence with abdominal contents protruding from wound
-Infection: characterized by increased temp of surronding tissues, swelling, redness, purulent drainage; Dx with wound culture, increased WBC
Deep Vein Thrombosis
-Risk factors: dehydration, decreased cardiac output, venous pooling, bedrest, and hypercoagulability, history of oral contraceptives
-S/S: + homan's test, edema, increased temp & HR, chills, redness, cramps
-Prevention: leg exercises, AE or pneumatic hose, early ambulation, adequate hydration
