    include family--Occurs in home, surgeon's office, preadmission unit . Printed literature, videos might help. Relieves anxiety, increases pt satisfaction, speeds recovery, and decreases perceived pain. What factors are influenced :
    1) Ventilatory function: improves ability and willingness to deep breath.

    2) Physical functional capacity: understanding and willingness to ambulate

    3) Sense of well-being: less anxiety and greater sense of psychological well being.

    4) Length of hospital stay: reduces by preventing or minimizing post op complications.

    5) Anxiety about pain and amt of pain med needed: less anxious, ask for what they need, use less meds
  46. Timing
    Preoperative teaching is best taught a week before admission, and when pt is less anxious, assess readiness to learn-environment!

  49. What is informed consent?
    anyone over 18 will sign a form before a procedure. They must be of sound mind and mentally competent, not under meds that alters mental state, no confusion, not unconscious - usually done by surgeon and anesthesia team, but nurse can notify team/surgeon if they suspect pt is impaired

  50. Who can witness the signing of this consent form?
    Office Nurse or family member. As a student you can NEVER witness anything!
  51. WHY is postoperative routines important?
    Pt understanding means they are lsee likely to worry when the nurses perform these assessments, It is important to neither overprepare nor underprepare the pt and family.
  52. Why is Sensory Preparation important?
    EX: or room very bright, machines will hum, will apply a cuff, the cuff tightens

    Informing the pt about these and other sensations in the OR will reduce anxiety before the pt is anesthetized, which will help decrease the amt of anesthetic needed for induction.

    The ambulatory surgical pt will most likely be discharged home. The non amb pt goes to med-surg floor based on the following guidelines- Talk, Walk, Drink, Urinate, - discharged to med-surg by surgeon
  69. In Post-anesthesia care for ambulatory surgery there are 2 phases. Describe them
    Phase 1: same as hospitalized

    Phase 2: Prepares pt for discharge and self care.
  70. What should client discharge teaching include when the client/family are ready for discharge?
    dressing and wound care, activity restrictions, possible dietary restrictions, warning signs of complications, review of prescribed meds
  71. Assessment:

    Respiration: assess the quality of the pt respirations and the patency of the airway. What should you watch for?
    slow, shallow breathing

    respiratory rate, rhythm, depth and quality of ventilatory movement.

    Auscultate the lungs for adventitious sounds
  72. Assessment:

    Circulation, what do you need to monitor? Look for?
    • Review baseline
    • pulse rate, rhythm ,
    • BP
    • Continuous ECG if ordered
    • level of consciousness
    • skin, nail beds, mucous membranes, bleeding

    Watch for hemorrhaging, eectrolyte imbalances, depression of normal circulatory regulating mechanisms.

    Temperature control what might you notice?
    When patients wake up they ofte feel cold. Shivering is not always a sign of hypothermia but rather a side effect of anesthetic agents.

    monitoring temp. also aids in early detection of infection

    WHAT you looking for? What should you do?
    Monitor and accurately record intake and output to assess fluid balance as well as renal and cardiac function. Measure all sources of input and output and consult with the HCP if necessary.

    Skin integrity and condition of the wound:
    what you doing? what you going to look for?
    • Thoroughly assess pt skin.
    • Rash may be drug sensitivity or allergy, abrasions or petechiae from inadequate padding during positioning.
  76. If a wound becomes infected what do you need to know?
    • It usually occurs 3 to 6 days after surgery
    • Ongoing observation of the wound includes inspection for redness, warmth, edema , and purulent drainage.
    • Tell care giver or family to immediately report any signs or symptoms of an infection to the surgeon

    What do I need to know? Look for?
    • 1)anesthetic agents slow gi motility and cause nausea
    • 2)manipulation of the intestines during abd surgery further impairs peristalsis.
    • 3)Normal bowel sounds usually return in 24 hr.
    • 4)Paralytic ileus, loss of function of the intestine that causes abdominal distention is always a possibility after abd surgery.
  78. hemothorax
    Hemothorax is a collection of blood and fluid between the parietal and visceral pleurae.
  79. some of the health conditions that can cause respiratory acidosis
    Respiratory Acidosis Causes are Hypoventilation, atelectasis, pneumonia, respiratory failure, airway obstruction, head injuries

    Caused by High Anion Gap, Diabetic ketoacidosis, renal failure, lactic acidosis from exercise, diarrhea,
  82. metabolic alkalosis causes
    Excessive vomiting, prolonged gastric suctioning, Hypokalemia, Hypercalcemia, use of drugs- sodium bicarbonate and diuretics, excessive Aldosterone
  83. PCA Pump
    provides pt with control over pain, explain how to operate, make sure they can operate it, importance of administering it as soon as pain is persistent b/c it takes time to act, and that there is no harm- mechanisms to make it controlled and safe- overdose and dependence
    Critical thinking is important in post op care. Consider the interrelationship of all body systems and the effect of therapies.
  85. Implementation:
    One of the greatest concerns following surgery is what?
    1) airway obstruction resulting from weakness of pharyngeal or laryngeal muscle tone

    2) aspiration of emesis

    3) accumulation of secretions in pharynx, trachea, or bronchial tree

    4) laryngeal or subglottic edema
  86. How would you maintain airway patency?
    • 1) Position the patient on one side with the face downward and the neck slightly extends.
    • 2) suction the artificial airway and oral cavity
    • 3) begin deep breathing and coughing exercises
    • 4)administer oxygen as ordered and monitor oxygen sat.
  87. Preventing deep vein thrombosis curing convalescence;
    what interventions should be implemented asap
    • 1) Encourage pt to perform leg exercises at least every our while awake unless contraindicated.
    • 2) Apply elastic antiembolism stockings
    • 3) Encourage early ambulation but before assess vital signs.
    • 4)Avoid positioning pt in manner interrupting blood flow.
