    • Educator
    • an advocate 
    • and a promoter of health
  2. Perioperative nursing places special emphasis on?
    • Safety
    • advocacy
    • and patient education
  3. When does the preoperative period begin and end?
    The preoperative period begins when the patient is scheduled for a surgical procedure and ends when the patient is transfered to the OR (operating room)
  4. When does the intraoperative period begin and end?
    The intraoperative period begins when patient enters the surgical suite and end at the time of transfer to the postanesthesia recovery area, same day surgery (SDS), or intensive care unit (ICU)
  5. When does the postoperative period begin and end?
    Postoperative starts at the completion of surgery and transfer of patient to postanesthesia care unit (PACU), same day surgery (SDS), or intensive care unit (ICU)
  6. Determine the diferent reasons/purposes for surgery?
    • Diagnostic = determine the origin and cause of a disorder
    • ( Breast biopsy, exploratory laparotomy or Athroscopy)
    • Curative = resolves  a health problem be removing or repairing the cause.
    • (Appendectomy or hysterectomy)
    • Pallitive = Relieves symptoms but does not cure it
    • (colostomy, nerve root resection, tumor debulking)
    • Restorative = Improves functional ability
    • (total knee replacement, finger reimplantation)
    • Cosmetic = enhances personal appearnce
    • (Liposuction, breast implants, scar removal or rhinoplasty)
  7. Determine the different type of surgery?
    • Elective = Planned and nonacute type of surgery
    • (cataract removal, hernia repair, total joint replacement or hemorrhiodectomy)
    • Urgent = Life threatening if not done within 24-48hr
    • (Bladder or intestinal obstruction, kidney stones, bone fractures, eye injury or acute cholecystitis)
    • Emergent = immediate intervention due to life threatening issues.
    • (gun shot or stab wound, compound fracture, severe bleeding, AAA, or apendectomy which is also curative)
  8. Determine the different degree of risk or extent of surgery?
    Surgery can be Minor with out significant risk with the use of local anesthetic. Surgery can also be Major with greater risk and longer and more extensive.

    • Extent of surgery can either be Simple such as simple/partial mastectomy (only the involved area)
    • Radical surgery beyond the obviously involved area such as a complete radical mastectomy or hysterectomy.
    • MIS- minimally invasive surgery is performed in a body cavity or area through an endoscope.
  9. How does alcohol, drug and substance abuse affect a patients response to surgery?

  17. What would be the nursing intervention for the aging patient with reduced ability to excrete waste products or a decline in glomerular filtration rate?
    • Assess overall hydration
    • Monitor electrolyte status
    • Rational; (Ongoing assessment helps detect fluid and electrolyte imbalances and decreased renal function)
  18. What would be the nursing intervention for an aging patient with decreased blood flow to kidneys or Nocturia common?
    • Monitor intake and output
    • Rational; (Ongoing assessment helps detect fluid and electrolyts imbalances and decreased renal function.)
    • Assist frequently with toileting needs, especially at night Rational:( frequent toileting helps reduce incontinence and falls.)

  38. What are appropiate identifiers when providing instruction, administering drugs, marking surgical sites and performing any procedure?
    Patient name and MRN should be checked at all time before any administration of drugs or nay procedure is preformed. Blood donation gives a special tag to the patient and the donated bag.

    Time Out has been adopted to allow for safety of the patient to be acknowledged; patient identity, correct side and site, correct patient position, agreement on procedure and availability of correct implants must be verified by all team members
