Exam 1 Flashcards
Three phases of inflammation
First: vascular and cellular
Second: exudate production
Third: reparative
Focused health history- inflammation
Possible irritants: physical (trauma, heat/cold, radiation), chemical (acid, alkalis, poisons, gases), microorganisms (bacteria, fungi, parasites, viruses)
Five signs of inflammation
- Erythema
- Edema
- Heat
- Pain
- Loss of Function
Diagnostic tests- inflammation
- Erythrocyte Sedimentation Rate (ESR/SED): 0-20
2. C-Reactive Protein (CRP): <1 mg/dL or <10 mg/L; measures response to antibiotic/antiinflammmatory meds.
NSAID’s
inhibit the COX enzyme; reduce swelling, pain, and stiffness in joints
COX-1 Inhibitors (1st gen)
Loss of stomach lining, prevents blood clots, decreases fever,
COX-2 Inhibitors (2nd gen)
Reduces pain and inflammation, Do not disturb stomach lining
Ibuprofen (Motrin/Advil)
COX-1 inhibitor; produces analgesic, anti-inflammatory, reduces fever SE: N&V, dyspepsia, dizziness, rash, heartburn
Celecoxib (Celebrex)
COX-2 inhibitor; reduces pain and inflammation, used for osteoarthritis and rheumatoid arthritis SE: diarrhea, dyspepsia, headache, URTI, GI discomfort, abdominal pain, peripheral edema (Do not use in pt with existing cardiac issues
Ketorolac (Toradol)
NSAID; intraocular anti-inflammatory; inhibits prostaglandin synthesis, reduces prostaglandin levels in aqueous humor, reduces pain SE: headache, nausea, abdominal cramps, dyspepsia
Corticosteroids
Controls inflammation by suppressing components of the inflammatory process at site of injury; also used to prevent transplant rejection; administered once a day in large dose
Prednisone (Deltasone)
prevents/suppresses immune reactions and decreases tissue response in inflammatory process SE: hyperglycemia, masks infection signals, edema, weight gain, thin skin, bruising, heartburn, diaphoresis, mood swings, delayed wound healing
Perioperative Nursing Practice
Encompasses care in all phases
Preoperative Focused Assessment: Older Adults
increased risk for complications, Anesthesia may increase confusion or dementia, skin assessment, breath sounds, coughing
Preoperative Focussed Assessment: Children
Maintaining temperature 97-100, talk at their level, involve parents, use correct terms they understand, role play, scary stuff last
Preoperative Focussed Assessment: Drugs/Substance abuse
pulmonary complications increased in smokers, alcohol and drugs alter response to anesthesia and pain meds, Antihypertensive, Tricyclic antidepressants, NSAIDS increase risk of complications
Preoperative Focused Assessment: History
decreased immunity, diabetes, pulmonary disease, cardiac disease, hemodynamic instability, multi-systm disease, coagulation defect, anemia, dehydration, infection, hypertension, hypotension. Family history: malignant hyperthermia, cancer, bleeding disorder
Cardiopulmonary Preoperative Assessment
V/S, Report: Hypo/hypertension, HR < 60 or >120, irregular heart beat, chest pain, ShOB, dyspnea, tachypnea, SpO2 <94%
Preoperative Nutritional Assessment
assess for malnutrition, need vitamins and protein before and after procedure
Preoperative Patient Medication Review
NSAIS’s, Aspirin, and Anticoagulants may be stopped 7-10 days prior to surgery, pt may be started on a a heparin drip to prevent bleeding during surgery.
Preoperative Physical Assessment
Head to toe including ROM, LOC, skin integrity; provides baseline for after surgery
Pre-surgical Screening Tests
- Chest Xray: preexisting cardiac/pulmonary issues
- EKG: establishes baseline for new or existing cardiac issues
- CBC: Indicates need for blood transfusion, fix any current blood issues before surgery
- Electrolyte level: indicate need for electrolyte replacement during/prior to surgery
- UA: indicate current drug levels, urine concentration
Preoperative Medications
- given in holding area
- give any ordered meds
- facilitates admin of anesthesia or reduces risks of it
- insulin may not be given prior to surgery; anticoags d/c 5-7 days prior to surgery
- antianxiety, antiemetic, antibiotics may be given prophylactically
Nursing Diagnosis PreOp
Deficient knowledge related to unfamiliarity with surgical procedures
Anxiety related to new or unknown experiences
Planning/Outcomes PreOp
- Pt must be informed and know what to expect during surgery
- Pt has manageable anxiety prior to surgery
Caring Interventions PreOp
DO NOT OVERWHELM
- focus on teaching
- explore their level of knowledge and understanding
- provide info on informed consent, dietary restrictions (NPO), preps before surgery, exercises after surgery, plans for pain management
- teach limitations, eating, working after surgery
Day of Surgery
- Client teaching complete
- Informed consent signed
- Adhered to NPO restriction
- In surgical gown
- ID bands are on
- No jewelry, dentures, contact lenses, nail polish
- voiding prior to transfer
- Preop meds are given
- V/S taken
- Preop lab work complete
- Skin has been prepped
- Pt history reviewed
Surgical Classifications: urgent
Surgery needs to be done in 24-48 hours
Surgical Classifications: emergency
Surgery needs to be done immediately
DOR: Major
Prodecure or greater risk, longer and more extensive
DOR: Minor
Procedure w/o significant risk, often done without local anesthesia
DOR: Diagnostic
Performed to determine the origin and cause of disorder or cell type for cancer
DOR: Curative
Performed to resolve a health problem by repairing or removing the cause
DOR: Restorative
Performed to improve a pt functional ability
DOR: Palliative
Performed to relieve symptoms of a disease process; does not cure
DOR: Cosmetic
Performed to alter or enhance personal appearance
Informed Consent
- Valid for 30 days after signing
- Signed prior to any sedation
- Voluntary and informed (Physician job to explain surgery, risks, alternative therapies, outcome)
- Protects pt, surgeon, hospital, and employees
- Four conditions: Adequate disclosure, sufficient comprehension, voluntary, competent
- RN clarifies what surgeon has already said
Circulating Nurse
Coordinates, oversees, and involved in pt nursing care in the OR. set up the OR, positions pt with pads, safety straps, warming blankets, provides comfort and reassurance, tests equipment, protect pt privacy, monitor traffic in OR, maintain sterile field in OR, communicates to family members, documents care, drains, count of all materials, communicates with PACU
Scrub Nurse
Sets up sterile table, drapes pt, hands sterile supplies and equipment, counts sponges, sharps, and instruments
Time Out
Surgical Team ensures: Pt name, DOB, surgical consent form, kind of surgery, location, side, correct position of pt, drug allergies, antibiotics given
General Anesthesia
Reversible loss of consciousness induced by inhibiting CNS, causes analgesia and amnesia, loss of muscle tone/reflexes, no sensory perception to consciousness, increased risk of cardiac/pulmonary problems
General Anesthesia: Inhalation
Most controllable method, pulmonary ventilation reversal, used in combination with other agents for prolonged procedures, limited muscle relaxant, posted nausea and shivering common
Nitrous Oxide
General inhaled anesthetic, Anxiolytic, analgesic, euphoric; rapid acting, rapid reversal, non depressant, nontoxic inhalation analgesic to supplement other anesthetics; SE: blurred vision, confusion, drowsiness, faintness, lightheaded, sweating, weakness
Isoflurane (Forane)
nonflammable liquid administered by a vaporizer. general inhaled anesthetic; SE: shivering, nausea, vomiting, ileum
General Anesthesia: IV
rapid and pleasant induction, low incidence of posts N/V, must be metabolized and excreted from body for reversal, contraindicated in liver or kidney disease, increased cardiac and respiratory depression
Propofol (Diprivan)
rapid acting general anesthetic/sedative hypnotic; inhibits sympathetic vasoconstrictor nerve activity, decreases vascular resistance, produces hypnosis rapidly; SE: involuntary muscle movements, apnea, hypotension, N/V, cardio depression, delirium, euphoria, resp. depression
