Q

What are the 7 principles of surgical asepsis?

A
  1. Sterile remain sterile when touched by sterile
  2. Sterile objects can be placed on sterile field- sterile objects kept in clean/dry areas, sterile packages must remain dry and intact
  3. Sterile object/field out of range of vain and object held below someone’s waist is contaminated (keep field in view at all times and don’t turn back)
  4. Sterile object/field becomes contaminated by long exposure to air (decrease talking, sneeze, laugh, cough, hold items close to sterile field)
  5. When sterile surface contacts with wet contaminated surface, sterile object and field is contaminated by capillary action (make sure surface below sterile field is dry, avoid apply when pouring, moisture seeping though sterile package=microorganisms travel to sterile object)
  6. Fluids flows in direction of gravity (keep instruments lower than handles, hands above elbows-surgical scrub)
  7. Edges of sterile field are contaminated (2.5 cm border)

Q

What is an acute wound?

A

Q

What are the 4 stages in wound healing?

A
  1. Hemostasis- within minutes of injury body send platelets to site to aggregate/vasoconstrcit blood vessels, starts clotting
  2. Inflammatory- body protective response to injury, last 2-4 days, histamine released causes vasodilation and WBC migrate, leukocytes ingest bacteria and dead cells
  3. Proliferative- last 3-24 days, new blood vessel forms, collagen contracts and decreased wound bed size to speed healing, epidermal cells migrate over granulation tissue
  4. Maturation/remodel- up to 2 yrs, surface of wound look healed , collagen production continues, scar formed

A

Age (young and old), nutrition, obesity, immune competence (risk for infection), fluid and electrolytes imbalance (shifts during surgery).

44
Q

Day of surgery?

A

Hygiene (patient shower before, no makeup/nail polish), removes prostheses and dentures, void before surgery/laxatives sometimes, vital signs, document, allergies, eliminate wrong site/surgery (double check process).

45
Q

What’s informed consent?

A

Explain precedence/risk and benefits/ outcomes/ recovery process/alternatives. Usually doctor does this but nurse can answer questions and be the in between person.

46
Q

General anesthesia, regional, and local?

A

General- loss of sensation, reflex, consciousness overall
Regional- loose sensation to large area of body
Local- loose sensation to small area of body like tooth filling

47
Q

What’s procedural sedation?

A

Depressed level of consciousness. Reflexes not loss like wisdom teeth removal.

48
Q

More about regional anesthesia and what if affects?

A

Affects sympathetic nerves (fight or flight) which results in vasodilation. Affects sensory nerves (decreased sensation with pain and temperature changes), and motor nerves ( e.g. can’t make legs).

49
Q

What to do post-operative procedure?

A

Given a report. Assess ABCs (airway, breathing, circulation). Assess mental status, incision site, temperature, IV fluids, pain. Priorities are ABCs, prevent wound infection, manage pain.

50
Q

What is dermatone?

A

Area of skin supplied by a spinal nerve. Use ice to assess patients skin and see if they feel its temperature. We want decreased sensation of ice in surgical area.

51
Q

What is PCA?

A

Patient controlled analgesia. Self administration of opioid analgesic. Push button to release opioid by IV. Monitored by RN and assess for comfort level, O2, RR, sedation level. Side effects are respiratory depression and naloxone used to combat adverse effects.

52
Q

What is epidural analgesia?

A

Inject anise this into epidural space. Assess for HR, RR, BP, sedation and comfort level, O2 stats, sensory level, motor function, and the epidural site.

53
Q

What is complete and incomplete fracture?

A

Complete- break through entire bone width
Incomplete- break through part of bone

54
Q

Bone healing phases?

A
  1. Hematoma- semisolid clot form 24-72 hrs
  2. Converted into Granulation tissue (fibrocartilage) 3-14 days
  3. Callus formation causes minerals to be deposited within 6 weeks
  4. Osteoblastic proliferation is callus reabsorbed, transform to bone, start 4-6 weeks and can take up to 1 yr
  5. Bone remodel- pre injury shape and strength starts at 4-6 weeks and can take up to 1 yr
55
Q

What is pathologic/fragility fracture, fatigue/stress fracture, and compression fracture?

A
  1. Occur during normal activity or following minimal injury when bone is weakened by disease process
  2. Normal bone subjected to repeated stress without bone/muscle recovery
  3. Force applied to long axis of cancellous bone
56
Q

What are complications of fractures?

A

Venous thromoembolism (VTE)-blood clot forms in vein, S+S (edema, warmth, tender), prevent by anti-embolism socks, mobility, dx by doppler ultrasound

Infection- S+S (tenderness, pain, redness, swell, purulent drainage, warmth, delayed or no union of surgical site)

Acute compartment syndrome- increase tissue pressure in limited space cause decreased perfusion, S+S (pain, pallor, paralysis, pulseness), prevent by ice/elevate, treatment remove ice

Fat embolism syndrome (FES)- fat globules released from bone marrow to bloodstream 12-48 hrs after surgery=reduced perfusion, S+S (agitation, vision change, headache. LOC)

57
Q

What is etiology, incidence, and health promotion of fractures?

A

E- trauma, sports, malnutrition, bone disease
I- rib, femur, wrist fractures
HP- health teaching on risks for musculoskeletal injury

58
Q

Neurovasuclar assessment?

A

CMS (circulation-colour, temp., cap refill, pulse, movement, sensation-pain)

59
Q

Physical assessment for fractures?

A

Edema, pain, muscle spasm, deformity, ecchymosis, loss of function, crepitation.

60
Q

Non-surgical management of fracture?

A

Closed reduction (manual realignment of bone fragments to previous position), splints/boots/casts (immobilization), traction (apply pulling forces to injured part of body while counter traction pulls in opposite direction).

61
Q

Cast care?

A

Post cast elevate limb, apply ice, avoid handling, neurovascular check (CMS), and don’t get wet.

62
Q

What are intracapsular and extra capsular hip fractures?

A

I- femoral neck fractures, inside joint capsule, usually r/t bone disease, treat with insertion of femoral head prethesitc
E- outside of joint capsule, usually r/t fall or trauma, treat with screws/pins

63
