Q

how would the following diagnostics be affected by hypovolemia

BUN
hct
K,
Na

A
  • BUN can be elevated because of dehydration or decreased renal perfusion and function.
  • Inc Hct.
  • K and Na levels may be reduced or elevated.
  • Hypokalmeia occurs with GI and renal losses
  • Hyperkalmeia- adrenal insufficiency
  • Hyponatremia –inc thirst and ADH release
  • Hypernatremia – inc insensible losses and diabetes insipidus
  • Urine specific gravity is inc in relation to the kidneys attempt to conserve water

Q

what is azotemia

A

• Azotemia (increased nitrogen levels in the blood) can occur when urea and creatinine are not excreted due to decreased perfusion by the kidneys and decreased excretion of wastes. High uric acid levels (hyperuricemia) can also occur from increased reabsorption and decreased excretion of uric acid by the kidneys.

Q

should pt mobilize or rest often if edematous

A

• Regular bed rest may be beneficial because bed rest favoursdiuresis of edema fluid.because of diminished venous pooling and increase in circulating blood volume.

Q

what assessments should you do for resp system

A
  1. RR, look in their mouth, listen to resp sounds (may sound like gargling), may need to put hand in front of nose to feel breath
  2. look in their mouth, RR etc
  3. for swelling, ask pt how their throat feels

look for laryngeal edema

Q

how are most anesthetics and how does this affect nursing care

A
  1. Sometimes people after anesthetics will have lg pauses between inhalation/exhalation. Look at 02 sats, LOC (older adults and kids can be hyperactive or agitated), RR, listen to lung sounds, most anesthetics are excreted by the body by breathing (ask the pt to take deep breaths while listening)
  2. DB&C and incentive spirometry.

Q

why does pt have risk for DVT after sx

A

Risk for DVT, embolus d/t immobility for extended period during surgery, increased clotting response d/t surgical process, reduction in anticoagulant medications in preparation for surgery.
During sx we may have very thick blood, stress causes inc in clotting factors, venous stasis

Q

why is postop pt at risk of dysrhythmia

A

secondary to electrolyte imbalance, acidosis, pain, anesthetic agents, hypothermia, stress

23
Q

other than pain what postop assessments should be done r/t discomfort (3)

A

Assessment for nausea and vomiting-similar to LOTARP. Put on in and outs
Pruritus
People are cold when they return from OR, take temp and give blanket

24
Q

if the pt hasnt voided _hrs post sx use a bladder sanner to check urine amount

A

If they havent voided in 2hrs post sx check with bladder scanner

25
Q

rationale for these statements
“The post-operative patient will most likely have an isotonic solution hanging during the post-operative period.”
“Hypotonic and hypertonic solutions are rarely used in the surgical context.”

A

?

26
Q

WHAT IS PACU.

what are the phases

A

Postanethesia care: is in the postanesthesia care unit (PACU) or recovery room or postanesthesia recovery room
Phases of Post anesthesia Care:
Phase 1 PACU: used during the immediate recovery place. Intensive care is provided
Phase 2: patient is prepared for self-care or care in the hospital or an extended care setting
Phase 3:prepared for discharge. Pt might sit in a recliners overa stretcher, to prepare for discharge

27
Q

how often are vitals done in PACU and when do you report changes in BP

A

• Vitals and general physical status q15 min. downtrend of less than 5mmHg systolic or

28
Q

hypopharyngeal obstruction and its treatment

A

• relaxation from anesthesia can extend to the pharynx so when the patient lies on back, the lower jaw and tongue fall backward and air becomes obstructed: hypopharyngeal obstruction. (treatment: tilting the head back and pushing forward on the angle of the lower jaw)

29
Q

how should bed be positoned for postop pt and their breathing

A

HOB at 15-30

30
Q

risk factors for N and V

A

• Risk factors for PONV: general anesthesia, female gender, nonsmoker, hx of nausea and vomitting, and hx of motion sickness

31
Q

what happens if you hear report that pt is feeling very nauseaous (what should you do)

A

With first report, pt turned to one side to promote drainage and reduce risk of asphyxiation.
maybe give PRN antiemetic

32
Q

gerontological considerations postop

A
  • Moved from stretcher slowly, BP & ventilation monitored
  • More susceptible to hypothermia
  • Change position freq: stimulate resps, promote circ & comfort
  • Prolonged recovery from sedatives d/t liver/kidney fx
  • Pre-existing health conditions necessitates more cardio, resp + renal supports
  • Less physiological reserve so need more frequent monitoring
  • Confusion + delirium post-op in 51% of older adults
  • Acute confusion d/t: pain, analgesic agents, hypotension, fever, hypoglycemia, fluid loss, fecal impaction, urinary retention, anemia
  • Restlessness possible from electrolyte imbalance, hypoxia, blood loss

its very important that they mobilize early to prevent resp complications

33
Q

pt teaching if being discharged direct after sx

A
  • Pt + family taught about expected outcomes and anticipated changes
  • Prescriptions given
  • Written instruction given
  • Provide appropriate telephone #’s
  • Info to provide includes: name of procedure, any permanent changes in anatomical structure, describe ongoing therapeutic regimen (including diet, activities to perform and avoid), date and time of follow up appointments, community resources &referals, pertinent health promotion activities…
  • Typically told 24-48hr window in which to limit activity (no alcohol, small meals, don’t make any important decisions…)
34
Q

when postop pt returns to floor how often do you do vitals

A

Vitals q15 for first hour and q30 min for next 2 hours..temp is monitored 4 hours for the first 24 hours.

35
Q

after first 24hrs postop how does nursing care shift

A

• Shift is quick from intense physiological management, symptomatic relief of adverse effects of analgesia to regaining independence and prep for discharge

36
Q

how to prevent resp complications

A
  • Crackles = sign of static pulm secretions = need for deep breathing + coughing, IS, freq position changes at least q1hr…prevents pneumonia + atelactasis
  • Splinting helps to reduce pt fear during coughing
  • Pain meds given to facilitate more effective coughing
37
Q

2 types of hypoxemia

risks for getting it

A

• 2 kinds of possible hypoxemia: subacute + episodic
o Subacute = constant low O2 sat but breathing appears norma
o Episodic = sudden, pt at risk for cerebral dysfx, myocardial ischemia, cardiac arrest
o Risks for this: sx (esp abdominal), obesity, existing pulmonary problems

38
Q

are eipidurals commonly used in chest sx

A

•• Epidural infusions are used with caution in chest procedures because may ascend into spinal cord and affect respiration

39
Q

how can pain contribute to pulmonary embolus

A

• Pain activates stress response: adversely affects cardiac and IR; vasoconstriction and muscle tension resulting from pain inc O2 demands; also inc platelet aggregation + blood viscosity = inc risk for PE

40
Q

wat could you teach pt about mobility that would encourage them to mobilize

what should you teach if cant stand up

how else can you physically assist them to mobilize

A
  • Less pain + shorter stay if ambulating
  • Remind pt that early ambulation = prevention of complications
  • Mobility stimulates peristalsis – limits GI distension

• Help patient get sit up in bed with head of bed elevated and encourage to splint if needed, position upright and swing legs over, help patient stand beside the bed
-encourage them to do self care

• If cant stand up, bed exercises are encouraged

41
Q

what do if pt has v low body temp

A

report to dr

tx may include, 02, hydrate, nutrition. monitor for dysrhythmias

give blankets

42
Q

how much mobility does pt need in order to be d/c

A

must be able to toilet self, get in and out of bed, walk certain distance

43
Q

instructions DB and C

A

abdominal (diaphragmatic) and pursed lip breathing
o semi-sitting in bed or chair or,.klying in bed w one pillow
o flex knees to relax muscles of the abdomen
o place 1 or 2 hands on abdomen just below ribs breathe in deep through nose, keep mouth closed
o concentrate ion feeling abd rise as far as possible. don’t arch back, relax. don’t use chest and shoulder muscles
o if difficult to raise abd take quick forceful breath\
o purse lips as though to whistle. make whoosh sound wout puffing cheeks
o concentrate on feeling abd fall or sink. tighten abd muscles while breathing out to enhance exhalation. count to 7
o use every 2hrs or whenever SOB. inc to 5-10min 4xdaily
controlled coughing use upright position.
• 2 full deep breaths, inhale and hold breath for count of 3 cough 2-3x wout inhaling between
• if pt has incision teach them to place hands or pillow over incisional area. press gently

44
Q

hgb
hct
k
na

A

Hgb 136-170 g/L
HCT 0.40-0.52 L/L
Na 135-145 mmol/L
K 3.5-5.0 mmol/L

45
Q

nutrients to support wound healing

A

Min 1500 kcal/day
Protein
Vitamin A and C
Zinc

46
Q

considerations about bowel fx postop

A
  • constipation is common after sx
  • Dec activity, intake and opioids cause this.
  • If abdm is not distended and BS are present and patient has not had a bowel movement on 2nd or 3rd day the physician should be notified (laxative will be given)
47
Q

how will persons GI tract feel after sx

A

Gynaecological sx are worst for causing abdominal pain
• Manipulation of GI tract can cause less peristalsis for 24-48 hours post-op and swallowed air can get trapped and cause distention and fullness want pt to reposition, ambulate to prevent this

48
Q

reintroducing feeding postop

who should you not feed

A

Listen to BS before feeding people. when they are heard it indicates full peristalsis
Want them to pass flatus
start w clear fluids
• Diet should be resumed as early as possible  stimulates gastric secretions + peristalsis; eating will speed normal GI fx

Dont feed anyone w abdominal surgery

49
Q

what could happen if GI peristalsis doesnt return

whats this called

A

• Paralytic ileus + intestinal obstruction = possible complications

50
Q

which drugs interfere with urination

A

• Anesthetics, anticholinergics + opioids interfere with perception of bladder fullness, urge to urinate, and ability to initiate urinating

51
Q

tricks to get people to pee

A

• Aided by water running + warmth over perineum

52
Q

DVT s/s

A

• DVT = pain or cramp, followed by swelling of limb, fever, chills, diaphoresis

53
Q

1 thing that should be encouraged to prevent delirium and 1 note about the environment they shoud be in

A

o Keeping pt in well lit room close to nursing unit can help prevent sensory deprivation
o Physical deterioration exacerbates it – don’t neglect physical activity

54
Q

how to maint safe environment post op

how often to check on pt

A

Assess LOC and blood pressure before ambulating
CALL BELLS within reach!! Side tables within reach.
Restore senses (glasses, hearing aids, etc.)
Ambulate “with” at first
Never leave alone in the bathroom until certain they won’t faint
Check your patient Q1H
