Q

Atrial Natriuretic Peptide (ANP)

A

opposite of aldosterone - so causes the excretion of sodium and water
Is released as the heart is stretched to fix FVE

2
Q

Antidiuretic hormone

A

causes you to retain WATER WATER WATER

3
Q

With urine specific gravity, sodium, and HCT concentrated makes the #s go

A

up

4
Q

With urine specific gravity, sodium, and HCT dilute makes the #s go

A

down

5
Q

Not enough antidiuretic hormone

A
Diuresis Water
Fluid Volume Deficit
Diabetes Insipidus - nothing to do with blood sugar
Blood Concentrated (so increased #s)
Urine Dilute (so decreased #s)
Increased urine output
6
Q

When not enough antidiuretic hormone number one thing to worry about is?

A

shock

7
Q

What are some potential causes of antidiuretic hormone problems

A

(anything that upsets pitutary gland)

craniotomy, head injury, sinus surgery, transphenoidal hypophysectomy

8
Q

Any condition that can lead to and increase in ICP can lead to *

A

an antidiuretic hormone problem

9
Q

Pt had transphenoidal hypophysectomy and voided 1300 ml worry about

A

pt getting diabetes incipidus and developing shock

10
Q

If going into FVE where will you hear “wet” sounds first?

A

posteriorly in the bases of the lungs

11
Q

If in FVE what happens to pulse

A

increases and will be full and bounding
the heart is now pumping harder to keep fluid moving forwards and not backwards (if goes backwards will lead to HF and pulmonary edema)

12
Q

any acute weight gain is

A

water not fat

13
Q

MORE VOLUME…. MORE

A

PRESSURE

14
Q

If fluid retention then think what first? *

A

heart problem

15
Q

Bed rest and diuresis

A

Bed rest induces diuresis by release of ANP (opposite of aldactone) and decreases production of ADH

16
Q

Bed rest can increase risk for

A

DVT, dehydration, kidney stones, pneumonia, and constipation (all because bed rest causes diuresis and can go into FVD)

17
Q

If pt on bed rest what is very important to do?

A

push fluids because bed rest induces diuresis

18
Q

anytime you see an assessment or evaluation you should be looking for the presence or absence of

A

PERTINENT signs and symptoms

19
Q

Give IV fluids slowly to

A

elderly, very young, and hx of kidney disease

can put in FVE very fast

20
Q

If pt loosing fluid worry about

A

shock

21
Q

Pts with ascites important problems

A

breathing problems (fluid pushing on diaphragm) and hypotension (fluid in wrong spot)

22
Q

PID (particle induced diuresis) with diabetes

A

sugar particles have to come out in volume and is why the diabetic pt gets diuresis

23
Q

When pt goes from polyuria to oliguria to anuria worry about

A

renal failure

24
Q

with polyuria think what first?*

A

shock

25
Q

FVD pts at risk for

A

orthostatic hypotension because there is less volume and less pressure

26
Q

in FVD respirations are

A

increased because body thinks hypoxic so increases rate to fix hypoxia

27
Q

Isotonic solutions

solutions can cause FVE, HTN, or Hypernatremia

32
Q

Only solution that can cause hypernatremia

A

isotonic

33
Q

Hypotonic solutions definition:

A

go into vascular space then shift out into the cells to replace cellular fluid
they rehydrate but do not cause hypertension (won’t increase bp because don’t stay in vascular space)

34
Q

Hypotonic solutions:

A

D2.5W, 1/2 NS, 0.33% NS

35
Q

Uses of hypotonic solutions

A

HTN, renal disease, cardiac disease, N/V, burns, hemorrhage, used for dilution with hypernatremia and for cellular rehydration

36

With hypotonic solutions watch for

A

cellular edema because this fluid is moving out into cells which could lead to FVD and decreased bp

37
Q

hypertonic =

A

colloid

38
Q

isotonic =

A

cyrstaloid

39
Q

hypertonic solutions definition:

A

D10W (sugar), 3% NS, 5% NS (salt), D5LR, D51/2 NS, TPN, Albumin

42
Q

Uses of hypertonic solutions

A

hyponatremia, pt who has shifted large amounts of vascular volume to 3rd space, severe edema, burns, or ascites

43

a hypertonic solution will

A

return the fluid volume to the vascular space

44
Q

with hypertonic solutions watch for

A

fluid volume excess
monitor bp, pulse, and CVP
especially with 3% NS or 5%NS

45

Insulin carries what into cell

A

glucose and potassium

so anytime give IV insulin worry about hypoglycemia and hypokalemia

46
Q

hyperventilation and CO2

eliminate CO2

47
Q

hypoventilation and CO2

A

retain CO2

48
Q

causes of respiratory acidosis

A

(retaining CO2 and HYPOventilation)
mild abdominal incision (can’t take in deep breaths), narcotics and sleeping pills ( repress breathing), pneumothorax, collapsed lung, pneumonia (sticky secretions)

49
Q

respiratory acidosis s/s

A

h/a, confused, sleepy
can go into coma
hypoxic (early s/s restless and tachycardia)

50
Q

If restless pt think what 1st

A

hypoxia

51
Q

to treat respiratory acidosis you

A

need to fix the breathing problem

so elevate bed, deep breathing, suctioning, voldyne

52
Q

respiratory acidosis hypo/hyperventilating

A

hypo - retaining CO2 that’s an acid

53
Q

respiratory alkalosis hypo/hyperventilating

A

hyper - losing CO2 (acid) and why alkalotic

54
Q

respiratory alkalosis causes

A

hyperventilation
hysterical
acute aspirin overdose (stimulates respiratory center in the brain)
-pt breathing too fast and removing CO2

55
Q

respiratory alkalosis s/s

A

lightheaded
faint
perioral numbness
numbness and tingling in fingers and toes

56
Q

respiratory alkalosis treatment

A

breathing into paper bag to force back CO2

may sedate pt to decrease respiratory rate

57
Q

metabolic acidosis causes

A

(too much hydrogen (acid) and too little bicarb (base)
DKA - body doesn’t have insulin to bring glucose into cells so breaks down body fats for energry leads to ketones (acids)
Starvation - starving for glucose so break down protein and produce ketones (acids)
Renal Failure - no longer can filter out acids or retain bases
Severe diarrhea - lower GI has lots of bases but when diarrhea loses bases

58
Q

metabolic acidosis s/s

A

hyperkalemia - muscle twitching/weakness/flaccid, arrhythmias
increased respiratory rate - trying to blow off the acid
increased serum potassium level

59
Q

see what kind of respirations with DKA

A

kausmals because the body has too much acid (resulting from ketones) and body tries to blow off CO2 to become less acidic

60
Q

diarrhea what type of acid/base imbalance

A

metabolic acidosis

comes out of your acidosis

61
Q

drug to help metabolic acidosis

A

IV push sodium bicarb - will not fix but buy time to figure out cause
will get pH back in normal range then figure out cause

62
Q

metabolic alkalosis causes

A

loss of upper GI contents (acid in stomach)
too many antacids (so too much bases)
too much IV bicarb

63
Q

metabolic alkalosis s/s

A

LOC alterations
serum K levels will go down
respirations will decrease to try to hold onto CO2

64

A

hyperkalemia

66
Q

metabolic alkalosis = (K)

A

hypokalemia

67
Q

After a burn why does plasma seep out into the tissue?

A

increased capillary permeability (leaking) - the vessels are damaged from heat so thats why they leak
vascular volume is decreased so at risk for shock
occurs 1st 24 hours after burn

68
Q

After a burn what happens to pulse and cardiac output

A
pulse increases (because in FVD)
cardiac output decreases - because less volume
69
Q

After a burn what happens to urine output

A

decreased because either kidneys trying to hold onto fluid or they aren’t being perfused (only takes 20 mins of poor kidney perfusion to have kidney necrosis)

70
Q

After a burn why is epinephrine excreted

A

makes you vasoconstrict to shunt blood to vital organs and help to increase bp

71
Q

After a burn why are ADH and aldosterone secreted?

A

aldosterone - retain Na and water
ADH - retain water
therefore blood volume will go up

72
Q

problem with carbon monoxide

A

normally oxygen binds with hemoglobin but carbon monoxide travels much faster than oxygen therefore gets to hemoglobin faster and now oxygen can’t bind now pt is hypoxic

73
Q

color of carbon monoxide pt

A

cherry red not blue

74
Q

treatment for carbon monoxide poisoning

A

100% O2 - trying to increase the chances of O2 to bind with hemoglobin instead of carbon monoxide

75
Q

What would MD do if pt has burns to chest/neck/face?

A

intabate! - do this before trach because less invasive

airway will swell then will have to trach so intabate before have to trach

76
Q

Rule of Nines

A
Head and neck 9%
Front of trunk 18%
Back of trunk 18%
Arms (each) 9%
Genitals 1%
Legs (each) 18%
77
Q

Parkland formula

A

(4ml of LR) x (weight in kg) x (% of TBSA burned) = total fluid requirement for the 1st 24 hours after burn
1st 8 hours

78
Q

Fluid therapy for burns depends on what

A

the time the injury occurred not when the treatment was started

79
Q

restless burn pt means

A

inadequate fluid replacement, pain, or hypoxia

hypoxia is the priority, pain never killed anyone

80
Q

in burn pts how would you tell if fluid volume is adequate -

A

urine output
not weight because burn pts getting fluids fast and causes an increase in weight gain which makes urine output a better indicator

81
Q

Emergency burn management

A

put cool water! (not ice water - ice causes vasoconstriction)
remove jewelry to prevent swelling
place blanket to hold in body heat and keep out germs
remove non-adherent clothing and cover burn with a clean dry cloth

82
Q

Shallow respirations means?

  2. skin color
  3. skin temp
  4. cap refill
87
Q

escharotomy -

A

relieves the pressure and restores the circulation, cutes through the eschar

88
Q

fasciotomy -

A

relieves the pressure and restores the circulation, but cut is much deeper into tissue than escharotomy, cut goes through the eschar

89
Q

why when insert foley cath no urine returns?

A

kidneys are attempting to retain fluid or they aren’t being perfused adequately

90
Q

If you see brown or red urine in burn pt what would you do?

A

call the MD
this happens because will have muscle and tissue destruction then myoglobin is released in urine, then worry about renal failure
want to increase fluids to flush out kidneys
mannitol used to flush out kidneys - exception to the no diuretics to burn pts

91
Q

If no urine output or less than 30 ml/hour what would you worry about?

A

kidney failure

92
Q

Why burn pt NPO and have an NG tube hooked to suction?

A

because they can develop a paralytic illeus - which could cause gastric secretions to build up in stomach and potential to aspirate

93
Q

Why burn pts can get a paralytic illeus?

A

Decreased vascular volume - blood shunted to vital organs and gut not perfused
Decreased GI motility - normal stress response
Hyperkalemia - symptom of muscle weakness - intestines are smooth muscle

94
Q

if pt doesn’t have bowel sounds, what will happen to the abdominal girth?

A

increases

95
Q

Diet for burn pts

A

high protein and vitamin C*, need maximum nutrition - they are in a hypermetabolic states

96
Q

NG tube removed when

A

hear bowl sounds

97
Q

when start GI what should you measure to ensure the supplement is moving through GI tract

A

gastric residuals
Order to hold feeding if >50 - means parstolic activity is very slow so hold feeding and put residual back in to prevent fluid/electrolyte imbalances

98
Q

lab work to ensure proper nutrition and a positive nitrogen balance?

A

prealbumin, total protein, or albumin

prealbumin - most sensitive indicator of overall nutritional status

99
Q

what to do if burns on neck?

A

hyperextend the neck, head is back

no pillows, promotes chin-to-chest

100
Q

what is eschar

A

necrotic dead tissue
has to be removed - new tissue can not regenerate if not removed
also, bacteria can grow in bacteria

101
Q

If see skin graft hanging by sutures then

SQ emphysema - air under the tissues
feels like rice cripys sounds
EMERGENCY!

143
Q

respiratory depression

A

depressed

144
Q

sputum specimen

A

should take 1st in the morning
should be sterile - don’t want mouth touching cup
first the pt should rinse mouth out with water - to decrease the bacteria in the mouth

145
Q

Lobectomy

A

part of the lung is removed
surgical side up
will have chest tubes

146
Q

Pneumonectomy

A

entire lung is removed
position on affected side (surgical side down, good lung up) - so lung can expand and not get pneumonia
No chest tubes - because there’s no lung
Avoid lateral positioning (don’t turn all the way on their side) - can lead to mediastinal shift!!

147
Q

total laryngectomy

A

removal of vocal cords, epiglottis, thyroid cartilage
because epiglottis is removed at risk for aspiration
pt will have a permanent trachostomy and breath out of stoma the rest of their life

148

post opp position after total laryngectomy

A

mid folwers

149
Q

if emergency and have the options call MD or check VS

rupture of innominate artery!

begins with bleeding massively from trach

151
Q

with a total laryngectomy ALL breathing is

A

done through the stoma

152
Q

If trach comes out

A

if can’t get new sterile trach then run and insert dirty trach
better to be alive with infection then dead infection free

153
Q

Bloom Singer device

A

connection is made between the trachea and esophagus
pt can insert soft plastic device and move air from lungs to trachea and then over to esophagus and out of mouth
tongue and lips can form words with the rush of air
nothing can be pulled from esophagus into lungs - so don’t have to worry about aspiration

154
Q
Can pt with total laryngectomy:
whistle?
use straw?
smoke?
swim?
A

whistle? no
use straw? no
smoke? not recommended, but could
swim? no

155

suctioning with total laryngectomy

A

sterile technique
hyperoxygenate before and after
stop advancing catheter when you MEET RESISTANCE* or pt coughs
apply suction on the way out
do intermittent suction no longer than 10 seconds
watch for arrhythmias

156
Q

If suctioning and heart rate drops

A

vagus nerve was stimulate, pt is not hypoxic

stop suctioning and hyperoxygenate

157
Q

Colorectal cancer most frequent site of metastasis

A

liver

so take bleeding precautions

158
Q

colectomy

A

part of the colon removed

may not need colostomy, depends on how much is removed

159
Q

abdominoperineal resection

abdominoperineal resection, thrombocytopenic, or immunosuppressed

161
Q

major symptom of bladder cancer

A

painless intermittent gross/microscopic hematuria

162
Q

illeal conduit

A

piece of the ileum is turned into a bladder
ureters are placed in one end is brought to the abdominal surface as a stoma
so urostomy!
need to flush out so drink lots of fluid (2,000-3,000)
now normal to have mucus - because bladder made from part of intestine
change appliance in morning (because output will be its lowest
Also, its ok to place a little piece of 4x4 inside the stoma during skin care to absorb urine just don’t forget to remove it

163
Q

after any urinary surgery with males chance of

A

impotent

164
Q

most common sign of prostate cancer

A

painless hematuria
(others: hesitancy, frequency, frequent infections - because can’t empty bladder completely, nocturia, urgency, dribbling)

165
Q

radical prostatectomy

A

biopsy must be done prior to surgery for confirmation of prostate cancer
take out the prostate and if pt is cancer free then no metastasis
may have erectile dysfunction due to pudendal nerve damage
may have incotinence
pt is sterile

166
Q

prostatectomy TURP

A

transurethral resection of the prostate
used to help urine flow NOT a cure for prostate
no incision
excessive bleeding complication - worried about clogging up kidneys so use continuous bladder irrigation to maintain patency and flush out clots

167
Q

Can you manually irrigate a catheter with a fresh surgery pt?

A

NEVER without MD order

168
Q

When walk into room assess tubing for kinks or bladder distention on pt 1st

take out stomach but leave some if can
fowlers position
will have NG tube - do not reposition

172
Q

complications of gastrectomy

A

dumping syndrome

vitamin B12 deficient anemia

173
Q

no stomach r/t vitamin B12

A

no stomach then no instrinic factor then can’t absorb PO B12 can’t make good RBC so pt is anemic
will get B12 shots every week for a month then monthly after that

174
Q

Schilling’s Test*

A

measures the urinary excretion of vitamin B12 for diagnosis of PERNICOUS ANEMIA not iron deficiency

175
Q

You need what to produce hormones?

A

Dietary iodine (different than drug)

176
Q

Thyroid hormones give us

A

energy!

177
Q

Diagnosing graves disease

A

(Hyperthyroidism)
draw serum T4 levels -increased
thyroid scan - enlarged thyroid

178
Q

what must pts do prior to thyroid scan?

A

pts must discontinue any iodine containing medication 1 week prior

179
Q

eu =

A
normal 
so euthyroid (normal thyroid)
180
Q

tyroidectomy pt care

A

Teach how to support neck because incision on front of neck and don’t want tension on suture lines
elevate HOB
check for bleeding behind the neck (pooling)
will need more calories
assess for recurrent laryngeal nerve damage by listening for hoarsness

181
Q

thyroidectomy can lead to what

A

vocal cord paralysis, if both then possibly airway obstruction will occur then require immediate trach

182
Q

When would you trach at bedside of thyroidectomy

A

swelling
recurrent laryngeal nerve damage (vocal cord paralysis)
hypocalcemia
- assess for parathyroid hormone by the s/s of hypocalcemia (not sedated, rigid and tight muscles) - could possibly have seizure

183
Q

People with hypothyroidism tend to have underlying

A

CAD

so monitor for chest pain and rhythm changes when giving meds that increase HR and BP

184
Q

the parathyroid secretes

A

parathormone which makes you pull calcium from the bones and place it in the blood

185
Q

if too much parathormone then serum Ca will

A

be high

186
Q

if too little parathormone then serum Ca will be

A

low

187
Q

partial parathyroidectomy

A

when take out 2 of your parathyroids to decrease PTH secretion
done when pt hyperparathyroid/hypercalcium/hypophastemia
monitor hypocalcium post opp (non sedated, rigid tight muscles)

188
Q

vanillylmandelic acid test

A

24 hours urine specimen is done to see if pt has pheocromocytoma (adrenal medulla problem)
looking for increased levels of epi and norepi
can’t have anything with vanilla in it for a wk prior
throw away first void and keep the last for 24 hours
have to remain calm for those 24 hours so that epi and norepi don’t increase

189
Q

even though the body secretes steroids normally the adverse effects are going to be more pronounced when the

A

pt is receiving PO or IV steriods

190
Q

too much aldosterone =

A

too much Na and Water
so FVE
decrease serum potassium

191
Q

not enough aldosterone =

A

decrease Na and water
so FVD
increase serum potassium

192

severe hypotension and vascular collapse
can occur when stop taking steroids abruptly
have to taper steroids because body not making on steriods

195
Q

What happens with blood sugar with addison’s disease?

A

Do whatever you can to re-establish the water seal.
Set CDU upright, check all the chambers, and fill the water seal chamber to 2 cm of water.
Have the client deep breathe and cough in case any air went into the pleural space. - will shoot out of tubing
If there is not water in the water seal chamber then air can do what? Collapse the lung

315

Q

open pneumothorax

A

sucking chest wound
opening that allows air into pleural space
stabbing/shooting

take deep breath and hold or humm. - will increase the intra-thoracic pressure so no more air can get into body
