- list steps for removing nasogastric tube?
-
assess for bowel sounds
place emesis basin/plastic bag on nearby tray
puton gloves/place towel on upper chest
turn of machine/disconnect tube from nasogastric machine
unpin gown or untape from cheek
instill 20 cc of air into tube
loosen tape on nose
remove tube - should you remove nasogastric tube is there are no bowel sounds
- NO
- WHY do you instill 20cc of air into the tube
- to displace secretions back into stomach (decreases risk for aspiration)
- how do you remove the nasogastric tube?
- one quick motion/intruct patient to breathe hold
- what is generalized body edema?
- anasarca
- what is the normal specific gravity of urine
- 1.005-1.026
- decreased bun, hematocrit, sodium, and decreases plasma osmolality are classic signs of?
- fluid volume excess
- what are accuratte indicators of potassium sodium and chloride levels
- plasma levels
- what are the chief complaints for fluid and electrolyte deficits
-
nausea
vomiting
diarrhea
anorexia
fatigue
weakness
weight loss
fever blood loss
excess urine output
change of mental status - what are the chief complaints for fluid and electrolyte excess
-
weight gain
dyspnea
cardiac palpatations
pitting edema
decreased urinary output
mental status - when are plasma sodium, osmolality, hematocrit, and BUN levels elevated
- FLUID VOLUME DEFICIT
- what are generalized characteristics of extracellular fluid deficit
-
flattened neck in supine position
sudden weight loss
peripheral veins taking +5 refill
decreased skin tugor
dry mucous membrane
furrowed tongue
speech changes
muscle weakness
soft and sunken eyballs
depressed fontanels in infant
moderate loss fever
severe loss subnormal temp - what are some cardiac characteristics of extralcellular fluid deficit
-
orthostatic hypotension
tachycardia
weak,thready pulse
narrow pulse pressures - what are some gastrointestinal characteristics of extralcellular fluid deficit
- constipation or decrease in number and moisture of stools
- when should you notify a physician of weight or fluid loss
- if client experiences a rapid unexpected weight loss of 3lb a day
- what is ascites
- generalized fluid accumulation in large body spaces
- what is more dangerous intracellular or extracellular fluid deficit
- intracellular because of potential problem with cell functions
- what are defining charachteristics of intracellular dehydration
-
fever
thirst
central nervous system changes - what triggers thirst mechanism
- osmoreceptors in hypothalmus
- what are some early signs of cerebral manifestations from intracellular dehydrations
-
restlessness
headache
irritability
then confusion - what are some late signs of cerebral manifestations from intracellular dehydrations
- seizures, coma
- what are some general characteristics of extracellular fluid excess
-
weakness/fatigue
body edema
sudden weight gain
peripheral vein distension
bulging fontanels in an infant - what are some pulmonary characteristics of extracellular fluid excess
-
increased respiratory rate
crackles
pulmonary edema
progressive worsening of dsypnea - what are some cardiac characteristics of extracellular fluid excess
-
tachycardia
bounding pulse
hypertension
third heart sound
pericardial efusion - what are some gastrointestinal characteristics of extracellular fluid excess
-
anorexia
nausea
vomiting - what are some renal characteristics of extracellular fluid excess
-
increased output if kidney can compensate
decreased output if kidneys are damaged - how much water does a well adult need for cellular functions
- 2 to 2.5 liters
- HOW much fluid should you drink if you have a fever
-
30 to 100 ml hourly
240ml if fever is higher than 100 - if hypertonic supplement or feeding is given how much water should be given
- 1 ml of water per one calorie of feeding
- what is forcing fluids
- giving patient up to 3000ml of fluids in 24 hours for moderate to severe fluid loss
- how much fluid should the patient recieve in the daytime for forced fluids
- usually 3/4 of total
- how much fluid should be taken in during exercise
- 8-12 ounces for every 20-30 minutes
- what are normal arterial blood gas levels ph
- 7.35-7.45
- what patients are high risk for metabolic acidosis
-
end stage renal disease
severe diarrhea
hypoxia
hyperglycemia - what are early neurological signs of metabolic acidosis
-
headaches
decreased level of consciencness -
when fluid overload is the etiology of hyponatremia
what is the best intervention - fluid restrictions
- if hyponatremia is due to true na deficit what are the interventions
-
oral/tube/iv supplemenation
digitalis or diuretic for cardiac overload - how should oral potassium be given
- with food because it is a gi irritant
- how can iv potassium be given
- only in dilluted form
- what is the maintenace dose of potassiumis
- 40-80 milliequalvilents
- is potassium a venous irittant
- yes
- what do you do if patient feels pain at iv site
- infusion rate can be slowed or potassium can be further diluted
- if urine drops to less than 30ml/hr for at least 2 hours when an patient has potassium balance what should u do
- notify physician
- what may be issued to excrete potassium from the body in a case of hyperkalemia
- giving sodium kayexalate in oral or rectal form
- if potassium levels has caused significant cardiac conductions what can the physician order
- iv glucose and insulin to promote temporary shifting potassium from plasma into cells
- calcium must be taken with what to promote absorbtion
- vitamin d
- what should patients avoid if hypocalcemia is caused by hypothroidism
- milk and carbonated beverages
- calcium defiencincy also increased patients chance for
- bleeding
- if hypercalcemia is present teach patient to
- strain urine for calculi
- what should you access for to indicate magnesium balance has occured
- return of deep tendon reflexes
- what are phospate excesses treated with
- calcium or aluminum supplements
