Hondros 4th Lpn Term

nursing process related to infusion therapy

ADPIE, assessment, diagnosis, planning, implemenatation, evaluation

sources of law related to infusion therapy

constitutional, statutory, administrative, common law

assault

threatening a pt

battery

actually smacking the dude

negligence

failing to do something a reasonable person would do

malpractice

form of negligence in which a professional fails to do adhere to a practice within their profession

4 components of malpractice

-must be established that the nurse had a duty to the pt
-breach of standard of care or failure to carry out duty must be proven
-pt must suffer actual harm or injury
-must be a casual relationship between the breach of care and the injury

standards of care

focuses on the recipient of care

standards of nursing practice

focuses on the provider

6 rights

-right pt
-right dose
-right time
-right route
-right documentation

code of ethics based on

-autonomy
-beneficence
-nonmaleficence
-veracity
-fidelity
-justice

quality pt management

systematic process to ensure desired pt outcome

sentinel event

unanticipated event that causes the death, serious physical or psychological injury to a person; not related to a pts actual course of illness

average daily I&O of water (adult)

1500-2500mL

average output of water (adult)

40-50mL

output fluids

urine, diarrhea, vomit, nasogastric suction, chest tube drainage, surgical wound drainage. If it leaks something, measure it!

GFR

125mL hour or 180L per day

diffusion

movement of particles in all directions thru solution or gas.
-movement higher to lower concentration

osmosis

movement of WATER from an area of lwer concentration to high concentration

hypertonic solutions

pulls fluids from cells, makes them shrink. Think cold water to a penis

isotonic solutions

same osmotic pressure. Doesn't cause any kind of fluid shift

hypotonic solutions

low osmotic pressure. Fluids move in cells causing them to enlarge and swell

filtration

transfer of water and solutions from high to low pressure

cations

positive charge ions

anions

negative charged ions

positive should equal negative

cations=anions

anion electrolytes

-chloride
-bicarbonate
-phosphate
-sulfate

cation electrolytes

-sodium
-potassium
-calcium
-magnessium

sodium

-most abundant electrolyte
-norm 135-145mEq/L

functions of sodium

regs water balance, controls extracellular fluid volume, stimulates nerve impulses, control contractility of muscles

factors that cause sodium imbalance

-deficit caused by excessive vomiting
-change in chloride content (remember, chloride ALWAYS goes with sodium)
-change in quantity of water in extracellular fluid (ECF)

hyponatremia

-can occur with water excess
-body attempts to compensate by decreasing water excretion
-pt likely to have potassium imbalance because of fluid moving in cells, pushing potassium out of cells

hyponatremia S/S

-muscle weakness
-muscle twitching
-decreased skin turgor
-headache, tremor, seizures, coma

hyponatremia tx

-replace sodium/fluid loss
-restore norm ECF volumes
-correct other electrolyte imbalances (potassium and bicarb)

hypernatremia

-occurs with water loss
-body attempts to correct by conserving water thru renal absorption
-causes fluid to shift from cells into interstitial spaces causing cellular dehydration (uh oh)

hypernatremia S/S

-thirst
-elevated body temp
-swollen tongue, flushed skinpo
-red, dry and sticky mucous membranes
-disorientation, irritability, hyperactivity

hypernatremia tx

-infuse hypotonic solution (0.9 NS)
-use of diurectics, inducing excretion of water and sodium

potassium

-norm 3.5-5.0 mEq/L
-kidneys control excretion of potassium
-main function is to regulate water and electrolyte content within cells
-no effective stroage for K+, must be ingested daily

functions of K+

-effects skeletal and cardiac muscles
-can cause myocardial irritability and rhythm
-respnsible for nerve pulse transmission

hypokalemia

-major cause is loss thru renal secretion
-can be depleted thru GI losses, vomiting and use of diuretics
-can effect cardiac and skeletal function

hypokalemia tx

-increase of K+ supplements
-IV K+ treatment
-NEVER give K+ IV push (that is what lethal injection is)

hypokalemia S/S

-decreased GI, skeletal muscle, cardiac function
-decreased reflexes
-rapid, weak, irregular pulse
-low bp
-decreased BM
-muscle weakness or irritability

hyperkalemia

-major cause is renal disease
-can cause cardiac arrest

hyperkalemia S/S

-EKG changes
-muscle weakness
-flaccid paralysis
-anxiety, nausea, cramping, diarrhea

hyperkalemia tx

-restrict diet, d/c K+ supplements
-admin calcium gluconate
-IV sodium bicarb (causes shift of K+ into cells)
-admin regular insulin and hypertonic solution
-peritoneal dialysis or hemodialysis

calcium

-norm 9-11 mEq/L
-99% is in bones and teeth
-best sources are thru milk and cheese, and calcium cheeseburgers with lots of mayo and onions, Maybe a little bar b q sauce too

hypocalcemia

-caused by excessive loss thru diarrhea, inadeqate dietary intake, surgical removal of parathyroid function, pancreatic or small bowel disease

hypocalcemia tx

-must treat underlying cause
-calcium gluconate and calcium supplements

hypocalcemia S/S

-muscle cramps
-arrhythmias
-numbness or tingling of fingers
-tonic-clonic seizures
-Chvosteks sign
-Trousseaus sign

Chvostek's Sign

contraction of facial muscles in response to light tap over facial nerve in front of ear. Or you can just punch them in the face and if they look mad then they're normal. If they looked shocked then they're hypocalcemic

Trousseau's Sign

carpal spasm induced by inflating a bp cuff above systolic pressure for a few minutes

hypercalcemia

-occurs when calcium in bones begins to circulate with blood; occur with immobilization

hypercalcemia causes

-hyperparathyroidism
-Paget's disease
-multiple fractures
-over use of calcium containing antacids

hypercalcemia tx

-treat underlying cause
-organic phosphate salts
-hemodialysis or peritoneal dialysis
-Lasix to prevent fluid overload
-Calcitonin to lower serum levels
-Plicamycin to stop bone reabsorption

Hypercalcemia S/S

-lethargy
-headache
-muscle flaccidity
-N,V
-anorexia
-constipation hypertension
-polyuria

isotonic solutions examples

normal saline (NS), D5W, WD40, lactaded ringers (wish I knew what a lactated ringer was)

longitudinal burrows

lines on the tongue

hypovolemia S/S

low bp, high HR, high HNH

hypervolemia S/S

-HTN, bounding pulse, tachycardia, edema, crackels
