,oxycodone 1/2x as strong as morphine
1 mg = 0.5 mg morphine
hydrocodone 1/3x as strong as morphine
1 mg = 0.33 mg morphine
codeine 1/20x as strong as morphine
1 mg = 0.05 mg morphine
parenteral into the bloodstream
enteral into the GI tract
infusion for the purpose of this course: administration of
MORE THAN 100 mL
piggyback the administration of a medication mixed in a small
volume of solution that is "added on" to an existing
port
IV push for the purposes of this course:
- a volume of medication LESS THAN 10 mL
- a medication that is INFUSED in less than 10 mL
osmolarity the concentration of a solution expresses as the total
number of solute particles per liter (mOsm/L)
,osmosis the movement of a solution (water) from an area of
lower concentration to an area of higher
concentration (goes from an area with more water to
an area with less watter)
diffusion the movement of a solute (oxygen/CO2) from an area
of high concentration to an area of low concentration
parenteral infusion - purpose - provide maintenance requirements for fluids and
electrolytes
- replace previous/concurrent losses
- provide nutrition
- provide a mechanism for the administration of
medications and/or transfusion of blood/blood
components
Isotonic IV solution osmolarity 270 - 375 mOsm/L
HYPERtonic IV solution osmolarity greater than (>) 375 mOsm/L
HYPOtonic IV solution osmolarity less than (<) 250 mOsm/L
isotonic IV solutions - uses - standard hydration (expands the volume of fluid in
teh intravascular system)
- dehydration (burns, GI loss, bleeding)
- sodim replacement
- metabolic acidosis (like DKA)
- blood transfusions
- medication diluent
- fluid challenges (to assess renal function//prove
hypovolemia)
, Isotonic IV fluids - nursing - monitor for fluid overload (especially in elderly, CHF,
considerations and HTN patients)
- monitor potassium (may cause hypokalemia)
- monitor sodium (may cause hypernatremia)
- lactated ringers CONTRAINDICATED:
- liver disease and alkalosis (bicarbonate production),
lactic acidosis
Hypertonic IV fluids - uses to correct fluid/electrolyte imbalances by moving
water OUT OF the body's cells and INTO the vascular
space
- treats severe hypovolemia (shock)
- replaces sodium in severe deficits
- used to decrease cellular swelling (in a head trauma)
- needed to replace nutrition/protein
hypertonic IV fluids - nursing - monitor closely for circulatory overload
considerations - do NOT administer to patients with CELLULAR
dehydration (like in DKA)
- should NOT be given to patients with heart/kidney
disease
- central line administration is preferred (highly
corrosive)
