NUR 354 Pharmacology II Module 2 Notes:
Shock, Hematopoietic, Neoplastic Drugs
Questions And Answers
Blood or blood products - ANS What drugs are administered to restore fluid volume when
more than 30% of fluid volume is lost?
replace plasma volume and supply red blood cells - ANS MOA of blood/blood products
whole blood, plasma protein fraction, fresh-frozen plasma, packed red blood cells - ANS
What are the components of blood/blood products?
maintain plasma osmotic pressure; transport substances through blood - ANS MOA of
colloid agents
Plasma volume expanders - ANS What are colloid agents also called?
restoration of plasma volume and blood proteins - ANS Primary use of colloid agents
normal human serum albumin, plasma protein fraction, serum globulins - ANS What are
examples of blood colloids?
Dextran, hetastarch - ANS What are examples of nonblood-product colloids?
can readily leave blood and enter cells to replace fluids that have been lost; promote urine
output - ANS MOA of crystalloids
True - ANS True or false: crystalloid concentrations resemble the concentrations of
plasma
normal saline, lactated ringer's, PlasmaLyte, hypertonic saline, D5W - ANS What are
examples of crystalloids?
hypertonic, hypotonic, isotonic - ANS What are the three classifications of crystalloids?
normal serum albumin - ANS Prototype for Colloid Agent (Fluid Replacement Agent)
, maintain plasma osmotic pressure; transport substances through blood - ANS MOA of
normal serum albumin
allergies; protein overload - ANS Adverse effects of normal serum albumin
act directly on alpha-adrenergic receptors to raise blood pressure - ANS MOA of
Vasoconstrictors/Vasopressors for shock
True - ANS True or false: vasoconstrictors/vasopressors have positive inotropic effects
treat shock and cardiac arrest - ANS Primary use for vasoconstrictors/vasopressors
dopamine, norepinephrine, phenylephrine, epinephrine - ANS Examples of
vasoconstrictors/vasopressors
norepinephrine (Levophed) - ANS Prototype for vasoconstrictors/vasopressors
to act directly on alpha-adrenergic receptors to raise blood pressure; also have positive inotropic
effects - ANS MOA of norepinephrine
vasopressors strengthen heart contractility (stronger heart contractions), strengthening cardiac
output and help organs get blood and oxygen that they need to survive - ANS What does
it mean that vasopressors have positive inotropic effects?
nonselective adrenergic agonist - ANS Pharmacologic class of norepinephrine
(Levophed)
vasopressor - ANS Therapeutic class of norepinephrine (Levophed)
phentolamine - ANS If extravasation of norepinephrine occurs, what medication can you
administer as an antidote?
immediate - ANS Onset of norepinephrine
1-2 min - ANS Peak of norepinephrine
1-2 min - ANS duration of norepinephrine
alpha and beta blockers (may antagonize the drug's vasopressor effects); ergot alkaloids and
tricyclic antidepressants may potentiate vasopressor effects; use with MAOIs may lead to acute
hypertensive crisis - ANS Drug interactions with norepinephrine
increase strength of myocardial contraction; increase cardiac output - ANS MOA of
inotropic drugs for shock
