Question 1: Nitroglycerin (Tridil) dosage

Answer:

• - 200 mcg/min

Question 2: Dopamine: intermediate dose range and purpose

Answer:

• to 10 mcg/kg/minute, results in increased renal blood flow, heart rate, cardiac contractility, and cardiac

output

Question 3: Dopamine purpose

Answer:

Perfuse kidneys (low dosage), vasopressor, chronotrop, inotrop

Question 4: Dopamine (Intropin) dosage

Answer:

• - 20 mcg/kg/min, max 50. If dosages >20 to 30 mcg/kg/minute are needed, a more direct-acting

vasopressor may be more beneficial (ie, epinephrine, norepinephrine).

Question 5: Dobutamine normal dosage

Answer:

0.5 - 20 mcg/kg/min IV or IO; Not to exceed 40mcg/kg/min. Heart Failure patients should not exceed 20mcg/kg/min.Question 6: Phenylephrine: mechanism of action

Answer:

Potent, alpha-adrenergic agonist. no beta-adrenergic activity; produces syst. art. vasoconstriction. Incr in systemic vasc resistance result in dose dep inc in syst and dias blood pressure and reductions in HR & cardiac output esp in pts w/heart failure.

Question 7: Dopamine max dose

Answer:

50mcg/kg/min Question 8: Dopamine: Mechanism of action

Answer:

lower doses are dopaminergic stimulating - renal and mesenteric vasodilation, higher doses also are both dopaminergic and beta1-adrenergic stimulating and produce cardiac stimulation and renal vasodilation; large doses stimulate alpha-adrenergic receptors Question 9: Dobutamine: Mechanism of action

Answer:

Dobutamine stimulates myocardial beta1-adrenergic receptors resulting in increased contractility and heart rate. Some vasodilation in addition to the inotropic and chronotropic action.

Question 10: Dobutamine max dose

Answer:

• Heart failure patients not to exceed 20

Question 11: Dopamine: high dose range and purpose

Answer:

>10 mcg/kg/minute, alpha-adrenergic effects begin to predominate, resulting in vasoconstriction, increased blood pressure, in addition to increased heart rate, cardiac contractility, and cardiac output due to beta-adrenergic effects.

Question 12: Epinephrine dosage

Answer:

• - 8 mcg/min

Question 13: If dopamine is raised to >=20mcg/min and the desired effect is not achieved, what is recommended?

Answer:

A more direct vasopressor (ie. epinephrine, norepinephrine) Question 14: Dopamine: low dose range and purpose

Answer:

• to 5 mcg/kg/minute, results in increased renal blood flow and urine output

Question 15: Levophed (Norepinephrine) dosage

Answer:

(IBW) 15 - 25 mcg/min Question 16: Norepinephrine: Mechanism of action

Answer:

Stimulates beta1-adrenergic receptors and alpha-adrenergic receptors causing increased contractility and heart rate as well as vasoconstriction; alpha effects (vasoconstriction) are greater than beta effects (inotropic and chronotropic effects)

Question 17: Dobutamine purpose

Answer:

• Inotrop

Question 18: Phenylephrine dosage

Answer:

100 to 180 mcg/minute, or alternatively, 0.5 mcg/kg/minute; titrate to desired response.
