Vasopressors Flashcards
1
Q
epinephrine: class
A
- adrenergic agonist of alpha 1/2, beta 1/2
- anti-asthma
- bronchodilator
- catecholamine
2
Q
epinephrine: MOA
A
- sympathomimetic
- on alpha Rs–vasoconstriction
3
Q
epinephrine: indications on alpha 1 receptors
A
- vasoconstriction
- delay absorption of local anethetics
- control superficial bleeding
- elevate BP
4
Q
epinephrine: indications on beta 1 receptors
A
- overcome AV heart block
- restore cardiac fcn in pts in cardiac arrest with v fib, pulseless v tach, pulseless electrical activity, asystole
5
Q
epinephrine: indications on beta 2 receptors
A
- bronchodilation of pts with asthma
6
Q
epinephrine: indication due to activation of both alpha and beta receptors
A
- anaphylactic shock
7
Q
epinephrine: SEs
A
- angina
- hyperglycemia
8
Q
epinephrine: ADRs
A
- HTN crisis
- dysrhythmias
- necrosis following extravasation
9
Q
epinephrine: nursing implications
A
- exercise caution when administering IV b/c can cause extravasation
- monitor blood glucose
- monitor EKG
- administer 2 for anaphylaxis
- effects of epi can be modified by MAO inhibitors, TCAs, anesthetics, adrenergic blocking agents
10
Q
norepinephrine: class
A
- adrenergic agonist
- works on alpha 1/2, beta 1
- catecholamine
- vasopressor
11
Q
norepinephrine: MOA
A
- Stimulates alpha-adrenergic receptors located mainly in blood vessels, causing constriction of both capacitance and resistance vessels.
- Also has minor beta-adrenergic activity (myocardial stimulation).
12
Q
norepinephrine: indications
A
- hypotensive state
- cardiac arrest
13
Q
norepinephrine: SEs
A
- angina
14
Q
norepinephrine: ADRs
A
- HTN crisis
- dysrhythmias
- necrosis following extravasation
15
Q
norepinephrine: nursing implications
A
- effects of NE can be modified by MAO inhibitors, TCAs, anesthetics, adrenergic blocking agents
- exercise caution when administering IV b/c can cause extravasation
