- adrenergic agonist
- inotropic
- vasopressor
2
Q
trade name
A
Inotropin
3
Q
Dopamine receptors are found in the ______.
A
kidneys
4
Q
action of dopamine at low dose
A
renal blood vessl dilation
5
Q
action of dopamine at moderate dose
A
- renal blood vessel dilation
- ↑ HR
- ↑ myocardial contractility
- ↑ rate of conduction through AV node
6
Q
action of dopamine at high dose
A
- renal blood vessel dilation
- ↑ HR
- ↑ rate of conduction through AV node
- ↑ myocardial contractility
- vasoconstriction
7
Q
receptors activated by low dose
A
dopamine (kidneys)
8
Q
receptors activated by moderate dose
A
- dopamine (kidneys)
- Beta 1 (heart)
9
Q
receptors activated by high dose
A
- dopamine (kidneys)
- Beta 1 (heart)
- Alpha 1 (blood vessels)
10
Q
use
A
- shock
- vasoconstriction → ↑ systolic BP
- HF
11
Q
AE and interventions
A
- Beta 1 activation can → dysrhythmias
- ↑ workload of heart, O2 demand → angina
- continuous cardiac monitoring
- monitor closely for
- dysrhythmia
- change in HR
- CP
- notify provider and Tx per protocol
- necrosis
- monitor IV site closely
- D/C infusion at first sign
- use central line if available
12
Q
contraindications
A
- tachydysrhythmias
- v-fib

Q
precautions
A
- pregnancy (C)
- hyperthyroidism
- angina
- Hx of MI
- HTN
- DM
14
Q
interactions
A
- alpha-blockers counteract vasoconstriction
- diuretics: promote beneficial effects
15
Q
admin
A
- continuous IV via pump
- titrate based on BP response
- stop if infiltration
- assess/monitor
- CP
- UOP
