adrenergic agonist drugs
MOA
activates alpha + beta receptors
[+] ino and chrono
adrenergic agonist drugs
Tx
HF, shock states, hypotension, anaphylaxis
adrenergic agonist drugs
AE
hypertensive crisis tachy incr o2 demand necrosis extracasation
adrenergic agonist drugs
RN teaching
monitor for angina, extravasation (SQphentolamine is alpha blocker)
IM: 1:1k
IV: 1:10k
epipen is for allergies
antidysrhythmic medication classes

RN teaching
report butterfly shaped rash on face
K channel blocker drugs
amiodarone + sotalol
amiodarone + sotalol [K chnnl block]
Tx
- convert Afib
- any refractory arrythmia
amiodarone + sotalol [K chnnl block]
RN teaching
- photosensitivity
- monitor for visual changes: corneal verticillata
-long half life- remains in body for up to 2 mo
Ca channel blocker drugs
cerapamil, diltiazem
*the only 2 Ca channel blocks that treat dysrhythmias
cerapamil, diltiazem [Ca chnnl block]
MOA
[-] inotropic, chronotropic, dromotropic
cerapamil, diltiazem [Ca chnnl block]
RN teaching
- notify MD for HR<50
- if IV, monitor ECG
- supine for 1 hr after IV
- avoid grapefruit juice
- Change pt slowly
- notify MD for peripheral edema, chest pain or SOB
adenosine
RN teaching
- monitok EKG
- short half life: 10 seconds so AE’s <1min
- IVP fast- flush thru, undiluted, 6/12
- warn pt this will feel weird… asystole on monitor
- D is for DOWN
