Flashcards in Antidysrhythmics Deck (32):
1

Procainamide hydrochloride trade name

procainamide

2

procainamide hydrochloride class

antidysrhythmic

3

procainamide hydrochloride expected effect

depress excitability of cardiac muscle to electrical stimulation and slows conduction in atrium, bundle of His, increases refractory period.

Sodium channel blocker, slowing conduction sodium ions thru sodium channels. Blocking these channels slows conductivity & prolongs action potential & refractory period. Result is decrease excitability and impulse conduction of atria & ventricles

4

why use procainamide hydrochloride

ventricular dysrhythmia

5

procainamide hydrochloride dose

20-50mg/min (17mg/kg)

6

procainamide hydrochloride route admin

IV, IM

7

procainamide hydrochloride adverse effects

skin sores, hives, fever, chills
- heart block, circa collapse, angioedema, tornadoes de points, agranulocytosis

8

procainamide hydrochloride nursing implications

- use ECG to check PR-QRS segments
- blood levels & CBC
- vitals
- respiratory status (rate, rhythm, crackles)
- toxicity (confusion, nausea, vomit, drowsy)
- CNS effects (dizzy, confused, seizure)

9

propanolol trade names

inderal, inderal LA, Innopran

10

propranolol expected effect

non selective beta blockers with negative inotropic, chronotropic, dromotropic properties

11

why use propanolol

angina, hypertension, dysrhythmias, migraine, cyanotic spells from aortic stenosis, MI

12

dosage of propanolol

PO: 10-30mg tid qid, IV 1-3mg give 1mg/min may report after 2 mins & q4h intervals

13

propanolol routes admin

PO, IV

14

propanolol adverse effects

bradycardia, CHF, pulmonary edema, dysrhythmias, thrombocytopenia, Stevens Johnson syndrome, toxic epidermal necrolysis

15

propanolol nursing implications

- no abrupt discontinuation
- monitor with ECG
- note angina pain (duration, time started)
- fluid overload (edema)
- tolerance
- headache, light head, low BP= lower dose

16

adenosine trade name

adenocard

17

adenosine drug classes

antidysrhythmic, endogenous nucleoside

18

adenosine expected effect

slow conduction thru AV node, interrupt re-entry pathways into AV node & restore normal sinus rhythm in patients with tachycardia, hypoxia

19

why use adenosine

PSVT, MI, CAD, Wolff Parkinson white syndrome

20

adenosine route admin

IV

21

adenosine doses

IV bol 6mg, if sinus rhythm not return to normal give 12mg by IV BOL> may repeat 12mg dose

22

adenosine adverse effects

atrial tachydysrhythmias, AV block, cardiac arrest, atrial, bronchospasms

23

adenosine nursing implications

cardiopulmonary status: BP, pulse, respiration, rhythm, ECG intervals, dysrhythmias
respiratory status: rate, rhythm, lung fields, crackles

24

amiodarone trade names

cordarine, pacerone, nexterone

25

amiodarone drug classes

antidysrhythmic, iodinated benzofuran derivative

26

amiodarone expected effect

prolong action potential & refractory period, beta & alpha blocker, increase PR QT intervals, decrease sinus rate, peripheral vascular resistance

27

why use amiodarone

ventricular tachycardia, ventricular fibrillation, supraventircular dysrhythmias

28

amiodarone routes of admin

PO, IV

29

amiodarone adverse effects

sinus arrest, CHF, SA node dysfunction, AV block, hepatotoxcitiy, pulmonary toxcitiy

30

amiodarone nursing implications

assess: electroylytes, CNS, cardiac, resp
teach: no grape juice,do not discontinue abruptly

31

amiodarone black box

pulmonary toxicity, monitor with ECG

32

amiodarine doses

ventricular dysrhythmias
PO 800-1600mg/day for 1-3wk, then 600-800mg/dayfor 1 mo, IV is 150mg for 10mins then slow 360mg 6h
supraventricular dysrhythmias
PO 1.2-1.8g/ day until 10g, then 200-400mg/day,
IV 5-7mg/kg for 30-60min, then 1.2-1.8g in IV
