cardiac medications digoxin (Lanoxin)
How does digoxin work?
What is the mechanism of action for ARBs (sartans)?
block type II angiotennin
vasodilator
What is the mechanism of action?
vasodilation by inhibiting formation of angiotensin II
breaks down bradykinin which increases bradykinin levels
contributes to bronchodilator
what are the contraindications of beta-blockers (prils)?
use cautiously in asthmatics, diabetes
What is the mechanism of action of calcium blockers (pine)?
decrease Ca
influx into vascular smooth muscle, resulting in vasodilation & lower bp
Before giving digoxin the nurse should check the?
AP for 1 full minute
What are the major side effects of ARBs (sartans)?
renal failure
hypotension
major side effects of ACE inhibitors (prils)
dry cough
angioedema
hypotension
What are the major side effects of calcium channel blockers (pine)?
HA
flushing
tachycardia
ankle swelling
gain hypertrophy
When can digoxin toxicity occur?
anytime
What are the nursing indications of ARBs (sartans)?
monitor BP
kidney function
What are the nursing considerations for ACE (prils) inhibitors?
pregnancy, bilateral renal stenosis
What are the nursing indications for calcium channel blockers (pine)?
monitor BP
HR
fluid volume
What is the antidote for digoxin toxicity?
What are the contraindications of ARBs (sartans)?
pregnancy, bilateral stenosis
What is the mechanism of action for beta-blockers (olol)?
counteracts epinepherine
reduces workload of heart
can decrease BP & HR
What are the contraindications of calcium channel blockers (pine)?
heart block
CHF
What are the major side effects of beta blockers (olol)?
hypotension
dizziness
fatigue
weakness
What should the nurse assess before giving antihypertensive medications?
BP, HR before the med is given
If BP < 90/60 or HR <60
call MD, hold drug until receive further instructions
