NUR 521 Exam 2 Questions with Correct Answers Verified by Experts| Latest Update
Nifedipine MOA Moa- blocks calcium channels in VSM, very little blockage in the heart
Nifedipine contraindication IR dose is associated with increased mortality in MI and unstable
angina
Nifedipine preferred preferred in patients with AV block, HF, bradycardia, sick sinus
syndrome
Nifedipine uses HTN, angina, cannot be used to treat dysrhythmias
Nifedipine adverse effects peripheral edema (can be reduced with a diuretic), chronic rash,
reflex tachycardia (can be suppressed with a B bliocker)
Hydralazine MOA dilates arterioles to decrease peripheral resistance and blood pressure
Hydralazine uses Used to treat HTN, Hypertensive crisis, HF
Hydralazine usually requires usually requires the use of B blocker to prevent reflex
tachycardia
Hydralazine education Patient Education:
•Fall Risk
•Teach about s/s hypotension (dizziness, fatigue)
•Avoid standing up quickly
Digoxin MOA MOA:
•Positive inotropic action
,•Increase myocardial contractile force à increase CO
•Alter electrical activity of the heart (neurohormonal)
•Reduces s/s of CHF, but does not prolong life (second line agent)
Digoxin Lanoxin
Digoxin Use Use:
•Dysrhythmia (A. Fib or flutter)
•CHF
Digoxin Toxicity symptoms altered heart rate or rhythm, visual or gastrointestinal
disturbances
Digoxin levels •levels (0.5 to 0.8 ng/mL
Digoxin most serious adverse effect dysrhythmia, stop taking, may need antiarrhythmic or
antidote
Antidote for digoxin Digibind
Monitor with digoxin digoxin levels, potassium levels
Metoprolol adverse effects Adverse Effects:
•Bradycardia
•Fatigue, insomnia
•Masks hypoglycemia
•Decreased libido
, Metoprolol BBW BBW- do not stop abruptly due to angina and possible MI
Propranolol other name Inderal
Propranolol MOA MOA:
•Blocks both B1 (heart) and B2 (lung) adrenergic receptors
•Decreased automaticity of SA node, decreased conduction through AV node, decreased
myocardial contractility
•
Propranolol contraindications Contraindications:
•should be used cautiously in patients with asthma and is contraindicated in patients with sinus
bradycardia, high-degree heart block, and HF.
Propranolol uses Use:
•Angina
•Treating dysrhythmias (sinus tach, severe recurrent VT, exercise-induced tachydysrhythmias,
PAT
•HTN
•Tremor
Amiodarone MOA MOA •Delays repolarization, prolonging action potential
Amiodarone Contraindications Contraindications:
• 2nd and 3rd degree heart block
•Sick sinus syndrome
