NUR 243 - WEEK 8 UPDATED ACTUAL
Questions and CORRECT Answers
Calcium Channel Blockers - CORRECT ANSWER -Block calcium ions from entering cells
Blocking causes vasodilation
decreased cardiac workload and force of contraction
Calcium Channel Blockers classification - CORRECT ANSWER -nondihydropyridines
dihydropyridines
Where do nondihydropyridines act? - CORRECT ANSWER -on the arterioles and the electrical
impulses on the heart
nondihydropyridines: MOA - CORRECT ANSWER -block arteries and arterioles of the heart
blocks SA nide
blocks AV node
blockade in the myocardium
nondihydropyridines: indications/uses - CORRECT ANSWER -angina pectoris; decreases
myocardial oxygen demand
essential hypertension; reduces vascular constriction
cardiac dysrhythmias; slows SA and AV node
Nondihydropyridines: adverse effects - CORRECT ANSWER -Bradycardia, AV block ,
hypotension, constipation, edema, dizziness/headache
Nondihydropyridines: interactions - CORRECT ANSWER -digoxin
beta-adrenergic blocking agents
grapefruit juice
, Where do dihydropyridines act? - CORRECT ANSWER -primarily on peripheral vessels
dihydropyridines: MOA - CORRECT ANSWER -blockade of calcium channels in peripheral
arterioles causing vasodilation
not used to treat dysrhythmias
no direct effect on conduction of heart (AV/SA node)
dihydropyridines: indication/uses - CORRECT ANSWER -angina pectoris
HTN
off label use: suppress preterm labor
dihydropyridines: adverse effects - CORRECT ANSWER -Peripheral edema, flushing, dizziness,
headache, reflux, tachycardia, hypotension
Vasodilatiors - CORRECT ANSWER -drugs that dilate blood vessels
can be produced by many drugs with variety of therapeutic applications
can act primarily in veins or arterioles or both
Drugs that dilate arterioles cause a decrease in _ ? - CORRECT ANSWER -cardiac afterload
Drugs that dilate veins reduce the force with which the blood return to the hearts causing a decrease in _ ?
- CORRECT ANSWER -cardiac preload
Vasodilators: indications/uses - CORRECT ANSWER -HTN
hypertensive crisis
angina pectoris
MI
PVD
Vasodilators: adverse effects - CORRECT ANSWER -postural hypotension
