tests with best solutions, Exams of Nursing
lidocaine - ANSWERTx v-tach, ventricular dysrythmia, MI, stabilizes cardiac
membrane
labetalol - ANSWERantihypertensive, decreases BP without significant
reduction in HR
esmolol - ANSWERbrings down BP and HR
epinephrine - ANSWERvasodilation and bronchodilation tx shock and cardiac
arrest
dopamine - ANSWERincreased cardiac output and vasodilation which raises
BP tx shock and hypotension
dobutamine - ANSWERcauses increased cardiac contractility without raising
HR
atropine - ANSWERincreases HR Tx bradycardia and decreases secretions
