taper dose over 7-14 days [2] Hypertension/angina: monitor ECG directly when giving IV during initial treatment [3] Monitor B/P during beginning treatment, periodically thereafter; pulse; note rate, rhythm, quality; check apical/radial pulse before administration; notify prescriber of any significant changes (pulse <40 bpm), if cardiac output is decreased, atropine may be needed; ECG q 5-15 min during and after use [4] Check for baselines in renal, liver function tests before therapy begins and periodically thereafter [5] Assess for edema in feet, legs daily;
