NCLEX-RN
Registered nurses must perform complex medication calculations involving intravenous drip rates, weight-based dosing for critical care infusions, and multi-step dimensional analysis problems. IV drip rate calculations require knowledge of the drop factor (gtt/mL) provided by the tubing set and the ordered infusion rate to determine drops per minute. Weight-based infusions such as dopamine (mcg/kg/min) and heparin (units/hr) demand precise patient weight measurement and continuous titration based on clinical response and laboratory values. Heparin titration protocols integrate bolus dose calculations with continuous drip adjustments guided by activated partial thromboplastin time (aPTT) results, requiring the nurse to recalculate doses at specified intervals.
