Critical Care Medication ATI Questions and Answers | Latest Version | 2025/2026 | Correct & Verified A client weighing 70 kg is prescribed dopamine at 5 mcg/kg/min. The medication comes in a concentration of 400 mg in 250 mL. At what rate in mL/hr will you set the pump? Workings: 5 mcg × 70 kg = 350 mcg/min → 350 × 60 = 21,000 mcg/hr = 21 mg/hr 400 mg : 250 mL → 21 mg : X → X = (21×250)/400 = 13.125 mL/hr 13.1 mL/hr A 60 kg patient is receiving norepinephrine at 0.1 mcg/kg/min. The bag contains 8 mg in 250 mL. What is the infusion rate in mL/hr? Workings: 0.1 × 60 = 6 mcg/min → 6 × 60 = 360 mcg/hr = 0.36 mg/hr 8 mg : 250 mL → 0.36 mg : X → X = (0.36×250)/8 = 11.25 mL/hr 11.3 mL/hr You are to start a nitroglycerin drip at 10 mcg/min. The concentration is 50 mg in 250 mL. What is the rate in mL/hr? Workings: 50,000 mcg : 250 mL → 10 mcg : X → X = (10×250)/50,000 = 0.05 mL/min × 60 = 3 mL/hr 2 3 mL/hr A 55 kg client is to receive epinephrine at 0.05 mcg/kg/min. The solution is 4 mg in 250 mL. What is the infusion rate in mL/hr? Workings: 0.05 × 55 = 2.75 mcg/min → 2.75 × 60 = 165 mcg/hr 4 mg = 4,000 mcg → 4,000 mcg : 250 mL = 165 mcg : X → X = (165×250)/4000 = 10.31 mL/hr 10.3 mL/hr A client is ordered to receive a dobutamine drip at 8 mcg/kg/min. The patient weighs 80 kg. The IV bag contains 250 mg in 250 mL. What is the pump rate? Workings: 8 × 80 = 640 mcg/min → 640 × 60 = 38,400 mcg/hr = 38.4 mg/hr 250 mg : 250 mL = 38.4 mg : X → X = (38.4×250)/250 = 38.4 mL/hr 38.4 mL/hr A client is receiving a lidocaine infusion at 2 mg/min. The bag has 1 g in 250 mL. What is the infusion rate in mL/hr? Workings: 1 g = 1,000 mg → 1,000 mg : 250 mL = 2 mg : X → X = (2×250)/1,000 = 0.5 mL/min × 60 = 30 mL/hr 30 mL/hr 3 A 90 kg client needs dopamine at 3 mcg/kg/min. The bag contains 400 mg in 250 mL. What rate will you set? Workings: 3 × 90 = 270 mcg/min → 270 × 60 = 16,200 mcg/hr = 16.2 mg/hr 400 mg : 250 mL = 16.2 mg : X → X = (16.2×250)/400 = 10.125 mL/hr 10.1 mL/hr You need to start a vasopressin infusion at 0.03 units/min. The concentration is 20 units in 100 mL. What rate will you set in mL/hr? Workings: 20 units : 100 mL = 0.03 units : X → X = (0.03×100)/20 = 0.15 mL/min × 60 = 9 mL/hr 9 mL/hr The physician orders a nitroprusside infusion at 0.5 mcg/kg/min for a 60 kg patient. The concentration is 50 mg in 250 mL. What is the infusion rate? Workings: 0.5 × 60 = 30 mcg/min → 30 × 60 = 1,800 mcg/hr = 1.8 mg/hr 50 mg : 250 mL = 1.8 mg : X → X = (1.8×250)/50 = 9 mL/hr 9 mL/hr 4 A patient is to receive milrinone at 0.375 mcg/kg/min. The weight is 75 kg. The infusion contains 20 mg in 100 mL. What rate in mL/hr will you set? Workings: 0.375 × 75 = 28.125 mcg/min → 28.125 × 60 = 1,687.5 mcg/hr = 1.6875 mg/hr 20 mg : 100 mL = 1.6875 mg : X → X = (1.6875×100)/20 = 8.44 mL/hr 8.4 mL/hr You receive an order for amiodarone 1 mg/min for a client. The IV bag contains 150 mg in 100 mL. What is the rate in mL/hr?
