Dоsаge Cаlculаtiоn Questiоns: INSTRUCTIONS: Calculate the following dosage problems and show your work on the scratch paper. You may use your calculator. INSTRUCTIONS FOR ROUNDING OFF NUMBERS: 1) Round off gtts / min to the nearest whole number. EXAMPLES: 16.7 gtts / min = 17 gtts / min OR 14.2 gtts / min = 14 gtts / min 2) Round off answers LESS than 1 to 2 decimal points (hundredths). EXAMPLES: 0.035 = 0.04 OR 0.201 = 0.20 3) Round off answers GREATER than 1 to 1 decimal point (tenths). EXAMPLES: 1.65 = 1.7 OR 1.23 = 1.2 4) Round off mL / hr to the nearest whole number. EXAMPLES: 1.4 mL / hr = 1 mL / hr OR 1.6 mL / hr = 2 mL / hr A 60 kg patient is receiving a dopamine infusion started at 3 mcg/kg/min. The provider orders to increase the rate by 5 mcg/kg/min every 15 minutes as needed to maintain SBP > 90. The dopamine is supplied as 400 mg in 250 mL.
