A client is receiving one liter of DSW 0.45% normal saline IV every 8 hours by gravity infusion. The IV tubing has a drip factor of 12 gtt/mL. The nurse should regulate the IV to deliver how many drops per minute? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["25"]
Total volume: 1,000 mL
Time for infusion: 8 hours = 480 minutes
Drip rate: 1,000 mL ÷ 480 minutes = 2.08 mL/min
Drops per minute: 2.08 mL/min × 12 gtt/mL = 25 gtt/min

Correct Answer is ["83"]
Explanation
Total dose: 20 million units ÷ 10 million units/L = 2 L
Volume per hour: 2 L ÷ 24 hours = 0.083 L/hour = 83 mL/hour
Correct Answer is ["105"]
Explanation
Convert weight: 165 pounds ÷ 2.2 = 75 kg
Dose required: 2 mcg/kg/min × 75 kg = 150 mcg/min
Total mg/min: 150 mcg ÷ 1,000 = 0.15 mg/min
Infusion rate: 0.15 mg/min ÷ (50 mg/1,000 mL) = 105 mL/hour
