At what rate in militers per hour (mLhr) should the nurse set the infusion pump? Record your answer using a whole number. Answer (mL/hr) you answer t

Answer 1

Duration = 4 hours
client weight = 150lb
8.4% sodium bicarbonate in 1000 mL of D2W with 150 mEq (150 mmol)

2mEq (2 mmol)/kg of 8.4% sodium bicarbonate to be administered in 4 hours

1 lb = 0.453592 kg
150 lbs = 69.0389 kgs

Weight (kg) X Dosage Ordered = Y (Required Dosage)

69.0389 kgs X 2 mEq = 138 mEq

Desired dosage / Available dosage X Quantity = volume of medication in mL to be administered

(138 mEq / 150 mEq) X 1000 mL = 920 mL

Flow rate of Infusion Pump

Volume (mL) / Time (h) = Y (Flow Rate mL/h)

920 mL / 4hrs = 230 mL/hr

Answer 2

227 milliliters
