Calculation
A nurse is preparing to administer esomeprazole 20 mg IV bolus in 100 mL 5% dextrose in water for a client who has peptic ulcer disease. Available is esomeprazole 40 mg/5 mL. How many milliliters should the nurse add to the 5% dextrose in water? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
Calculation: Desired dose = 20 mg. Available concentration = 40 mg / 5 mL = 8 mg/mL. Calculate the volume to administer in milliliters (mL). Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL) = 20 mg / 8 mg/mL = 2.5 mL.
