A nurse is preparing to administer medroxyprogesterone 150 mg IM to a client who has requested contraception. Available is medroxyprogesterone solution for injection 150 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1"]
Dosage (mL) = Ordered dose (mg) / Available dose (mg/mL) Therefore;
Dosage = 150 mg / 150 mg/mL Dosage = 1 mL
Therefore, the nurse should administer 1 mL of medroxyprogesterone solution for injection to the client.

Correct Answer is ["45"]
Explanation
Pump rate in mL/hour = Dose (mcg/kg/min) x Weight (kg) x 60 / Concentration (mcg/mL)
The concentration of nitroprusside is given as 50 mg in 250 mL of dextrose 5% in water.
Convert this to mcg/mL; multiply by 1000
Concentration (mcg/mL) = 50 mg x 1000 / 250 mL = 200 mcg/mL Therefore;
Pump rate in mL/hour = 2 mcg/kg/min x 75 kg x 60 / 200 mcg/mL Pump rate in mL/hour = 45 mL/hour
Therefore, the nurse should set the IV pump to deliver 45 mL/hour
Correct Answer is ["1.7"]
Explanation
The dose of dopamine in mg/hr: 5 mcg/kg/min x 4.4 kg x 60 min/hr = 1320 mcg/hr Converted to mg: 1320 mcg/hr / 1000 mcg/mg = 1.32 mg/hr
Infusion rate in mL/hr: 1.32 mg/hr / (200 mg/250 mL) = 1.65 mL/hr Rounded off to the nearest tenth: 1.7 mL/hr
