A medication is to infuse at 0.6 mg/hr. The solution available is 50 mg/150 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number & fill in the blank with the numerical value only)
The Correct Answer is ["2"]
Desired dose rate = 0.6 mg/hr
Available concentration = 50 mg / 150 mL
- Calculate the concentration in mg/mL:
Concentration (mg/mL) = 50 mg / 150 mL
= 1/3 mg/mL
- Calculate the flow rate in mL/hr:
Flow rate (mL/hr) = Desired dose rate (mg/hr) / Concentration (mg/mL)
= 0.6 mg/hr / (1/3 mg/mL)
= 0.6 × 3 mL/hr
Flow rate (mL/hr) = 1.8 mL/hr
- Round to the nearest whole number:
= 2 mL/hr
