A nurse is taking orders from a provider for a client who is in cardiogenic shock. The provider has ordered norepinephrine to infuse at 30 mL/hr. The bag arrives from the pharmacy composed of 40 mg of norepinephrine contained in a 500 mL solution. Calculate how many mcg/minute the client receives.
a. 28
b. 20
c. 40
d. 46
c. 40
rationale: To calculate, the nurse first determines the amount of mg/hour:30 mL/hr (rate) X 40 mg (dose available) / 500 mL (volume) = 2.4 mg/hr. Then convert mg to mcg: 2.4 mg X 1000 = 2,400 mcg/hr. This amount is then converted from the total per hour to the total per minute: 2,400 mcg/hr/ 60 minutes = 40 mcg/minute. To see the Dimensional Analysis method, see the Rationale Image.
