A nurse is preparing to administer a 100 mcg stat dose of fentanyl IV for a client with severe pain. The amount available is 0.05 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 ["2"]
Convert micrograms (mcg) to milligrams (mg):
100 mcg=0.1 mg
Determine the concentration available:
0.05 mg/mL
Use the formula to calculate the volume:
Volume (mL)=Required dose (mg)/Concentration (mg/mL)
Volume (mL)=0.1 mg/0.05 mg/mL
Calculate the volume:
Volume (mL)=2
