The nurse has to withdraw to 5.8ml of heparin injection to administer a bolus dose 5800units.

Patients body weight:74kg

Dose:5mcg/kg/min

Drug concentration:200mcg of dopamin

Conversion 200mg in to mcg

That is 200000mcg of dopamin

Drug volume is 250ml

Calculating flow rate (ml/hr):

Dose× body weight × total volume × time in min

-----------------------------------------------------------

Amount of drug

=27.75ml/hr

Rounding off to nearest whole number,that is 28

Flow rate(ml/hr)=28ml/hr
