The amount of dobutamine dose that will you administer is 21ml/hr.

What do you mean by Dobutamine?

Dobutamine may be defined as a type of medication that will be administered during the treatment of cardiogenic shock and severe heart failure. It is majorly given intravenously (IV).

According to the question, amount of dobutamine given intravenously = 4 mcg/kg/min IV

Now, Converting mcg to mg:

4 micrograms ÷ 1000 =0.004 mg

Then, the weight of patient = 198 lb

Converting lb into kg = 198 ÷ 2.205 = 89.81 kg

∴ Total ordered dose = 0.004 × 89.81 = 0.35mg/min

Amount of dobutamine in a bag = 250 mg/250 ml

Converting mg into ml 250 mg = 250 ml

0.35 mg = x

x = 0.35 ml

The amount of dose given in per min = 0.35/ml/min.

Now, to calculate the dose in ml/hr

Rate (ml/hr) = Total dose × drop factor ÷ time in hr

= 0.35 × 60 = 21ml/hr.

Therefore, the amount of dose that will you administer is 21ml/hr.
