You will administer 0.93 mL of Heparin per dose to the patient weighing 93 kg, following the doctor's prescription of 50 units/kg/dose.

To find out how many millilitres (mL) of Heparin you need to administer for one dose, follow these steps:

1. Calculate the total dose of Heparin needed for the patient based on their weight and the prescribed dose:

[tex]\[ \text{Total dose} = \text{Heparin dose per kg} \times \text{Patient's weight} \][/tex]

[tex]\[ \text{Total dose} = 50 \, \text{units/kg/dose} \times 93 \, \text{kg} \][/tex]

[tex]\[ \text{Total dose} = 4650 \, \text{units} \][/tex]

2. Now, divide the total dose by the concentration of Heparin in the vial:

[tex]\[ \text{Volume (mL)} = \frac{\text{Total dose (units)}}{\text{Heparin concentration (units/mL)}} \][/tex]

[tex]\[ \text{Volume (mL)} = \frac{4650 \, \text{units}}{5000 \, \text{units/mL}} \][/tex]

[tex]\[ \text{Volume (mL)} = 0.93 \, \text{mL} \][/tex]

So, you will administer 0.93 mL of Heparin for each dose.
