To calculate how much tramadol solution the patient needs, you can use the following formula:
1. **Determine the concentration of the solution**: You have a standard dose of 50 mg in 2 mL. To find the concentration per mL:
\[
\frac{50 \text{ mg}}{2 \text{ mL}} = 25 \text{ mg/mL}
\]
2. **Calculate the volume needed for 80 mg**: To find out how many mL you need to administer 80 mg, you can use the formula:
\[
\text{Volume (mL)} = \frac{\text{Desired Dose (mg)}}{\text{Concentration (mg/mL)}}
\]
\[
\text{Volume (mL)} = \frac{80 \text{ mg}}{25 \text{ mg/mL}} = 3.2 \text{ mL}
\]
So, the patient needs **3.2 mL** of the tramadol solution.
