To solve the problem of calculating the correct dosage to administer, we need to determine how many milliliters (ml) to give based on the order and the concentration of the medication we have.
Here's the step-by-step process:
1. Identify the order:
- The order is 0.8 milligrams (mg).
2. Identify the concentration you have:
- We have a medication concentration of 4.0 milligrams per milliliter (mg/ml).
3. Set up the dosage formula:
- To determine the volume to administer, we use the formula:
[tex]\[
\text{Volume to give (ml)} = \frac{\text{Ordered dose (mg)}}{\text{Concentration (mg/ml)}}
\][/tex]
4. Plug in the values:
- Ordered dose = 0.8 mg
- Concentration = 4.0 mg/ml
5. Calculate:
- [tex]\[
\text{Volume to give (ml)} = \frac{0.8 \text{ mg}}{4.0 \text{ mg/ml}}
\][/tex]
- Performing the division:
[tex]\[
\frac{0.8}{4.0} = 0.2 \text{ ml}
\][/tex]
Therefore, the required dosage to give is 0.2 milliliter(s).
