Step 1:: Convert the quantity of medication ordered from grams to milligrams.
We know that: 1 gram (g) = 1000 milligrams (mg) So,
Step 2:6 g = 0.6 * 1000 mg = 600 mg
Step 3:: Set up a proportion to find the volume (in milliliters) of the medication to be administered.
\frac{\text{concentration}}{1} = \frac{\text{ordered dose}}{\text{volume}}
The proportion is:
Step 4:: Plug in the given values into the proportion.
\frac{500 \text{ mg}}{5 \text{ ml}} = \frac{600 \text{ mg}}{\text{volume}}
We have:
Step 5:: Solve for the volume.
\text{volume} = \frac{3000}{500} \text{ ml}
Cross-multiply to get: Dividing both sides by 500 mg gives: Cancel the milligrams on the right-hand side: Perform the division:
Step 6:: Simplify the volume.
\text{volume} = 6 \text{ ml}
Dividing 3000 by 500 gives 6, so:
Final Answer
The nurse will give 6 ml of the medication.
