Answer:
To find out how many mg the patient will be taking each dose, you can use the following steps:
1. Identify the concentration of the suspension: 250 mg/5 mL
2. Identify the dose volume: 8 mL
3. Set up a proportion to relate the dose volume to the concentration:
(250 mg)/(5 mL) = (x mg)/(8 mL)
4. Cross-multiply and solve for x:
x = (250 mg) × (8 mL) / (5 mL)
x = 400 mg
So, the patient will be taking 400 mg each dose.

Answer:
400 mg per dose
Explanation:
Dosage calculations can be solved using the following formula:
ordered amount × dosage strength = amount to administer
The ordered amount is the written prescription given from the provider, typically a physician, to be administered to the patient. This is usually represented as a unit of mass (e.g. milligrams, mg) rather than a unit of volume (e.g. milliliters, mL). However, in this case, it is the opposite with the ordered amount being 8 mL.
The dosage strength is the concentration of medication available in stock via the pharmacy, given as a proportion of mass-to-volume (e.g. milligrams per milliliter, mg/mL) or mass-per-unit (e.g. 100mg tablet). In this question, the dosage strength is 250 mg/mL.
Now, plug these components into the formula.
8 mL × (250 mg / 5 mL) or 8 mL × [tex]\frac{250 mg}{5 mL}[/tex]
= (8 mL × 250 mg) ÷ 5 mL
= 2000 mL mg ÷ 5 mL
= 400 mL mg / mL
mL in both numerator and denominator cancel each other out, leaving mg as the remaining unit of measurement.
400 mg / 1
= 400 mg
The patient takes 400 mg of medication each dose.
