How many teaspoons of acetaminophen liquid suspension should parents administer for a dose of 300mg if the suspension provides 120mg/5mL?

To determine the appropriate dosage of acetaminophen liquid suspension for a dose of 300mg, you first need to understand the concentration of the suspension, which is 120mg per 5mL. To find out how much liquid is needed to provide a dose of 300mg, you can set up a proportion based on the concentration.

1. Calculate the amount of suspension needed for 300mg:
   • The formula to calculate the volume (in milliliters) needed to achieve the desired dose is derived from the concentration:

[ \text{Volume (mL)} = \frac{\text{Desired Dose (mg)}}{\text{Concentration (mg/mL)}} ] 2. Convert the concentration:

• Since the suspension provides 120mg for 5mL, to find the concentration in mg/mL, you divide 120mg by 5mL, yielding 24mg/mL.

3. Substituting into the formula: [ \text{Volume (mL)} = \frac{300mg}{24mg/mL} = 12.5mL ]

4. **Convert millilit
