Question

a cat weights 4 kg and needs oral drop treatment. the dose is 20 mg/kg/day and the drops are equal to 25 mg/ml. how many ml should the cat get

Answer 1

To determine how many milliliters (ml) of the medication the cat should receive, we can follow these steps:

1. **Calculate the total daily dose needed for the cat:**
\[
\text{Total daily dose (mg)} = \text{Weight (kg)} \times \text{Dose (mg/kg/day)}
\]
\[
\text{Total daily dose} = 4 \, \text{kg} \times 20 \, \text{mg/kg/day} = 80 \, \text{mg/day}
\]

2. **Convert the daily dose from mg to ml using the concentration of the drops:**
The concentration of the drops is 25 mg/ml. To find the volume in ml, use the formula:
\[
\text{Volume (ml)} = \frac{\text{Total daily dose (mg)}}{\text{Concentration (mg/ml)}}
\]
\[
\text{Volume} = \frac{80 \, \text{mg}}{25 \, \text{mg/ml}} = 3.2 \, \text{ml}
\]

So, the cat should receive **3.2 ml** of the medication each day.
