Question

1. how many ml of a 1.5% drug would a 25 lb dog receive, if the dose were 15 mg/kg?

Explanation:

Step1: Convert dog's weight to kg

1 lb = 0.453592 kg, so 25 lb = 25×0.453592 kg = 11.3398 kg

Step2: Calculate the total dose in mg

Dose is 15 mg/kg, so for a 11.3398 kg dog, total dose = 15×11.3398 mg = 170.097 mg

Step3: Determine the concentration of the drug in mg/mL

A 1.5% drug means 1.5 g (or 1500 mg) in 100 mL, so concentration = $\frac{1500}{100}$ mg/mL = 15 mg/mL

Step4: Calculate the volume in mL

Volume = $\frac{\text{Total dose in mg}}{\text{Concentration in mg/mL}}$, so volume = $\frac{170.097}{15}$ mL = 11.34 mL

Answer:

11.34 mL
