Question

What is the dose range in mg and mL for a 13-kg dog for atropine sulfate (0.5mg/mL) at a dosage of 0.02 to 0.04mg/kg?

A) 0.26 to 0.52 mg; 0.52 to 1.04 mL
B) 0.26 to 0.52 mg; 0.26 to 0.52 mL
C) 0.65 to 1.3 mg; 1.3 to 2.6 mL
D) 0.65 to 1.3 mg; 0.65 to 1.3 mL

Answer 1

The correct dose range for atropine sulfate for a 13-kg dog at a dosage of 0.02 to 0.04mg/kg is 0.26 to 0.52 mg, which corresponds to 0.52 to 1.04 mL when converted using the concentration of the solution.

Step-by-step explanation:

The dosage range for a 13-kg dog for atropine sulfate at a dosage of 0.02 to 0.04mg/kg can be calculated as follows:

1. First, calculate the minimum dosage by multiplying the lowest end of the dosage range (0.02 mg/kg) by the weight of the dog (13 kg):
   0.02 mg/kg x 13 kg = 0.26 mg.
2. Next, calculate the maximum dosage using the higher end of the dosage range (0.04 mg/kg) by the weight of the dog (13 kg):
   0.04 mg/kg x 13 kg = 0.52 mg.
3. Convert these mg dosages to mL using the concentration of the atropine sulfate solution, which is 0.5 mg/mL. For minimum dosage:
   0.26 mg ÷ 0.5 mg/mL = 0.52 mL, and for maximum dosage:
   0.52 mg ÷ 0.5 mg/mL = 1.04 mL.

Hence, the dose range in mg is 0.26 to 0.52 mg, and in mL it is 0.52 to 1.04 mL, making option A the correct answer.
