Question

your veterinarian is administering a sedative to your 40 pound dog bella. the sedative is mixed in saline solution. unfortunately the solution is pre - mixed at 2.5% for a horse and it needs to be a 0.5% concentration to be administered at 10 ml per pound for your dog. how much saline water needs to be added to the current solution to reduce the concentration to 0.5% and have the correct dosage for bella?

1. put the given information for the original solution by filling in the number of ml associated to 100 ml of original solution.

1. put the given information for the new solution by filling in the number of ml associated to 100 ml of new solution.

1. put in the number of ml to be administered per pound of bellas weight.

1. determine how many ml of new solution we will need to administer to bella.

1. next determine how much sedative will be in the amount from #4.

1. determine how many ml of original solution will contain the amount of sedative from #5.

1. finally determine how much saline water needs to be added to the current solution to reduce the concentration to 0.5% and have the correct dosage for bella.

Explanation:

1. Filling Original Solution Sedative (ml)

Step1: Calculate sedative in original solution

The original solution is 100 ml with 2.5% concentration. So sedative volume = \( 100 \times 0.025 = 2.5 \) ml.

Step1: Calculate sedative in new solution

The new solution is 100 ml with 0.5% concentration. So sedative volume = \( 100 \times 0.005 = 0.5 \) ml.

Step1: Extract the given dosage

The problem states it needs to be administered at 10 ml per pound.

Answer:

2.5

2. Filling New Solution Sedative (ml)
