Answer:
The client will need 2 mL
Explanation:
This can be solved by a simple rule of three.
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.
In this problem, the measures are the number of millingrams of the medication and the number of mililiters. As the number of mg increases, so will the number of ml.
So, we have the following direct rule of three.
5 mg - 10 mL
1 mg - x mL
5x = 10
x = 2mL
The client will need 2 mL
