Answer:
5 ml
Step-by-step explanation:
Given:
- 100 mg of medication per 20 ml of liquid
- 25 mg of medication needed by patient
Let x = amount of liquid needed in ml
To find the value of x, set up a ratio of medication to liquid:
⇒ 100 mg : 20 ml = 25 mg : x ml
⇒ 100/20 = 25/x
⇒ 5 = 25/x
⇒ 5x = 25
⇒ 5x ÷ 5 = 25 ÷ 5
⇒ x = 5
Therefore, the correct dose is 5 ml
