Final answer:
To calculate the correct dosage of Colace 100mg liquid when the concentration is 20mg/5ml, you use a simple proportion calculation. You will administer 25 ml per dose to deliver the correct 100mg dose of Colace.
Step-by-step explanation:
The question involves a medication dosage calculation, which is a common type of math problem encountered in the health and medicine fields. To determine how many milliliters of Colace (a stool softener) at a concentration of 20mg/5ml needs to be administered to give a dose of 100mg, you use the formula:
Dose ordered / Dose on hand = Volume on hand
In this case, the dose ordered is 100mg and the dose on hand is 20mg per 5ml. So the equation would be:
100mg / 20mg = x ml / 5 ml
To solve for x, we cross-multiply and divide:
100mg * 5ml = 20mg * x ml
500ml / 20mg = x ml
x = 25 ml
Thus, you will give 25 ml of Colace liquid for each dose.
