When given docusate sodium (Colace) 0.3 grams, how many capsules are necessary if each capsule contains 100 mg?

To determine the correct number of capsules needed for a dose of docusate sodium (Colace) at 0.3 grams, it is important to convert grams to milligrams, as the contents of each capsule are specified in milligrams.

1 gram is equal to 1000 milligrams. Therefore, 0.3 grams is converted as follows:

0.3 grams × 1000 mg/g = 300 mg.

Next, each capsule contains 100 mg of docusate sodium. To find out how many capsules are needed to reach a total of 300 mg, divide the total required dosage by the dosage per capsule:

300 mg ÷ 100 mg/capsule = 3 capsules.

This calculation shows that 3 capsules are required to administer the full dosage of 0.3 grams of docusate sodium. Thus, the correct answer is that you would need 3 capsules to achieve the prescribed medication amount.
