Order: Colace 25 mg PO PRN for constipation. Available: Colace 20mg/5ml. How much will the nurse give??
1.25ml
6.25ml
6.3mg
6 mg
The Correct Answer is B
A. 1.25ml: The dosage of 20mg/5ml means 1ml contains 4mg. To get 25mg, you need more than 1.25ml.
B. 6.25ml: Since 20 mg is in 5ml, to administer 25mg, you can use the following calculation:
25mg * 
= 6.25ml
C. 6.3mg: This is incorrect because the dosage needed is 25mg, not 6.3mg.
D. 6mg: The prescribed dose is 25mg, not 6mg.
