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.

Explanation
A. Sprinkle on warm food: Pancreatic enzyme replacement therapy should not be sprinkled on warm food, as heat can destroy the enzymes and reduce their effectiveness.
B. Take before meals: Pancrease (lipase, protease, amylase) is typically taken before meals or snacks to help with the digestion of food. It should be taken with food to assist in breaking down fats, proteins, and carbohydrates.
C. Take 1 hour after eating: Enzymes are most effective when taken before or during meals, not after.
D. Mix with juice: Mixing the medication with juice is not recommended because juices (especially acidic ones like orange juice) may alter the effectiveness of the enzymes.
