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.

Correct Answer is A
Explanation
A. Serum amylase: Serum amylase levels are typically elevated in cases of acute pancreatitis. Amylase is an enzyme produced by the pancreas, and an elevation indicates pancreatic inflammation or injury.
B. Serum bilirubin: While elevated bilirubin levels can indicate liver or biliary issues, they are not diagnostic for pancreatitis.
C. Serum calcium: Hypocalcemia (low calcium) can be seen in severe acute pancreatitis, but it is not a primary diagnostic indicator for the condition.
D. Serum lipids: Elevated serum lipids (especially triglycerides) can contribute to pancreatitis, but they are not diagnostic for it. Serum amylase and lipase are more specific to the diagnosis of pancreatitis.
