A nurse is preparing to administer codeine 15 mg PO every 6 hr PRN pain. Available is codeine cral solution 10mg/5 ml. How many ml should the nurse administer per dose? (Round the answer to the nearest tenth Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["7.5"]
Calculations:
Desired dose = 15 mg
Concentration = 10 mg/5 mL
Volume = Desired dose / Concentration = 15 mg / (10 mg/5 mL) = 7.5 mL
The nurse should administer 7.5 mL of codeine.

Correct Answer is ["8"]
Explanation
Understanding the problem
We need to administer 2g of nafcillin.
The reconstituted solution has a concentration of 250 mg/mL.
We need to determine the volume to administer.
Step-by-step calculation
Convert grams to milligrams:
2 g = 2000 mg
Use the formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL) = 2000 mg / 250 mg/mL
Calculate the volume:
Volume (mL) = 8 mL
Therefore, the nurse should administer 8 mL of the reconstituted nafcillin solution.
Correct Answer is ["1880"]
Explanation
Understanding the problem
We need to calculate the total fluid intake in mL.
We have various fluids in ounces and mL.
There is a continuous IV infusion at 50 mL/hr for 12 hours.
Step-by-step calculation
Convert ounces to milliliters:
1 oz = 30 mL
Orange juice (½ cup):
½ cup = 4 oz → 4 oz = 120 mL
Milk:
8 oz = 240 mL
Coffee:
6 oz x 30 mL/oz = 180 mL
Ice chips:
4 oz x 1/2 x 30 mL/oz = 60 mL
Gelatin:
6 oz x 30 mL/oz = 180 mL
Decaffeinated coffee:
6 oz x 30 mL/oz = 180 mL
Apple juice:
4 oz x 30 mL/oz = 120 mL
Water: 200 mL
Calculate total oral fluid intake:
Calculate IV fluid intake:
IV fluid intake = 50 mL/hr x 12 hours = 600 mL
Calculate total fluid intake:
Therefore, the client's total fluid intake for the 12-hour shift is 1880 mL.
