Read each question carefully and show all your work. Use appropriate units for your answers. Round to two decimal places where necessary.
1. A medication is available in a powdered form. The label states that adding 5 mL of sterile water will yield a solution with a concentration of 250 mg/5 mL. If a patient requires a dose of 375 mg, how many milliliters of the reconstituted solution should be administered?
2. You have a stock solution of 10% dextrose. To prepare 500 mL of a 2.5% dextrose solution, you would need to add mL of the 10% stock solution to mL of diluent.
3. A vial contains 1 gram of a drug. The directions state to reconstitute with 4 mL of diluent to achieve a concentration of 200 mg/mL. What is the total volume of the reconstituted solution?
4 mL
5 mL
10 mL
20 mL
4. When reconstituting a medication, the amount of diluent added always equals the final volume of the solution.
True
False
5. A physician orders 15 mg of a drug for a patient. The drug is supplied in a vial containing 20 mg of powdered medication. The manufacturer's instructions state to reconstitute the vial with 5 mL of sterile water, which will result in a displacement volume of 0.5 mL. Calculate the concentration of the reconstituted solution and the volume to administer to the patient.
This graduated cylinder can be used to accurately measure diluent for reconstitution. Ensure you read the meniscus at eye level.
