11. 10mL of sterile water for injection is added to a 1g vial of Mefoxin, giving a 10.5mL final volume. What is the concentration of the reconstituted powdered Mefoxin?

1g = 1000mg 1000mg/10.5mL = 95.2mg/mL 95.2mg/mL = answer More test answers on https://studyhippo.com/chapter-27-powdered-drug-preparations/

13. You add 23mL of sterile water for injection to a 3g vial of antibiotic that has a powder volume of 3mL. What is the concentration, in mg/mL, of the reconstituted drug?

FV = 23mL + 3mL = 26mL 3g = 3000mg 3000mg/26mL = 115.4mg/mL 115.4mg/mL = answer More test answers on https://studyhippo.com/chapter-27-powdered-drug-preparations/

3. The package directions for a medication instruct you to add 4.2mL sterile water for injection to 1g of dry powder to give a concentration of 200 mg/mL. What is the powder volume of the medication?

200mg/1mL = 1000mg/x (x)(200mg) = (1mL)(1000mg) x = 5mL = FV PV = FV – DA PV = 5mL – 4.2mL PV = 0.8mL = answer More test answers on https://studyhippo.com/chapter-27-powdered-drug-preparations/

7. You add 10mL of sterile water for injection to 1g of a drug that has a powder volume of 0.8mL. What is the concentration of the drug in mg/mL in the final solution.

FV = 10mL + 0.8mL = 10.8mL 1g = 1000mg 1000mg / 10.8mL = 92.6mg/mL 92.6mg/mL = answer More test answers on https://studyhippo.com/chapter-27-powdered-drug-preparations/

9. To prepare 3g of Unasyn, the package insert states to add 6.4mL of diluent. The concentration obtained is 375mg/mL. What is the powder volume of the Unasyn?

3g = 3000mg 375mg/1mL = 300mg/x x = 8mL = FV (x)(375mg) = (1mL)(300mg) PV = FV – DA PV = 8mL – 6.4mL = 1.6mL 1.6mL = PV More test answers on https://studyhippo.com/chapter-27-powdered-drug-preparations/

What is Volume?

Volume is a measure of the amount of space that an object occupies. It is measured in cubic units such as meters, liters, or gallons. Volume can also refer to the total capacity or quantity of something, such as water stored in a tank or air in a balloon. In mathematics and science, volume has many different uses and applications.In chemistry, volume can be used to determine the number of atoms present in any given substance by measuring its mass and density. This allows chemists to identify compounds and elements based on their atomic structure. In physics, volume is commonly used for calculations related to pressure, temperature, energy transfer, sound waves, light waves and more. In biology it is often used when studying cell division or organ function as well as other organisms’ physical characteristics like size and shape. In engineering fields such as architecture or manufacturing it’s important to accurately estimate volumes when designing buildings or planes so they will not exceed weight limitations (aircraft) or structural integrity requirements (buildings). Geologists use volume measurements when studying topographical features like mountainsides and valleys while meteorologists use them when discussing air masses since air masses have varying densities at various altitudes which affects weather patterns around the world. Finally, volume plays an important role in economics because economic output is typically measured with respect to production inputs including labor hours worked plus materials consumed multiplied by some unit measure for value added over time this calculation requires accurate determination of volumes associated with each component involved in production process (e.,g., raw material dimensions).
