Powder Reconstitution (1 of 2) Required when medication is unstable over long periods of time in its liquid form. Must be performed before administration using a sterile diluent. Read information and directions on drug label carefully. Identify the type of diluent, amount of diluent, and route of administration. Note the drug strength or concentration after reconstitution. What are some common sterile diluents? Common sterile diluents include water, normal saline solution, and 5% dextrose solution. What should you do if no directions are available with the medication? Consult the Physicians’ Desk Reference (PDR), hospital drug formulary, pharmacology text, or hospital pharmacy. Copyright © 2020 by Mosby, an imprint of Elsevier Inc. All rights reserved.

Powder Reconstitution (2 of 2) Note the length of time that medication is usable after reconstitution. Note the directions for storage of reconstituted medication. Place on drug label after reconstituting: Your initials Date and time of preparation Date and time of expiration Will the total reconstitution amount always be equal to the amount of diluent added? No, it will not. Sometimes the total reconstituted amount can be greater than the amount of diluent added. Copyright © 2020 by Mosby, an imprint of Elsevier Inc. All rights reserved.

Calculating Dosages Reconstitute medication. Solve dosage problems using dimensional analysis, proportion method, or alternate formula method. The known strength is determined by amount of diluent added to the medication. Copyright © 2020 by Mosby, an imprint of Elsevier Inc. All rights reserved.
