practice problems - reconstitution calculations

PDF · 4 Feb 2026

This document is an educational resource for nursing students and licensed nurses that presents ten practice problems focused on medication reconstitution and dilution calculations. Each problem describes a clinical scenario (patient condition, ordered dose, and drug vial specifications) and asks the nurse to determine the volume of medication to draw or administer after reconstituting the drug. The document provides step‑by‑step worked solutions that include unit conversions (mg↔g, g↔mL), application of concentration formulas, and final volume results. Drugs covered include ceftriaxone (Rocephin), ampicillin, acyclovir, and vancomycin, with varying vial strengths and required dilutions. A legal disclaimer at the beginning emphasizes that the material is for learning only and not for clinical decision‑making. The tone is instructional and supportive, aiming to reinforce dosage‑calculation skills needed for safe medication administration.
