Dosage calculations allow nurses to determine the appropriate dose of a medication for patients. Dosage calculations involve unit conversions, dosage by weight and volume over time.
Nurses are routinely required to verify correct medication dosage by calculations to ensure patients are receiving the correct dose. Dosage calculations are also required when medications are titrated or changed. Basic math skills are required to perform these calculations. Some medications are dosed based on patient weight, and nurses must perform a dosage calculation to determine the correct dose for a patient. Nursing students are given dosing competency exams. Several websites contain practice questions to prepare students for this exam.
