What You'll Learn
Pharmacy Calculations is a critical topic for the PTCB (PTCE) exam, as it assesses the candidate's ability to perform essential mathematical calculations required in the pharmacy setting. This topic covers a range of calculations, including unit conversions, dosage calculations, concentration and dilution problems, and more. Mastering these skills is crucial for pharmacy technicians to ensure accurate medication dispensing, patient safety, and compliance with industry standards.
Key Concepts
Unit Conversions
The process of converting measurements from one unit to another, such as milligrams to grams or milliliters to liters. This is essential for accurately interpreting and applying medication instructions.
Dosage Calculations
Determining the appropriate amount of medication to be administered based on factors such as patient weight, desired therapeutic effect, and medication strength. This ensures patients receive the correct dose.
Concentration and Dilution
Calculating the concentration of a medication solution and the appropriate dilution factors to prepare the desired concentration. This is important for compounding and admixing medications.
Alligation
A technique used to determine the correct proportions of two or more ingredients to achieve a desired final concentration or composition.
Percentage Calculations
Calculating the percentage of a substance in a solution, which is commonly used in pharmacy settings for preparing and verifying the strength of medications.
Common Mistakes to Avoid
