Pharmacology Math Flashcards

• Dosage Calculation: When calculating medication dosages, conversions are essential. Example: For 230 mg from a stock of 600 mg/3 mL, the required dosage is 1.2 mL.

• Unit Conversion: 2.3 meters converts to 2300 millimeters.

• Tablet Dosing: Ordering 1100 mg of a medication from a stock of 275 mg tablets results in needing 4 tablets, not 0.25 of a tablet.

• Weight Conversion: Convert 63.2 kg to pounds results in 139 lb, not 139.1 lb as it rounds to the nearest whole number.

• Pounds to Ounces: 0.8 lb is equivalent to 12.8 oz.

• Pounds to Ounces Calculation: For 0.72 lb, it converts to approximately 11.5 oz.

• Kilograms to Grams: 32 kg is equivalent to 32000 grams.

• Roman Numerals: The numeral vii equals 7.

• Liquid Dosage Calculation: Ordering 450 mg from a stock concentration of 780 mg/2 mL equates to a required dose of 1.2 mL.

• Ounce Conversion Confirmation: 0.84 lb correctly converts to 13.4 oz.

• Kilogram to Pound Conversion: 52.1 kg is equal to 114.6 lb.

• Medication Batch Identification: The lot number indicates the specific batch of medication.

• Dosage Based on Weight: For a patient weighing 54 lb and requiring 0.7 mg/kg, the dose calculates to approximately 1.7 mL.

• Ounce Conversion Error: 8 oz actually equals 48 teaspoons.

• Brand vs. Generic Name: The brand name is the manufacturer's name for a drug.

• Milliliters to Liters: 597 mL converts to 0.597 L.

• Teaspoon to Milliliters: 10 teaspoons equals 50 mL.

• Celsius to Fahrenheit: 66.5°C converts to approximately 151.7°F.

• Proper Abbreviation Format: The correct way to write 2 milliliters is 2 mL, adhering to abbreviation rules.

• Tablet Dosing Calculation: Ordering 175 mg from a stock of 700 mg results in a dose of 0.25 tablet.

• Fahrenheit to Celsius Conversion: 54.4°C converts to approximately 129.9°F.

• Fahrenheit to Celsius Calculation: 99.4°F converts to 37.4°C.

• Fahrenheit to Celsius Confirmation: 74.4°F converts to approximately 23.6°C.

• Total Tablets Calculation: For a prescription of XYZ medication, 6 tabs tid for 16 days yields 288 tablets dispensed.

• Total Tablets Correction: A prescription of XYZ medication for 3 tabs qid over 10 days actually yields 120 tablets.

• Medication Volume Calculation: A patient's weight of 63 lb requiring 0.5 mg/kg from a stock of 25 mg/2 mL results in a volume of approximately 1.1 mL.

• Medication Volume Calculation Error: For a weight of 38 lb and a requirement of 1.2 mg/kg, the required volume is approximately 1.4 mL.

• Tablet Dosing Calculation: Ordering 150 mg from a stock of 600 mg results in a required dose of 0.25 tablet.

• Tablet Dosing Confirmation: A dose of 225 mg from a stock of 450 mg results in 0.5 tablet.

• Liquid Volume Calculation: For a stock concentration of 725 mg/mL, a required dosage of 500 mg equates to 0.7 mL.
