Conversions and Dosage Calculations

These flashcards cover key conversions, dosage calculation formulas, and IV flow rates relevant for pharmacology and dosage assessment.

What is the volume conversion for 1 milligram (mg)?

1 mg = 1,000 micrograms (mcg)

How many grams are in a kilogram?

1 kg = 1,000 grams (g)

What is the volume equivalence for 1 ounce (oz)?

1 oz = 30 milliliters (mL)

How many tablespoons are in 1 cup?

8 oz = 1 cup is equivalent to 16 tablespoons (as 1 tbsp = 15 mL and 1 cup = 240 mL).

What is the conversion between liters and milliliters?

1 L = 1,000 mL

What is the dosage calculation formula?

(Desired / Have) x Volume = Amount

What should you remember about leading and trailing zeros in dosages?

Use leading zeros (0.2 not .2) and no trailing zeros (1 not 1.0).

Convert 150 mg ordered with 300 mg available per tablet to tablets.

0.5 tab (150 mg / 300 mg/tab = 0.5 tab).

Calculate the IV flow rate for 1000 mL over 3 hours.

333 mL/hr (1000 mL / 3 hr = 333 mL/hr).

What is the formula to calculate gtt/min for IV drop rates?

(mL x Drop factor) / Minutes = gtt/min.
