Sample questions from Clinical Dosage Calculationnurs Final Exam 2026

This material has 90 questions with answers and rationales. Here are the first 5.

1. 1.A medication order is for 0.25 g. The supply label is in milligrams. Which dose is equivalent?

   • A.250 mg
   • B.2,500 mg
   • C.0.025 mg
   • D.25 mg

   Rationale: One gram equals 1,000 mg, so 0.25 g equals 250 mg. The other values reflect multiplying or dividing by the wrong factor. Convert the units before comparing an order with a supply label.

2. 2.A home-care aide asks how to interpret common household-to-metric equivalents used in medication calculations. Which equivalents are correct? Select all that apply.

   • A.1 teaspoon = 5 mL
   • B.1 teaspoon = 15 mL
   • C.1 cup = 120 mL
   • D.1 tablespoon = 15 mL
   • E.1 fluid ounce = 30 mL

   Rationale: A teaspoon is 5 mL, a tablespoon is 15 mL, and a fluid ounce is approximately 30 mL. A cup is approximately 240 mL, not 120 mL, and 15 mL is a tablespoon rather than a teaspoon. Use the stated conversion standard when one is supplied in a problem.

3. 3.Which notation expresses a dose of five milligrams using safe decimal notation?

   • A.5.0 mg
   • B..5 mg
   • C.5 mg
   • D.0.50 mg

   Rationale: Writing 5 mg avoids a trailing zero that could be misread as 50 mg. A leading zero is required for values less than one, so .5 mg is unsafe and is also a different dose. The forms 5.0 mg and 0.50 mg unnecessarily include trailing zeros and represent different values.

4. 4.A provider prescribes 0.75 g of an oral medication. Which statements about the conversion and dose are correct? Select all that apply.

   • A.0.75 g equals 75 mg.
   • B.0.75 g equals 7,500 mg.
   • C.With 250-mg tablets, the dose is 3 tablets.
   • D.With 500-mg tablets, the dose is 1.5 tablets.
   • E.0.75 g equals 750 mg.
