Sample questions from Text Out RN Protored 2026 Dosage Calculations

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

1. 1.The provider prescribes 750 mg of an oral medication. The supply is 250 mg per tablet. How many tablets should the nurse administer?

   • A.2.5 tablets
   • B.3 tablets
   • C.3.5 tablets
   • D.2 tablets

   Rationale: Divide the prescribed dose, 750 mg, by the available dose, 250 mg per tablet, to obtain 3 tablets. Two tablets provide only 500 mg, while 2.5 and 3.5 tablets provide doses above the prescription. For oral solid medications, calculate the number of units from the dose on hand.

2. 2.In the emergency department, the provider prescribes 1,000 mL of normal saline over 8 hours. What rate should the nurse program on the infusion pump?

   • A.150 mL/hr
   • B.800 mL/hr
   • C.125 mL/hr
   • D.100 mL/hr

   Rationale: Divide the total volume, 1,000 mL, by 8 hours to calculate 125 mL/hr. A rate of 100 mL/hr would deliver only 800 mL in 8 hours, and 150 mL/hr would deliver too much. The 800 mL/hr option confuses total volume with hourly rate.

3. 3.The provider prescribes a medication dose of 0.4 mg. The vial is labeled 1 mg/mL. Which actions or calculations are appropriate before administration? Select all that apply.

   • A.Confirm the prescribed dose and route against the medication record.
   • B.Calculate that the dose volume is 0.4 mL.
   • C.Verify that the medication concentration is 1 mg in each mL.
   • D.Draw up 4 mL because 0.4 mg is less than 1 mg.
   • E.Convert the dose to 400 mg before measuring.

   Rationale: The volume is 0.4 mL because 0.4 mg divided by 1 mg/mL equals 0.4 mL, and the concentration must be read accurately. Checking the prescription and route is an appropriate medication-safety step. Drawing up 4 mL would give 4 mg, and 0.4 mg equals 400 mcg, not 400 mg.

4. 4.A client is prescribed 500 mg of an antibiotic every 6 hours. How many milligrams should the nurse expect the client to receive in 24 hours?

   • A.2,000 mg
   • B.1,500 mg
   • C.3,000 mg
   • D.1,000 mg

5. 5.During medication preparation, the provider's order reads 0.25 g orally, and the tablets are labeled 125 mg each. How many tablets should the nurse prepare?

   • B.1 tablet
   • C.0.5 tablet
   • D.2 tablets
