Sample questions from ATI Nurs Dossage Calculation Final Exam 2026

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

1. 1.At change of shift on a medical-surgical unit, a 68-year-old client receiving an IV antibiotic has an order for 750 mg. The medication is supplied as 1 g in 10 mL. How many mL should the nurse administer?

   • A.75 mL
   • B.0.75 mL
   • C.7.5 mL
   • D.13.3 mL

   Rationale: The concentration is 100 mg/mL, so 750 mg requires 7.5 mL. The other volumes do not deliver the prescribed dose. Convert the available concentration to a dose per mL before calculating the volume.

2. 2.During a home-infusion visit, a 54-year-old client has an order for 1,200 mL of IV fluid over 10 hours using tubing with a drop factor of 15 gtt/mL. Which actions or calculations are appropriate? Select all that apply.

   • A.Recalculate the rate as 120 gtt/min.
   • B.Set the pump to 30 mL/hr.
   • C.Verify the tubing drop factor before calculating a manual rate.
   • D.If regulating manually, run the infusion at 30 gtt/min.
   • E.Set the pump to 120 mL/hr if an infusion pump is used.

   Rationale: Dividing 1,200 mL by 10 hours gives 120 mL/hr. The manual rate is 120 mL/hr x 15 gtt/mL divided by 60 min/hr, or 30 gtt/min, and the drop factor must be verified. A pump rate of 30 mL/hr is too slow, while 120 gtt/min is four times the calculated manual rate.

3. 3.A charge nurse on a rehabilitation unit is delegating care for a stable 76-year-old client who needs a routine oral temperature and assistance with breakfast. Which task is appropriate to delegate to an assistive personnel?

   • A.Assess the client's swallowing before breakfast.
   • B.Teach the client how to use a walker.
   • C.Evaluate the client's response to a new analgesic.
   • D.Obtain and report the routine temperature.

   Rationale: Obtaining a routine temperature for a stable client is an appropriate task to delegate, with the result reported to the nurse. Swallowing assessment, teaching, and evaluation of medication response require nursing judgment. Delegation does not transfer the nurse's responsibility to follow up on reported findings.

4. 4.Refer to the client's chart. Which action should the nurse take first regarding the infusion?

   • A.Stop the infusion and notify the provider of the changing assessment.
   • B.Increase the infusion rate to finish the prescribed volume sooner.
   • C.Continue the infusion and reassess at 1200.
   • D.Administer the next dose of the antibiotic before reassessing.

5. 5.A provider prescribes 0.4 mg of a medication subcutaneously for a 45-year-old client. The medication is available as 200 mcg/mL. How many mL should the nurse administer?

   • A.0.2 mL
   • B.2 mL
   • C.4 mL
   • D.20 mL
