,Q1. A provider orders 0.9% sodium chloride at 75 mL/hr. The drop factor is 15
gtt/mL. How many gtt/min should the nurse regulate the infusion?
A. 18.75 gtt/min
B. 19 gtt/min
C. 20 gtt/min
D. 17 gtt/min
Correct Answer: A. 18.75 gtt/min
Rationale: Using the formula: (75 mL/hr × 15 gtt/mL) / 60 min/hr = 18.75 gtt/min.
Rounding to the nearest whole number gives 19, but since the question asks for the
calculated rate, 18.75 is the exact answer.
Why Wrong:
B - This is the rounded whole number, but the exact calculated value is 18.75.
C - This would result from using 16 gtt/mL or incorrect rounding.
D - This results from misplacing the decimal or using 14 gtt/mL.
Reference: Gray Morris, D. (2026). Calculate with Confidence, 8th ed., Ch. 13.
Q2. A patient is receiving dopamine at 5 mcg/kg/min. The patient weighs 70 kg. The
concentration is 400 mg in 250 mL. At what rate (mL/hr) should the infusion pump be
set?
A. 13.1 mL/hr
B. 15.0 mL/hr
C. 10.5 mL/hr
D. 12.0 mL/hr
Correct Answer: A. 13.1 mL/hr
Rationale: First, calculate dose per hour: 5 mcg/kg/min × 70 kg × 60 min = 21,000 mcg/hr
= 21 mg/hr. Then, concentration: 400 mg/250 mL = 1.6 mg/mL. Rate = 21 mg/hr ÷ 1.6
mg/mL = 13.125 mL/hr 13.1 mL/hr.
Why Wrong:
B - This might result from using 400 mg/250 mL incorrectly or rounding up too early.
C - This would occur if the patient weight was omitted or miscalculated.
D - This could result from using 4 mg/kg/min or a wrong conversion.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th ed., Ch. 18.
Q3. A medication order reads: 'Give 500 mg of a drug that is available as 250 mg per
5 mL. How many mL will you administer?'
A. 5 mL
B. 10 mL
C. 2.5 mL
Page 3
, D. 7.5 mL
Correct Answer: B. 10 mL
Rationale: Using ratio: 250 mg/5 mL = 500 mg/x mL. Cross-multiply: 250x = 2500, x =
10 mL.
Why Wrong:
A - This is the volume for 250 mg, not 500 mg.
C - This would be the volume if the concentration were 500 mg/5 mL.
D - This results from an arithmetic error in cross-multiplication.
Reference: Gray Morris, D. (2026). Calculate with Confidence, 8th ed., Ch. 9.
Q4. A patient is to receive 1 L of lactated Ringer's over 8 hours. The drop factor is 20
gtt/mL. What is the flow rate in gtt/min?
A. 42 gtt/min
B. 40 gtt/min
C. 45 gtt/min
D. 38 gtt/min
Correct Answer: A. 42 gtt/min
Rationale: Volume per hour = 1000 mL / 8 hr = 125 mL/hr. Then, (125 mL/hr × 20 gtt/mL)
/ 60 min/hr = 41.67 gtt/min, which rounds to 42 gtt/min.
Why Wrong:
B - This would result from rounding down to 40 without proper calculation.
C - This might come from using 1.5 L or a drop factor of 22.
D - This could result from using 15 gtt/mL or incorrect division.
Reference: Gray Morris, D. (2026). Calculate with Confidence, 8th ed., Ch. 14.
Q5. A child weighs 30 lb. The order is for 5 mg/kg of a medication. The concentration
is 50 mg/mL. How many mL should be administered?
A. 1.36 mL
B. 1.5 mL
C. 2.0 mL
D. 0.68 mL
Correct Answer: A. 1.36 mL
Rationale: Convert weight: 30 lb ÷ 2.2 = 13.64 kg. Dose = 5 mg/kg × 13.64 kg = 68.2 mg.
Volume = 68.2 mg ÷ 50 mg/mL = 1.36 mL.
Why Wrong:
B - This would result from rounding kg to 14 and using 70 mg.
C - This would occur if the dose was calculated as 10 mg/kg or using the wrong
concentration.
