SECTION 1: DOSAGE CALCULATION
Chapter 1: Basic Dosage Calculations
,1. A nurse is preparing to administer 1,000 mL of 0.9% sodium chloride IV to
infuse over 8 hr. The drop factor is 15 gtt/mL. The nurse should set the
manual IV infusion to deliver how many gtt/min?
A. 125 gtt/min
B. 21 gtt/min
C. 42 gtt/min
D. 31 gtt/min
Answer: D
Rationale: Total volume (1000 mL) / Total time in minutes (8 hr × 60 min =
480 min) × Drop factor (15 gtt/mL) = 31.25, rounded to 31 gtt/min. This
calculation ensures the correct flow rate for manual IV infusion.
2. A nurse is preparing to administer heparin 15,000 units subcutaneously
every 12 hr. The amount available is heparin injection 20,000 units/mL. How
many mL should the nurse administer per dose?
A. 0.5 mL
B. 0.75 mL
C. 1.25 mL
D. 1.5 mL
Answer: B
Rationale: Desired (15,000 units) / Have (20,000 units) × Quantity (1 mL) =
0.75 mL. This is the correct dose to administer subcutaneously.
, 3. A nurse is preparing to administer 0.9% sodium chloride 2 L IV to infuse
over 12 hr. The nurse should set the IV pump to deliver how many mL/hr?
A. 150 mL/hr
B. 167 mL/hr
C. 125 mL/hr
D. 200 mL/hr
Answer: B
Rationale: 2 L = 2000 mL. 2000 mL / 12 hr = 166.666, rounded to 167
mL/hr. This ensures the IV pump delivers the correct volume per hour.
4. A nurse is preparing to administer dopamine 5 mcg/kg/min by continuous
IV infusion to a client who weighs 176 lb. The available dopamine is 400 mg
in 250 mL D5W. The nurse should set the IV pump to deliver how many
mL/hr?
A. 25 mL/hr
B. 15 mL/hr
C. 18.5 mL/hr
D. 15.0 mL/hr
Answer: B
Rationale: 176 lb / 2.2 = 80 kg. 5 mcg × 80 kg × 60 min = 24,000 mcg/hr
= 24 mg/hr. (24 mg / 400 mg) × 250 mL = 15 mL/hr. This calculation
ensures accurate delivery of the vasoactive medication.
