1. The healthcare provider orders 1,000 mL of 0.9% Normal Saline to infuse over 8 hours. At
what rate should the nurse set the infusion pump in mL/hr?
A. 125 mL/hr
B. 100 mL/hr
C. 150 mL/hr
D. 80 mL/hr
Answer: A
Rationale: To calculate the hourly rate, the total volume of 1,000 mL is divided by the total
time of 8 hours. This calculation results in exactly 125 mL per hour. The nurse must ensure
the pump is programmed correctly to prevent fluid overload or dehydration.
2. A client is prescribed 500 mg of an antibiotic to be administered in 100 mL of D5W over 30
minutes. What is the infusion rate in mL/hr?
A. 200 mL/hr
B. 100 mL/hr
C. 50 mL/hr
,D. 150 mL/hr
Answer: A
Rationale: The volume to be infused is 100 mL over a period of 0.5 hours. Dividing 100 mL
by 0.5 hours yields an infusion rate of 200 mL/hr. Setting the pump to this rate ensures the
medication is delivered within the prescribed thirty-minute window.
3. The nurse is preparing to administer Heparin at 1,100 units/hr. The pharmacy provides a
bag containing 25,000 units of Heparin in 500 mL of 5% Dextrose. What is the pump setting in
mL/hr?
A. 11 mL/hr
B. 25 mL/hr
C. 22 mL/hr
D. 44 mL/hr
Answer: C
Rationale: First, determine the concentration of the Heparin solution by dividing 25,000
units by 500 mL, which equals 50 units/mL. Next, divide the ordered dose of 1,100 units/hr
by the concentration of 50 units/mL. This results in an infusion rate of 22 mL/hr to deliver
the correct dosage.
4. A pediatric patient weighing 22 lbs is ordered to receive a medication at 5 mg/kg. How
many milligrams should the nurse administer?
A. 50 mg
, B. 110 mg
C. 44 mg
D. 100 mg
Answer: A
Rationale: The first step is to convert the weight from pounds to kilograms by dividing 22
by 2.2, which equals 10 kg. Then, multiply the weight of 10 kg by the ordered dose of 5
mg/kg to find the total dose. The final calculated dose for this pediatric patient is 50 mg.
5. An IV of 0.45% NS is infusing at 75 mL/hr via a gravity set with a drop factor of 15 gtt/mL.
What is the drip rate in gtt/min?
A. 19 gtt/min
B. 15 gtt/min
C. 25 gtt/min
D. 31 gtt/min
Answer: A
Rationale: To find the drip rate, multiply the hourly rate of 75 mL by the drop factor of 15
and then divide by 60 minutes. The calculation (75 * 15) / 60 equals 18.75. According to
standard practice, this value is rounded to the nearest whole number, which is 19 gtt/min.
