Questions And Actual Answers.
The doctor orders an IV infusion of D5W 1000 mL to infuse over the next 8 hours. The IV set delivers 15
gtt/min. What is the correct rate of flow? (Answer in gtt/min rounded to the nearest whole number). -
Answer 31 gtt/min
((1000 mL x 15 gtt/min) ÷ (8 hrs. x 60 min) = 31.25 --> 31 gtt/min))
The 10:00 am medications scheduled for your patient include Keflex 1.5 G in 50 mL of a 5% Dextrose
solution. According to the pharmacy this preparation should be administered in 30 minutes. The IV
tubing on your unit delivers 15 gtt/mL. What is the correct rate of flow in drops per minute? (Answer in
gtt/min rounded to the nearest whole number). - Answer 25 gtts/min
((50 mL x 15 gtt/mL) ÷ 30 min = 25 gtt/min)
A patient, admitted with a head injury, has an order to start 1000 cc of D5NS at 30 mL/h. The IV tubing
has a calibration of 60 gtt/mL. What is the correct rate of flow for this patient? (Answer in gtt/min
rounded to the nearest whole number). - Answer 30 gtt/min
((30 mL/h x 60 gtt/mL) ÷ 60 min = 30 gtt/min)
The doctor orders 1.5 litres of Lactated Ringers solution to be administered intravenously to your patient
over the next 12 hours. Calculate the rate of flow if the IV tubing delivers 20 gtt/mL. (Answer in gtt/min
rounded to the nearest whole number). - Answer 42 gtt/min
(1.5 L x 1000 = 1500 mL; (1500 mL x 20 gtt/mL) ÷ (12 hrs. x 60 min) = 41.66 --> 42 gtt/min)
On Wednesday afternoon, your patient returns from surgery with an IV fluid order for 1000 cc every 8
hours. On Thursday morning at 8:00 am, you assess that 600 mL of a 1L bag has been absorbed. The
physician orders the remainder of that bag to infuse over the next 6 hours. You know that the IV tubing
used by your unit delivers 10 gtt/mL. What will be the correct rate of flow? - Answer 11 gtt/min
(1000 cc - 600 mL = 400 mL left; (400 mL x 10 gtt/mL) ÷ (6 hrs. x 60 min) 11.11 --> 11 gtt/min)
, An intravenous line has been inserted into a patient. Fluid is being delivered at a rate of 42 mL/h. How
much fluid will the patient receive in 2 hours? - Answer 84 mL
(42 mL/h x 2 hrs. = 84 mL)
A female patient is receiving Hartmann's solution at a rate of 125 mL/h. How much solution will she
receive over 5 hours? - Answer 625 mL
(125 mL/h x 5 hrs. = 625 mL)
A boy is to be given dextrose 5% via an infusion pump. If the pump is set at 60 mL/h, how much dextrose
will he receive in 12 hours? - Answer 720 mL
(60 mL/h x 12 hrs. = 720 mL)
A patient is to receive 100 mL of normal saline, I.V. If the infusion pump is set to deliver 150 mL/h, how
long will the infusion take? - Answer 40 minutes
(0.05 100 mL ÷ 150 mL/h = 2/3 hour or 40 minutes)
What is the required flow rate of a volumetric infusion pump to deliver 2 litres of dextrose 4% in 1/5
normal saline over 15 hours? (Answer in mL/h rounded to the nearest whole number). - Answer 133
mL/h
What is the required flow rate of a volumetric infusion pump to deliver one litre of normal saline over 24
hours? (Answer in mL/h rounded to the nearest whole number). - Answer 42 mL/h
(1000 mL (1 litre) ÷ 24 hrs. = 41.6 --> 42 mL/h)
What is the correct setting for a burette pump to administer 120 mL of fluid containing 500 mg of
vancomycin in 50 minutes? (Answer in mL/h rounded to the nearest whole number). - Answer 144
mL/h
(120 mL x (60 min ÷ 50 min) = 144 mL/h)
What is the correct setting for a burette pump to administer 80 mL of fluid containing 80 mg of
gentamicin in 45 minutes? (Answer in mL/h rounded to the nearest whole number). - Answer 107 mL/h
