1. A patient is prescribed 1500 mL of 0.9% Normal Saline
to infuse over 12 hours. The IV tubing has a drop factor of
20 gtt/mL. What is the flow rate in gtt/min?
A. 42 gtt/min
B. 125 gtt/min
C. 31 gtt/min
D. 83 gtt/min
- detailed answer 100% correct :-A
Rationale: 12 hours = 720 minutes. Formula: (Total Volume ×
Drop Factor) / Time in minutes = (1500 mL × 20 gtt/mL) / 720
min = 41.66 gtt/min, rounded to 42 gtt/min.
,2. A patient is ordered to receive 3 L of Lactated Ringer's
over 24 hours. The drop factor is 15 gtt/mL. Calculate the
flow rate in gtt/min.
A. 31 gtt/min
B. 42 gtt/min
C. 21 gtt/min
D. 125 gtt/min
- detailed answer 100% correct :-A
Rationale: 3 L = 3000 mL. 24 hours = 1440 minutes. (3000 mL
× 15 gtt/mL) / 1440 min = 31.25 gtt/min, rounded to 31
gtt/min.
3. The provider orders 1 gram of a medication in 250 mL
of
D5W to infuse over 90 minutes. The tubing delivers 10
gtt/mL. How many drops per minute should the nurse set
the IV to deliver? A. 28 gtt/min
B. 42 gtt/min
C. 56 gtt/min
D. 83 gtt/min
- detailed answer 100% correct :-A
Rationale: (250 mL × 10 gtt/mL) / 90 min = 27.77 gtt/min,
rounded to 28 gtt/min. The medication weight (1 gram) is
extraneous for this calculation.
, 4. A patient is receiving an IV at 150 mL/hr. The IV tubing
has a drop factor of 20 gtt/mL. What is the drip rate in
gtt/min?
A. 50 gtt/min
B. 75 gtt/min
C. 150 gtt/min
D. 30 gtt/min
- detailed answer 100% correct :-A
Rationale: (150 mL / 60 min) × 20 gtt/mL = 50 gtt/min.
5. The nurse needs to infuse 350 mL of packed red blood
cells over 2.5 hours. The blood administration set has a
drop factor of 10 gtt/mL. The nurse should set the rate to
deliver how many gtt/min?
A. 23 gtt/min
B. 35 gtt/min
C. 140 gtt/min
D. 58 gtt/min
- detailed answer 100% correct :-A
Rationale: 2.5 hours = 150 minutes. (350 mL × 10 gtt/mL) /
150 min = 23.33 gtt/min, rounded to 23 gtt/min.
6. An IV is infusing at 45 gtt/min using a microdrip set (60
gtt/mL). How many mL/hr is the patient receiving?
A. 45 mL/hr
