Question 1
The healthcare provider orders 500 mg of
amoxicillin oral suspension. The pharmacy supplies
250 mg/5 mL. How many mL will the nurse
administer?
A) 5 mL
B) 7.5 mL
C) 10 mL
D) 12.5 mL
,Correct Answer: C
Rationale: Desired dose 500 mg divided by
available dose 250 mg equals 2. Multiply 2 by the
volume 5 mL to get 10 mL.
Question 2
A patient is to receive 1,000 mL of normal saline
over 8 hours. The IV set delivers 15 gtt/mL.
Calculate the flow rate in gtt/min.
A) 21 gtt/min
B) 31 gtt/min
C) 42 gtt/min
D) 50 gtt/min
Correct Answer: B
Rationale: Total volume 1,000 mL divided by time
in minutes 480 min equals 2.08 mL/min. Multiply
by drop factor 15 gtt/mL equals 31.25, rounded to
31 gtt/min.
Question 3
The provider prescribes 0.25 mg of digoxin IV. The
vial is labeled 0.5 mg/2 mL. How many mL will the
nurse give?
,A) 0.5 mL
B) 1 mL
C) 1.5 mL
D) 2 mL
Correct Answer: B
Rationale: Desired 0.25 mg divided by available 0.5
mg equals 0.5. Multiply by 2 mL equals 1 mL.
Question 4
A child weighs 22 lb. The order is for 10 mg/kg/day
divided every 8 hours. How many mg per dose?
A) 25 mg
B) 33.3 mg
C) 50 mg
D) 100 mg
Correct Answer: B
Rationale: Convert 22 lb to kg by dividing by 2.2
equals 10 kg. Total daily dose is 10 mg × 10 kg =
100 mg. Divided every 8 hours means 3 doses daily,
so 100 mg ÷ 3 = 33.3 mg per dose.
Question 5
The physician orders 1,000 mL D5W to infuse at 125
, mL/hr. How many hours will the IV run?
A) 6 hours
B) 7 hours
C) 8 hours
D) 10 hours
Correct Answer: C
Rationale: Total volume 1,000 mL divided by rate
125 mL/hr equals 8 hours.
Question 6
Order: morphine sulfate 8 mg IM every 4 hours prn
pain. Available: morphine 10 mg/mL. How many mL
will the nurse administer?
A) 0.6 mL
B) 0.8 mL
C) 1 mL
D) 1.2 mL
Correct Answer: B
Rationale: Desired 8 mg divided by available 10 mg
equals 0.8. Multiply by 1 mL equals 0.8 mL.
Question 7
A medication is ordered at 5 mcg/kg/min. The
