Q&A (2026/2027) | Nightingale College
1. A client is prescribed 8 ounces of water. How many milliliters should the
nurse document?
A) 240 mL
B) 160 mL
C) 300 mL
D) 120 mL
Correct Answer: A) 240 mL
Rationale: One ounce equals 30 mL. Multiplying 8 ounces by 30 mL/oz gives 240
mL. Accurate fluid conversions are essential for intake and output
documentation and medication preparation.
2. A prescription reads 0.5 gram of a medication. The pharmacy supplies 250 mg
tablets. How many tablets should the nurse administer?
A) 1 tablet
B) 2 tablets
C) 3 tablets
D) 4 tablets
Correct Answer: B) 2 tablets
,Rationale: Convert 0.5 g to 500 mg. Then divide 500 mg by 250 mg per tablet to
get 2 tablets. This demonstrates mastery of metric conversions.
3. A prescription reads: Amoxicillin 500 mg PO every 12 hours. Available tablets
are 250 mg each. How many tablets are given per dose?
A) 1 tablet
B) 3 tablets
C) 2 tablets
D) 4 tablets
Correct Answer: C) 2 tablets
Rationale: Desired dose 500 mg divided by 250 mg per tablet equals 2 tablets.
Using the desired over have method ensures correct oral medication dosing.
4. A client with cardiogenic shock weighs 100 kg and is receiving dopamine at 5
mcg/kg/min. How many mcg per minute is the client receiving?
A) 100 mcg/min
B) 250 mcg/min
C) 1000 mcg/min
D) 500 mcg/min
Correct Answer: D) 500 mcg/min
, Rationale: Multiply the weight in kilograms by the dose in mcg/kg/min: 100 kg ×
5 mcg/kg/min = 500 mcg/min. Weight-based calculations require precise
conversion.
5. The nurse is to infuse 1000 mL of normal saline over 8 hours. What rate
should the infusion pump be set at?
A) 125 mL/hr
B) 100 mL/hr
C) 150 mL/hr
D) 75 mL/hr
Correct Answer: A) 125 mL/hr
Rationale: Total volume 1000 mL divided by time 8 hours equals 125 mL/hr.
Infusion pumps are typically programmed in mL/hr.
6. An IV of 1000 mL is to infuse over 10 hours. The drop factor is 15 gtt/mL.
What is the drip rate in gtt/min?
A) 20 gtt/min
B) 25 gtt/min
C) 30 gtt/min
D) 15 gtt/min
Correct Answer: B) 25 gtt/min
