1. The healthcare provider orders 1.5 grams of an antibiotic to be administered orally in two
divided doses. The medication is available in 250 mg tablets. How many tablets should the
nurse administer per dose?
A. 4 tablets
B. 3 tablets
C. 6 tablets
D. 2 tablets
Answer: B
Rationale: First, convert the total daily dose from grams to milligrams, which results in
1,500 mg. Since the dose is divided into two parts, each individual dose is 750 mg. Dividing
the 750 mg dose by the 250 mg tablet strength results in exactly 3 tablets per dose.
2. A patient is to receive 1,000 mL of 0.9% Normal Saline over 8 hours. The IV tubing has a
drop factor of 15 gtt/mL. What is the correct flow rate in drops per minute (gtt/min)? Round
to the nearest whole number.
A. 31 gtt/min
B. 21 gtt/min
,C. 42 gtt/min
D. 125 gtt/min
Answer: A
Rationale: To find the flow rate, multiply the total volume of 1,000 mL by the drop factor
of 15 to get the total drops. Then, divide the total drops by the total time in minutes, which
is 480 minutes (8 hours times 60). The calculation 15,000 divided by 480 equals 31.25,
which rounds to 31 gtt/min.
3. A child weighing 44 lbs is prescribed a medication at a dosage of 15 mg/kg. How many
milligrams should the nurse administer?
A. 300 mg
B. 660 mg
C. 150 mg
D. 440 mg
Answer: A
Rationale: The first step is to convert the child’s weight from pounds to kilograms by
dividing 44 lbs by 2.2, which equals 20 kg. Next, multiply the weight of 20 kg by the
prescribed dose of 15 mg/kg. This calculation results in a total dose of 300 mg to be
administered.
, 4. The order is for Heparin 800 units/hour. The pharmacy provides a 500 mL bag containing
25,000 units of Heparin. What rate should the nurse set the IV pump in mL/hr?
A. 10 mL/hr
B. 16 mL/hr
C. 25 mL/hr
D. 32 mL/hr
Answer: B
Rationale: Start by determining the concentration of the Heparin solution, which is 25,000
units divided by 500 mL, resulting in 50 units/mL. Then, divide the ordered hourly dose of
800 units by the concentration of 50 units/mL. The calculation shows that the nurse should
set the pump to 16 mL/hr.
5. A patient is prescribed 0.125 mg of Digoxin. The medication is available as 250 mcg tablets.
How many tablets should the nurse administer?
A. 0.5 tablets
B. 1 tablet
C. 2 tablets
D. 1.5 tablets
Answer: A
