Q1: The 'Six Rights' of medication administration include which of the following?
A. Right client, room, bed, chair, door, and window
B. Right client, drug, dose, route, time, and documentation [CORRECT]
C. Right color, size, shape, taste, and smell
D. Right family, doctor, nurse, and pharmacist

Q2: A client is prescribed 500 mg of a medication, and the available tablet is 250 mg. How many tablets should be
given?
A. 1 tablet
B. 0.5 tablet
C. 4 tablets
D. 2 tablets [CORRECT]
Correct Answer: D
Rationale: 500 ÷ 250 = 2 tablets. The other options misapply the ratio.
Q3: A medication is ordered at 20 mg/kg for a client weighing 70 kg. The total dose is:
A. 1,400 mg [CORRECT]
B. 700 mg
C. 2,000 mg
D. 90 mg
Correct Answer: A
Rationale: 20 mg/kg × 70 kg = 1,400 mg. The other options misapply the calculation.
Q4: A client is prescribed 1,000 mL of IV fluid over 8 hours. The hourly rate is:
A. 100 mL/hour
B. 250 mL/hour
C. 125 mL/hour [CORRECT]
D. 1,000 mL/hour
Correct Answer: C
Rationale: 1,000 ÷ 8 = 125 mL/hour. The other options misapply the calculation.
Q5: An IV medication is ordered at 500 mg in 250 mL to infuse over 2 hours. The rate in mL/hour is:
A. 250 mL/hour
B. 50 mL/hour
C. 125 mL/hour [CORRECT]
D. 500 mL/hour
Correct Answer: C
Rationale: 250 mL ÷ 2 hours = 125 mL/hour. The other options misapply the calculation.
Q6: A client is prescribed 1500 mg of a medication that is available as 500 mg tablets. How many tablets?
A. 2 tablets
B. 5 tablets
C. 3 tablets [CORRECT]
D. 1 tablet

A. 150 mg [CORRECT]
B. 300 mg
C. 75 mg
D. 30 mg
Correct Answer: A
Rationale: Total daily = 5 × 60 = 300 mg; divided by 2 = 150 mg per dose. The other options are incorrect.
Q9: Which of the following is the correct abbreviation to avoid when documenting medication doses?
A. mg
B. mL
C. PO
D. 'U' for units (write 'units') [CORRECT]
Correct Answer: D
Rationale: 'U' is on the do-not-use list because it can be misread. mg, mL, and PO are acceptable when written correctly.
Q10: When calculating an IV infusion rate, the nurse uses:
A. The client's height

given?
A. 5 mL
B. 2.5 mL
C. 10 mL [CORRECT]
D. 20 mL
Correct Answer: C
Rationale: 250 ÷ (125/5) = 250 ÷ 25 = 10 mL. The other options misapply the concentration.

A. 2 tablets
B. 0.5 tablet
C. 4 tablets
D. 1 tablet [CORRECT]

A. Rushing administration
B. Using unlabeled syringes
C. Relying on memory
D. Verifying the rights and checking the label three times [CORRECT]
