SECTION 1: BASIC DOSAGE CALCULATIONS
Q1: A patient is prescribed acetaminophen 500 mg PO every 6 hours as needed for pain.
The medication is available in 250 mg tablets. How many tablets should the nurse
administer per dose?
A. 0.5 tablet
B. 1 tablet
C. 2 tablets [CORRECT]
D. 4 tablets
Correct Answer: C
Rationale: Using the formula method (Desired/Have × Quantity): 500 mg ÷ 250 mg × 1
tablet = 2 tablets. Distractor A results from dividing 250 by 500 instead. Distractor B
represents the have dose only. Distractor D doubles the correct answer. Always verify
the label matches the ordered medication before administration.
Q2: The physician orders digoxin 0.125 mg PO daily. The pharmacy supplies digoxin
0.25 mg scored tablets. How many tablets should the nurse administer?
A. 0.25 tablet
B. 0.5 tablet [CORRECT]
C. 1 tablet
D. 2 tablets
Correct Answer: B
Rationale: Calculation: 0.125 mg (desired) ÷ 0.25 mg (have) × 1 tablet = 0.5 tablet.
Because the tablet is scored, it can be safely split. Distractor A incorrectly divides have
by desired. Distractor C represents the full tablet strength. Distractor D would deliver a
toxic double dose. Verify apical pulse for 1 full minute before administering digoxin.
,Q3: A patient is ordered cephalexin 1.5 g PO twice daily. The available capsules are 500
mg each. How many capsules should the nurse administer per dose?
A. 1 capsule
B. 2 capsules
C. 3 capsules [CORRECT]
D. 5 capsules
Correct Answer: C
Rationale: First convert grams to milligrams: 1.5 g = 1500 mg. Then calculate: 1500 mg
÷ 500 mg × 1 capsule = 3 capsules. Distractor A ignores the conversion. Distractor B
miscalculates by using 1 g = 1000 mg but dividing incorrectly. Distractor D adds the
converted dose to the capsule strength. Always convert to the same unit of
measurement before calculating.
Q4: The provider orders furosemide 75 mg PO now. The oral solution is labeled 25 mg
per 5 mL. How many milliliters should the nurse administer?
A. 5 mL
B. 10 mL
C. 15 mL [CORRECT]
D. 25 mL
Correct Answer: C
Rationale: Using dimensional analysis: (75 mg ÷ 25 mg) × 5 mL = 3 × 5 mL = 15 mL.
Distractor A represents the volume of the have dose. Distractor B incorrectly divides 75
by 25 but forgets to multiply by 5. Distractor D multiplies 75 by 5 without dividing by 25.
Use an oral syringe for accurate measurement of liquid medications.
Q5: A patient is prescribed ibuprofen 240 mg PO every 8 hours. The suspension is
available as 80 mg per 2 mL. How many milliliters should the nurse administer?
A. 2 mL
B. 4 mL
C. 6 mL [CORRECT]
D. 8 mL
Correct Answer: C
Rationale: (240 mg ÷ 80 mg) × 2 mL = 3 × 2 mL = 6 mL. Alternatively, the concentration
is 40 mg/mL, so 240 mg ÷ 40 mg/mL = 6 mL. Distractor A is the vehicle volume.
,Distractor B uses the concentration as 60 mg/mL. Distractor D doubles the correct
answer. Shake suspensions well before pouring to ensure uniform drug distribution.
Q6: The physician orders sublingual nitroglycerin 0.3 mg PRN for chest pain. The
available tablets are 0.15 mg each. How many tablets should the nurse administer?
A. 1 tablet
B. 2 tablets [CORRECT]
C. 3 tablets
D. 4 tablets
Correct Answer: B
Rationale: 0.3 mg ÷ 0.15 mg × 1 tablet = 2 tablets. Nitroglycerin is a high-alert
medication for angina. Distractor A under-doses the patient. Distractor C triples the
correct amount. Distractor D would cause significant hypotension. Assess blood
pressure before and after administration; hold if systolic BP is below 90 mmHg.
Q7: The provider orders morphine sulfate 15 mg IM. The vial is labeled 30 mg/mL. How
many milliliters should the nurse administer?
A. 0.25 mL
B. 0.5 mL [CORRECT]
C. 1 mL
D. 2 mL
Correct Answer: B
Rationale: 15 mg ÷ 30 mg/mL = 0.5 mL. For intramuscular injections, volumes up to 1
mL are acceptable for deltoid sites. Distractor A divides 15 by 60 (confusing with
minutes). Distractor C is the volume if the dose were 30 mg. Distractor D doubles the
correct volume. Use a 1 mL tuberculin syringe for precise measurement of opioid
medications.
Q8: A patient is ordered amoxicillin 1 g PO three times daily. The oral suspension is
labeled 250 mg per 5 mL. How many milliliters should the nurse administer per dose?
A. 5 mL
B. 10 mL
C. 15 mL
D. 20 mL [CORRECT]
Correct Answer: D
, Rationale: Convert 1 g to 1000 mg. Then: (1000 mg ÷ 250 mg) × 5 mL = 4 × 5 mL = 20
mL. Distractor A is the vehicle volume. Distractor B uses 500 mg as the ordered dose.
Distractor C miscalculates the ratio. Large oral volumes may be split into two
administrations if the patient has difficulty swallowing.
Q9: The physician orders ondansetron 40 mg IV push. The vial is labeled 20 mg per 2
mL. How many milliliters should the nurse administer?
A. 2 mL
B. 4 mL [CORRECT]
C. 6 mL
D. 8 mL
Correct Answer: B
Rationale: (40 mg ÷ 20 mg) × 2 mL = 2 × 2 mL = 4 mL. Alternatively, concentration is 10
mg/mL, so 40 mg ÷ 10 mg/mL = 4 mL. Distractor A is the volume of the have dose.
Distractor C adds 2 mL unnecessarily. Distractor D doubles the correct volume.
Administer IV push over 2-5 minutes to prevent cardiac arrhythmias.
Q10: A patient is prescribed warfarin 2.5 mg PO daily. The available tablets are 5 mg
scored tablets. How many tablets should the nurse administer?
A. 0.25 tablet
B. 0.5 tablet [CORRECT]
C. 1 tablet
D. 2 tablets
Correct Answer: B
Rationale: 2.5 mg ÷ 5 mg × 1 tablet = 0.5 tablet. Warfarin is a high-alert anticoagulant
requiring careful dosing. Distractor A results from dividing 5 by 2.5 incorrectly.
Distractor C would deliver double the ordered dose, increasing bleeding risk. Distractor
D is a lethal overdose. Verify INR results before administration and confirm with a
second nurse per policy.
Q11: The provider orders metformin 0.5 g PO twice daily. The pharmacy supplies 250
mg tablets. How many tablets should the nurse administer per dose?
A. 1 tablet
B. 2 tablets [CORRECT]
