SECTION 1: Basic Math, Algebra, and Healthcare Calculations
(14 Questions)
Q1: A patient is prescribed 750 mg of amoxicillin. The pharmacy has 250 mg tablets
available. How many tablets should the nurse administer?
A. 2 tablets
B. 3 tablets [CORRECT]
C. 4 tablets
D. 5 tablets
Correct Answer: B
Rationale: Correct because 750 mg ÷ 250 mg/tablet = 3 tablets. The calculation yields
the exact number of whole tablets needed for the prescribed dose.
Q2: An IV solution is ordered to infuse at 125 mL/hr. The drop factor is 15 gtt/mL. What
is the drip rate in gtt/min? (Round to the nearest whole number)
A. 28 gtt/min
B. 30 gtt/min
C. 31 gtt/min [CORRECT]
D. 33 gtt/min
Correct Answer: C
Rationale: Correct because (125 mL/hr × 15 gtt/mL) ÷ 60 min/hr = 1,875 ÷ 60 = 31.25
gtt/min, which rounds to 31 gtt/min. The formula is (mL/hr × drop factor) ÷ 60 minutes.
Q3: A patient's temperature is 38.5°C. What is the equivalent temperature in Fahrenheit?
(Formula: °F = (°C × 9/5) + 32)
A. 99.5°F
B. 100.3°F
,C. 101.3°F [CORRECT]
D. 102.4°F
Correct Answer: C
Rationale: Correct because (38.5 × 9/5) + 32 = 69.3 + 32 = 101.3°F. The calculation
yields the precise conversion using the standard Celsius-to-Fahrenheit formula.
Q4: A medication order states: "Give 0.5 g PO every 6 hours." The available tablets are
250 mg each. How many tablets should be administered per dose?
A. 1 tablet
B. 2 tablets [CORRECT]
C. 3 tablets
D. 4 tablets
Correct Answer: B
Rationale: Correct because 0.5 g = 500 mg, and 500 mg ÷ 250 mg/tablet = 2 tablets.
The conversion from grams to milligrams must be performed before calculating the
tablet count.
Q5: Solve for x: 2(x + 5) - 3 = 3(x - 2) + 7
A. x = 2
B. x = 4
C. x = 5
D. x = 6 [CORRECT]
Correct Answer: D
Rationale: Correct because expanding yields 2x + 10 - 3 = 3x - 6 + 7, simplifying to 2x + 7
= 3x + 1, then x = 6. Verification: 2(6+5)-3 = 19 and 3(6-2)+7 = 19, confirming the
solution.
Q6: A patient weighs 154 lbs. What is the patient's weight in kilograms? (Round to one
decimal place; 1 kg = 2.2 lbs)
A. 68.2 kg
B. 70.0 kg [CORRECT]
C. 72.5 kg
D. 75.0 kg
Correct Answer: B
Rationale: Correct because 154 lbs ÷ 2.2 lbs/kg = 70.0 kg. The conversion yields exactly
70.0 kg when rounded to one decimal place.
, Q7: Calculate the body mass index (BMI) for a patient who is 1.75 m tall and weighs 85
kg. (Formula: BMI = weight(kg) / height(m)²)
A. 25.7 kg/m²
B. 26.8 kg/m²
C. 27.8 kg/m² [CORRECT]
D. 28.9 kg/m²
Correct Answer: C
Rationale: Correct because BMI = 85 / (1.75)² = .0625 = 27.755 kg/m², which
rounds to 27.8 kg/m². The calculation follows the standard BMI formula.
Q8: An IV bag contains 1,000 mL of D5W and is set to infuse over 8 hours. What is the
flow rate in mL/hr?
A. 100 mL/hr
B. 125 mL/hr [CORRECT]
C. 150 mL/hr
D. 200 mL/hr
Correct Answer: B
Rationale: Correct because 1,000 mL ÷ 8 hours = 125 mL/hr. The calculation yields the
hourly infusion rate for the prescribed volume and time.
Q9: Express 0.00456 in scientific notation.
A. 4.56 × 10⁻²
B. 4.56 × 10⁻³ [CORRECT]
C. 45.6 × 10⁻⁴
D. 0.456 × 10⁻²
Correct Answer: B
Rationale: Correct because 0.00456 = 4.56 × 10⁻³. The decimal point moves three
places to the right, giving a negative exponent of 3 in proper scientific notation.
Q10: A medication is available as 0.125 mg tablets. The ordered dose is 0.375 mg. How
many tablets should be administered?
A. 2 tablets
B. 3 tablets [CORRECT]
C. 4 tablets
D. 5 tablets
