SECTION 1: Basic Math and Algebra Review (12 Questions)
Q1: A healthcare provider orders 750 mg of a medication. The available tablets are 250
mg each. How many tablets should be administered?
A. 2 tablets
B. 2.5 tablets
C. 3 tablets [CORRECT]
D. 4 tablets
Correct Answer: C
Rationale: Correct because 750 mg ÷ 250 mg per tablet = 3 tablets. The calculation
yields the exact number of whole tablets needed to fulfill the medication order.
Q2: A patient's body mass index (BMI) is calculated using the formula BMI = (weight in
pounds × 703) ÷ (height in inches)². If a patient weighs 180 pounds and is 70 inches tall,
what is their BMI? (Round to one decimal place.)
A. 24.2
B. 25.9 [CORRECT]
C. 26.8
,D. 28.1
Correct Answer: B
Rationale: Correct because (180 × 703) ÷ (70)² = 126,540 ÷ 4,900 = 25.824..., which
rounds to 25.9. The calculation yields the standard BMI classification for this patient.
Q3: An IV infusion of 1,000 mL is to be administered over 8 hours. What is the flow rate
in mL per hour?
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
standard infusion rate for this volume over the specified time period.
Q4: Convert 0.75 to a fraction in lowest terms.
A. 3/5
B. 2/3
C. 3/4 [CORRECT]
D. 7/10
Correct Answer: C
,Rationale: Correct because 0.75 = 75/100 = 3/4 when reduced to lowest terms. The
conversion yields the simplest fractional representation.
Q5: A hospital has 250 nurses, and 40% work the night shift. How many nurses work the
night shift?
A. 75
B. 90
C. 100 [CORRECT]
D. 125
Correct Answer: C
Rationale: Correct because 250 × 0.40 = 100 nurses. The calculation yields the exact
number of night shift personnel based on the given percentage.
Q6: Solve for x: 3(x + 4) = 2x + 18
A. x = 2
B. x = 4
C. x = 6 [CORRECT]
D. x = 8
Correct Answer: C
Rationale: Correct because 3x + 12 = 2x + 18, therefore x = 6. The algebraic solution
yields the value that satisfies the equation.
, Q7: Express 4,500,000 in scientific notation.
A. 4.5 × 10⁵
B. 45 × 10⁵
C. 4.5 × 10⁶ [CORRECT]
D. 0.45 × 10⁷
Correct Answer: C
Rationale: Correct because 4,500,000 = 4.5 × 10⁶ in proper scientific notation. The
conversion yields the standard form with one digit before the decimal point.
Q8: A medication dosage is 0.125 mg. The available concentration is 0.25 mg per 2 mL.
How many mL should be administered?
A. 0.5 mL
B. 1.0 mL [CORRECT]
C. 1.5 mL
D. 2.0 mL
Correct Answer: B
Rationale: Correct because (0.125 mg ÷ 0.25 mg) × 2 mL = 1.0 mL. The proportional
calculation yields the correct volume to administer.
