,HESI A2 Mathematics Nursing Entrance Practice
Test + 150 Questions & Detailed Rationales
1. A nurse is reviewing a client's fluid intake. The client drank 240 mL of coffee, 120 mL of juice,
and 360 mL of water. What is the total intake in milliliters?
A. 620 mL
B. 700 mL
C. 720 mL
D. 750 mL
Correct Answer: C. 240 + 120 + 360 = 720 mL.
Rationale: Whole number addition involves aligning place values and adding each column. In
clinical practice, accurate intake totals are essential for monitoring fluid balance, especially in
clients with heart failure or renal disease.
2. A client's blood pressure at 8 AM was 128/84 mm Hg, and at noon it was 142/90 mm Hg. By
how much did the systolic pressure increase?
A. 10 mm Hg
B. 14 mm Hg
C. 16 mm Hg
D. 18 mm Hg
,Correct Answer: B. 142 − 128 = 14 mm Hg.
Rationale: Subtraction of whole numbers is used to determine changes in clinical values.
Tracking blood pressure trends helps identify worsening hypertension and evaluate the
effectiveness of interventions.
3. A hospital unit has 15 nurses scheduled for the day shift. If each nurse is assigned 4 clients,
how many total clients can be assigned?
A. 45
B. 55
C. 60
D. 65
Correct Answer: C. 15 × 4 = 60 clients.
Rationale: Multiplication of whole numbers is used in staffing calculations to determine total
workload capacity.
4. A pharmacy has 2,400 tablets of acetaminophen. If the tablets are divided equally into 8
bottles, how many tablets are in each bottle?
A. 250
B. 280
, C. 300
D. 320
Correct Answer: C. 2,400 ÷ 8 = 300 tablets per bottle.
Rationale: Division of whole numbers is used to distribute supplies evenly. Accurate inventory
management ensures adequate medication availability.
5. Evaluate: 8 + 2 × (5 − 3)²
A. 16
B. 20
C. 24
D. 100
Correct Answer: A. Order of operations (PEMDAS): Parentheses: 5 − 3 = 2. Exponents: 2² = 4.
Multiplication: 2 × 4 = 8. Addition: 8 + 8 = 16.
Rationale: PEMDAS ensures consistent evaluation of mathematical expressions. This is critical in
dosage calculations where the order of operations affects the final dose.
6. A warehouse worker ships 25 boxes each day. How many boxes are shipped in 12 days?
