Epic Skills Assessment Quantitative Reasoning & Math 4 — Questions and Answers
Question 1: A ratio table shows that for every 3 registered nurses, there are 2 licensed practical nurses. If there are 18 registered nurses, how many LPNs are there?
- 9
- 10
- 12 (Correct answer)
- 14
Correct answer: 12
If 3 RNs → 2 LPNs, then 18 RNs → (18 ÷ 3) × 2 = 12 LPNs.
Question 2: A pie chart shows that 40% of hospital costs are staffing, 25% supplies, 20% facilities, and 15% administration. If the total budget is $800,000, how much is spent on supplies?
- $160,000
- $180,000
- $200,000 (Correct answer)
- $220,000
Correct answer: $200,000
25% × $800,000 = $200,000.
Question 3: An IV drip delivers 500 mL over 4 hours. At what rate, in mL per minute, is the fluid delivered?
- 1.5 mL/min
- 2.0 mL/min
- 2.1 mL/min (Correct answer)
- 2.5 mL/min
Correct answer: 2.1 mL/min
500 mL ÷ (4 × 60 min) = 500 ÷ 240 ≈ 2.08 ≈ 2.1 mL/min.
Question 4: A dataset of patient ages has a mean of 45, a median of 42, and a mode of 38. Which measure of central tendency is most affected by extreme (outlier) values?
- Mode
- Median
- Mean (Correct answer)
- Range
Correct answer: Mean
The mean is most sensitive to outliers because it uses every value in its calculation.
Question 5: A department's headcount grew from 24 to 30 employees in one year. What is the percentage increase?
- 20%
- 22%
- 25% (Correct answer)
- 28%
Correct answer: 25%
(30 − 24) ÷ 24 × 100 = 6 ÷ 24 × 100 = 25%.
Question 6: A table shows test scores for a group: 88, 92, 76, 85, 92, 79, 92. What is the mode?
- 76
- 85
- 88
- 92 (Correct answer)
Correct answer: 92
92 appears three times, more than any other value, making it the mode.
Question 7: A clinic's monthly costs follow the equation C = 1,500n + 8,000, where n is the number of patients. What is the cost when 50 patients are seen?
- $75,000
- $80,000
- $82,500
- $83,000 (Correct answer)
Correct answer: $83,000
C = 1,500(50) + 8,000 = 75,000 + 8,000 = $83,000.
