Epic Skills Assessment Quantitative Reasoning & Math Questions and Answers 2 — Questions and Answers
Question 1: A hospital reduces its average wait time from 45 minutes to 36 minutes. What is the percentage reduction?
- 20% (Correct answer)
- 25%
- 18%
- 22%
Correct answer: 20%
Reduction = (45-36)/45 × 100 = 9/45 × 100 = 20%.
Percentage reduction formula: (original - new)/original × 100. (45-36)/45 × 100 = 9/45 × 100 = 20%. Percentage calculations appear throughout Epic's analytics and performance dashboards — measuring improvements in wait times, readmission rates, and patient satisfaction scores.
Question 2: If a clinic sees 240 patients per week and is open 6 days a week, 8 hours per day, what is the average number of patients seen per hour?
- 4
- 5 (Correct answer)
- 6
- 8
Correct answer: 5
Total hours = 6×8=48. Patients per hour = 240/48=5.
Rate calculation: 240 patients ÷ (6 days × 8 hours/day) = 240 ÷ 48 = 5 patients/hour. This type of throughput calculation is used in Epic's scheduling analytics to set appointment slot durations and staff capacity planning.
Question 3: A medication dose is 0.5 mg/kg. A patient weighs 70 kg. What is the total dose?
- 35 mg (Correct answer)
- 70 mg
- 140 mg
- 0.7 mg
Correct answer: 35 mg
Dose = 0.5 mg/kg × 70 kg = 35 mg.
Weight-based dosing: 0.5 mg/kg × 70 kg = 35 mg. This fundamental pharmacology calculation is embedded in Epic's CPOE (Computerized Physician Order Entry) module, which auto-calculates weight-based doses when the patient weight is documented. Understanding this calculation is core to Epic medication management workflows.
Question 4: A department's budget is $500,000. If 60% is allocated to staff, 25% to supplies, and the rest to equipment, how much goes to equipment?
- $50,000
- $75,000 (Correct answer)
- $100,000
- $125,000
Correct answer: $75,000
Equipment = (100-60-25)% = 15% of $500,000 = $75,000.
Staff: 60%×$500K=$300K. Supplies: 25%×$500K=$125K. Remaining: 100-60-25=15%. Equipment: 15%×$500K=$75K. Budget allocation arithmetic is tested in Epic's quantitative section as it reflects revenue cycle and operational finance skills needed by analysts and administrators.
Question 5: Test sensitivity = 90%, specificity = 85%, prevalence = 10% in a population of 1,000. How many true positives are expected?
- 90 (Correct answer)
- 85
- 10
- 100
Correct answer: 90
True positives = sensitivity × actual positives = 90% × (10% × 1000) = 0.9 × 100 = 90.
Actual positives = 10% × 1,000 = 100. True positives = sensitivity × actual positives = 0.90 × 100 = 90. Understanding sensitivity, specificity, and predictive values is critical for evaluating clinical decision support tools in Epic, including diagnostic alerts and screening protocols.
Question 6: A hospital's length-of-stay data: 2, 3, 3, 5, 7, 7, 7, 10. What is the mode?
- 5
- 3
- 7 (Correct answer)
- 10
Correct answer: 7
The mode is the value appearing most frequently: 7 appears 3 times.
Mode = most frequently occurring value. Count: 2(×1),3(×2),5(×1),7(×3),10(×1). Mode = 7. In Epic's reporting, the mode of clinical measurements (like most common LOS, most frequent diagnosis code) helps identify typical patterns and outliers in population health management.
