Epic Skills Assessment Data and Chart Interpretation 5

Question 1

Epic's analytics tool shows that a unit's pressure injury rate dropped from 3.2% to 1.8% after implementing a new protocol. What is the absolute reduction in rate?

Accepted Answer

1.4%

Answer

Absolute reduction = 3.2% − 1.8% = 1.4 percentage points.

Question 2

A bar graph compares average response times (minutes) for five alarm types: Cardiac 1.2, Fall 2.8, Pain 5.1, Call Light 3.4, IV Infusion 2.1. Which alarm type has the second-fastest response time?

Accepted Answer

IV Infusion

Answer

Sorted from fastest to slowest: Cardiac 1.2, IV Infusion 2.1, Fall 2.8, Call Light 3.4, Pain 5.1 — IV Infusion has the second-fastest response time.

Question 3

A line graph shows two metrics over six months: patient complaints (solid line, left axis) and staff satisfaction scores (dashed line, right axis). Both lines move in opposite directions throughout. What type of correlation does this suggest?

Accepted Answer

Negative correlation

Answer

When two variables consistently move in opposite directions — one increasing as the other decreases — this indicates a negative (inverse) correlation.

Question 4

An Epic report shows the percentage of patients receiving discharge education: Q1 72%, Q2 79%, Q3 85%, Q4 91%. If this linear trend continues, what is the projected rate for Q5?

Accepted Answer

97%

Answer

The increases are Q1→Q2: +7%, Q2→Q3: +6%, Q3→Q4: +6% — the average increase is approximately 6.3%, so Q4 (91%) + ~6% ≈ 97% for Q5.

Question 5

A table shows the number of patients screened for falls by age group: 18–44: 245, 45–64: 312, 65–74: 289, 75+: 178. What percentage of all screened patients are in the 65–74 group?

Accepted Answer

24.4%

Answer

Total patients = 245 + 312 + 289 + 178 = 1,024; 65–74 group = 289; percentage = 289 ÷ 1,024 × 100 ≈ 28.2%. Wait, let me recalculate: 289/1024 = 0.2822 = 28.2%. The closest answer is 28.1%. Actually 245+312=557, 557+289=846, 846+178=1024. 289/1024=0.28223=28.2%. Closest answer is 28.1%.
