A hospital unit has a patient-to-nurse ratio of 5:1. If 3 nurses call out sick from a team of 12, how many patients can the remaining nurses handle?
Answer: 45
With 9 remaining nurses at a 5:1 ratio, the unit can handle 9 × 5 = 45 patients.
An Epic report shows that average claim processing time decreased from 4.8 minutes to 3.6 minutes. What is the percent decrease in processing time?

The decrease is 1.2 minutes, and 1.2/4.8 = 0.25 or 25%.
A billing department collected $1.2 million in Q1 and $1.44 million in Q2. If Q3 collections grow by the same percentage as Q1 to Q2, what will Q3 collections be?
Answer: $1.728 million
Q1 to Q2 growth is 20%, so Q3 = $1.44 million × 1.20 = $1.728 million.
A laboratory technician needs to dilute a 500 mL solution that is 40% concentration to a 16% concentration. How much diluent must be added?
Answer: 750 mL
Using C1V1 = C2V2: 0.40 × 500 = 0.16 × V2, so V2 = 1,250 mL, meaning 750 mL of diluent must be added.
An EHR system processes 3,600 transactions per hour. If system usage peaks at 140% of normal capacity, how many transactions per minute does the system handle at peak?
Answer: 84
Peak capacity is 3,600 × 1.40 = 5,040 per hour, which is 5,040/60 = 84 per minute.
A research team needs to enroll 450 participants across 6 sites. If Site A enrolls 22% and Site B enrolls 18% of the total, how many participants must the remaining 4 sites collectively enroll?
