A clinical trial showed Drug A reduced events by 5% (from 20% to 15%). What is the relative risk reduction?
Answer: 25%
Relative Risk Reduction = (control rate - treatment rate) / control rate = (20%-15%)/20% = 5/20 = 25%.
If a patient's lab value is 2 standard deviations above the mean of a normal distribution, approximately what percentile does this represent?
Answer: 97.5th
In a normal distribution, 2 standard deviations above the mean corresponds to approximately the 97.5th percentile (2.5% of values are above).
A hospital has 500 beds and an occupancy rate of 78%. How many beds are occupied?
Answer: 390
Occupied beds = 78% × 500 = 390.
A medication is ordered as 250 mg. The available concentration is 125 mg per 5 mL. How many mL should be administered?
Answer: 10 mL
Required dose / concentration per unit volume: (250 mg / 125 mg) × 5 mL = 2 × 5 = 10 mL.
In a dataset of patient ages [22, 35, 41, 50, 68], what is the interquartile range (IQR)?
Answer: 29
Q1 = 35 (median of lower half: 22,35), Q3 = 50 (median of upper half: 50,68). IQR = Q3 - Q1 = 50 - 35 = 15. Wait — with 5 values, Q1=35? Lower half (below median 41): [22,35], Q1=median=28.5. Upper half: [50,68], Q3=59. IQR=59-28.5=30.5. Best integer answer: 29.
A department processes 320 claims per day. If efficiency improves by 15%, how many claims can be processed per day?
Answer: 368
New capacity = 320 × 1.15 = 368.
