- C. $1.2
- D. $1200
Answer: B. $12
Rationale: The cost per patient day is calculated by dividing the total

per day).
2. During a clinical trial, a new drug was found to be 20% more effective
than the current standard medication. If the standard medication has a
success rate of 50%, what is the success rate of the new drug?
- A. 60%
- B. 70%
- C. 75%
- D. 80%
Answer: B. 70%
Rationale: A 20% increase on a 50% success rate is an additional 10%
(20% of 50), making the new drug's success rate 70%.
3. A hospital is trying to reduce its readmission rates. If the current
readmission rate is 15% and the hospital aims to reduce this by one-third,
what is the new target readmission rate?
- A. 5%
- B. 10%
- C. 12%
- D. 15%
Answer: B. 10%
Rationale: One-third of 15% is 5%, so reducing the rate by this amount

C. Hair color
D. Marital status
Answer: B. Height
Rationale: Height is a measurable quantity that can be expressed in

A. 10
B. 15
C. 20
D. 25
