Question 1

A hospital treats 240 patients per week. If 35% are emergency cases, how many are non-emergency patients treated per week?

Accepted Answer

156

Answer

65% are non-emergency (100% − 35%), and 240 × 0.65 = 156 patients.

Question 2

A clinical study reports a mean recovery time of 8 days with a standard deviation of 2 days. What is the coefficient of variation (CV)?

Accepted Answer

25%

Answer

CV = (standard deviation ÷ mean) × 100 = (2 ÷ 8) × 100 = 25%.

Question 3

A pie chart shows hospital bed distribution: Surgery 30%, Cardiology 25%, Oncology 20%, Pediatrics 15%, Other 10%. If the hospital has 400 beds, how many are in Cardiology?

Accepted Answer

100

Answer

25% of 400 beds = 400 × 0.25 = 100 beds in Cardiology.

Question 4

A patient's white blood cell count (×10³/μL) over 4 weeks: Week 1: 4.5, Week 2: 6.2, Week 3: 5.8, Week 4: 7.5. What is the mean count over this period?

Accepted Answer

6.0

Answer

Mean = (4.5 + 6.2 + 5.8 + 7.5) ÷ 4 = 24.0 ÷ 4 = 6.0 ×10³/μL.

Question 5

A medication causes a side effect in 3 out of every 25 patients. In a group of 300 patients, how many would be expected to experience this side effect?

Accepted Answer

36

Answer

(3 ÷ 25) × 300 = 0.12 × 300 = 36 patients expected to experience the side effect.
