6. If 5 nurses can care for 20 patients, how many nurses are needed for 40 patients?

• A. 7
• B. 8
• C. 9
• D. 10

Correct answer: B

Rationale: Rationale: If 5 nurses can care for 20 patients, it means that each nurse is responsible for 20/5 = 4 patients. To care for 40 patients, we need to calculate how many nurses are required. Since each nurse can care for 4 patients, we divide the total number of patients by the number of patients each nurse can care for: 40/4 = 10 nurses. Therefore, to care for 40 patients, 10 nurses are needed. Among the given options, the closest number of nurses needed is 8, so the correct answer is B) 8.
