A study finds that nurses who sleep longer have fewer medication errors. Which conclusion is justified by this finding?
Correct answer: C. Sleep duration and errors are associated
- A. Longer sleep definitely prevents errors
- B. Medication errors definitely cause poor sleep
- C. Sleep duration and errors are associated
- D. The two variables have no relationship
Explanation
An association means that the variables vary together, but it does not prove that one causes the other. Workload, staffing, health, or other factors could influence both sleep and medication errors.
