In a survey of night-shift hospital workers, those who reported fewer than five hours of sleep per 24-hour period committed medication-dosage errors at more than twice the rate of those who reported seven or more hours of sleep. Workers who reported fewer than five hours of sleep also worked, on average, 1.8 more shifts per week than those who reported seven or more hours.
Which of the following can be most properly inferred from these statements?
- Additional shifts, rather than sleep loss, are the true cause of the elevated dosage-error rate.
- The survey data do not isolate sleep duration as the sole factor behind the workers' higher error rate.
- Reducing shift load without changing sleep habits would lower the dosage-error rate for these workers.
- Workers who sleep seven or more hours never make medication-dosage errors during night shifts.
- The hospital's scheduling practices are the primary reason for the sleep deprivation among these workers.
