In a study done by Willa L. Fields, it was determined that “there was no significant increase in difficulty of concentration...results indicated [though] that the 12-hour nurses were significantly more drowsy” (190). When nurses are drowsy on shift, they become less alert and oriented with their surroundings.As Linda Scott states in her article, “Inadequate sleep...contributes to loss of situational awareness and creativity, compromised problem solving decision making, and decreased alertness on duty further jeopardizing patients’ safety” (14). A study done by Deborah Martin was measuring the amount of sleep nurses get when working different shifts in a hospital. The data collected indicates that the mean amount of sleep per night for nurses working 8-hour shifts is 7.2 hours and the mean amount of sleep per night for nurses working 12-hour shifts was only 6.9 hours (84). Now that may not seem like much, but over time those hours add up, and fatigue levels, once again, will be on the rise. Nurses with bad sleeping patterns are more susceptible to chronic fatigue in the long run while they are already susceptible to acute fatigue in the present
