Purpose: To estimate real-environment iPod listening levels for listeners in 4 environments to gain insight into whether average listeners receive dosages exceeding occupational noise exposure guidelines as a result of their listening habits. Method: The earbud outputs of iPods were connected directly into the inputs of a digital recorder to make recordings of listening levels. These recordings were used to estimate listening levels using reference recordings made in a real ear. Recordings were made in 4 environments with a wide range of background noises: (a) a library, (b) a student center, (c) busy streets, and (d) the subway. Results: None of the 64 listeners were estimated to exceed allowable occupational dosages, with a maximum dose of 7.57% based on Occupational Safety and Health Administration (OSHA; 1998) methods and 10.83% based on National Institute for Occupational Safety and Health (NIOSH; 1998) methods. Conclusions: All of the listeners surveyed were exposed to dosages well below OSHA and NIOSH occupational regulations. Although this does not guarantee individual safety, the results do not support the widespread concern regarding the safety of common iPod usage. However, measurements made in this study agree with the finding that iPod output can exceed safe levels and further support recommendations to monitor and limit listening volume and listening duration.

KEY WORDS: noise, portable music device, iPod, OSHA, A number of studies have demonstrated that the maximum output levels produced by many portable listening devices, including tapes, CDs, and MP3 players, can exceed Occupational Safety and Health Administration [...]

INTRODUCTION: Restraints in the inpatient child/adolescent psychiatric population pose a threat to client safety and quality of care. Nurses are key in reducing restraints through implementation of evidenced-based interventions to improve quality and safety. AIM: To identify the impact of milieu nurse–client shift assignments on monthly restraint rates when compared with individual nurse–client shift assignments on an inpatient child/adolescent psychiatric unit. METHODS: A quantitative, retrospective, comparative project design was used. The sample included all inpatient child/adolescent clients admitted to the child/adolescent psychiatric unit between the months of January–May 2016 and 2017 who were physically or mechanically restrained. Retrospective chart audits were conducted, and information transcribed onto an adapted chart audit tool by Edwards et al. (2006). Monthly restraint rates were compared using the Mann–Whitney U test. A p value of <.05 was used to determine statistical significance. RESULTS: The Mann–Whitney U test revealed statistical significance between the impact that the individual nurse–client shift assignments (Mdn = 61.2, n = 6) and the milieu nurse–client shift assignments (Mdn = 6.8, n = 6) had on monthly restraint rates, U =.000, z = −2.88, p =.004, r =.83. CONCLUSION: Use of milieu nurse–client shift assignments are associated with lower monthly restraint rates when compared to individual nurse–client shift assignments. Milieu nurses provide structure, safety, consistency, and security, leading to early intervention and de-escalation of clients who display aggressive behaviors. Nurse staffing structures also need to be optimized to meet the needs of this population. [ABSTRACT FROM AUTHOR]
