Needs Assessment For Implementation Of A Dedicated Admission And Discharge Nurse Position, Connie Ngo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Patient turnover refers to when patients are admitted, discharged, or transferred to or from a clinical unit or another facility. Rapid patient turnover compels nurses to provide care in an environment where clinical demands exceed nursing care capacity. The excess of clinical demands can lead to rationing of nursing care and culminate in nursing stress and dissatisfaction. These negative effects on the nursing workforce subsequently have undesirable implications for patient and hospital outcomes. Implementation of a dedicated admission and discharge nurse (ADN) position can optimize patient flow, improve nursing satisfaction, and ultimately promote positive patient outcomes. Purpose: The purpose …

By reasonably and fragmentarily using the elements of dodecaphony, sonorics, and aleatoric music, he developed his own musical language. Thus, the purpose of this work is to explore Shchedrin’s compositional style and to discover his innovation and individual style in the opera Boyarina Morozova. Shchedrin’s compositions are unusual: …

Increasing Swim Instructors' Perceived Knowledge Of Sensory-Based Strategies When Coaching Children Who May Have Sensory Differences, Gabrielle Palmer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although swim instructors are solely taught water safety regulations and correct swimming techniques, they are nonetheless viewed as mentors by the kids they work with. They are required to finish both their basic swim instructor (BSI) course and their cardiopulmonary resuscitation (CPR) certification, which primarily covers the fundamentals (American Red Cross Training Services, 2023; Kraft & Leblanc, 2018). However, neither provides a method of teaching swimming to children who might have sensory processing differences. This lack of education may affect both the child's participation and the swim instructor's capacity to impart knowledge. Research revealed that swim instructors are not very …

Plant-Plant Interaction In Early- Vs. Late-Successional Varieties Of The Hawaiian Landscape-Dominant Tree, Metrosideros Polymorpha, Tomoko Sakishima

UNLV Theses, Dissertations, Professional Papers, and Capstones

Plant-plant interactions play an important role in assembling plant communities. Interactions between neighboring plants can vary as a result of the genetic relatedness of neighbors, impacting rates of growth and patterns of resource allocation. When growing alongside close relatives, some species decrease their growth in a form of cooperation, while others grow faster through facilitation. A complication of plant interaction studies arises because decreased growth in the presence of close relatives can also be due to competition for resources, which increases with phenotypic similarity. Further complicating matters, mycorrhizal fungi, through their connections with plant roots, may strongly influence plant interactions. …

Evaluation Of An Emergency Department Provider Information Update On The Initiation Of Suboxone With A Community Treatment Program Referral For Opioid Overdose And Opioid Use Disorder, Carmen Brewington

All Dissertations

Over 21 million people in the United States (U.S.) require substance use disorder (SUD) treatment; yet less than 4 million people receive treatment (Bressan & Kening, 2023). According to Thomas et al. (2022), opioid overdose deaths are increasing, and improving access to evidence-based treatment is critical. Hospital emergency departments (EDs) play a lifesaving in the emergency treatment of opioid overdoses; but can also serve as gateways to opioid treatment by healthcare providers for opioid addictions (Reuter et al., 2022). Mortality, after an ED visit for opioid overdose, is high (Thomas et al., 2022). Community resources are limited, thus making it …

Effects Of Ferrite And Graphite Phases On Scratch Characteristics Of Nodular Cast Iron, Zhitong Xu, Ming Liu, Chenghui Gao, Fuqian Yang

Chemical and Materials Engineering Faculty Publications

In this work, we conduct micro-scratch tests of nodular cast iron with Vickers indenter under constant normal load and investigate the effects of individual phases (i.e., ferrite and graphite phases) on the scratch charac- teristics of nodular cast iron. Using a bimodal Gaussian model to fit the experimental data of penetration depth, residual depth, elastic recovery rate, and scratch hardness, we calculate the contribution percentages of indi- vidual phases to scratch variables. The scratch variables are independent of the scratch speed used in this work, while the penetration depth increases linearly with increasing the normal load. There exists a large …
