Increasing Nurses' Knowledge Of Advance Care Planning, Jocelyn K. Allen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Advance care planning (ACP) is a process that seeks to ensure patients receive medical care that is consistent with their values and preferences. The process has proven benefits for patients and their loved ones but is under-utilized in clinical practice. Nurses are capable of successfully supporting patients through ACP; however, they encounter barriers that prevent their engagement in the process. These barriers include a lack of knowledge regarding ACP, poor understanding of their role in the process, and a lack of confidence to embrace the practice.

The purpose of this DNP Project was to create an evidence-based educational intervention to …

Transitioning For Success: A Pilot Program For New Nurse Graduates In A Pediatric Intensive Care Unit, Valerie Charisa Barboa

UNLV Theses, Dissertations, Professional Papers, and Capstones

Global nursing shortages, increasingly complex patients, and rapidly evolving medical knowledge and technology make it necessary for today’s new graduate nurse (NGN) to enter practice with an already well developed set of skills (clinical judgment, technical skills, and a sound knowledge base). The protracted nursing shortage has prompted health care organizations to hire NGN’s directly into intensive care units (ICU), a rare, and previously unheard-of occurrence. Many NGN’s are unprepared for the highly complex, critically unstable patient in the ICU or the fast paced, independent, yet simultaneously collaborative nature of the ICU workplace. These deficits can quickly compromise patient safety …

Improving Type 2 Diabetes Mellitus In The Older Adult Population Utilizing Shared Medical Appointments In Primary Care Setting, Mailo Brantner

UNLV Theses, Dissertations, Professional Papers, and Capstones

The overall management of Type 2 diabetes mellitus (T2DM) and its comorbidities is complex and costly. The American Diabetes Association (ADA, 2019c) recommends the use of team-based care and self-management tools to optimize the management of T2DM. Unfortunately, there is a national shortage of endocrinologists and certified diabetes educators (Stewart, 2008) along with a primary care provider shortage (Simmons & Kapustin, 2011). Thus, it is essential to implement a care model to increase efficiency while also promoting patient knowledge and self-management of T2DM to improve health outcomes. An example of an innovative care model is the shared medical appointment (SMA), …

The Influence Of G4 Dna Structures On Stationary Phase Mutagenesis In Bacillus Subtilis, Tatiana Ermi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Until the late 1980’s it was widely understood that bacterial variance emerges randomly during growth. Research that followed has convincingly shown evidence for mutations arising in non-growing conditions, a phenomenon known as stationary-phase mutagenesis. In Bacillus subtilis, an elegant mutagenic mechanism has been elucidated in non-growing cells that biases mutations to transcribed regions of a subpopulation. One interesting possibility is that mutations can be further biased to hotspots within genes through alternate DNA structures known as non-B DNA. Non-B DNA have been linked to genomic instability and disease in humans, lesser is known about its role in bacteria. Here we …

Management Of Atrial Fibrillation With Smartphone Technology, Teresa Praus

UNLV Theses, Dissertations, Professional Papers, and Capstones

Atrial fibrillation is the most common arrhythmia affecting over six million people; it is predicted to increase two-fold by the year 2050. This arrhythmia results in a lack of

atrial/ventricular communication, accompanied by ineffective atrial contraction, suboptimal ventricular filling, and thrombus formation. This may lead to stroke, and ultimately heart failure. The current economic burden related to the complications of atrial fibrillation is estimated to be greater than $6 billion annually with potentially catastrophic events, further increasing expenditure.

When patients experience symptoms related to atrial fibrillation, it is common for them to present to a hospital emergency department. These visits, …

The Effects Of Somatosensory Input On Gait In Individuals Post-Stroke, Victor Hung, Amanda Reilly, Rachel Wood, Nikita Yuskov

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Stroke is a leading cause of disability that results in various neurological deficits, one of which is hemiplegia. This deficit alters the gait cycle, resulting in decreased propulsion force by plantar flexor muscles, decreased activation of dorsiflexor (DF) muscles, and increased coactivation of antagonistic ankle muscles. Stroke also leads to altered somatosensory input which results in decreased balance and gait speed, ultimately increasing fall risk. Therapies targeting increased somatosensory input have been shown to be beneficial in stroke as well as other neurological populations. However, no known studies have investigated the acute effects of local vibration to …

Exploring The Attitudes Of Students Enrolled In A Teacher Certification Program Through A Disability Awareness Documentary Film Intervention, Eunhye Choi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Negative attitudes towards individuals with disabilities can lead to a lack of opportunities in society as well as educational settings. Therefore, it is essential to promote positive attitudes to provide equal opportunities and rights to individuals with disabilities. However, there have been insufficient attempts to explore the attitudes of students enrolled in teacher certification programs. Diverse disability awareness programs have been utilized to enhance positive attitudes, and documentary films are frequently used to deliver such interventions. The current study implemented a series of documentary films as an intervention tool and examined the effects of the disability awareness documentary film intervention …

Hispanics And The War On Drugs: An Explanation For The Rise In Hispánica Imprisonment, Bryan James Haakma

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to understand racial disparities that persist throughout the criminal justice system. Since the early 1970s, the U.S. female prison population has risen at a faster rate than the male prison population (Harmon & Boppre, 2016; Morín, 2008, 2016). Overall, a plethora of research has linked the rise in imprisonment to the War on Drugs and the criminalization of drug use. This thesis examined these questions: 1) are drug crime initiatives driving the rise in Hispanic female imprisonment in comparison to Black and White females and 2) using Blalock’s (1967) theory on group threat, do …

Patients Enabled, Engaged, And Empowered: Implementation Of A Mobile Patient Engagement Technology, Jud Simonds

UNLV Theses, Dissertations, Professional Papers, and Capstones

Patient engagement technologies present an opportunity to enhance the patient experience by providing patient access to information throughout the entire, often complex, continuum of care. Growing evidence indicates that a lack of patient engagement is a significant contributor to preventable deaths. In contrast, engaging patients in their healthcare can positively affect patient outcomes and the overall patient experience. Unfortunately, traditional patient care models involve face to face patient-provider interactions, thereby limiting reach and impact. Exploring new roles for information technology (IT) within healthcare can contribute to addressing barriers encountered in more traditional healthcare models. Innovative IT solutions can assist patients …

Rapid Detection Of Toxin-Producing Cyanobacteria, Timothy Alba

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lake Mead provides drinking water to millions of people in Nevada, California, and Arizona. In 2015, the Southern Nevada Water Authority detected the cyanobacteria-produced toxin microcystin in the lake for the very first time. This toxin is lethal in large doses, and in small doses it causes a myriad of serious health effects. Detecting microcystin directly is a time-consuming and expensive process that requires liquid chromatography tandem mass spectrometry or immunological analyses, which require a full day or more to process samples. In order to provide water managers with the methodology for a toxin monitoring plan, this work developed a …

The Relation Between Positive Stereotypes, Negative Stereotypes, And Discriminatory Behavior Toward Hispanic And White Populations, Aileen Ynez Lovitt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research examining positive stereotypes has suggested a possible connection between positive stereotype endorsement and prejudice. This literature, however, has not investigated the relation between positive and negative stereotypes endorsement. Additionally, the combined impact of positive and negative stereotype endorsement predicting prejudice or discrimination has not been considered. Two studies were conducted to address the limitations in past research and gain a better understanding of positive stereotypes relating to behaviors toward out-group racial groups using Hispanic and White participants. Positive stereotypes endorsement was hypothesized to be positively associated with negative stereotype endorsement and was expected to increase the predicted power of …

Characterization Of Beryllium Ion Complexation In The Presence Of Biological Buffers Using Isothermal Titration Calorimetry, Guillermo Alexander Ramirez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Be2+ ion is a biologically active metal that is capable of binding to proteins and has been shown to affect various cellular processes. When treated with Be2+, certain cancer cells display cytostatic effects. GSK3β is a regulatory kinase involved in the β-catenin pathway that may be involved in producing these cytostatic effects when Be2+ binds to it. In order to determine binding parameters between Be2+ and GSK3β, isothermal titration calorimetry (ITC) can be utilized. However, titrations at physiological pH cannot be carried out due to Be2+ unique speciation at neutral pH ranges. Significant precipitation occurs at pH 6 and higher …

Respiratory And Perceptual Responses To High Intensity Interval Exercise In Obese Adults, Nicholas Andrew Ross

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Obese adults experience low lung volume breathing at rest and during exercise, which provokes ventilatory constraints and dyspnea on exertion. High-intensity interval exercise (HIIE) has emerged as an alternative to continuous exercise (CE); however, the effects of HIIE on lung volumes, ventilatory constraints and dyspnea on exertion have not been studied in obese adults and thus tolerability of HIIE remains unknown. Therefore, the purpose of this study was to examine the differences in respiratory and perceptual responses during HIIE versus CE in obese adults when compared with nonobese adults. Methodology: Ten healthy, nonobese (24.1 ± 6.2 yr., BMI: 23 …
