The ability to engineer and precisely edit the genomes of animals, while potentially beneficial, has raised ethical questions. Paul Darrow—The New York Times/Redux Genetic engineering Genetic engineering, the artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules in order to modify an organism or population of organisms. Historical developments The term genetic engineering initially referred to various techniques used for the modification or manipulation of organisms through the processes of heredity and reproduction.

As such, the term embraced both artificial selection and all the interventions of biomedical techniques, among them artificial insemination, in vitro fertilization (e.g., “test-tube†babies), cloning, and gene manipulation. In the latter part of the 20th century, however, the term came to refer more specifically to methods of recombinant DNA technology (or gene cloning), in which DNA molecules from two or more sources are combined either within cells or in vitro and are then inserted into host organisms in which they are able to propagate. The possibility for recombinant DNA technology emerged with the discovery of restriction enzymes in 1968 by Swiss microbiologist Werner Arber. The following year American microbiologist Hamilton O.

Smith purified so-called type II restriction enzymes, which were found to be essential to genetic engineering for their ability to cleave a specific site within the DNA (as opposed to type I restriction enzymes, which cleave DNA at random sites). Drawing on Smith’s work, American molecular biologist Daniel Nathans helped advance the technique of DNA recombination in 1970–71 and demonstrated that type II enzymes could be useful in genetic studies. Genetic engineering based on recombination was pioneered in 1973 by 3/15/2021 Genetic engineering -- Britannica Online Encyclopedia American biochemists Stanley N. Cohen and Herbert W. Boyer, who were among the first to cut DNA into fragments, rejoin different fragments, and insert the new genes into E. coli bacteria, which then reproduced.

Process and techniques Most recombinant DNA technology involves the insertion of foreign genes into the plasmids of common laboratory strains of bacteria. Plasmids are small rings of DNA; they are not part of the bacterium’s chromosome (the main repository of the organism’s genetic information). Nonetheless, they are capable of directing protein synthesis, and, like chromosomal DNA, they are reproduced and passed on to the bacterium’s progeny. Thus, by incorporating foreign DNA (for example, a mammalian gene) into a bacterium, researchers can obtain an almost limitless number of copies of the inserted gene. Furthermore, if the inserted gene is operative (i.e., if it directs protein synthesis), the modified bacterium will produce the protein specified by the foreign DNA.

A subsequent generation of genetic engineering techniques that emerged in the early 21st century centred on gene editing. Gene editing, based on a technology known as CRISPR-Cas9, allows researchers to customize a living organism’s genetic sequence by making very specific changes to its DNA. Gene editing has a wide array of applications, being used for the genetic modification of crop plants and livestock and of laboratory model organisms (e.g., mice). The correction of genetic errors associated with disease in animals suggests that gene editing has potential applications in gene therapy for humans. Applications Genetic engineering has advanced the understanding of many theoretical and practical aspects of gene function and organization.

Through recombinant DNA techniques, bacteria have been created that are capable of synthesizing human insulin, human growth hormone, alpha interferon, a hepatitis B vaccine, and other medically useful substances. Plants may be genetically adjusted to enable them to fix nitrogen, and genetic diseases can possibly be corrected by replacing dysfunctional genes with normally functioning genes. Nevertheless, special concern has been focused on such achievements for fear that they might result in the 3/15/2021 Genetic engineering -- Britannica Online Encyclopedia  genetically engineered corn (maize) Genetically engineered corn (maize). © S74/Shutterstock.com introduction of unfavourable and possibly dangerous traits into microorganisms that were previously free of them—e.g., resistance to antibiotics, production of toxins, or a tendency to cause disease.

Likewise, the application of gene editing in humans has raised ethical concerns, particularly regarding its potential use to alter traits such as intelligence and beauty. Controversy In 1980 the “new†microorganisms created by recombinant DNA research were deemed patentable, and in 1986 the U.S. Department of Agriculture approved the sale of the first living genetically altered organism—a virus, used as a pseudorabies vaccine, from which a single gene had been cut. Since then several hundred patents have been awarded for genetically altered bacteria and plants. Patents on genetically engineered and genetically modified organisms, particularly crops and other foods, however, were a contentious issue, and they remained so into the first part of the 21st century.

Paper for above instructions

Introduction

The nursing shortage is a significant issue that has impacted healthcare systems across the globe, leading to compromised patient care, staff burnout, and increased operational costs. As the healthcare landscape evolves, the relationship between patient needs, resource allocation, and workforce management has become increasingly complex. This paper aims to explore competing needs within the context of nursing shortages in healthcare organizations by investigating policies that can help mitigate the challenges while promoting ethical considerations.

Competing Needs

Two significant competing needs impact the nursing shortage in healthcare facilities: the necessity for adequate staffing levels and the need for cost containment.

1. Adequate Staffing Levels

The fundamental need for adequate staffing in healthcare environments is critical for ensuring patient safety and quality care. Insufficient nurse-to-patient ratios directly correlate with adverse patient outcomes, increased mortality rates, and lower patient satisfaction scores (Needleman et al., 2011). When organizations face a shortage of nurses, the remaining staff may experience high levels of stress and burnout, which can lead to reduced job satisfaction and increased turnover rates (Perkins et al., 2020).

2. Cost Containment

On the other hand, healthcare organizations often find themselves in a constant struggle to remain financially viable. With rising operational costs, administrators may prioritize cost containment over adequate staffing. This can result in mandatory overtime, the use of unlicensed personnel, and reduced education benefits for nursing staff (Spetz et al., 2018). In attempting to manage budgets, healthcare leaders may inadvertently exacerbate the existing nurse shortage, creating a cyclical problem that affects patient care quality.

Existing Policies and Practices

In many healthcare organizations, common practices, such as mandatory overtime, serve as a double-edged sword in managing nursing shortages. While these practices may temporarily address shortfalls in nursing staff, they can lead to increased fatigue and job dissatisfaction among nurses (Graham & Lee, 2019). Employers often resort to measures like mandatory overtime to ensure that units remain adequately staffed while disregarding the detrimental long-term effects on staff morale and patient care.

Ethical Considerations

When evaluating the policy of mandatory overtime, it is essential to consider the ethical implications of such a practice. The American Nurses Association (2015) emphasizes the importance of nurse well-being and the duty to provide safe, quality patient care. Mandatory overtime can compromise these ethical obligations, placing undue burden on nurses and potentially jeopardizing patient outcomes.

Strengths of the Policy

The efficacy of mandatory overtime can be observed in the short term as it provides immediate solutions for staffing shortages and ensures that patient care needs are addressed. This practice can, at times, help in crisis situations, enabling facilities to meet the minimum nurse-patient ratio legally required.

Challenges of the Policy

However, the drawbacks of mandatory overtime are profound. Overworked nurses are at a higher risk of making clinical errors, which negatively impacts patient safety (Graham & Lee, 2019). Furthermore, this practice can lead to high turnover rates, increasing recruitment and training costs for organizations (Perkins et al., 2020). The long-term reliance on this policy can create an environment where qualified nurses choose to leave the profession due to burnout, exacerbating the very issues it seeks to mitigate.

Recommendations for Policy Change

To balance the competing needs of resources, workers, and patients, healthcare organizations must adopt comprehensive policy changes that prioritize nurse well-being while addressing staffing shortages and ensuring quality patient care.

Emerging Policy - Flexible Staffing Models

One effective policy change could involve the implementation of flexible staffing models that allow for more adaptable staffing solutions based on real-time patient care needs and nurse availability. For example, organizations could utilize innovative scheduling techniques that incorporate part-time staff, per diem nurses, and telehealth services to meet fluctuating demands (Spetz et al., 2018).
Healthcare facilities might also benefit from investing in nurse retention programs, such as offering educational support for furthering nursing credentials, which can improve job satisfaction and increase the availability of qualified staff (Perkins et al., 2020). Initiatives aimed at promoting a positive workplace culture, providing mental health resources, and implementing mandatory breaks can help reduce burnout among nursing staff, thus mitigating the shortages.

Ethical Considerations in Recommendations

These recommendations align with the ethical principles outlined by the American Nurses Association (2015), emphasizing the importance of protecting nurses' well-being and delivering quality patient care. By focusing on creating sustainable and ethical staffing solutions, healthcare organizations can improve both patient outcomes and nurse retention.

Conclusion

Addressing the nursing shortage requires a multidimensional approach that balances the competing needs of adequate staffing and cost containment. Existing policies, such as mandatory overtime, present numerous ethical challenges that can ultimately compromise patient care. By considering alternative strategies, such as flexible staffing models and robust retention programs, healthcare organizations can mitigate current workforce challenges while fostering a healthy work environment for nurses. Continued research and evidence-based advocacy are vital to ensure that nurse shortages are addressed ethically and effectively in future healthcare policy and practice.
