The learning landscape continues to evolve as new technological tools enable teachers to deliver robust learning experiences. It is important to help teachers, administrators, and students know where to begin so that the transition to virtual learning is smooth, without educational loss. This chapter consists of two sections: current trends and issues in technology integration and technological pedagogical content knowledge. The first section briefly reviews the trends in instructional or educational technologies that are causing administrators, teachers, and students to reflect on and modify their thinking about learning and educational content delivery. The second section explores constructivism, the scientific underpinnings of nursing informatics, and ethics. Nurse educators must also address the ethical challenges brought about by this evolving learning landscape. After reading this chapter, one can understand current trends and issues, as well as the influence of nursing informatics and ways to approach new ethical dilemmas.

Healthcare is in a state of rapid change. Although practice environments have become more complex, educational delivery methods have remained stagnant. Innovative technologies provide opportunities to enhance nursing student learning and help nursing programs become more responsive to changes in the practice environment; however, obstacles may hinder successful implementation. With the increasing complexity of today’s health care environment, innovations in nursing curricula are necessary. This chapter explores some of the general challenges associated with the integration of innovative educational technologies, as well as some challenges unique to virtual simulation. It helps the reader to analyze the challenges of integrating educational technologies into nursing education associated with faculty, administrators, and students. It also helps the reader to examine practical and philosophical barriers related to technology integration and explores challenges unique to the adoption of virtual simulation.

Simulation has many advantages for nursing education, some of which include creating safe learning environments for students and reinforcing information learned in the classroom; it also has the advantage of being available in inclement weather as well as 24 hours a day for student access. Simulation in nursing is one of many methods used for teaching students. Teaching and learning in a virtual learning environment has many advantages for administrators, faculty, and students. One of the advantages includes the use of other disciplines to help create or participate in a virtual world learning experience. The virtual learning environment can be created to look similar to real communities, disaster areas, or homes, with avatars populating that environment. The advantage to using virtual reality, rather than a real-life experience, is that in real life, students could be immersed in an environment that could cause them harm.

This chapter shows the importance, for older persons, of support groups. In spite of the changes that have occurred in the American family, and all the negative things that fill the popular press concerning family relationships, the family is still the backbone of support for most older people. To some extent, the type of family support older people obtain depends on whether they are living in the community or in an institutional setting such as a group home, retirement village, or nursing facility. Whether a person is married, has great impact on that person’s support within a family setting including emotional, financial, and physical support, particularly in times of illness or infirmity. The success of a second marriage depends to a considerable extent on the reaction of the adult children of the elderly couple. Older grandparents, no matter how motivated, can find caring for grandchildren to be very tiring.

Delirium, also known as acute confusional state, organic brain syndrome, brain failure, and encephalopathy, is a common occurrence among medical and surgical patients and causes extensive morbidity and mortality. This chapter provides an updated review of delirium, including pathophysiological correlates, clinical features, diagnostic considerations, and contemporary treatment options. The defining features of delirium include an acute change in mental status characterized by altered consciousness, cognition, and fluctuations. The chapter explores the risk factors for delirium. These can be divided into two categories: predisposing factors and precipitating factors. Imbalances in the synthesis, release, and degradation in gamma-aminobutyric acid (GABA), glutamate, acetylcholine, and the monoamines have also been hypothesized to have roles in delirium. GABA is the primary inhibitory neurotransmitter in the central nervous system (CNS) and medications such as benzodiazepines and propofol have known actions at GABA receptors and have been associated with delirium.

This chapter shows how the United States and the world are experiencing an aging evolution we are growing older. America is going through a revolution. As a whole, Americans are becoming older, and there are many more older people among people than ever before in our history. Obviously all cohorts of the population youth, young adults, middle-aged, young-old, oldest-old are heterogeneous. When some people think about the elderly as a whole, they picture frail, weak, dependent persons, some in nursing homes and many confined to their homes. The chapter demonstrates the differences the various age categories have in relation to selected chronic health conditions that cause limitations of activity. Widowhood is much more common for elderly American women than for older men. The aging of Baby Boomers will solidify the shift America is experiencing with the aging of its population. Centenarians make up a small percentage of the total U.S. population.

Primary progressive aphasia (PPA) is the term applied to a clinical syndrome characterized by insidious progressive language impairment that is initially unaccompanied by other cognitive deficits. This chapter describes several variants of PPA and more than one etiology. It explains three main variants of PPA, namely, semantic Variant of PPA (svPPA), nonfluent/agrammatic variant of PPA (nfvPPA) and logopenic variant of PPA (lvPPA), and also describes criteria for their diagnoses. The defining symptom of PPA is the presence of a language impairment for at least 2 years in the absence of any other significant cognitive problem. Assessment of other cognitive domains is challenging because many tests of memory, attention, executive functioning, and visual-spatial skills rely on language processes in some manner. There are no drug therapies proven to arrest progression of signs and symptoms of PPA due to frontotemporal lobar dementia (FTLD) or Alzheimer’s disease (AD) pathologies.

Dementia is an umbrella term for conditions such as Alzheimer’s disease (AD), dementia with Lewy bodies (DLB), vascular dementia (VaD), and frontotemporal dementia (FTD). Under that umbrella, FTD, also known as frontotemporal lobar degeneration (FTLD), can be further categorized to define a group of neurodegenerative disorders resulting from a progressive deterioration of the cells in the anterior temporal and/or frontal lobes of the brain. More specifically, ventromedial-frontopolar cortex is identified with metabolic impairment in FTD. This chapter elaborates on the history, epidemiology, pathophysiology, clinical features, treatment, and outcomes of FTD. The history and background section of each of the FTD categories highlights the evolution of the disease conceptualization. The FTD subtypes are conceptualized in three categories: neurobehavioral variant, motor variant, and language variant. The chapter illustrates the features of all three categories of FTD.

The concept of Mild cognitive impairment (MCI) makes a lot of sense in that individuals are typically not “normal” one day and “demented” the next. In theory, especially for progressive neurodegenerative conditions, such as Alzheimer’s disease (AD), frontotemporal dementia (FTD), the development of dementia may take months or years. The clinical syndrome of MCI due to AD can be identified via a neuropsychological evaluation or less-sensitive cognitive screening measures. Much of what we are learning about MCI, and therefore refining its diagnostic criteria, is coming from two large-scale studies of cognition and aging: Alzheimer’s Disease Neuroimaging Initiative (ADNI) and Australian Imaging, Biomarkers and Lifestyle (AIBL). According to the most recent research diagnostic criteria for MCI due to AD, evidence of beta-amyloid deposition, neuronal injury, and/or other biochemical changes needs to be seen to increase confidence of the etiology of MCI. Cholinesterase inhibitors remain the primary pharmacological treatment for AD.

This chapter suggests that the dysexecutive syndrome associated with vascular dementia (VaD) is caused by impairment in separate but related cognitive concepts; that is, pathological inertia, mental bradyphrenia, disengagement, and temporal reordering. During the late 19th and early 20th centuries, cerebrovascular dementia was a well-established clinical syndrome. Multi-infarct dementia (MID) generally became associated with all types of vascular syndromes. Recent research suggests the presence of considerable overlap between the neuropathology underlying Alzheimer’s disease (AD) and VaD. Patients diagnosed with VaD tend to produce hyperkinetic/interminable perseverations, suggesting an inability to appropriately terminate a motor response. Other aspects of the dysexecutive syndrome associated with VaD revolve around constructs related to interference inhibition, flexibility of response selection, and sustained attention. From the view point of diagnosis, the neuropathology of VaD often differentially impacts the frontal lobes, whereas the neuropathology associated with AD revolves more around circumscribed temporal lobe involvement.
