Definition of Transthoracic Echocardiograph (TTE)- what it means?

Echocardiography is a non-invasive test that plays an essential role in the diagnosis and serial evaluation of many cardiac disorders. The impact of echocardiography in diagnosing cardiac abnormalities is imperative for health care professionals as it establishes specific problems into the general structure, function, motion of the heart and great vessels.

According to recent literature, Transthoracic Echocardiography is a common physiological diagnostic test which provides first suggestion into the presence of pulmonary hypertension in a patient presenting with unexplained dyspnoea, (the symptom experienced by Glenn).

Tranthoracic two dimensional echocardiography is a widely used technique for cardiac imaging, which will provide valuable information regarding the heart’s structural relationships, chamber sizes, wall motions and valvular functions specific to pulmonary hypertension. A transducer is used to perform a two-dimensional echocardiograph and is an effective method for evaluating physiological structures and function of the heart. It provides such images of the heart through standard parasternal long axis, parasternal short axis, apical four chamber, apical two chamber and subcostal views. In patients with pulmonary hypertension, the typical findings of right ventricular pressure overload on an echo include flattening of paradoxical motion of the interventriculaar septum, enlargement of the right heart chambers and increased thickness of the right ventricular wall.

The addition of Doppler Echocardiography is supplemented with TTE and records changes in frequency of sound waves. Doppler echocardiography is a method to detect the direction and velocity of moving blood within the heart. The changing frequencies are converted into an audible sound and shifted into a…...

...Carper, B. (2013). Fundamental patterns of knowing in nursing. In W. Cody (Ed), Philosophical and theoretical perspectives for advanced nursing practice (pp. 23-33). Burlington, MA: Jones & Barlett Learning. The author identifies the structure of knowledge and the fundamental patterns of knowing in nursing. It is in understanding these patterns that is essential for the teaching and learning of nursing. She describes what kinds of knowledge are held to be of the most value in the discipline of nursing. The four fundamental patterns of knowing she describes are: (1) empirics, the science of nursing, (2) esthetics, the art of nursing, (3) the component of personal knowledge in nursing, and (4) ethics, the component of moral knowledge. Understanding each of these patterns makes it possible for increased awareness of the complexity and diversity of nursing knowledge. She then goes on to say that each pattern may be necessary to achieve mastery in nursing but none of them alone should be considered sufficient. The patterns all work together, but one needs to understand each component to understand the overall concept. She then identifies three major significances to the discipline of nursing in distinguishing patterns of knowing, (1) the conclusions of the discipline conceived as the subject matter cannot be taught or learned without reference to the context of the structure; (2) each of the patterns represents one way of approaching the problems and questions of......

...Nursing Shortage and the Nurse to Patient Ratio Nursing Shortage Issues and the Nurse to Patient Ratio Throughout this paper the focus is going to be on nursing and how it is affected by a growing issue of shortages. The facility where I work has been affected by a nursing shortage; this is why I chose to focus on this topic. I have seen first-hand how everyone throughout the facility is affected by the shortage. I will talk about how the facility has handled the shortage as well as the type of structural organization that the company uses that has helped to keep it afloat. I have formed a null-hypothesis and an alternate hypothesis and formed an opinion based on my research. I hope to adequately inform you of all the issues surrounding the shortages. Since I work in a skilled nursing facility I will make it my main focus. Null Hypothesis: Shortages have not played a role in in-adequate care of others. Alternate Hypothesis: Shortages have played a role in in-adequate care of others. In today’s day and age women now have more career choices; back in the day it was common for women to become nurses, but now they can be just about anything. This affects the nursing field greatly. Not only do more career choices affect the nursing ratio, but an older and aging workforce is also part of the growing shortage. Some internal factors that I have noticed affecting the facility where I work is the......

... The Nursing Shortage Donna Burgess-Bingen Oklahoma City University Abstract Nursing is a very important part of healthcare. What can be learned through the research on the shortage of nurses? There is not just a shortage of nurses, but a problem with retaining nurses after they have graduated from school. Furthermore, how does the shortage effect nursing education. The Nursing Shortage Nursing is a crucial part of healthcare. Historically, nurses were at the bedside and monitored patients on a twenty-four hour basis. Nurses would collaborate with all aspects of the healthcare world in order to provide quality and efficient patient care. Today, the nurse’s role is continually changing with increasing responsibilities made complicated with the ongoing introduction of new-age technology. With so many recent changes and advances realized, it is not hard to imagine the predicated changes that are in store for the nursing profession in future years. Many mechanisms will come into play in the molding of nursing in the future, but a significant key component that could essentially inhibit the growth in the future of nursing lies in the impending nursing shortage. Will we be ready for this? Currently, worldwide research is being conducted in an effort to evaluate the cause of this looming challenge that we are currently facing and are likely to face in the future. Research has shown that the solution to this prolonged shortage is problematic in the sense that there are...

...most likely require rehospitalization. It is imperative for nurses to avoid jargons and use simple language to get the message across. While Henderson’s theory supports nursing as a profession in assisting patients who are well or sick and ensuring 14 basic needs, Orem’s theory is more contemporary where a nurse engages patient in plan of care and guides the patient to be self-dependent in the acquisition of knowledge and skills. Orem’s theory supports that client has the primary responsibility of personal health, with the nurse acting as a guide. Furthermore as long as self-care abilities equal or exceed self-care demands, such patients have no need for nursing ( Hohdorf,2010). However, if self –care deficit is recognized ,nurses should individualize care based on patient situation and must clearly communicate in order to improve and coordinate patient care. In order to improve and coordinate patient care, decisions made by nurses must be individualized to the patient situation, information collected by nurses must be clearly communicated to other health care providers and nurses must actively intervene and suppor Hohdorf, M.

...Philosophy of Nursing Why I Chose Nursing I chose nursing as my future profession because I believe nursing to be a rewarding and challenging career choice. I believe the desire to help people through nursing is a true calling, and I feel drawn toward helping those in need. I was first drawn to the area of professional nursing when my late sister became ill and was in the hospital for many months prior to her untimely death. This experience is what ultimately led me in the direction of pursuing a nursing education. Another reason I chose nursing is because the field offers a wide variety of career opportunities. A degree in nursing allows one to teach, conduct research, or perform direct patient care. I could elect to become an administrator, work in community or home health, and even travel worldwide. I can choose to work in childbirth centers, community health, emergency departments, geriatric wellness programs, intensive care units, mental health programs, occupational health, operating rooms, nursing research, school health, substance abuse treatment programs, and many more. With the national shortage of nurses, work schedules are flexible, pay is competitive, and openings are numerous. Jobs will be waiting for me the day after graduation anywhere in the world, and I will have a profession without additional training. The Core of Nursing Practice The core of nursing practice involves numerous factors that I believe to be of vital importance to being a great nurse....

...Nursing is a unique profession in that there are numerous different types of nurses, yet they can all experience the beginning of life as well as the end of life. Both nurses in addition to community-based nurses can yield special bonds with patients and their families. To me nursing is a very worthwhile profession and to become any type of nurse is an award within itself. This paper will converse how effective the communication in nursing practice will ease a mutually satisfying therapeutic patient nurse and their family relationship. Nursing is a challenging profession and requires critical thinking and good communication skills. With the baby boomers getting older the need for nurses is more than ever. No matter the setting whether it is in the hospital or in a community, nurses receive the same reward of helping people. Nursing has come a long way since Florence Nightingale and will continue to evolve well beyond into the future. Communication mainly requires the mindful utilization of the spoken word, and even though accounting for only fifteen percent of all interpersonal communication, is the major means of stating factual information in relations among nurse, patient and patient’s family. At the same time as communication is a vital part of building the relationship among nurse, patient and patient family members it is also just as significant among nurse and coworker. A virtuous relationship is good to quality patient care, obviously both nurse and coworker have......

...Highly Qualified Nursing Workforce Quality patient care hinges on having a well educated nursing workforce. Research has shown that lower mortality rates, fewer medication errors, and positive outcomes are all linked to nurses prepared at the baccalaureate and graduate degree levels. The American Association of Colleges of Nursing (AACN) is committed to working collaboratively to create a more highly qualified nursing workforce since education enhances both clinical competency and care delivery. This fact sheet looks at today’s nursing workforce; highlights research connecting education to outcomes; and outlines the capacity of four-year colleges to enhance the level of nursing education in the U.S. Snapshot of Today’s Nursing Workforce  According to the National Center for Health Workforce Analysis within the Health Resources and Services Administration (HRSA), approximately 2.8 million registered nurses (RNs) are currently working in nursing (HRSA, 2013). This count reflects an increase from the last National Sample Survey of Registered Nurses conducted by HRSA in 2008 which found that 2.6 million RNs were employed in nursing (out of a population of more than 3 million licensed RNs). HRSA’s 2013 report, titled The U.S. Nursing Workforce: Trends in Supply and Education, also found that 55% of the RN workforce held a baccalaureate or higher degree.

...Nursing, as described by the American Nurses Association, is the protection, promotion and optimization of health and abilities to prevent illnesses and injuries, alleviating suffering, through Diagnosis and treatment of human response and advocacy in care of individuals/family/communities and population. As nurses, we render care to our patients, recognizing that, as patients, they are always sick. We practice to treat, by protecting them from any further exposure that will prolong the illnesses. We promote good health by practicing infection control principles. Techniques, as the work, documented, from the pioneers, such as Florence Nightingale, our work is evidenced, by the continued decrease of hospitalization. By being educated as a nurse, we practice by using technologies learnt. As a result of the researches done, we gain that knowledge of how to prevent the spread of diseases, of how to prevent further illnesses. We promote wellness, by teaching the patients we serve, about the purpose of that particular medication. We teach and instruct them, on how the medication works, to help to cure the sickness, and the need to comply with the course of actions. Because of the knowledge gained, as a nurse to practice, we are able to help that patient, maintain their health, because, we are able to teach them that, that course of antibiotics, need to be taken for the full amount of days, even if they are feeling better.

...IOM Report on Nursing NRS-430V Lisa Arends October 11, 2015 IOM Report on Nursing Once the incorporation of the 2010 affordable care act came into existence this created a transformation within the healthcare industry. The affordable care act vision placed higher demands on patient healthcare needs that required more of nurses to be primarily involved with all aspects of patient care. This also placed more demands on nurses to become educated after they are licensed as a practicing nurse. The future of nursing was transformed to meet these demands through the Robert Wood Johnson Foundation alone with the Institute of Medicine which support nursing through focusing on nursing education. The IOM (Institute of Medicine) demands that nurses are to achieve higher levels of education and this training should occur through the educational system being improved.

BSN is said to mean Bachelors of Science in nursing or Baccalaureate Degree in Nursing. It takes between four and five years for one to get a bachelor's degree in nursing. Associate’s degree happens to be the list level of education that is needed to enter into the graduate program as of now as a result registered nurses are encouraged to earn their BSN. It is believed that BSNs degree nurse are offered more job opportunities than AND nurses and most time nurses with a BSN is said to earn between $3000 and $8000 more annually than a nurse with just ADN. Many experts are predicting that all registered nurses will be required to have a BSN in the near future. It has been found that nursing is now very competitive and many employers are seriously in need of nurses who stand out from the group with more qualifying and higher educational level to hire. A licensed practical nurse (LPN), registered nurse (RN), nurse practitioner (NP) are all referred to as nurses it is only their educational qualifications and expertise that differentiate them degree (Will 2015).

...unique position as a profession dominated historically by women means that while gender balance has been sought in professions once closed to women, nursing has made little effort to do the same. Men have equality of access, so it would be wrong to paint this as discrimination. But is that enough when there has been a failure to challenge the view of nursing as a woman’s job? Allied health professions have made strides towards equality, yet nursing still uses the titles ‘matron’ and ‘sister’. Archaic practices Even in training, archaic practices continue. One university restricts its best nursing student award to female students. Is it any wonder just 10% of UK nurses are men and many wards remain staffed entirely by women? Women make up 90% of nursing students. Is it right in 2016 for wards that treat male patients (in some cases exclusively) to have no male nurses? Is it truly patient-centred care to have a profession so far removed from its patient demographic? Every year across the UK women apply in droves to enter nursing, and the issues that put off their male counterparts are not being addressed. It is essential that male recruits are encouraged from an early age, and the outdated attitudes that stop men pursuing a career in nursing are challenged. Other professions have changed while nursing has rested on its laurels. Physiotherapy has gone from 5% men to 20%, and while in primary schools only 12% of teachers are men, one in......
