How does an understanding of the mechanisms of the heart help you in treatment of your patient regardless of the illness?
The heart is a muscular pump that keeps blood flowing through the vessels, sending oxygen and nutrients to all parts of the body, and carrying away unwanted carbon dioxide and waste products. Having an understanding of its functions and mechanism is essential for the care of the patient. Let’s take for example a patient with Left-sided Heart failure. Because blood is not pump out adequately from left ventricles, it backs up to the lungs causing dyspnea, tachypnea, and cough with blood-tinge sputum, progressing occasionally to pulmonary edema, a life threatening event. Recognizing initial signs can prevent harmful outcomes

The Rental Heart - Analysis

...base of something symbolic, with vivid descriptions? ‘The Rental Heart’ is a science fiction short story, which is about an unknown character. It is assumed that the story is takingtakes place way out in the future, since all authentic hearts are replaced by mechanisms in the story. The story focuses on the feelings of the main character – the main character is heartbroken. Also remember to write the title and writer of the text The story and the main character in the story are mysterious. We are not informed about anything other than the main character’s feelings. No name is introduced, no gender or age. The gender is hard to guess because of the variation of the lovers’ genders. The story is told in first person point of view and therefore it is very subjective in the descriptions. The needs for the main character, to do some specific tasks are emphasized in the story by repeating some phrases . This makes the story such more creepy and mysterious. It is not only the main character that w e do not get to hear any specific detail about. The setting and the time of the story are is not mentioned. We are only informed that the main character travels to an island, at a point, to escape from all the misery and pain from his/her past relationships.

Sigmund Freud believes that we finish developing behaviours in our adolescents while Erik Erikson believes that it is a lifelong process. One believes that we are born with certain behaviours and the other believes that they are developed by our social influences. Sigmund Freud Sigmund Freud started his career as a doctor treating neurotic patients with hypnosis and became famous for founding a new system of psychology called psychoanalysis, Snowden, R (2010). Freud believes that our behaviour is stemmed from our unconscious mind and that our forbidden behaviours only express how we feel such as the dreams we have and the slips of speech the Freudian slip. Sigmund Freud states that we are driven by the same basic instincts as animals such as primarily, sex and aggression and has many theories of human behaviour, from the psychosexual stages of development; Freud believes that this develops our personality and sexuality and is evident from birth...

How to Mend a Broken Heart

...How to mend a broken heart Going through a heartbreak can feel like being underwater when you need to breath. Mending a broken heart is not an easy quick process and can be time consuming. The person in this situation can feel there is no light at the end of the tunnel. A broken heart can be caused by one of many devastating occurrences or scenarios in life, such as the passing of a loved one, losing/not getting your dream job or the infamous breaking up with your significant other, which this essay will concentrate on. People build their lives with someone they trust and care for, and then, in a blink of an eye, it can be. This can leave most people angry and sorrowful, questioning themselves and possibly their future. Once a person has past the grieving stage and the hours of crying themselves to sleep, then this person must give themselves some “me time”. They must make time for themselves. People sometimes get caught up in a routine with their daily lives, especially after a break up. They should take a weekend and do things that make them happy, whether it’s hiking, biking, cooking or hanging out with friends that make them happy. Doing things that you love will not only distract a person from the heartache but can help a person realize they can be happy again. Writing down one’s feelings in a journal is a good coping mechanism. It can purify the mind through expression, thus resulting in happiness. Understanding and forgiving are major contributing factors in the...

...from potential clients seeking treatment for stress, anxiety, phobias and habits. It is essential for a therapist to understand the individual attributes of each one as well as understanding the relationship between these disorders. An understanding of the relationship between them allows therapists to decide which type of treatment will be most accurate as well as effective. In this essay I will start by defining stress, anxiety, habits and phobias and as well as exploring their individual attributes and symptoms I will seek to discuss the link between them as well as describing how I would treat these issues with hypnotherapy. Stress and Anxiety Are stress and anxiety just two different words to describe the same experience? Quite often they are coined together into one phrase because when you experience one you usually experience the other. This is not to say that they are the same. In fact, despite both states producing similar responses, there are differences in the triggers which cause them. Our bodies are designed to respond to danger; we have an inbuilt defence mechanism known as the ‘fight or flight response’, which triggers psychological and physical changes in our bodies.  The release of chemicals can give rise to very real physical symptoms such as the release of adrenalin, a rapid heart rate and breathing as well as heightened senses. These symptoms are designed to give us the ability to ‘fight or flee’ a specific danger. In evolutionary terms it would have been...

Alterations in Cardiovascular Function

...23: Alterations in Cardiovascular Function) A.O. was an 89-year-old woman with a long history of heart failure secondary to a large left ventricular infarct. She had poor activity tolerance and required assistance with activities of daily living. Even minimal activity was associated with moderately severe dyspnea and exertional chest pain, which was relieved by rest. A.O. also exhibited marked pedal edema bilaterally. She took digitalis, furosemide (Lasix), KCl, and sublingual nitroglycerin. Discussion Questions 1.Which type of heart failure (left or right sided) is usually associated with dyspnea? What other clinical findings are likely to be present with this type of heart failure? A.O. has left sided heart failure. Other clinical findings that present with left sided heart failure are pulmonary congestion and inadequate perfusion of the systemic circulation and symptoms include orthopnea, cough, fatigue and edema and decreased urine output. Pulmonary edema and S3 gallop (3rd heart sound) is present with the physical examination, as well as high or low blood pressure. An echo can show decreased cardiac output and a chest x-ray may show an enlarged heart (Huether & McCance, 2012). 2.What compensatory mechanisms are likely to be operative in A.O. to enhance cardiac output? The cardiac output is dependent on the heart rate and stroke volume. The factors that affect heart rate are the central nervous system, autonomic nervous system, neural reflexes, atrial receptors and...

...exposure. Going through a series of steps, your body consistently works to regain stability. With the general adaptation syndrome, a human’s adaptive response to stress has three distinct phases: ALARM STAGE - Your first reaction to stress recognizes there’s a danger and prepares to deal with the threat, a.k.a. the fight or flight response. Activation of the HPA axis, the nervous system (SNS) and the adrenal glands take place. During this phase the main stress hormones cortisol, adrenaline, and noradrenaline, is released to provide instant energy. If this energy is repeatedly not used by physical activity, it can become harmful. Too much adrenaline results in a surge of blood pressure that can damage blood vessels of the heart and brain – a risk factor in heart attack and stroke. The excess...

Stem Cell Research Paper

...traditions have adopted regarding this novel type of research. In several instances the religious traditions seem to have influenced the public-policy debates. There are many ways in which human stem cells can be used in research and the clinic. Studies of the medical use of Embyonic Stem cells will yield information about the complex events that occur during human development. A primary goal of this work is to identify how undifferentiated stem cells become the differentiated cells that form the tissues and organs. Scientists know that turning genes on and off is central to this process. Some of the most serious medical conditions, such as cancer and birth defects, are due to abnormal cell division and differentiation. A more complete understanding of the genetic and molecular controls of these processes may yield information about how such diseases arise and suggest new strategies for therapy. Predictably controlling cell proliferation and differentiation requires additional basic research on the molecular and genetic signals that regulate cell division and specialization. While recent developments with iPS cells suggest some of the specific factors that may be involved, techniques must be devised to introduce these factors safely into the cells and control the...

Theo 104 Reflection Paper 2

...Kaleb Parrent Mr. Seth Johnson Theology 104 3 April 2015 Reflection Paper 2 Assignment I. Introduction In today’s predominately secular culture, the doctrine of creation and the doctrine of the immaterial “heart” of man are topics too commonly misrepresented and are profoundly misunderstood amongst many Christians today. The doctrine of creation and the doctrine of the immaterial nature of man are fundamental cornerstones within the Christian worldview that promulgate a rational coherent, consistent doctrine that when properly taught can equip Christians today with important theological knowledge that facilitates their pursuit of effective ministry. Divided into two separate topics, I will subsequently expound upon the Christian doctrine of creation and the doctrine on the immaterial nature of man, outlining the theological definition, biblical foundation, and practical application for each. II. Doctrine of Creation a. Theological Definition The doctrine of creation propagates that an eternal, infinite and immaterial Triune God created ex nihilo, or out of nothing, the universe and everything within it. God created the “heavens, the earth, the fish, the various kinds of species of animals, and man as the crown of His creation” (Townes, Origin). This doctrine asserts that there was no preexistent material existed before creation, emphasizing God’s existence alone before creation, and affirming His infinitude, eternality, self-existence, self-sufficiency, omnipotence...

Stress Kills

...Understanding your limits Stress, Bottom Line up Front (BLUF), is bad for you. It can kill you, in fact. A recent study revealed that stress causes deterioration in everything from your gums to your heart and can make you more susceptible to everything from the common cold to cancer. Thanks to new research crossing the disciplines of psychology, medicine, neuroscience, and genetics, the mechanisms underlying the connection are rapidly becoming understandable. Stress begins with the perception of danger by the brain, and it appears that continued stress can actually bias the brain to perceive more danger by altering brain structures such as those which govern the perception of and response to threat. Prolonged exposure to cortisol inhibits the growth of new neurons, and can cause increased growth of the amygdala, the portion of the brain that controls fear and other emotional responses. The end result is heightened expectation of and attention to threats in the environment. Stress hormones also inhibit neuron growth in parts of the hippocampus, a brain area essential in forming new memories. In this way, stress results in memory impairments and impairs the brains ability to put emotional memories in context. Think of it this way: Too much stress and you forget not to be stressed out. These brain changes are thought by some researchers to be at the heart of the link between stress and depression one of stress s most devastating health consequences as well as posttraumatic...
