Outline and evaluate research into Stress and the Immune System Stress is the feeling of being under too much mental or emotional pressure, and is experienced when a person's perceived environmental, social, and physical demands exceed their perceived ability to cope. Stress itself is not an illness but can cause an illness if not tackled. By being stressed, it leads to an increase in cortisol (a hormone produced by the adrenal gland), and this increase in cortisol leads to a decrease in immune system functioning, which therefore leads to several illnesses. The main function of the immune system is to protect the body from infectious agents such as viruses and other toxins. In support of this theory, a natural experiment was carried out by Kiecolt Glasser et al in 1984.
The study was conducted on 46 women (mean age 31 years) recruited from one suburban midwifery practice and two obstetric practices in the northeastern United States. Participants underwent wrist actigraphy at home for 7 consecutive days to measure sleep quality. The Postpartum Depression Screening Scale measured depression severity. Women with postpartum depression experienced poorer sleep quality than women without postpartum depression. Sleep is very important for good health and especially for mothers who just gave birth.
A -- A carotid bruit #2 Due to Nancy's deteriorating condition she is referred to a neurologist. The emergency room nurse realizes that she has probably suffered from a left-sided brain attack. What clinical manifestation further supports this assessment? D -- Global Aphasia #3 What nursing intervention should the nurse implement when preparing Nancy for a noncontrast CT scan? B -- Explain that the client will not be able to move her head thoughout the CT scan #4 The neurologist also prescribes a magnetic resonance imaging (MRI) of the head STAT, why?
When stressed our immune system’s ability to fight off viral infections is reduced due to a decrease of white blood cells. This is known as immunosuppression, this occurs when the stress hormone corticosteroid is present from a stress response and lowers the number of lymphocytes such as B-cells and T-cells . Stress can have two types of effects, a direct effect or an indirect effect. The direct effect is when stress affects our health directly, for example, when stressed our digestive system is inhibited, after stress is gone, the digestive activity increases, this can lead to the occurrence of Ulcers in the stomach. Stress also increases the heart rate and can lead to the increase of blood pressure, thus Hypertension and can lead to Coronary Heart Disease (CHD).
Stress is defined as “the process by which we perceive and respond to certain events, called stressors, that we praise as threatening or challenging” (Myers, 2012, page 275). Stress is about an individual or is personal and is affected by the choices the person makes as an individual. The stress that is bad for you deprives you the ability to experience joy, happiness, enjoy life and who you are. That is why it is very important to recognize symptoms of stress and identify ways to bring the stress under control. The good stress is the kind that will help keep you motivated to be productive and be able to achieve the goals we set for ourselves.
They are educated for 1 year with clinicals and book learning, then "sit" for an exam. They *can* do everything a PCA, an NA, and a CNA does, but an LPN also administers SubQ injections, passes oral medications, takes vitals, and reports to the R.N. In the 1980s and 1990s, many USA hospitals tried to eliminate all NAs so the hospital could pay one pay rate and benefits (if any) for 1 person to do everything from personal care to medication passes. At the same time, many of these hospitals only wanted a B.S.N.-- a nurse who graduated with a Bachelors in Nursing. Hospitals used L.P.N.s for all the back-breaking work while (many) B.S.N.s did desk duty with charting and paperwork.
This weakens the immune system leaving the body vulnerable to infection and illness. Raised levels of cortisol suppresses the TH1 immune response. Kiecolt-Glaser et al conducted a natural experiment into acute stress, the aim was to see if the stress of exams had an effect on the immune system. Blood samples were taken from medical students before and during the exam period, T-Cell activity was measured in the blood samples. The findings showed that T-Cell activity was significantly higher before exams which suggests that acute stress caused reduced immune system functioning.
Hypertension and stress go hand in hand; stress has a direct effect on hypertension. Stress is the body’s reaction to any change that requires an adjustment or response. The body reacts to these changes with physical, mental, and emotional response. Most people give difference answers to what stress really is because it affects their body’s differently. What is stressful for one person may be pleasurable or have little effect on them and we all react to stress differently.
We also helped nurses in each floor if they had any questions about how to handle a patient with pressure ulcers. We also did many in services with new products to treat and prevent pressure ulcers. We monitored the pressure ulcers if they were community, hospital, or unit acquired and then, the manager of the Wound Care Program had to send all this information quarterly to the NDNQI, and if we found many patients with newly hospital acquired pressure ulcers the Wound Care Program manager and her team had to implement a plan with new ideas to lower the pressure ulcers in the floors, and to educate the nurses and techs in order to be more successful in prevention of pressure ulcers because the treatment can be
The area of the brain most affected by high stress is the hippocampus, which is very sensitive to cortisol. During the process of time, the cortisol will weaken the brain’s local memory and indexing systems and may narrow perceptual mapping (Jensen, 2008). For the distressed learner there can be so many reasons for their distress, from one’s own home, school to parents etc., anything that stresses the learner, this causes the brain to be on defense mechanism
