Evaluating practice through theories and models Essay - 3

Evaluating practice through theories and models - Essay Example This theory explains when nursing is needed and details how nursing can help in such a way that it appears to the patients as more supportive rather than invasive. As patients become inevitably unable to provide self-care, self-deficit takes place, and this is where the nursing support should come in. In Mr. Tan’s case, the ability to provide self-care is rather impracticable considering the physical limitations caused by his fifth leg amputation. At least, for self-care that requires lateral mobilization, it would be unfeasible for Mr. Tan to take care of himself. According to the Self-Deficit Theory, nursing comes in as an interactional reinforcement that functions to provide healthcare assistance to Mr. Tan. Looking at the situation, Mr. Tan is clearly unable to meet his own self-care requisites such as his universal self-care needs like promotion of normality and physical activities (Bernier 2002); without his wife’s or any other person’s help, he would be unable to serve himself with food, water, or medicine because of his leg amputation. This is where nursing is needed. Orem’s self-deficit theory is most applicable for Mr. Tan’s case because he is already incapable or limited in the provision of continuous effective self care; thus, he nee ds the following methods that Orem identifies as important to respond to this kind of situation: (1) acting for and doing for others: Mr. Tan needs a higher level of comfort and care; (2) Mr. Tan and his wife need guidance when it comes to controlling the disease and appropriate healthcare provisions, especially concerning his medications; (3) He needs support, not just physical but also emotional and psychological; and (4) he needs to be educated about his condition and he can control the degenerative effects of the Diabetes Mellitus to his body (Laferriere 1995 ). Mr. Tan displays a certain degree of hopelessness. His despondency over his condition has manifested in the way he deals with those that

Nutrition and fitness (answer the questions) - Essay Example While exercising, muscular endurance is essential because the continual pressure exerted on the muscles makes it possible to carry out heavy tasks without becoming tired. There exists a relationship between muscular strength and muscular endurance because one cannot exist without the other. Muscles occupy forty percent of body mass. The body depends on muscles for movement and because of this mass they are responsible for a portion of the metabolism that takes place inside bodies. Strong, well toned muscles help make work that had seemed difficult become easy to do and complete. To increase muscle endurance, an individual has to have strength in the muscles. This is because if a person has the strength, then building up endurance will happen rather quickly while a person with little or no muscle strength may take longer to increase muscle endurance. The continual exertion of force on the muscle with much heavier loads over a long period causes the muscle to harden and expand thus increasing the endurance level the muscle has to stress. This goes to show that muscle endurance goes together with muscle strength. This means that these two processes depend on each other for optimum results. Training teenagers is usually very difficult since they are impatient. This is usually very difficult since they work on gaining muscle endurance without first putting on muscle strength and want results in the quickest way possible. They use any avenue to get the results they need. This is usually very difficult since they work on gaining muscle endurance without first putting on muscle strength. Such actions lead to catastrophic results and injuries such as strains, sprains, dislocations, fractures and tendonitis. Further disregard may lead to other chronic complications, for example, nerve damage, bone stress injuries, muscle overloads and rotator cuff
