In response, they recommend the D2D Model to increase the number of students in STEM. Onjira and Gilbert (2009) illustrate the affordances of machine-processable competency modeling. They argue that machine processing is invaluable in e-learning and assessment. They emphasize its effectiveness in e-learning. In addition, Onjira and Gilbert (2009) present the competency model’s affordances in generating questions, distractors, and adaptive query sequences. In the article, they conclude that using machine-processable competency overcomes many limitations in interoperability, reusability, and portability. They demonstrate the ease of automatically generating questions using templates. The system enables them to generate many questions from one template. They further argue that the presence of plausible distractors poses a challenge in generating multiple-choice questions. They conclude the article by looking forward to a future with an automated feedback system. Ricardo et al. (2009) explains the role of mathematics and statistics in the expression of scientific ideas. They conclude that mathematics and statistics are the languages of science. Because of the effect of the internet on learning approach of students, Ricardo et al. (2009) explored innovative ways of learning and teaching methodologies. They advocated acquisition of core competencies by students, development of relevant software and better methods of assessment emphasizing on higher-level abilities.

Management of Heart Failure Essay Example | Topics and Well Written Essays - 500 words

Management of Heart Failure - Essay Example Hypertension may lead to heart failure. It increases the heart’s workload hence results in hypertrophy of cardiac muscle fibers. The filling of the heart is impaired during diastole. The hypertrophied ventricle fails to contract eventually and heart failure results. The nursing intervention implemented to prevent cardiac failure in this case is the administration of the antihypertensive medication to control blood pressure and maintain it within normal for the hypertensive patient. Another condition that may lead to cardiac failure is myocardial infarction. It refers to the cellular and the necrosis of the heart muscle tissue and it is irreversible that occurs as a result of prolonged ischemia. The contractility of the muscle is lost in the affected regions. If the affected regions are large complications arise and include cardiac failure. The appropriate nursing intervention to prevent progression to heart failure is by ensuring that the patient gets enough rest, administrati on of stool softeners to prevent straining, and giving of analgesics and the prescribed medication as ordered. The nurse should also insist that the patient should quit smoking. It refers to the inflammation that occurs in the cardiac muscle as a result of viral infection in most cases. The nursing interventions that need to be implemented to prevent heart failure include the administration of the prescribed medication as ordered aimed at treating the condition for example the steroids to combat the inflammatory process.
