Metacognition is characterized as ‘knowing about knowing.’It can take many forms; it includes knowledge about when and how to use particular strategies for learning or for problem solving. Think about what your “muddiest point,” or confusion is about the course up to this point. 1) Post three ideas or concepts from the chapters assigned that you think are important. 2) Write one to two questions that you need answered before moving on to the second half of the course. 3) Respond to two other students’ questions.2.Millions of people work with computers every day. There is no single “correct” posture or arrangement of components that will fit everyone. However, there are basic design goals. Go to the following website:http://www.osha.gov/SLTC/etools/computerworkstations/index.html Consider your workstation as you read through each section and see if you can identify areas for improvement in posture, workstation components and placement, or work environment. Post your findings. Identify two other posts of interest and respond to each. 3.Review the following Case Study and answer the corresponding questions: Bursitis While home from college for spring break, 22-year-old Jennifer presents at her primary care physician’s office with pain and tenderness in the right shoulder. She reports the discomfort began two days prior to the office visit and right after her participation in a tennis tournament at school. The physician takes a careful history. During the physical examination she is able to point to an area of tenderness and slight swelling in the right shoulder. Both passive and active range of motion (ROM) of the right shoulder joint cause her considerable pain, particularly with the abduction of her arm. Except for the presenting symptoms, Jennifer’s history and physical are unremarkable. She expresses anxiety about what is wrong with her “tennis arm,” wondering what is causing the pain and how it can be remedied. The physician aspirates some bursa fluid from the right shoulder and administers a cortisone injection into the swollen bursae to reduce the inflammation; the aspirate is sent to the laboratory. He orders an x-ray of the shoulder. The initial diagnosis is non-infectious shoulder bursitis due to possible injury or overuse of the joint. Jennifer is advised to rest the joint and to use ice compresses. She is given a prescription for a mild pain killer and is scheduled to return for a follow-up appointment in one week. What are bursae?What is the probable cause of the bursitis in Jennifer’s right shoulder?Why is the aspiration procedure helpful in therapy and diagnosis?With good response to treatment, what is the probable prognosis for an uncomplicated bursitis?
