1. Patient position – 30-45 degrees position. Head remain elevated for 30-60 mins
2. Patency of tube – Tube should be irrigated with water before and after each feeing to ensure patency.
3. Tube Position – Placement of tube is checked before each feeing or every 8 hours with continuous feeings. Checking methods; aspiration and pH.
4. Formula
5. Administration of feeding – feeing are given either by gravity drip method or by feeding pump.

Low Gi Diabetic Rice

...Low GI Diabetic Rice Diabetes Mellitus (DM) is one of the degenerative diseases which its prevalence continues to increase. Now Bangladesh ranked 10th in the world as a country with over 7 (seven) million diabetic patients and a growth of 5% - 6 % per year. The alarming fact is that over half the number of patients is still undiagnosed, though the disease can be controlled in around 70 per cent of the cases. Strict diet is often done to control blood glucose levels by reducing and even avoiding rice consumption because rice is considered as hyperglycemic food (can raise blood glucose level quickly) and replacing it with tubers. Whereas rice has a range of Glycemic Index value (GI), from low to high GI depending on the species and varieties. Rices that raise blood glucose level quickly have high GI levels, whereas with low GI will raise blood glucose levels slowly. Glycemic Index (GI) The number listed next to each food is its glycemic index. This is a value obtained by monitoring a person’s blood sugar after eating the food. The value can vary slightly from person to person and from one type or brand of food and another. A noticeable difference is the GI rating of Special-K which produced considerably different results in tests in the US and Australia, most likely resulting from different ingredients in each location. Despite this slight variation, the index provides a good guide to which foods you should be eating and which foods to avoid. The glycemic index range...

Brillo Feleycyl Joy Cruzada Angelo Jaiko Del Rosario Roevel Paul Quirao Jett P. Pastrana In partial fulfillment of the course requirements in Psychology 118 (Field Methods) Submitted to Mr. JOHNREV B. GUILARAN Division of Social Sciences College of Arts and Sciences University of the Philippines Visayas October 9, 2012 2 Leadership Identity Development: The Influence of Fraternity or Sorority Membership on College Student Leaders Fraternities and sororities began more than a century ago as relationship building organizations in which leadership development could be cultivated (Cory, 2011) but until recently, research found that fraternity and sorority membership may hinder student development and negatively impact the wellbeing of college students (Maisel, 1990; Wechsler, 1996). According to Kelly (2008) benefits of membership are realized by fraternity and sorority student leaders but struggled to refocus on their espoused values and mission: scholarship, service, leadership and relationships over the last several decades (Cory, 2011). Conversely, incidents of hazing, alcohol abuse, sexual assault, and substandard performance in the classroom, often overshadow the benefits of membership (Cory, 2011) suggesting that fraternal organizations have strayed from their traditional and founding values (Garret, n.d.; Maisel, 1990)...

Opioid Administration and Pain Management in the Terminally Ill Cancer Patient:

...Opioid Administration and Pain Management in the Terminally Ill Cancer Patient: Case study of a patient in the terminal phase of breast cancer. This case study is based on Ms. D, a 48-year-old married woman diagnosed with Bilateral Breast Cancer. She underwent a bilateral mastectomy 4 years ago. Lymph involvement was noted at the time of the surgery. Recent metastases of the bone has been diagnosed and she is in the terminal phase of the disease process. Up to this point, she has been on a regimen of Oxycodone 5 mg P.O. every 6 hours as needed for pain, Zantac 150mg P.O daily for heartburn, Docusate 100mg P.O. twice a day to promote bowel movements, Celexa 40mg PO daily for depression and enteric coated aspirin 81mg PO daily for prophylaxis of transient ischemic attacks and MI. She remains in her home and is receiving care at home. Ms. D has complained recently of significant increased pain and trouble sleeping, most likely due to the bone metastases in the area of the lumbar spine. She has stated that the pain has dramatically decreased her quality of life recently also. She has expressed the desire to remain at home during the terminal phase of her disease, but needs more adequate pain management to preserve her quality of life for as long as possible. She is married and her husband is very loving and supportive of her desire to stay in the home during this phase. He has voiced some concerns about drug dependency if the patient were to receive stronger pain medication...

...research conducted on John Evans Glacier, located about 80° N latitude. Graduating next semester with a B.S. in computer science and engineering and a minor in geographic information systems, I am interested in attending the University of Alberta for graduate study. Geographic information systems (GIS) is a field especially suited to investigating spatial patterns, modeling diverse scenarios, and overlaying spatial data. This semester, in my advanced GIS course, Spatial Data Structures and Algorithms, I am part of a team developing a temporal database and program for tracing historical trading data. My computer science skills have also been put to use in two summer internship projects, where I acquired proficiency with using LIDAR (light detection and ranging) technology, now favored by NASA in its current 10-year study of Greenland and changes in the ice cap extent. Through my coursework and project experience, I have also accrued skills in using Arc/Info, ArcView, Microstation, and RDBMS software packages, and I am equally comfortable programming in Visual Basic, C++, and Java. For my graduate research project, I would like to investigate methods for improving current GIS data models to better incorporate time as a variable in studying climate change. Changes in glaciers and polar environments occur rapidly, and...
