Nurses can take advantage of the Internet for information on diseases, diagnosis, and treatment, patient teaching, and collaboration with colleagues. The Internet is briefly described in this article. Several specific Internet addresses are given. Issues such as quality of resources, confidentiality and privacy, professional licensure and reimbursement of services rendered, and cost are discussed. Search tools for finding information you want on the Internet are included. 相似文献

The paper presents the data on morphofunctional changes in some rabbit organs (the liver, kidney, intestine, lung, heart) invaded with the nematode Passalurus ambiguus. The most profound inflammatory and dystrophic changes were found in the cecum which was a site of helminths. The signs of vacuolar dystrophy were also observed in the hepatic and renal parenchyma. There was activation of the immune system and mobilization of overall compensatory responses of the animals. 相似文献

The Amish are a conservative Protestant religious sect with a unique set of culture and traditions. In order to provide culturally appropriate and sensitive health care, it is imperative for nurses and other health care providers to have a basic understanding of variations of Amish lifestyle from other cultural groups. Application of Giger and Davidhizar's Transcultural Assessment Model provides information and nursing implications to assist nurses and other health care personnel when caring for Amish clients. 相似文献

Is elderly care nursing a specialty? This paper reports results from an interview-based study which aims to uncover the distinctive elements of nursing work with elderly people. Within the context of sociological literature on specialism it is concluded that a case for seeing elderly care nursing as a specialty area can be made. However, that case has implications for the continued marginalization of elderly people in society. 相似文献

A retrospective study was made of 35 periods of hospital admission between January 1985 and September 1995, of 17 patients diagnosed in the Hospital Josep Trueta, Girona, as having myasthenia gravis. These were all the patients diagnosed as having myasthenia gravis in this ten year period. We studied the characteristics of their stay in hospital and evaluated the planning and practice of nursing care during these 35 periods. Nursing problems or diagnostic difficulties were found on 15 occasions, probably due to lack of knowledge of myasthenia gravis. When a patient had dysphagia, nursing care was increased and any problems identified. 29.4% of the patients were admitted to the intensive care unit. Since this disorder may be very serious, we consider that special training should be given to the nurses attending these patients. An understanding of this disorder and the possible treatments, complications, drugs, etc. would make it possible to give specific, individualized attention which would result in a higher standard of care. 相似文献

Patients with obstructive jaundice suffer an increased incidence of mortality from post operative renal failure, which may be related to elevated circulating bile salts. This study assesses the effects of increased ionic strength (similar to that found in the kidney inner medulla) on bile salt critical micellar concentration (CMC) and cytotoxicity to renal medullary epithelial primary cultures and MDCK and NRK cell lines representing the distal and proximal tubular cells respectively. The CMC of chenodeoxycholic acid decreased from 2.86 +/- 0.07 (in isotonic Earle's Hepes buffer) to 2.30 +/- 0.07, 1.99 +/- 0.09 and 1.46 +/- 0.08 mM following the addition of 150, 250 and 500 mM NaCl. Similarly, the CMC of deoxycholic acid was reduced from 3.18 +/- 0.1 to 2.84 +/- 0.1, 2.26 +/- 0.1 and 1.79 +/- 0.09 mM by the addition of 150, 250 and 500 mM NaCl. Increasing the ionic strength of the culture medium of medullary epithelial cells by the addition of 150 mM NaCl, decreased viability by 39% (p < 0.01), 24% (p < 0.001) and 40% (p < 0.001) for lithocholic (25 microM), chenodeoxycholic (100 microM) and deoxycholic acids (100 microM), respectively. A similar increase in the ionic strength of the culture medium of MDCK cells decreased viability by 79% (p < 0.01), 46% (p < 0.01) and 15% (p < 0.01) for lithocholic (15 microM), chenodeoxycholic (100 microM) and deoxycholic (50 microM), respectively. Adding 200 mM urea to medium supplemented with 150 mM NaCl (to further increase osmolality but not ionic strength) had no effect on the cytotoxicity bile salts in MDCK cells. The addition of 150 mM NaCl to the culture medium of NRK cells resulted in a decrease viability of 15% (p < 0.01), 27% (p < 0.01) and 60% (p < 0.01) following exposure to either lithocholic (15 microM), chenodeoxycholic (50 microM) or deoxycholic acids (50 microM) respectively. These results show that increasing NaCl concentrations lowers CMC of bile salts and increase cytotoxicity in medullary epithelial primary, MDCK and NRK cells. This suggests that the high NaCl levels in the kidney inner medulla would reduce bile salt CMC such that they could damaged renal cells. This may, in part, explain the increased susceptibility of the kidney during obstructive liver disease. 相似文献

Determinants of subsequent home health care nursing service use by hospitalized patients with cancer
LS Yost R McCorkle K Buhler-Wilkerson D Schultz E Lusk 《Canadian Metallurgical Quarterly》1993,72(11):3304-3312
BACKGROUND: The authors examined the extent to which specific patient characteristics and length of hospital stay were capable of independently explaining the use of home health care nursing services by hospitalized patients with cancer after discharge. METHODS: The current study represents a secondary analysis of a data set originally gathered to identify the home health care needs of patients with cancer. The sample involved 87 patients with cancer who received home health care after hospitalization and 43 patients who did not receive such services. RESULTS: A logistic regression analysis indicated that home health care use was related to patient age, length of hospital stay, and level of symptom distress. Specifically, the likelihood of home health care use was found to increase among subjects older than 50 years of age, subjects with hospital stays of more than 7 days (apparently related to surgery), and those who experienced moderate to high levels of symptom distress. CONCLUSIONS: The results indicate a need for home health care nurses to be skilled in the management of cancer symptoms and in the complex problems commonly experienced by the postsurgical patient with cancer. 相似文献
