Managing fear associated with nursing in urban environments: first steps.

Improvement of the health of the nation demands that we prepare nurses to deliver care to those within our urban settings. Yet students frequently are uncomfortable visiting clients in urban settings. Our initial efforts were to refine the Environmental Comfort Scale (Carter, Carroll, & Hayes, 1994), an instrument developed to measure comfort levels in various urban scenarios. This article reports the results of this instrument refinement as well as the inductive process leading to the initial conceptualization of a model that addresses threats to safety. These threats, in turn, generate fear of nursing in community-based settings. The study participants were 120 volunteer junior students in a baccalaureate nursing program. The Environmental Comfort Scale II was administered to students at the beginning of an orientation session prior to their initial clinical nursing course. The instrument consisted of 15 items: 3 demographic items, 11 items asking students to rate their level of comfort and of fear in relation to various urban situations, and 1 open-ended question. Analysis of data led to conceptualization of two factors that could influence comfort levels in the urban environment. The first factor was personal-emotional (affective) and the second factor was cognitive (objective). The interaction and interdependency of these two factors led to the creation of a model.

Environmental safety preparation for community-based nursing educational experiences: measurable indices.

Cities, formerly the hub of cultural activities and entertainment, are now more often associated with crime statistics and poverty. Students' emotional comfort and safety must therefore be prime considerations in planning community-based nursing education. This study piloted an instrument that promises to be useful in labeling situations that affect an individual's comfort level in an urban setting. Questions that guided the study included: (1) Does the Environmental Comfort Scale (ECS) score vary with the respondents' residential zone (urban = 1, suburban = 2, rural = 3)? (2) Is the instrument (Environmental Comfort [Fear] Scale) reliable? A one-shot, one-group, pre-experimental design was employed. Participants were self-selected from a junior baccalaureate nursing class (N = 79) that was a predominantly suburban-bred, relatively privileged population. The ECS contained nine specific environmental-situation items that could be construed as potentially threatening to safety. Respondents were to indicate on a five-point Likert scale the extent to which they would be fearful in each situation; 1 = least fearful and 5 = most fearful. Findings showed practically no difference in responses by residential zone and suggest a need for item refinement and a need to lengthen the tool to improve alpha coefficients. Further, the increasing demand for measurable outcomes underscores the need for continued work on instruments to produce such data. The deinstitutionalization of health care from contained grounds to uncontained community-based settings makes it imperative that nursing education attend to the challenges of safety education.

School nursing in America--1902-1994: a return to public health nursing.

In October 1902, Lina Lavanche Rogers began her work in the New York City schools as the first school nurse in the United States. The purpose of this research was to examine the evolution of school nursing as it exemplifies development of a public health nursing specialty. Historiographic methodology was used. Primary sources included materials written by pioneers in school nursing. Secondary sources included journals, books, newspapers, biographical materials, and unpublished materials from the archives of health care and educational institutions and agencies. Public health nurses in 1902 had a model for practice that was considerably more independent and interdependent than that characterizing the practice of hospital nurses. From its origins in public health nursing, the role of the school nurse shrunk in many school systems to that of dispenser of bandages and aspirins, only to return once more to an advanced practice model. HIV, tuberculosis, sexually transmitted diseases, addiction, and violence have returned and/or replaced the contagious diseases of 1902 and the early years of school nursing. New immigrants, poverty, homelessness, and lack of primary care offer challenges to school nurses to meet the needs of schoolchildren and their families in the 1900s.

Attributional theory applied to a baccalaureate nursing community experience.

This study reports on the effectiveness of the attributional approach for evaluating outcomes of bicultural nurse-client interactions. Data for retrospective analysis were drawn from junior baccalaureate nursing students' (N = 16) self-evaluations of a one-to-one experience with a low-income, elderly, minority, urban resident. This data collection site, a wellness center in the resident/participant's high-rise apartment building, was ideal because of the relative control of variables that tend to raise caregiver anxiety and confound outcomes of nurse-client bicultural interactions in community-based settings. Faculty found the attributional tool to have major advantages involving the students' preconceived ideas and plans for person growth. Multicultural population trends and expanding community-based nursing practice needs make it imperative that barriers in bicultural situations be addressed.

Assessment of patient laboratory data in the acutely ill.

Laboratory test results are a valuable source of information. Nurses need to assess laboratory test results as part of the physical assessment of their patients. Comparison of laboratory test results and changes with abnormal physical findings provides the basis for changes in the nursing care plan. Progressive monitoring of laboratory results and prompt interventions might lessen the seriousness of the health problem. In acute care units, the initial group of laboratory tests serves as a baseline for assessing additional test results. Several reference values should be remembered, particularly the electrolytes (potassium, sodium, and calcium), glucose, BUN, creatinine, and albumin. Specific group profiles assist in identifying and in monitoring the patient's health status. Incorporating laboratory test results into the plan and evaluation of care will result in safer and more effective patient care. Referring to laboratory test findings and comparing them with physical assessment findings are required for the delivery of professional nursing care.

Suppression and regeneration of rat bone marrow under the influence of methotrexate. An EM study.

Adult male rats were given daily injections of methotrexate for 12 days, during which time specimens of femoral bone marrow were taken for correlative light- and electron-microscopic study. After 12 days methotrexate was discontinued and specimens were taken the marrow recovered from the effect of methotrexate. Normal rat bone marrow was used as a basis of comparison. As methotrexate was administered, cell division ceased and the immature erythroblasts and myelocytes proceeded in the maturational process and a rapid hypocellularity of the marrow developed. Eosinophilic leukocytes, lymphocytes, large fat cells, erythrocytes, and phagocytic reticuloendothelial cells were the only formed elements remaining after 12 days of methotrexate treatment. Two days after methotrexate was discontinued, myeloblasts, myelocytes and proerythroblasts were plentiful, and on the third day the marrow exhibited an erythroid hyperplasia. By the eighth day all cell types were present though the marrow still was hypocellular. 14 days post methotrexate the marrow returned to normal.
