Health Status Of Emergency Department Patients, Marjean J. Horning

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to help nursing develop a comprehensive care system for patients in selected emergency departments. To develop such a system, it was necessary to know the characteristics of and the health needs of that population.

The problem of this study was to describe the characteristics and health needs of patients in selected emergency departments.

Patients were interviewed using the Kisch Health Status Proxy (KHSP) and the Health Habits Inventory (HHI) as a guide. The KHSP listed acute and chronic conditions that an individual experienced. It gave a numerical score which rated the respondent in good, …

A Community Health Nursing Care Plan, Gayle Clark

Loma Linda University Electronic Theses, Dissertations & Projects

Structured nursing care plans are recognized tools in the effective utilization of the nursing process. Community health nursing services have not commonly used structured nursing care plans. The purpose of this study was to improve the management of patient problems through the deliberate use of the nursing process by providing the public health nurse with a structured nursing care plan. A plan was developed which consisted of a nursing history outline, a plan for action tool, and an evaluation form.

The nursing problem of milk anemia was selected to be managed by public health nurses in the study. Six nurses …

Post-Abortion Counseling And Anxiety Levels Of Unmarried Adolescents Having Therapeutic Abortions, Linda Levisen

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the effectiveness of a post-abortion counseling program. It was hypothesized that unmarried adolescents who received counseling following a therapeutic abortion would exhibit significantly fewer negative affects than those who received no counseling. The affects measured were anxiety, depression, hostility, and guilt. Twenty clients were randomly selected for this study. Prior to the abortion, the twenty clients were-tested for negative responses to the unwanted pregnancy. Ten clients received post-abortion counseling twice following the abortion and were tested at each visit for negative affective responses to the abortion. The other ten clients received no …

Patients' Reactions To Witnessing Cardio-Pulmonary Resuscitation, Lynn Andree Finch

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to describe the reactions to stress in patients witnessing a cardio-pulmonary resuscitation, in order to determine if the witnessing patients' needs are being met adequately, and to determine the effect of a specific psychological stressor on patients.

All resuscitations ("STATS") done over a two-month period at Loma Linda University Medical Center, with oriented patients in the room, were observed and recorded on an Observation Guide. A Questionnaire was also solicited from medical-surgical nursing personnel who had observed "STATS" with witnessing patients in the last three months. The Guide and the Questionnaire were developed from …

Assisting Mothers To Successfully Breast Feed Their Babies, Annabelle Moore

Loma Linda University Electronic Theses, Dissertations & Projects

This experimental study tested the effect of a teaching program on success of a group of mothers desiring to breast feed their babies. It was hypothesized that mothers receiving specific instructions on the physiology of lactation and the proper sucking technique would have greater success than mothers not so instructed.

To be categorized as successful the mothers had to have an adequate supply of milk and had to express satisfaction with breast feeding. Criteria for adequacy of milk supply consisted of weight gain of the infant within accepted norms without use of supplementary formula.

Twenty breast feeding mothers who delivered …

Sequential Analysis For Tolerances Of Noxious Weed Seeds, Seung Tokko

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The application of a sequential test, the sequential probability ratio test, for the tolerances of noxious weed seeds is studied. It is proved that the sequential test can give a similar power curve to that of the current fixed sample test if the test parameters are properly chosen.

The average sample size required by a sequential test, in general, is smaller than that of the existing test. However, in some cases it requires relatively a larger sample than current test.

As a solution to the problem a method of truncation is considered. A kind of mixed procedure is suggested. This …

Selecting The Best Linear Model From A Subset Of All Possible Models For A Given Set Of Predictors In A Multiple Linear Regression Analysis, David L. Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sixteen "model building" and "model selection" procedures commonly encountered in industry, all of which were initially alleged to be capable of identifying the best model from the collection of 2^k possible linear models corresponding to a given set of k predictors in a multiple linear regression analysis, were individually summarized and subsequently evaluated by considering their comparative advantages and limitations from both a theoretical and a practical standpoint. It was found that none of the proposed procedures were absolutely infallible and that several were actually unsuitable. However, it was also found that most of these techniques could still be …

A Two Sample Test Of The Reliability Performance Of Equipment Components, Miki Lynne Coleman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to develop a test which can be used to compare the reliability performances of two types of equipment components to determine whether or not the new component satisfies a given feasibility criterion.

Two types of tests were presented and compared: the fixed sample size test and the truncated sequential probability ratio test. Both of these tests involve use of a statistic which is approximately distributed as F.

This study showed that the truncated sequential probability ratio test has good potential as a means of comparing two component types to see whether or not the …

Selected Factors Related To Ability To Regain Bladder Function Following Indwelling Catheterization, Jongkolnee Padmasiri

Loma Linda University Electronic Theses, Dissertations & Projects

This exploratory retrospective study was designed to evaluate selected factors, including the ability to regain bladder function related to post indwelling urethral catheterization in an acute general hospital population.

The records of 107 patients who met the study criteria became the study population. These patients had three-way urethral catheters, continuous antibacterial irrigation and closed drainage system. Twenty patients died (19 percent) before the catheter was removed. Of the 87 patients who were alive, 37 percent (32 patients) had in-adequate bladder function. Of these 32 patients, no attempt was made to remove the catheter from 15 prior to their hospital discharge. …

A Clinical Comparison Of Six Orthodontic Techniques, Erik H. Madsen

Loma Linda University Electronic Theses, Dissertations & Projects

Controversy exists concerning the relative superiority of various orthodontic techniques because of the difficulties encountered in making comparative clinical studies of these techniques which are scientific and statistically meaningful. The purpose of this study was to clinically compare six different orthodontic techniques which are currently being taught, relative to a number of criteria, and to do it in a scientifically significant manner.

In order to eliminate as many of the irrelevant variables as possible, the patients were required to pass a relatively stringent screening to participate. Among other things, the patients had to have first molars in Class I relation …

Two Emotional Factors And Weight Loss Among Females Attending A Weight Control Class, Karen Lynn Carrigg, Eileen Rae Wangerin

Loma Linda University Electronic Theses, Dissertations & Projects

A descriptive study was conducted on twenty-four females attending a weight control class to discover the effect of weight loss upon levels of self-esteem and anxiety, as an understanding of the relation of these factors to reduction and control of weight would prove helpful to community health nurses in counseling with overweight and obese persons in the community.

The entire sample was tested for self-esteem (TSCS) and A-State and A-Trait anxiety levels at the initial class of the weight control program sponsored by the Health Education Department of Loma Linda University Medical Center, and again after seven weeks of class …

Some recent literature of interest is cited. The problem of ranking tied data is considered, and the effect of ties on the distribution of the signed rank statistic is examined.

A Review Of "Longitudinal Study" In Developmental Psychology, Emily H. Finley

Dissertations and Theses

The purpose of this library research thesis is to review the "longitudinal study" in terms of problems and present use. A preliminary search of the literature on longitudinal method revealed problems centering around two areas: (1) definition of "longitudinal study" and (2) practical problems of method itself. The purpose of this thesis then is to explore through a search of books and journals the following questions:

1. How can “longitudinal study” be defined?

2. What problems are inherent in the study of the same individuals over time and how can these problems be solved?

A third question which emerges from …
