Implications for bio-psycho-social-spiritual concerns in cardiovascular nursing.

One of the most challenging areas of scientific investigation is to determine the connections of the human spirit, emotions, love, attitudes, meaning, and purpose with physiologic and pathophysiologic alterations. Fundamental changes must occur in the current health care system and in research models so that cardiovascular patients, their families, and health care providers are presented with new strategies for prevention, stabilization, or reversal of the devastating effects of cardiovascular disease. The current biologic, unidimensional, reductionistic, technologic approach to the treatment of heart disease must be expanded to include the psycho-social-spiritual dimension. This article explores the mind-body dilemma, the theory and research basis for the psychophysiology of bodymind healing, and implications for practice and research.

Identifying critical defining characteristics of nursing diagnoses using magnitude estimation scaling.

The question addressed in this study was: Can the critical defining characteristics (CDCs) of nursing diagnoses be determined by magnitude estimation scaling (MES)? MES was used by having 32 nurse subjects numerically estimate the magnitude of each characteristic of anxiety and of sleep pattern disturbance on each of three concept dimensions: importance, frequency, and competency. Geometric means of the stimuli for each of the concept dimensions were computed and correlated with each other. Strong correlations between the characteristics and the concept dimensions were obtained. It was concluded that MES is a useful technique for identifying the CDCs and operational definitions of nursing diagnoses.

Effects of relaxation and music therapy on patients in a coronary care unit with presumptive acute myocardial infarction.

The purpose of this study was to determine whether relaxation and music therapy were effective in reducing stress in patients in a coronary care unit admitted with the presumptive diagnosis of acute myocardial infarction. In this experimental study, 80 patients were randomly assigned to a relaxation, music therapy, or control group. The relaxation and music therapy groups participated in three sessions over a two-day period. Stress was evaluated by apical heart rates, peripheral temperatures, cardiac complications, and qualitative patient evaluative data. Data analysis revealed that lowering apical heart rates and raising peripheral temperatures were more successful in the relaxation and music therapy groups than in the control group. The incidence of cardiac complications was found to be lower in the intervention groups, and most intervention subjects believed that such therapy was helpful. Both relaxation and music therapy are effective modalities to reduce stress in these patients.

Using magnitude estimation scaling to examine the validity of nursing diagnoses.

This paper describes the use of magnitude estimation scaling in the validation of the critical defining characteristics of nursing diagnoses. Magnitude estimation is a sensitive and accurate technique producing ratio level scales that offer advantages over ordinal level scales frequently used in validating nursing diagnoses. Magnitude estimation responses permit a consensus pattern to be achieved by producing stable and repeatable judgments to validate the importance of each sign and symptom investigated. Thus, magnitude estimation shows promise as a methodologic strategy for validating the critical defining characteristics of nursing diagnoses, thereby expanding the effort to identify and classify nursing phenomena.

Arterial blood-gas interpretations in the respiratory intensive-care unit.

The role of the nurse in the respiratory intensive-care unit requires increased sophistication as our knowledge of the patient becomes more complex. This expanded role should include a thorough understanding of disturbances in acid-base balance, the relationship of PaCO2 to ventilation, the difference in acute and chronic respiratory problems, and the causes and treatment of hypoxemia. The ability to analyze and evaluate blood-gas determinations is simply one more important tool the nurse may utilize in the care and treatment of the critically ill patient.
