Inhibition of transformation in group H streptococci by lysogeny.

Group H streptococcal strains Challis and WE4 were lysogenized with a bacteriophage isolated from strain Channon, after which their capacity for transformation to streptomycin and rifampin resistance was reduced by three orders of magnitude. The probable reason is the inability of the lysogenized strains to bind deoxyribonucleic acid irreversibly, even though they exhibit earlier stages of competence development during a competence regimen.

Building RN confidence for delegation decision-making skills in practice.

Delegation and coordination of patient care challenge registered nurses (RNs) practicing in capitated, managed care environments. Complicating the RN role is the fact that most RNs were not taught delegation skills while in nursing school. This study addressed the effect of a structured teaching intervention on RN delegation decision making and its enhancement of knowledge and confidence in delegation to team members. The intervention significantly increased RN delegation knowledge and overall confidence in decision making. Teaching strategies are explicated for staff development educators who are charged with providing substantive leadership approaches for staff and management nurses who have been out of nursing school and in the practice setting. The role of the RN in directing the workforce has become increasingly complex in capitated, managed care systems.

Cerebrovascular status of severe closed head injured patients following passive position changes.

Nursing care of the severe closed head injured patient has two primary goals: (1) the prevention of secondary brain injury associated with intracranial hypertension, and (2) the prevention of complications associated with immobility. This study examined the effects of six body position changes, performed as part of routine nursing care interventions, on the cerebrovascular status of 18 severely head injured patients. These changes included turning and positioning in bed, head rotation, range of motion exercises, and raising and lowering of the head of the bed. All subjects had baseline mean intracranial pressures of less than or equal to 15 mm/Hg, and cerebral perfusion pressures of greater than or equal to 50 mm/Hg. Over 200 observations of the effects of position changes on heart rate (HR), mean arterial blood pressure (MABP), mean intracranial pressure (MICP), and cerebral perfusion pressure (CPP) were recorded and analyzed. With the exception of the intervention raising the head of the bed, all position changes produced increases in HR, MABP, MICP, and CPP. Typically, the physiologic changes were transient and showed recovery toward baseline values in one-minute postintervention measurements. The results of this study suggest that passive position changes may be performed safely upon severe closed head injured patients with baseline MICPs less than or equal to 15 mm/Hg, provided CPPs are maintained above 50 mm/Hg throughout each position change and provided multiple fractures do not preclude these position changes.

Resources for graduate education: a report of a survey of forty states in the Midwest, West, and Southern regions.

This article data on the need for doctorally prepared nurses and the resources for their preparation in 40 states in the Midwest, West, and South. A mailed questionnaire was used to collect data from the administrative heads of 58 graduate nursing education programs. Results reported in this article are on: nursing faculty responsibilities, projected faculty needs, research supports for faculty, sabbatical leaves granted nursing faculty, research and interdisciplinary activities of nurse faculty, numbers of nurse and non-nurse doctorally prepared faculty, reported criteria for and difficulties in recruiting doctoral nurse faculty, initiating change in graduate nursing education and the reasons for change, the research requirements in master's nursing programs, and the reasons cited for establishing doctoral nursing programs within the 40 states. Questions that educators face in the development of quality programs of doctoral nursing education are discussed.

Sleep-awake patterns following cerebral concussion.

This study compared sleep-awake patterns in clients following head injury with their sleep-awake patterns prior to head injury. Data were collected from 75 subjects who had experienced a minor head injury (MHI) with a disturbance in consciousness three months prior to filling out a questionnaire. The majority of the clients were males, 16 to 30 years old, who had been involved in a motor vehicle accident which resulted in MHI. Questions related to the sleep-awake patterns before and after head injury. Sleep-awake patterns following head injury differed from sleep-awake patterns prior to head injury in the following sleep indicators: sleep interruptions per week and per night increased significantly (p less than .004, p less than .001) as did the time needed to function at peak efficiency upon awakening (p less than .001). The subjects reported significant increases (p less than .02) in the number of times per month in which they were unable to return to sleep after an early morning awakening coupled with the difficulty in returning to sleep (p less than .04). Overall, the clients reported significantly decreased sleep quality (p less than .02) and increased complaints about sleep following head injury (p less than .001). An increase in the time of consciousness disruption following head injury was related to the subjects having a tendency to sleep longer and to recall fewer, less vivid dreams. A decreased level of consciousness upon admission to the emergency department at time of injury correlated with the increased number of arousals during the sleep cycle and the reduced intensity of auditory stimulus needed to interrupt sleep. The anatomical site of the head injury and the duration of post-traumatic amnesia (PTA) were found to have no significant effect upon sleep-awake patterns following MHI.

Delegation skills and nurse job satisfaction.

In this study, the mean age was 41 and these nurses had been out of school for approximately 13 years. Over half of these RNs had never been taught delegation skills in nursing school. Of those who were exposed to the concept of delegation, their skills were not adequate to meet the patient care demands in the restructured health care system. During these challenging periods in health care, it is imperative that nursing service administrators provide RNs with the continuing education necessary to develop delegation strategies to adapt to their evolving professional roles. Continuing education classes on delegation skills are requisite for RNs practicing in a competitive managed care environment. As we approach the year 2000, the economic climate will dictate that RNs be skilled not only as clinicians, but also as leaders of the health care team. The findings of this study support that delegation decision-making skills enhance job satisfaction in the areas of decision making and promotional opportunity. Delegation knowledge is crucial to the successful direction of the health care team in the managed care environment.
