The new graduate in the operating room.

New graduate nurses today come to their first positions in nursing with varying knowledge bases and minimal clinical nursing skills. Gone are the days when new graduates begin functioning fully in a budgeted position on day one of employment. Mastery of psychomotor, cognitive, and affective skills necessary for nursing practice must be acquired through experience in the work situation. The more complex the clinical setting, the more stressful is the period of learning. The O.R. can be a highly stressful place. The need for anticipation, planning and organization to provide efficient care with meticulous attention to detail is coupled with the need to perform smoothly numerous technical skills. Safe, humanistic care cannot be implemented unless the nurse is also able to assess each patient's individual biopsychosocial status, and identify his unique nursing care needs. In order to learn to cope with this level of complexity, the neophyte nurse must be provided with a planned, supportive experiential learning situation that also provides the time necessary to achieve a beginning level of mastery. The program in Basic O.R. Nursing described here was one attempt to provide such an experience for new graduates.

Studies on the biochemistry of mitochondria and cell morphology in the neonatal swine hepatocyte.

Mitochondrial preparations isolated from neonatal swine hepatocytes show a marked increase in oxidative and concomitant phosphorylative capacity between birth and 2 days postpartum. There are no changes in the coupling parameters (respiratory control ratio and adenosine diphosphate/O ratio) with age. Changes in sedimentation properties in a sucrose gradient suggest qualitative changes in the mitochondria. Some of the lipid measurements (increased phospholipid) might be interpreted as supportive of this suggestion, although most could also be regarded as indicative of quantitative changes (increased number of mitochondria). Electron microscopy of isolated mitochondria and of the hepatocyte demonstrated an increased number of mitochondria but no change in shape, size, or structure as the pig developed. An increase in a number of cytoplasmic components (Golgi apparatus and endoplasmic reticulum) and a decrease in glycogen were also observed. The functional changes in mitochondria seem to occur within a short period of time (6-12 hr postpartum).
