Implementation of problem-based learning in a final semester comprehensive nursing course.

Problem-based learning is a technique that is becoming increasingly popular in nursing educators in nursing education settings. In the 1980s, Knox and Mogan conducted classic studies on teacher effectiveness as rated by student nurses, graduate nurses, and faculty. They determined that nursing competence and teaching ability were highly rated by both students and faculty to "best" educators. Multiple studies utilizing problem-based teaching styles have revealed that students are highly satisfied with the results of certain characteristics, which promote student learning: self-directed learning, tutor-student interaction, and group learning. This article provides a review of the literature on problem-based learning in nursing education and specifically reviews articles utilizing the Mogan and Knox Nursing Clinical Teacher Effectiveness Inventory. Problems experienced in utilization of problem-based learning are also described.

Cardiovascular reactivity and the presence of pets, friends, and spouses: the truth about cats and dogs.

OBJECTIVE: The purpose of this study was to examine the effects of the presence of friends, spouses, and pets on cardiovascular reactivity to psychological and physical stress. METHODS: Cardiovascular reactivity was examined among 240 married couples, half of whom owned a pet. Mental arithmetic and cold pressor were performed in one of four randomly assigned social support conditions: alone, with pet or friend (friend present for non-pet owners), with spouse, with spouse and pet/friend. RESULTS: Relative to people without pets, people with pets had significantly lower heart rate and blood pressure levels during a resting baseline, significantly smaller increases (ie, reactivity) from baseline levels during the mental arithmetic and cold pressor, and faster recovery. Among pet owners, the lowest reactivity and quickest recovery was observed in the pet-present conditions. CONCLUSIONS: People perceive pets as important, supportive parts of their lives, and significant cardiovascular and behavioral benefits are associated with those perceptions.

The interrelationship between violence, HIV/AIDS, and drug use in incarcerated women.

The purpose of this study was to examine how violence co-occurs with drug use and HIV/AIDS high-risk behaviors among women incarcerated for drug use. This study was a supplement to a larger, experimental study designed to reduce HIV/AIDS high-risk behaviors among incarcerated female drug users. The women who participated (N = 170) reported that violence was a major part of their lives and affected many of their behaviors. Among these 170 women, 26.6% used condoms for oral sex, 46.4% for vaginal intercourse, and 65% were either sexually or physically abused. Intimate partner abuse was reported by 33.9% of the women. About 16% reported forced sexual activity, and 17.5% feared their partners. Women who refused to give oral sex to their male partners and those who insisted on condom use during oral sex prior to jail were more likely to be sexually or physically abused (chi 2 = 4.104; chi 2 = 3.886, p < .05, respectively). Although statistically significant interrelationships were not found among the three variables, significant bivariate relationships were found between intimate violence and HIV/AIDS high-risk behaviors.
