Effects of cocaine, alone and in combination with task performance, on heart rate and blood pressure.
Eleven adult male subjects with histories of cocaine use participated in daily experimental sessions consisting of resting cardiovascular (heart rate, blood pressure) baseline measures followed by intranasal cocaine (4, 48 or 96 mg) administration and further cardiovascular monitoring. Subjects in Group I performed a learning task before and after cocaine administration, while subjects in Group II rested. Cocaine administration alone significantly increased heart rate up to 10 beats per minute (bpm) and mean arterial pressure (MAP) up to 15 mm/Hg. Task performance alone increased heart rate up to 8 bpm and MAP up to 10 mm/Hg. In combination, increases in heart rate up to 19 bpm and MAP up to 18 mm/Hg were observed. Thus, combinations of cocaine administration and task performance increased heart rate and blood pressure above levels observed following the occurrence of either activity alone. These results indicate the importance of understanding the effects of drugs within the environmental context in which they are taken.

Coping with hypertension.
Helping patients with hypertension achieve effective coping outcomes entails the implementation of multiple, autonomous nursing interventions specifically related to teaching and support. By teaching specific cognitive and behavioral strategies, the nurse assists the patient in developing effective means of incorporating the treatment regimen into a more healthful lifestyle. The supportive nursing actions help the patient make the necessary changes by providing the environment in which change may occur. As a result, the patient may reappraise the diagnosis of hypertension and its therapeutic regimen as less threatening and may consequently assume a more active role in its management.
Using a focus group to design a diabetes education program for an African American population.
PURPOSE: The purpose of this project was to determine what factors need to be considered in planning a diabetes education program to better meet the needs of African Americans with diabetes in a community served by a suburban community hospital. METHODS: Two focus group sessions were conducted. The sessions were recorded, transcribed, and analyzed by members of the research team. RESULTS: Four themes emerged that had bearing on program development: (1) a sense of personal powerlessness, (2) fear related to complications, (3) recognition of knowledge deficits accompanied by an inability to link behavior to outcomes, and (4) a clear vision of what kind of educational setting would interest and benefit the group. CONCLUSIONS: There were significant differences between what was being offered for diabetes education at the facility and what was desired according to the focus group, including factors of cost and leadership. Recommendations for future program planning are given.
