Hypertension - a contemporary approach to nursing care

The incidence of hypertension is increasing as the number of patients with obesity and diabetes mellitus increases. Hypertension results when the peripheral vascular resistance is increased, the blood viscosity is elevated and/or the flow of blood through the main arteries is impeded. Chronic hypertension results in enlarged heart, myocardial damage and lung and renal abnormalities. While some causative factors such as obesity can be controlled, others for example genetics are more difficult to treat because often there is more than one factor involved. This paper explores how essential and secondary factors contribute to the incidence of hypertension and the physiological changes resulting from raised blood pressure. It proposes that although traditional treatment has some success, nurse-led clinics are having better success not only in controlling raised blood pressure but also in reducing cardiac, pulmonary and renal morbidity. It is more cost-effective, staff is more productive and clients are more compliant with treatment.

Education and climate change – some systemic connections

Unlike most papers on education and ecology, this one is not concerned with the content of education but its organisation as a system and hence its purpose or finality. The central contention of the paper, which takes English education and training (or ‘learning’) as a case in point, is that in a new market-state formation the pursuit of short-term goals is tied to the global free-market economy over which any attempt at democratic control has been relinquished. At a time when humanity worldwide faces increasing change in the ecology that sustains it, this is considered to be ‘ecocidally insane’ and the opposite of any sort of learning from experience to alter behaviour in the future. The re-regulated new global market is seen in conclusion as a crisis response to the end of the previous Keynesian welfare nation-state formation. As such, it is argued to be unsustainable in any sense.
