Pharmacology connections to nursing 3rd pdf

This paper describes why case studies deserve a place in the centre of the bioscience curriculum, and how they have been used as a vehicle to improve care and save lives. A knowledge of drugs, their side-effects and pharmacology connections to nursing 3rd pdf is becoming increasingly important to nurses. One powerful way to convey this information is the case study, which, despite its limitations, has the potential to endow difficult topics in therapeutics with the power of the narrative.

The author suggests that case study projects encourage students to forge theory-practice links, related to their own specialist areas. They also provide rich qualitative data for evaluating and delineating the curriculum. 15 I such cases in the research project.

1997 Published by Elsevier Ltd. In this chapter, an attempt is made to describe the principal pharmacologic and therapeutic effects of the benzodiazepines and to correlate the experimental findings in animals with clinical observations in normal human subjects and patients with a variety of psychoneurotic, mental, and neurological disorders. Based on experience with chlordiazepoxide and diazepam, the first benzodiazepines introduced in clinical practice and the still limited observations with a number of newer analogs, it is shown that therapeutic efficacy and side effect liability can, in part, be directly related to the pharmacologic effects in normal animals or especially prepared animal models. For other clinical observations, however, the pharmacologic basis remains speculative. The comparison with other psychotropic agents provides further data that may shed some light on the significance of animal testing for the predication of the therapeutic value of psychotropic drugs.

The chapter represents an attempt to correlate on a broad basis the knowledge obtained in animal experiments with the clinical experience in human. It is clear that in the atmosphere of exploration and discovery that is always created by a new class of drugs, clinicians, and basic scientists usually tend to pursue their respective research goals without too much concern about the results of other disciplines. Drug effects on conditioned animal behavior, for example, are one of the areas where basic scientists have gained an enormous amount of data, but have not been able to correlate many of these results with clinically observed drug actions in human. The new and interesting findings on the maintenance of muscle tone through the interplay of the alpha and gamma motor neurons have greatly advanced the knowledge of motor reflexes and experimental induction of the spasticity of isolated muscles in cats. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. A number of non-infectious causes can result in diarrhea. These treatments have been estimated to have saved 50 million children in the past 25 years.

When people have diarrhea it is recommended that they continue to eat healthy food and babies continue to be breastfed. If commercial ORS are not available, homemade solutions may be used. 7 to 5 billion cases of diarrhea occur per year. Total deaths from diarrhea are estimated at 1. Secretory diarrhea means that there is an increase in the active secretion, or there is an inhibition of absorption.

There is little to no structural damage. It continues even when there is no oral food intake. Osmotic diarrhea occurs when too much water is drawn into the bowels. If a person drinks solutions with excessive sugar or excessive salt, these can draw water from the body into the bowel and cause osmotic diarrhea. High-fructose foods that also have a high glucose content are more absorbable and less likely to cause diarrhea.

Exudative diarrhea occurs with the presence of blood and pus in the stool. Inflammatory diarrhea occurs when there is damage to the mucosal lining or brush border, which leads to a passive loss of protein-rich fluids and a decreased ability to absorb these lost fluids. It can be caused by bacterial infections, viral infections, parasitic infections, or autoimmune problems such as inflammatory bowel diseases. It can also be caused by tuberculosis, colon cancer, and enteritis. The blood is a trace of an invasion of bowel tissue. Diarrheal disease may have a negative impact on both physical fitness and mental development.
