NOVA SOUTHEASTERN UNIVERSITY COLLEGE OF NURSING NUR 3180 SIMULATION DIABETIC KETOACIDOSIS Preparation Questions 1. Describe the pathophysiologic changes in DKA. The lack of available insulin results in a disorder in the metabolism of carbs‚ protein‚ and fat. Because they are attempting to rid the body of excess glucose‚ the kidneys excrete the glucose along with water and electrolytes (esp. sodium and potassium). The fatty acids are converted into ketone bodies by the liver. Ketone bodies are

Overall a sedentary individual is unconditioned and if they perform an activity more strenuous than they are accustomed to‚ they run the risk of a myocardial infarction from a higher oxygen demand on the heart that the body can not compensate for. An athlete is conditioned and the

Trisha was hospitalized briefly in her junior year of high school for exhaustion and dehydration. Hospital records note that she reported skipping meals to fit into a dress for a dance. Recent lab work shows that Trisha is moderately anemic. Her cholesterol levels are normal. Her average resting heart rate is 64 and her average resting blood

takes proper action to ensure the environment remains stable. All bodily structures fall under control of homeostatic mechanisms. Homeostatic mechanisms are controlled by two systems‚ the nervous system and endocrine system. The nervous system regulates homeostatic mechanisms by releasing nerve impulses in order to neutralize whatever change occurred. The endocrine system regulates homeostatic mechanisms by releasing hormones into the blood. When bodily changes take place‚ the nervous system tends

In these people rapid loss of body fluids leads to dehydration and shoal. Without treatment death can occur within hours.

‘Enteral nutrition (EN) refers to nutrients given via the gastrointestinal tract’ (GIT) (Crisp and Taylor 2009 pp.1154). EN is considered when an individual is not safe for oral intake or when oral intake is not adequate to meet nutrient requirements‚ for example when a patient is unable to swallow. Enteral feeding tubes may enter the body at a number of different sites‚ the choice of enteral feeding route depends on several factors such as the intended duration of the nutrition support‚ the patients

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. Anatomy: The branch of science concerned with the bodily structure of humans‚ animals‚ and other organisms‚ esp. as revealed by dissection. Physiology: The branch of biology that deals with the normal functions of living organisms and their parts. Anatomy and physiology are connected in

human body requires homeostasis to keep a set point at a constant. With feedback loops‚ the internal environment of the body can achieve to keep it at the set point. All homeostatic mechanisms use a feedback loop to inform the body about any changes that occur externally or internally. There are two different kinds of homeostatic mechanisms: a positive feedback mechanism and a negative feedback mechanism. Positive feedback mechanisms boost physiological processes and amplify the system’s action to
