NURS 530 Assignment Video Presentation

The purpose of this assignment is to demonstrate understanding through teaching and explanation. Begin by choosing one of the topics below, or propose a topic of your own interest from the assigned readings subject to instructor approval. Post your choice to the discussion board thread “Video Presentation Topics” as soon as you make your choice. You may not select a topic that has already been chosen by a classmate. The sooner you choose, the more options you will have.

For this assignment, you will produce a 4–7 minute audio–video presentation on your chosen topic.

Record, Upload, and Submit

NURS 530 Assignment Video Presentationstates that the Kaltura Desktop Recording tool is available for free to WCU students to assist with recording video assignments. Another software or tool may be used to record your assignment. Completed videos are required to be uploaded to your Kaltura My Media area before they can be submitted in the Blackboard assignment area via Mashups Tool > Kaltura Media.

Kaltura Mashups Tool

In your presentation, include the following:

Include at least one type of visual aid in your presentation such as PowerPoint slides, diagrams, white board use, etc.

You are expected to explain the processes or concepts in your own words using references to support your explanations. Include a reference list at the end and cite references verbally or with on screen citations.

Thermoregulation is a self-regulating system that allows mammals to maintain their body temperature regardless of environmental temperatures. Temperature regulation is a form of homeostasis that allows an organism to maintain a constant internal temperature in order to survive. Endotherms employ thermoregulation to keep a relatively constant internal body temperature even when their external environment fluctuates, whereas ectotherms rely on their external environment for body heat. Endotherms include humans, other mammals, and birds. The usual core internal temperature of humans is roughly 37 degrees Celsius (98.6 degrees Fahrenheit), which can be tested most reliably with a rectal probe thermometer. This is the ideal temperature for the human body’s systems to operate at. Thermoregulation is essential for human survival; without it, the human body would stop working. Thermoregulation is also important in the body’s adaptive response to pathogenic infections. [1] [2]

The body’s core internal temperature has a small range, often ranging from 97 to 99 degrees Fahrenheit, and is tightly regulated. Overheating (hyperthermia) or being too cold (hypothermia) can occur when the body’s capacity to thermoregulate is impaired (hypothermia). Both states can have negative consequences for the body’s many systems, the most serious of which is diminished blood flow, which can lead to ischemia and multiple organ failure.

A fever can be caused by a viral infection or another infectious disease, elevating the core temperature above 37 degrees Celsius. Fever is caused by the release of pyrogens like cytokines, prostaglandins, and thromboxane by the body. These pyrogens cause arachidonic acid to be converted to prostaglandin E2 by cyclooxygenase 2 (COX2) (PGE2). The thermogenic set point is raised when PGE2 binds to receptors in the hypothalamus. The body works to reach a greater internal temperature as a result of the heightened temperature set point. [1] [3]

Go to the Development section.
according to NURS 530 Assignment Video Presentation the brain, primarily the hypothalamus, is in charge of temperature regulation. When the hypothalamus detects excessively hot or cold internal temperatures, it sends messages to the skin, glands, muscles, and organs. Afferent signals to the hypothalamus, for example, result in efferent signals to the skin cells to produce sweat if the body generates heat during high-level exercise or if the external ambient temperature is high enough to trigger an increase in the core temperature. Sweating is one way the body can employ to cool itself since sweat evaporation allows heat to escape. When the body is exposed to a chilly environment, the shivering reaction causes skeletal muscles to contract, producing heat; also, the arrector pili muscles (a kind of smooth muscle) elevate the hair follicles to trap the heat produced. [2]

Go to Organ Systems Involved for further information.
When thermoregulation is disrupted, it affects a variety of organs and body systems. Inadequate thermoregulation can cause many organ and system deficits during a heat-related disease. (Notice how many of these concerns are linked.)

NURS 530 Assignment Video Presentation states that As both heart rate and cardiac output increase, the heart is forced to more labor.
Intravascular volume depletion can occur in the circulatory system.
Ischemia and/or edema can occur in the brain.
As the intestinal mucosa becomes more permeable, the gastrointestinal tract becomes more vulnerable to bleeding and infection.
If ARDS causes prolonged hyperventilation, hyperpnea, and pulmonary vasodilation, the lungs become compromised.
Acute renal failure is caused by a loss of intravascular volume and poor circulation.
Fever, ischemia, and a surge in cytokines in the digestive system harm liver cells.
Microthrombi or DIC can cause ischemia in a variety of organs.
Electrolyte abnormalities, hypoglycemia, metabolic acidosis, and respiratory alkalosis are all possibilities.
The body’s systems are also harmed when body temperatures are severely reduced in hypothermia. Dysrhythmias, such as ventricular fibrillation, can affect the cardiovascular system. The electrical activity of the central nervous system (CNS) is noticeably reduced. Cold diuresis and noncardiogenic pulmonary edema can both occur. Hypothermia also causes preglomerular vasoconstriction, which lowers the glomerular filtration rate (GFR) and reduces the flow of blood to the kidneys (RBF). [3]
