- Caffeine is a stimulant found in coffee, tea, soft drinks and other drinks and foods. After consumption, caffeine is absorbed into the blood stream and carried throughout the body and to the brain. In moderate amounts (~300 mg per day) it causes increased attentiveness, it reduces feelings of fatigue, and it enables most people to think clearly and concentrate for longer periods. Caffeine also increases heart rate and rate of respiration. In large quantities (>600 mg per day) its effects are magnified. People sometimes feel irritable, distracted and tense. People often use caffeine to increase mental alertness. Some people are more sensitive than others to the effects of caffeine. People who consume caffeine regularly may build up a tolerance to its effects. Further, since caffeine is mildly addictive, people who regularly consume caffeine may experience some withdrawal effects if they stop consumption. The Study In this study, three people each consumed varying levels of…John Wilkins, a 22-year-old male client, is diagnosed with seasonal affective disorder (SAD). The client lives in Oregon and it is winter time. The client stated he has no energy, feels depressed, and has recently gained 10 pounds because he only desires and eats items such as pastries, pasta, bagels, etc.He stated he does not want to leave his house and he stays in his pajamas all the time when he is off from work. He works in a factory and has no windows in the workplace. He said it is dark and gloomy when he leaves for work and dark when he comes home in the evening. He asks the LPN/LVN what he can do to manage the SAD. (Learning Objective10) a. How should the nurse describe SAD to the client and what is the treatment? b. What nursing management is needed for Mr. Wilkins?Which of the following is true about internal forces? Group of answer choices Come from the ground and other things the body is pushing on Cannot alter the movement of limbs Cannot cause a change in a bodies center of mass Can cause a change in a bodies center of mass must pick one answer only
- Watch this video (http://openstaxcollege.org/l/ emotions) to learn about physical responses to emotion. The autonomic system, which is important for regulating the homeostasis of the organ systems, is also responsible for our physiological responses to emotions such as fear. The video summarizes the extent of the body’s reactions and describes several effects of the autonomic system in response to fear. On the basis of what you have already studied about autonomic function, which effect would you expect to be associated with parasympathetic, rather than sympathetic, activity?Which of the following would cause muscle paralysis? An antibody that blocks nicotinic acetylcholine receptors A beta-adrenergic receptor agonist A serotonin reuptake inhibitor An acetylcholine esterase inhibitor NicotineWhat statement is true about painkillers. Group of answer choices Painkillers that reduce both pain and breathing are legal Painkillers that reduce both pain and breathing are illegal Painkillers that reduce both pain and breathing are ethical Painkillers that reduce pain and breathing are unethical
- Identify if the statement is True or False. If the statement is false, identify what is incorrect and correct it. The Endocrine system secretes regulatory hormones important for growth, reproduction and metabolism. The digestive system breaks down food, allows for nutrient absorption into blood and eliminates indigestible materials Extrinsic regulation results from activity of nervous system or endocrine system. In positive feedback the initial stimulus produces a response that reinforces the stimulusWhat must a body control system do to maintain homeostasis? Hint: outline the components of a feedback loop and their functionsWhich of the following best describes the sympathetic nervous system? i) Associated with stressful situations ii) Norepinephrine may be involved iii) Associated with voluntary responses i only O ii only Oi and ii only i and iii only O i, ii, and iii
- A negative feedback system is one in which a variable is changed in the same direction as the original change that initiated the system the initiating variable is always reduced (made more negative) a variable is changed in the opposite direction to the original change that initiated the system two opposing variables are played against one other the initiating variable is always increased (made more positive)Parkinson's disease causes tremors and slow movement due to the brain's inability to produce enough dopamine. Thus, to treat Parkinson's, doctors would MOST likely prescribe a dopamine: efferent. agonist. antagonist.Select all features of the nervous system. Uses neurotransmitters transported through blood Responses have a long duration effect Cannot act over long distances V Responses have a short duration effect Responses take a longer time Can have targets that are in distant locations in the body Has a rapid response time
