A patient comes to your office and asks you what carbon monoxide poisoning is. How do you answer? What are the symptoms? On the basis of what you have learned about the process of respiration, what is happening at the cellular level?© BrainMass Inc. brainmass.com October 25, 2018, 9:12 am ad1c9bdddf
When responding to the patient who is asking about carbon monoxide poisoning you should begin by telling them about carbon monoxide (CO). For instance, you can explain that it is a colorless and odorless gas that is toxic. You should also explain that that carbon monoxide poisoning is a result of the gas building up in a home, workplace, or other closed environment. This build up of gas can be due to a gas appliance that is not functioning properly or from improper venting of a gas appliance, stove, or fireplace (CDC, 2013). You can learn more about risks factors for carbon monoxide poisoning from the CDC or OSHA websites that are included in the reference list.
In order to list the symptoms of carbon monoxide poisoning, you should use a trustworthy and reliable medical ...
Carbon monoxide (CO) is a toxic gas produced by gas appliances and other sources. CO can cause health problems and even death in those exposed to the gas. Carbon monoxide displaces oxygen from hemoglobin, resulting in decreased oxygen being carried in the bloodstream and to the body's tissues. CO also directly inhibits cellular respiration by binding to cytochrome c oxidase.
Principles of Toxicology
1) Some theorists argue that there may be no clear threshold for effects such as carcinogenesis & mutation. What arguments do you think they might put forward in support of this?
2) It is important to understand the physiological means by which toxic agents cross cellular membranes & enter the cells of human body. Define & describe both passive & active transport?
3) Definition of toxicology?
4) What do you understand by the term dose? How can you estimate it?
5) What do you understand by the term effect? How is it measured?
6) Using examples distinguish between local and systemic and acute and chronic effects?
7) What do you understand by the term dose - effect and dose - response relations?
8) What is the impact on this relationship if there is more than one effect of a chemical?
9) What do you understand by the term 'threshold of effect'?
10) Define the terms toxico - kinetics and toxico - dynamics?
11) What factors influence chemical:
- Distribution and deposition
- Accumulation and elimination?
12) What do you understand by the term biological half time?
13) What is the significance, when setting threshold for adverse effects, of the fact that, broadly speaking, solid particulates have much longer biological half times than gases and vapours?
14) Briefly, what is the major underlying difference in body handling of a chemical between one and two compartment models of distribution and elimination?
15) Outline some general mechanisms of toxicity?
16) Describe a range of short and long-term toxicity testing methods?
17) Discuss the limitations of animal testing methods in the evaluation of human toxic potential of chemicals?
18) Outline a strategy for testing for carcinogenicity of industrial chemicalsView Full Posting Details
