Module 1 Discussion

Food Gone Bad!

Directions:

Pasteurization, a process named in honor of French chemist, Louis Pasteur, uses heat to destroy pathogenic microorganisms in foods and beverages such as milk, cheese, fruit juices, and canned goods. Its intended use is to increase the shelf-life and stability of many foods. 

For your initial post, define the pasteurization process. Do you think pasteurization necessary? What about countries that don’t use pasteurization? How are they able to safely consume products like unpasteurized dairy products? Do you think raw milk and dairy products should be more or less available? 

For your reply post, expand on your peers’ ideas by sharing examples of what you learned about pasteurization and suggest outside resources that support your perspective. 

Please make your initial post by Tuesday, and respond to at least one other student's post by the end of the day Saturday. Please check the Course Calendar for specific due dates.

Module 2 Discussion

How Clean Is Too Clean?

Directions:

The use of antibacterial products in hospitals and medical facilities is a necessary and common practice in order to prevent the transmission of disease-causing microorganisms. We have seen an increase in the use of these products, such as antibacterial hand soaps, hand sanitizers, antimicrobial wipes and cleaning sprays, and even dishwashing liquids in healthy households.  

For your initial post, provide examples of household products that contain antimicrobial compounds and share the potential benefits as well as any potential harm they could cause with overuse. Do you think daily and frequent use of these types of products within a healthy home is a good idea? Should the FDA have banned the marketing of antibacterial ingredients such as triclosan and triclocarban in the majority of household products? After your research, do you think you will increase or decrease your use of these types of products in your home? 

For your reply post, respond to at least one of your peers about the benefits and potential harms of using these types of products in a healthy household.

Please make your initial post by midweek, and respond to at least one other student's post by the end of the week.

What Goes Around Comes Around

Directions:

Have you heard of the so-called "5-second rule" for when food falls to the floor? (NOT true, by the way) Have you seen the signs in restrooms indicating that all employees must wash their hands before returning to work? Bacteria are everywhere, and the concept of cleanliness should apply to anyone who comes in contact with foreign materials, fecal matter or urine, or any potentially contaminated materials.

For your initial post, discuss which two rooms in your home or workplace that you believe are the most contaminated. Explain why you chose these two rooms and list at least two bacteria that are the common types found in those rooms.

Viral Treatment Options

Directions:

There are many opinions on the need and/or importance of vaccines in preventing the spread of disease. Our children are required to get vaccinations before entering school, and healthcare workers must have them when working in environments where they can come into contact with bloodborne pathogens. In healthcare facilities, human immunodeficiency virus (HIV) and Hepatitis C (HCV) are the two most prominent infectious concerns for medical staff.

For your initial post, research the two diseases HIV and HCV. Based on your research, discuss whether you think that a vaccine will be developed for either of these diseases within the next ten years. Why or why not?

For your reply post, expand on your peers' ideas by sharing examples from your own experience or readings, suggesting outside resources to support the topic, and/or asking furthering questions to dig deeper into the topic.

What’s Eating You?

Directions:

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the more prevalent nosocomial infections in healthcare faculties today. Any patient with a compromised immune system or open wound is susceptible to contracting MRSA from medical staff or even family members. Although MRSA is commonly connected to health care facilities, MRSA can be found anywhere.

For your initial post, discuss who you believe to be at the highest risk for MRSA outside the health care environment? Explain. Discuss the common fomites—or transmission factors—involved, as well as the preventative measures the public can do to reduce or prevent MRSA infections.

For your reply post, expand on your peers' ideas by sharing examples from your own experience or readings, suggesting outside resources to support the topic, and/or asking furthering questions to dig deeper into the topic.

Module 6 Discussion

Microbial Transmission Routes in Hospitals

Directions:

Hospitals and other healthcare settings will often implement Transmission-Based Precautions to prevent or help reduce the spread of infections to healthcare workers, as well other patients in their care. These Transmission-Based Precautions are designed to supplement standard precautions in patients/residents with documented or suspected infection/colonization of highly transmissible or epidemiologically important pathogens. The three categories of Transmission-Based Precautions include:

Contact Precautions

Droplet Precautions

Airborne Precautions

For your initial post, choose one of the Transmission Based Precautions listed above to report on. Research your selection and provide answers to the following questions: When should the precaution be implemented? What type of PPE should be used by a health care worker providing care to the patient? Are there any other considerations that apply when caring for a patient with this type of precaution? Finally, list some examples of diseases that fall into this category. 

For your reply post, expand on your peers' ideas by sharing examples from your own experience or readings, suggesting outside resources to support the topic, and/or asking furthering questions to dig deeper into the topic.
