Post-Lab Questions

 

What were your controls for this experiment? What did they demonstrate? Why was saliva included in this experiment?

 

 

 

What is the function of amylase? What does amylase do to starch?

 

 

 Which of the foods that you tested contained amylase? Which did not? What experimental evidence supports your claim?

 

 

  Saliva does not contain amylase until babies are two months old. How could this affect an infant’s digestive requirements?

 

 

 

There is another digestive enzyme (other than salivary amylase) that is secreted by the salivary glands. Research to determine what this enzyme is called. What substrate does it act on? Where in the body does it become activated, and why?

 

 

 

Digestive enzymes in the gut include proteases, which digest proteins. Why don’t these enzymes digest the stomach and small intestine, which are partially composed of protein?

Post-Lab Questions

 What reaction is being catalyzed in this experiment?

  What is the enzyme in this experiment? What is the substrate?

  What is the independent variable in this experiment? What is the dependent variable?

  How does the temperature affect enzyme function? Use evidence from your data to support your answer.

  Draw a graph of balloon diameter vs. temperature. What is the correlation?

  Is there a negative control in this experiment? If yes, identify the control. If no, suggest how you could revise the experiment to include a negative control.

  In general, how would an increase in substrate alter enzyme activity? Draw a graph to illustrate this relationship.

 

Design an experiment to determine the optimal temperature for enzyme function, complete with controls. Where would you find the enzymes for this experiment? What substrate would you use?

Week 1 – Discussion

 

Your initial discussion thread is due on Day 3 (Thursday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses.
 

     

Interoperability   and Vocabulary Mapping.

Vocabulary mapping supports the interoperability of health information systems by using controlled vocabularies to increase communication between these systems. Think of a scenario in which two health information systems would need to transmit data to each other. In your response: Identify the two health information systems Give specific examples of ten terms these systems would      need to transmit to each other. For each term identify the category (one to one, narrow      to broad, broad to narrow or unmappable) that would be used as part of the      vocabulary map.

Guided response: Your initial post should be a minimum of 200-250 words. Utilize a minimum of two scholarly sources, excluding      the textbook. Sources should be cited in APA format, as outlined in      the Ashford Writing Center. You must respond to at least two of your classmate’s      posts by Day 7. Your three required posts must be on three different      days of the week.  After reading the other initial postings, include two      recommendations for one to one mapping.

Carefully review the Grading Rubric for the criteria that will be used to evaluate your discussion.

shford 4: – Week 3 – Assignment

Conflict Resolution at the St. Clare Hospital

The St. Clare Hospital was founded in 1988. In the past few years, the revenues have dropped steadily to a point where CEO James Edwards is considering cost control to improve the organization’s bottom line. Mr. Edwards understands physicians play a critical role in controlling cost, but they do not have a great interest in cooperating with him to sustain the viability of the hospital. Mr. Edwards decides to hire Wendy Jones as the chief operating officer and empower her to cut costs for the hospital.  The first measure taken by  Ms. Jones is to outsource the interpretation of imaging readings and fire the radiologist Dr. Harris. By doing so, the hospital would save $160,000 per year. However, after two weeks, the hospital sees 18% inaccuracy rates in outsourced reading reports. The hospital might face legal liabilities from inaccurate readings. Mr. Edwards and Ms. Jones want to stay with the plan to control costs, but the physicians are furious. The medical director, Dr. Wiseman, gathers all staff physicians to a call for action. 

Write a four-to six-page double-spaced paper (excluding title and reference pages), addressing the following:

Describe types of conflict identified in this case.Explain conflict management styles evidenced in this case.Propose a conflict resolution strategy to be used.  Recommend strategies to reduce cost and legal liabilities.

Including an introduction and conclusion paragraph, your paper must be four to six double-spaced pages (excluding title and reference pages) and formatted according to APA style as outlined in the  Ashford Writing Center. Utilize a minimum of three scholarly and/or peer-reviewed sources, including the textbook, that were published within the last five years. Document all references in APA style as outlined in the Ashford Writing Center  APA Checklist.

Substance Abuse Assessments Across the Lifespan

Substance abuse assessments have very different purposes for different populations. For instance, an assessment for treatment of victims will look different from a court-mandated assessment relating to criminal behavior. For another example, an assessment for an adolescent would likely emphasize peer influence more so than it would for an adult. These demographic factors significantly influence the assessment as it relates to treatment planning or other recommendations.

Use the module readings and the Argosy University online library resources to research types of substance abuse assessments for different demographics.

Select three substance abuse assessments for use in this assignment. Your choices should represent three different age populations such as the elderly, adults, adolescents, or children.

Review the American Society of Addiction Medicine (ASAM) patient placement criteria for the treatment of substance-related disorders at the following:

Mee-Lee, D. (2005). Overview of the ASAM patient placement criteria, second edition revised (ASAM PPC-2R). Substance Abuse & Mental Health Services Administration (SAMHSA). Retrieved from
https://www1.maine.gov/dhhs/oms/provider/pnmi/documents/ASAM-presentation-Dr-Lee.pdf

Substance Abuse and Mental Health Services Administration, Center for Substance Abuse Treatment. (2001). KAP KEYS Based on TIP 13: The role and current status of patient placement criteria in the treatment of substance use disorders. Retrieved from
http://integratedrecovery.org/wp-content/uploads/2010/08/TIP13-KAP.Keys_.pdf

Complete the following:

Describe the ASAM patient placement criteria for the treatment of substance-related disorders.

Describe the three selected types of substance abuse assessments that you might use. Be sure that your choices represent three different age populations such as the elderly, adults, adolescents, or children.

Compare and contrast the information being collected in each of the three assessments and describe the areas of concern. Ask, for example, does it include client presentation and functioning, current use and history, high-risk behavior, first exposure, consequences of addiction, culture, life skills, work, vocation, education, health, recreation, or spirituality? Present the comparison of the three types of substance abuse assessments in a table.

Explain special considerations, including ethical issues, which would apply to the different populations selected.

Evaluate the importance of having assessment tools for clients in each developmental life stage.

Create an 8–10 slide PowerPoint presentation to present your findings to other substance abuse counselors. Include the table comparing the three types of substance abuse assessments. Apply APA standards to citation of sources in your slides. Use the speaker notes in the slide show to further discuss the topics on each slide. In addition, make sure you have a title slide and a slide with references (in APA format).

Unit 7: Qualitative Analysis and The Research Critique Process

Topic 1: Identifying Themes and Patterns

Qualitative data analysis can be quite complex and time-consuming. Whether the research design is descriptive or uses a specific qualitative methodology such as phenomenology; the researcher will need to consider all the data that is generated from data gathering. Most qualitative data are gathered from interviews and the results examined for themes and patterns.

1. Please describe and discuss how themes and patterns emerge from the analysis of data.

2. Use the thematic findings from a credible qualitative nursing research study to demonstrate your description. Be sure the study you use is different from the qualitative study for the major Assignment. Please attach the study for others to view.

3. Provide at least three citations with full references to credible nursing scholarly articles supporting your definitions and discussion.

Ever since 9/11 the federal government has stressed the need
to plan for a terrorist incident involving a weapon of mass destruction (WMD)
The key consequence regarding management planning issues for a WMD incident are
medical and public health

The four major components for a response to a WMD incident
are threat assessment; emergency consultation; specialized technical
assistance, and additional assets as needed from the federal and private
sector Response plans should address these components Health response
requires cooperation with all state and local health agencies including private
health care providers

1 Is the health component adequately addressed in the
planning for a WMD incident?

2Do you believe that States and local governments,
including local health care facilities, will receive sufficient funding to
adequately plan and prepare for such an incident?
