Explain the progressive pathophysiologic relationship between an MI and the development of left ventricular (LV) failure.
Two assignments in one prompt, and the second is the one that gets dropped. Build a causal chain from infarct to pump failure, then write a genuinely separate DVT section from the CDC resource the brief names.

NU621 Unit 1 asks for a chain, not a description
The word carrying the marks is progressive. The prompt is not asking what left ventricular failure is; it is asking you to walk the road from an occluded coronary artery to a failing pump, step by step, so that each step causes the next. That chain has a standard shape and you should write it in order: occlusion, ischaemia, myocyte necrosis, loss of contractile mass, fall in stroke volume and ejection fraction, neurohormonal compensation through the sympathetic nervous system and the renin-angiotensin-aldosterone axis, then the pathological remodelling those same compensations drive. Ventricular dilation, wall thinning and fibrosis are what turn a survivable infarct into chronic failure, and naming remodelling as the hinge is what separates a graduate answer from an undergraduate one. The factors affecting severity follow directly from the chain: infarct size and location, whether the anterior descending territory is involved, how quickly reperfusion happened, prior infarcts, and comorbid load.
Then read Mr. T.'s numbers, because the case supplies specific modifiers and a post that never returns to them has answered a textbook question rather than this one. His pressure of 159/94 means the ventricle is already remodelling under afterload before any infarct occurs; a total cholesterol of 250 and a weight of 275 pounds at 5'11 set the atherosclerotic substrate; and the family history in father, brother and paternal grandfather is a non-modifiable risk that changes his pre-test probability, not just his anxiety. Note also that he is currently asymptomatic and untreated, which makes this primary prevention. The second half of the prompt is a separate task with its own deliverable, and it is the half most often lost: go to the CDC resource the brief names, and document DVT manifestations and management as a distinct section rather than folding a sentence about clots into the cardiac discussion.
Likely learning objectives
- Sequence the pathophysiology from coronary occlusion to left ventricular failure.
- Identify ventricular remodelling as the mechanism converting infarct to chronic failure.
- Relate a specific patient's risk profile to the severity determinants named.
- Produce a separate, sourced account of DVT manifestations and management.

NU621-8 Unit 1 DQ 1 Discussion Question/Prompt Read the following case study and answer the posed questions: Mr. T., a 45-year-old black man employed as a midlevel corporate manager, came to the doctor’s office seeking a physical examination. He appeared somewhat overweight. He denied taking any medications or smoking, but admitted drinking alcohol. His father and older brother have hypertension (HTN) and his paternal grandfather experienced a myocardial infarction (MI) and a CVA at a young age. Mr. T. stated, “A year ago at a health fair my cholesterol was tested. I was told later by mail that my cholesterol was 250 and I had to recheck my blood pressure.” His Bp at the time of his examination was 159/94, HR 96, weight 275, height 5’11 in. Explain the progressive pathophysiologic relationship between an MI and the development of left ventricular (LV) failure. What factors affect the severity of LV failure? Next, visit http://www.cdc.gov/ncbddd/dvt/facts.html (Links to an external site.) and access resources about deep vein thrombosis. Document the manifestations and management of clients with deep vein thrombosis. Submit a summary of some of the things you learned from this video. Responses need to address all components of the question, demonstrate critical thinking and analysis, and include peer reviewed journal evidence to support the student’s position. Please be sure to validate your opinions and ideas with citations and references in APA format. Please review the rubric to ensure that your response meets the criteria. Estimated time to complete: 2 hours Discussion Peer/Participation Prompt Look at your course colleagues’ responses. NU621-8 Unit 1 DQ 1 From your advanced practice mindset reflect on a discussion you would like to have with two of your course colleagues about their responses. Post a response individually to each of them that expresses your advanced practice nursing role perspective of the data represented in their response. Use scholarly resources relevant to your advanced practice nursing role to support the key elements of the peer discussions you construct. [For example – if you are a nurse educator (clinical or academic) what are your thoughts about their ability to follow task instructions for constructing the assignment, etc.?; if you a nurse leader what are your thoughts about the success of their application of a process improvement model, etc.?; if you are a nurse practitioner what are your observations about the non-conventional modality presented in the schemata, can you locate any evidence or the foundational basic sciences that support the modality, etc.? Responses need to address all components of the question, demonstrate critical thinking and analysis, and include peer reviewed journal evidence to support the student’s position. Please be sure to validate your opinions and ideas with citations and references in APA format.
Course-wide instructions that accompany this question
ADDITIONAL INSTRUCTIONS FOR THE CLASS Discussion Questions (DQ) Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words. Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source. One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words. I encourage you to incorporate the readings from the week (as applicable) into your responses. Weekly Participation Your initial responses to the mandatory DQ do not count toward participation and are graded separately. In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies. Participation posts do not require a scholarly source/citation (unless you cite someone else’s work). Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week. APA Format and Writing Quality Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required). Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation. I highly recommend using the APA Publication Manual, 6th edition. Use of Direct Quotes I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly. As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content. It is best to paraphrase content and cite your source. LopesWrite Policy For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me. Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes. Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own? Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score. Late Policy The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies. Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances. If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect. I do not accept assignments that are two or more weeks late unless we have worked out an extension. As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading. Communication Communication is so very important. There are multiple ways to communicate with me: Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class. Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.

Before you post to the Unit 1 forum
Common mistakes
- Describing what heart failure is instead of tracing how it develops.
- Omitting neurohormonal compensation and the remodelling it drives.
- Never returning to Mr. T.'s blood pressure, cholesterol or family history.
- Reducing the DVT half to a sentence rather than a documented section.
- Treating the family history as a soft factor rather than a risk determinant.
Submission checklist
- Does your chain run occlusion to necrosis to remodelling in order?
- Have you named remodelling explicitly as the hinge?
- Are the severity factors tied back to this patient's numbers?
- Is the DVT content a section of its own with its own sources?
- Are all claims supported by peer-reviewed evidence in APA format?
