Comprehensive Case Study: COPD, Heart Failure, Diabetes
Four conditions in one patient, answered as a single narrative rather than a numbered list. The interactions between the diseases are what the narrative form is designed to expose.

One narrative, four diseases, and they interact
The format rule is doing real work here, so read it before the questions. You must write one narrative with an introduction and a conclusion rather than a numbered set of answers, and that constraint exists because M.K.'s conditions are not four separate problems. Her chronic bronchitis, her right-sided heart failure, her hypertension and her type II diabetes are causally linked, and a numbered answer sheet lets you describe each in isolation without ever making the connection. Chronic hypoxaemia from bronchitis produces pulmonary vasoconstriction; sustained pulmonary hypertension loads the right ventricle; the right ventricle fails, which is what her distended neck veins and peripheral oedema are telling you. That chain is cor pulmonale, it explains three of her findings at once, and it is the single most valuable paragraph you can write. Write that chain out before you answer any individual question, because every later answer refers back to it.
Answer every question, but let the narrative carry them. Name her clinical findings and say which mechanism produces each — the morning cough with sputum, the light-headedness, the distended neck veins, the oedema. Use the actual hypertension staging thresholds rather than describing her pressure as high, and connect her medications to the mechanism they act on rather than listing their classes. For the lipid panel, say what the specific values put her at risk of and why diabetes multiplies that risk. Interpret the HbA1c against the diagnostic and target thresholds and explain what glycated haemoglobin actually measures, since that is the part most answers skip. Three sources minimum, one of them not from the internet, and the textbook does not count — so plan a library trip or a print reference before you start writing, because that requirement catches people at the very end. Name the non-internet source in your reference list so a marker can see the requirement was met.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Trace the pathophysiological chain linking chronic lung disease to right heart failure.
- 02Match clinical findings to their underlying mechanisms.
- 03Apply current staging thresholds for hypertension and glycaemic control.
- 04Integrate multiple comorbidities into a single coherent explanation.
Read the full question
Review every instruction before using the planning guidance that follows.
Turn the brief into deliverables
- 01One continuous narrative with an introduction and conclusion.
- 02Clinical findings correlated with chronic bronchitis.
- 03The type of heart failure, with its pathogenesis explained.
- 04Hypertension stage with rationale for her medications.
- 05Lipid panel interpretation and additional medication recommendations.
- 06HbA1c interpretation against normal and target values.
- 07At least three sources, one non-internet, excluding the textbook.
Answer every question, but write it as one piece
Introduction: one patient, four diagnoses
Frame the case as an interacting system rather than a list.
Chronic bronchitis and its findings
Correlate cough, sputum and gas exchange with the pathology.
From lung to right heart
Explain cor pulmonale and identify the type of heart failure.
Hypertension: stage and treatment rationale
Stage her pressure and justify her regimen mechanistically.
Lipids, diabetes and combined risk
Interpret the panel and recommend additional therapy with reasons.
HbA1c and conclusion
Interpret the value and close by tying the four conditions together.
Guidelines for each condition, and one non-internet source
Recommended databases
- GOLD reports
- MedlinePlus and NHLBI
- NCBI Bookshelf
- A print reference from your library
Search sequence
- 1.Get current staging thresholds from a guideline rather than from memory.
- 2.Read the cor pulmonale pathway once so the chain is accurate.
- 3.Find your non-internet source early; leaving it to the end is the usual failure.
- 4.Check that each medication's mechanism is stated, not just its class.
Reference shortlist
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.

Review before submission
Common mistakes
- Numbering the answers, which the assignment explicitly forbids.
- Treating the four conditions as unrelated problems.
- Describing blood pressure as high instead of staging it.
- Using only internet sources when a non-internet source is required.
Submission checklist
- Is the response one narrative with an introduction and conclusion?
- Have you named the type of heart failure and explained how it developed?
- Are the hypertension stage and the HbA1c interpreted against thresholds?
- Do you have three sources with at least one that is not from the internet?
