How to Answer the NBHS1314 Digoxin and Warfarin Case Essay
Short answer: the strongest NBHS1314 digoxin, furosemide and warfarin essays treat the case as one connected story, not five separate drug write-ups. Low potassium from furosemide makes digoxin toxic, ibuprofen and ginkgo biloba stack extra bleeding risk onto warfarin, and the marks sit in showing those links, ranking the immediate risks with a reason, and keeping nursing actions within the nurse’s role.
If you would like to see a worked extract before you plan your own, there is a reference-only model answer for this brief. It is for study and comparison, not for submission. Questions that arrive later will appear in our recently solved questions list.
What this Part I task is really testing
The brief describes a 68-year-old man with chronic heart failure and atrial fibrillation who is admitted with nausea, poor appetite, weakness, blurred yellow vision, gum bleeding and bruising. His pulse is slow and irregular, his potassium is low, his digoxin level is high and his INR is raised. He has also been taking an over-the-counter anti-inflammatory and a herbal supplement without telling anyone.
Read it as a medication-safety case. The prescribed drugs are not wrong in themselves. The failure lies in monitoring, in disclosure and in what happens when several drugs act on the same organ systems. Markers want to see that you can reason across drugs, not recite a monograph for each.
The full assessment is 40% and Part I is the 30% essay, written to 2,500–3,000 words excluding references. Check your own course guide for the exact deadline and rubric, because details can change between semesters.
Where the marks sit
| Rubric area | Approximate weight | What earns the marks |
|---|---|---|
| Introduction and case context | Small (about 2 of 40 on the scale in the brief) | A short, accurate summary of the case and a clear statement of what the essay will argue |
| Critical analysis of actions, adverse effects and interactions | Largest single block (about 10 of 40) | The furosemide, hypokalaemia and digoxin chain, plus the combined bleeding risk |
| Comparison and prioritisation of immediate risks | About 6 of 40 | A ranked comparison with reasons, and the conditions that would change the ranking |
| Nursing management, monitoring, education and medication safety | The remaining marks | Specific, justified actions in a sensible order, with prevention as well as rescue |
| Conclusion, references and organisation | The remaining marks | Current sources, consistent APA, and clean structure |
The weightings above follow the rubric in the brief as we read it. Treat them as a guide and confirm them against your own assessment document.
A step-by-step plan for the essay
- Open with the case in four or five sentences. State the key findings and your thesis. Most students waste the first 400 words retelling the brief. Do not.
- Explain each drug briefly: action, then adverse effect, then link to this patient. Keep each drug to a tight paragraph, and always end it with how it connects to the presentation.
- Build the digoxin chain explicitly. Furosemide causes potassium loss, low potassium makes digoxin more toxic, and reduced kidney function raises digoxin levels further. Say that the toxicity can appear even at moderately raised levels when potassium is low.
- Build the bleeding chain separately. Warfarin with a high INR, an NSAID that affects platelets and the stomach lining, and a herbal product with possible antiplatelet activity.
- Rank the two risks, with reasons. Name the one you place first, justify it and say what finding would reverse your decision.
- Move to nursing practice. Immediate actions, monitoring, escalation, education and prevention, each tied to a reason.
- Conclude in one short paragraph that restates the argument and the main preventable failures.

How to rank digoxin toxicity against bleeding
This is the part of the task where answers diverge. A weak answer lists both problems and says both are serious. A good answer commits to an order.
The usual argument places digoxin toxicity first. With a slow irregular pulse, low potassium and a raised level, the heart can move into a dangerous rhythm without much warning. The bleeding described so far is gum bleeding and bruising, which is clinically important but is not, on the information given, a major haemorrhage.
Then qualify it. If the patient showed black stools, vomited blood, had a falling blood pressure or developed new neurological symptoms, bleeding would move to the top. Writing that sentence shows you understand prioritisation as a living judgement, not a fixed list. It is a short sentence that often separates a good grade from an excellent one.
A quick comparison table you can adapt
| Question to answer | Digoxin toxicity | Bleeding on warfarin |
|---|---|---|
| Why is it a risk now? | Slow irregular rhythm, low potassium, high level | Raised INR with visible bleeding |
| Worst outcome? | Serious rhythm disturbance or cardiac arrest | Major internal or intracranial bleeding |
| How fast could it worsen? | Potentially quickly | Often more gradual unless a major bleed occurs |
| What must the nurse watch? | Heart rate, rhythm, symptoms, potassium | Bleeding sites, stools, observations, neurological status |
Nursing actions: keep them in scope
Do not write treatment doses. Markers in a nursing module are looking for nursing judgement, and a dose recited from memory adds risk without adding marks. Write that treatments are given “as prescribed and in line with local protocol”.
Strong actions to justify include a rapid assessment of airway, breathing and circulation, continuous heart monitoring, urgent medical escalation, and withholding the suspect medicines until a prescriber reviews them. Add a structured bleeding check, repeat blood tests (electrolytes, kidney function, full blood count and INR), fluid balance and falls precautions.
For education, explain why the patient must tell clinicians and pharmacists about every over-the-counter and herbal product, how to recognise warning symptoms, and why regular blood tests matter. Use teach-back, and mention a safer pain plan agreed with a prescriber or pharmacist. In Malaysia, many people use traditional and complementary products alongside prescribed medicines, so a respectful, non-judgemental conversation is more effective than a lecture.
Mark-maximising checklist
- The furosemide, low potassium and digoxin link is stated in plain words, not implied.
- The combined bleeding risk names all three contributors: warfarin, ibuprofen and ginkgo biloba.
- Your priority decision includes its justification and the finding that would change it.
- No treatment doses are given; wording like “as prescribed per protocol” is used.
- Education covers disclosure, symptoms, blood monitoring and safer pain relief.
- Sources are recent, from journals, clinical guidelines or professional bodies, and your referencing is consistent in APA.
- The word count excludes the reference list and stays within 2,500–3,000.
Common mistakes
- Five mini-essays. One section per drug with no links between them loses the critical analysis marks.
- Forgetting ginkgo and ibuprofen. They are in the case on purpose.
- Ignoring the kidneys. Digoxin is cleared mainly by the kidneys, and ibuprofen can reduce renal function.
- Quoting a single fixed digoxin range as universal. Ranges vary by laboratory and indication, so say that.
- Doses and drug names copied from textbooks. Keep the discussion at the level of nursing responsibility.
- A thin conclusion. Spend four or five sentences on it.

Frequently asked questions
Can I answer the essay in Malay?
The brief allows English or Malay. Pick the language in which you can write precise clinical reasoning, and keep it consistent throughout the essay.
Do I need to discuss Part II in this essay?
No. Part II is the online forum activity and is assessed separately. Your Part I essay should stay focused on the case.
Should I say which risk is worse, digoxin toxicity or bleeding?
Yes. The task asks you to compare and prioritise, so commit to an order with a reason. Add the clinical change that would reverse the order.
How much drug-action detail is enough?
Enough to explain the link to this patient. One or two sentences on mechanism per drug is usually sufficient, followed by the adverse effect and the interaction that matters here.
Can I include doses of antidotes or potassium replacement?
It is safer not to. Describe the nurse’s role in preparing for and monitoring treatment, and state that doses are prescribed and follow local protocol.
What counts as recent evidence?
Current clinical guidelines, peer-reviewed journals and professional bodies from the last several years are the best choices. Check your course guide for its own age limit on sources.
