Should we withhold life support? The Mr. Martinez case
A DNR order and a respiratory failure caused by a staff error — two facts that pull the obvious answer apart, and the brief removes the surrogate who might have resolved it.

Two facts that pull the obvious answer apart
The case is constructed so the obvious answer is wrong, and seeing why is most of the assessment. Mr Martinez has a valid DNR order, so the reflex reading is that nothing should be done. But a DNR order refuses cardiopulmonary resuscitation; it is not a refusal of all treatment, and it says nothing about transfer to intensive care, ventilation, or oxygen titration. Read the case again and the second decisive fact appears: his respiratory failure was *caused by his oxygen being inadvertently turned up*. This is not the natural progression of his disease. It is an iatrogenic harm, and treating a harm the institution caused is a different question from prolonging a dying process the patient declined. State both facts in the opening paragraph, because everything the assessment asks for afterwards is easier to argue once the reader knows the question is not simply whether to honour a DNR.
Those two observations should structure the paper, because the brief's first required element is *the patient's directives*. Say precisely what the directive covers and what it does not. A DNR is a scope-limited refusal made in anticipation of a particular event; extending it into a general instruction to withhold care is a substitution of the clinician's judgement for the patient's, which is the failure of respect for autonomy dressed up as compliance with it. The stronger reading is that Mr and Mrs Martinez refused resuscitation from an expected cardiopulmonary arrest, and that a reversible complication of a treatment error was not the circumstance either of them had in mind. Say what the paper would conclude on the opposite reading too, since showing that you considered the broad interpretation and rejected it for a reason is stronger than never having noticed it.
*The patient's quality of life* is the element that most often goes wrong, because students answer it about the patient rather than about the judgement. Quality of life is the patient's own assessment, not the clinician's estimate of what a life with advanced COPD is worth, and the evidence here is that he was being treated actively and *seemed to be doing better* — a man expected to recover from this admission. Where his own view is unavailable, the paper should say so and explain what standard applies instead: substituted judgement where prior wishes are known, and best interests only where they are not. Getting that hierarchy the right way round is a demonstrable competency. Say explicitly which standard you are applying and on what evidence, because the assessment's competency wording is about demonstrating sound ethical thinking rather than about reaching a particular result.
The brief adds a constraint that changes everything and is easy to miss: *assume that doctors cannot contact Mrs Martinez and must make this choice on their own*. That removes the surrogate, so the paper cannot resolve the case by deferring to family. What survives is the prior directive as evidence of values, the clinical facts, and the ethical principles. It also raises the emergency question — whether treatment may proceed under presumed consent while the surrogate is unreachable — which is a real doctrine and worth naming. Note the brief still asks for *the family's stated preferences*: those exist, in the joint DNR request, and should be reported as evidence even though the family cannot be consulted now. Note also that the constraint is artificial and says so, which means the paper can acknowledge that contacting her would ordinarily be the first step while still answering the question as posed.
The last required element names the trap explicitly: *any conflicts of interest that might arise because of the patient's respiratory failure*. The failure was caused by a staff error. An institution facing potential liability has an interest in how the event is characterised and in what happens next, and a decision to withhold escalation could be — or could later appear to be — influenced by that interest rather than by the patient's. Name it directly, say why it must not enter the clinical decision, and say what disclosure is owed. Then apply the four principles by name to reach a conclusion in two to three pages, with autonomy, non-maleficence, beneficence and justice each doing identifiable work. Two to three pages is short for six required elements, so allocate roughly a paragraph each and resist retelling the case, which the marker has already read.
Required element | The reading that fails | The reading the case supports |
|---|---|---|
Patient's directives | DNR means withhold everything | A DNR refuses CPR; it is scope-limited |
Cause of the deterioration | COPD progression | Iatrogenic: the oxygen was turned up in error |
Quality of life | The clinician's estimate of a COPD life | The patient's own view; he was improving |
Family's preferences | Unavailable, so ignored | The joint DNR request is stated evidence |
The surrogate | Defer to Mrs Martinez | The brief removes her; decide without |
Moral issues | Killing versus letting die, in the abstract | Whether this death is caused or permitted |
Conflicts of interest | Not addressed | Institutional liability for the error |
Ethical principles | Named in a list | Each applied to a specific fact of the case |

- 02Distinguish disease progression from iatrogenic harm in an ethical analysis.
- 03Apply substituted judgement and best interests in the correct order.
- 04Identify an institutional conflict of interest and say what follows from it.

From the directive's scope to a justified decision
The directives, read for scope
State what the DNR refuses and what it leaves open.
What caused the crisis
Identify the respiratory failure as iatrogenic rather than disease progression.
Quality of life and the standard of decision
Apply the patient's own view, then substituted judgement, then best interests.
Deciding without the surrogate
Work the case under the brief's own constraint.
Conflicts of interest
Name the institutional interest created by the error, and its consequences.
Principles and decision
Apply the four principles to the facts and reach a justified conclusion.
Reading DNR scope before reading euthanasia ethics
Recommended databases
- Journal of Medical Ethics and American Journal of Bioethics
- NCBI Bookshelf
- PubMed Central
- The assessment's suggested resources
Search sequence
- 1.Read a reference on the scope and limits of DNR orders first, because the whole analysis turns on what the directive does and does not cover.
- 2.Search the ethics literature on withholding versus withdrawing treatment, which is the moral-issues element and has a substantial and genuinely contested literature.
- 3.Look up decision-making standards when a surrogate is unavailable, since the brief's constraint removes the ordinary route and the emergency doctrine has to be named accurately.
- 4.Find guidance on disclosure after harm, which is what turns the conflict-of-interest element from an observation into an obligation.
Directives, refusal of care and withdrawal ethics
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.

Withholding and withdrawing life support in critical care settings: ethical issues concerning consent
Journal of Medical Ethics · 2007
Directly on the brief's central element, and specifically on consent — which is what the case removes when it takes Mrs Martinez out of reach. Use it to argue what may be done, and on what authority, when the surrogate cannot be consulted.
- 02
Advance Directives
StatPearls, NCBI Bookshelf · 2023
The reference that establishes what a DNR order actually is and what it covers, which is the foundation of the paper's first and most consequential move. It also sets out the decision-making hierarchy the quality-of-life element depends on.
- 03
Refusal of Care
StatPearls, NCBI Bookshelf · 2023
Clarifies the conditions under which a refusal is valid and how far it extends, which is what lets you argue that a refusal made in anticipation of one event does not govern a different one. Central to the scope argument.
- 04
Withdrawal Aversion and the Equivalence Test
The American Journal of Bioethics · 2019
The best available source for the moral-issues element, because it examines the intuition that withholding and withdrawing differ morally and tests it. Citing it lets you engage the killing-versus-letting-die question with an argument rather than with a definition.
- 05
Limitation of life sustaining therapy in disorders of consciousness: ethics and practice
Brain · 2024
Current work on how limitation decisions are actually justified in practice, including the role of prognostic uncertainty. Useful for the implications section, where the paper has to say what follows from deciding under incomplete information.
