Difficulty: MediumInformed Consent and Refusal

Match each clinical scenario with the most appropriate ethical standard or legal doctrine guiding the medical decision-making process.

  • A 62-year-old incapacitated man's wife declines hemodialysis on his behalf, stating, "He always told me he never wanted to be tied to a machine if his kidneys failed."Substituted judgment standard
  • An unidentified 40-year-old woman is brought to the trauma bay unresponsive with a tension pneumothorax, and the physician immediately performs a needle thoracostomy.Implied consent (emergency exception)
  • A physician temporarily delays informing a severe, acutely suicidal psychiatric inpatient about a new diagnosis of Huntington disease to prevent an imminent self-harm attempt.Therapeutic privilege
  • A legally appointed guardian of a 30-year-old with severe congenital encephalopathy consents to a dental extraction, determining it will alleviate the patient's pain.Best interest standard

Answer

The wife's decision matches the substituted judgment standard. The trauma intervention matches implied consent. Withholding the Huntington diagnosis matches therapeutic privilege. The guardian's consent matches the best interest standard.
Each scenario illustrates a distinct, well-defined exception to the standard informed consent process or a specific standard for surrogate decision-making. Substituted judgment applies when prior wishes are known; best interest applies when they are not or the patient never had capacity. Implied consent is for emergencies, and therapeutic privilege is for preventing immediate, severe psychological harm.

Step-by-Step Solution

1
Analyze the first scenario regarding the incapacitated man.
The surrogate is using the patient's known past statements to make a choice.
When a surrogate relies on what the patient would have chosen based on prior expressed wishes, this specifically defines the substituted judgment standard.
2
Analyze the second scenario regarding the trauma patient.
A life-saving procedure is performed on an unresponsive patient without a surrogate available.
In true emergencies where taking time to obtain consent would result in serious harm or death, the law assumes implied consent.
3
Analyze the third scenario regarding the suicidal patient.
A diagnosis is intentionally withheld due to an immediate threat of suicide.
Therapeutic privilege allows physicians to withhold information if disclosure would cause severe, immediate psychological harm, though it cannot be used merely to avoid upsetting a patient.
4
Analyze the fourth scenario regarding the patient with severe congenital encephalopathy.
The guardian makes a decision to alleviate pain for someone who never had decision-making capacity.
When a patient has never been capacitated (e.g., profound lifelong cognitive disability, infant), surrogates must apply the best interest standard, maximizing benefit and minimizing harm.
