An attending physician is evaluating four different patients to determine their medical decision-making capacity and the appropriate next ethical or legal steps. Match each clinical scenario with the most accurate capacity determination and clinical action.
- A 78-year-old man with urosepsis who is oriented only to person, exhibits a fluctuating level of consciousness, and refuses IV antibiotics, stating, 'The wires are biting me.'Lacks capacity due to an acute, reversible encephalopathy; urgent treatment decisions should be guided by a surrogate or implied consent.
- A 34-year-old woman with severe anemia from a ruptured ectopic pregnancy who is fully alert, understands the fatal risks of refusing blood products, but declines them citing deeply held religious beliefs.Demonstrates intact decision-making capacity; the physician must respect the informed refusal despite the potentially fatal consequences.
- An 85-year-old woman with advanced Alzheimer disease who cannot recognize family members and requires a feeding tube evaluation; her son presents a valid durable power of attorney for healthcare.Lacks capacity due to a chronic, progressive neurocognitive disorder; medical decisions must be deferred to the legally appointed healthcare agent.
- A 45-year-old man with chronic schizophrenia who experiences auditory hallucinations but clearly articulates the risks, benefits, and alternatives of a recommended inguinal hernia repair, demonstrating logical reasoning.Demonstrates intact decision-making capacity for the proposed intervention; informed consent should be obtained directly from the patient.
Answer
Match delirium with surrogate/implied consent, religious refusal with honoring the patient's choice, advanced dementia with the legal proxy, and controlled schizophrenia with direct patient consent.
Decision-making capacity is a clinical determination assessing a patient's ability to understand their condition, appreciate the consequences of their choices, reason through alternatives, and clearly communicate a preference. It is specific to the decision at hand. Acute delirium and advanced dementia impair these abilities, necessitating a surrogate. However, psychiatric diagnoses (like schizophrenia) do not automatically void capacity if the patient demonstrates rational understanding of the specific intervention. Furthermore, capacitated adults have the fundamental right to refuse any treatment, even if the result is death, as seen in religious objections.
Step-by-Step Solution
Key Concept
Decision-Making Capacity requires understanding, appreciation, reasoning, and expressing a choice. It is decision-specific and not automatically negated by psychiatric illness.
