Match each clinical scenario involving informed consent, refusal of care, or capacity to the specific ethical or legal principle that best classifies the situation.
- A surrogate decision-maker refuses a medically indicated blood transfusion for an incapacitated patient, citing the patient's previously written advance directive that explicitly declines blood products.Valid exercise of substituted judgment
- A physician diagnosing a brain tumor in a patient with severe, unstable paranoia withholds the information temporarily because full disclosure is highly likely to precipitate an immediate suicide attempt.Therapeutic privilege
- A public health department detains a patient with active, smear-positive pulmonary tuberculosis who is refusing antimicrobial treatment and attempting to return to a crowded homeless shelter.Public health limitation of autonomy
- An intoxicated patient with slurred speech and an unsteady gait demands to leave the emergency department immediately before an evaluation for a head injury can be completed.Transient lack of decision-making capacity
Cevap
The scenarios represent substituted judgment (surrogate following directives), therapeutic privilege (withholding info to prevent suicide), public health exception (tuberculosis detainment), and transient incapacity (acute intoxication).
Each scenario highlights a core ethical boundary where the standard informed consent process is modified. Surrogates may refuse care if following documented wishes. Physicians may invoke therapeutic privilege to prevent severe imminent harm. Public health threats override individual autonomy. Finally, transient intoxication temporarily invalidates decision-making capacity, requiring the physician to act in the patient's best interest until capacity returns.
