Match each clinical scenario regarding consent or refusal of treatment with the most appropriate legal or ethical principle that guides the physician's action.
- A 16-year-old girl requests screening and treatment for a suspected sexually transmitted infection, explicitly asking that her parents not be informed.Treatment is authorized under a specific statutory exception for minors without parental notification.
- A 32-year-old capacitated pregnant woman at 38 weeks gestation actively refuses a life-saving cesarean delivery for complete placenta previa.The patient's autonomous decision supersedes potential harm to the fetus; treatment cannot be forced.
- An 82-year-old man with advanced dementia and no known family presents with a ruptured appendix requiring immediate surgery.Proceed with intervention based on the principle of emergency implied consent.
- The wife of a 60-year-old intubated ICU patient demands full resuscitation, despite his legally binding and documented 'Do Not Resuscitate' order.Documented prior competent directives override conflicting surrogate demands.
Cevap
16-year-old girl matches with statutory exception; Pregnant woman matches with patient autonomy overriding fetal harm; Man with dementia matches with implied consent; Wife demanding CPR matches with prior competent directives overriding surrogate.
Each scenario represents a distinct boundary case in medical ethics. Minors can consent to specific treatments (STIs, contraception, substance abuse) statutorily. Capacitated adults, including pregnant women, maintain the right to refuse any treatment. True emergencies involving incapacitated patients without surrogates rely on implied consent. Finally, clear advance directives always supersede the emotional demands of a surrogate.
