Clinical meaning
The four foundational bioethical principles (Beauchamp and Childress) -- autonomy, beneficence, nonmaleficence, and justice -- form the ethical framework for all NP clinical decision-making. AUTONOMY is the patient's right to self-determination: the right to make informed decisions about their own healthcare, including the right to refuse treatment, even when the clinician disagrees. Autonomy requires that the patient has decision-making capacity (not the same as legal competency), which is assessed by determining whether the patient can: (1) understand the relevant information, (2) appreciate how it applies to their situation, (3) reason about the options, and (4) communicate a consistent choice. Capacity is decision-specific and time-specific -- a patient may have capacity for one decision but not another, or may regain capacity after delirium resolves. BENEFICENCE is the obligation to act in the patient's best interest and promote their welfare. The tension between autonomy and beneficence creates the most common ethical dilemmas in NP practice: paternalism occurs when the clinician overrides patient autonomy 'for their own good' (e.g., pressuring a competent patient to accept a treatment they have refused). The NP must respect autonomy even when the patient's choice conflicts with what the NP believes is best. INFORMED CONSENT operationalizes both principles: the NP must disclose the diagnosis, proposed treatment (including nature, risks, benefits, and alternatives), and expected outcomes in language the patient can understand; verify understanding through teach-back; and obtain voluntary consent without coercion. Informed consent is NOT merely obtaining a signature -- it is a process of shared decision-making. The NP must also recognize exceptions to standard informed consent: emergency situations (implied consent), therapeutic privilege (rare, narrowly applied), patient waiver of informed consent, and situations involving substitute decision-makers for patients without capacity.
