Define ethical issues related to sedation at the end of life and the principle of double effect.

• A. Sedation is never ethically permissible.
• B. Sedation should always be used with intent to shorten life.
• C. Sedation to relieve suffering may be ethically permissible when the intent is to relieve suffering, with proportionality, and the life-shortening effect is secondary; consider alternatives.
• D. Always consult family to override patient wishes.

Answer: (C)

The main concept being tested is how end-of-life sedation can be ethically justified using the principle of double effect. This framework lets a clinician perform an action that has a beneficial intended outcome—relief of suffering—while acknowledging a potential, foreseen adverse outcome—possible shortening of life—only if certain conditions are met. The intention must be to relieve suffering, not to shorten life. The life-shortening effect is a secondary consequence, not the aim. The level of sedation and the overall plan must be proportionate to the patient’s symptoms, meaning the benefit of symptom relief justifies any burdens from the treatment. Alternatives should be explored and used if they can adequately relieve suffering; sedation is considered when it reasonably serves the patient’s comfort and dignity.

Respect for patient autonomy is central: obtain informed consent when possible, and involve surrogates if the patient cannot decide, without overriding the patient’s known wishes unless ethically justified. It’s also important to distinguish this approach from euthanasia or physician-assisted dying, since the critical factor is the clinician’s intended purpose.

Why the other notions don’t fit: saying sedation is never ethically permissible ignores real-world palliative care where relief of suffering can be ethically appropriate. insisting the intent is to shorten life reverses the required primary aim of relief of suffering. and while family input is valuable in care decisions, it does not override a competent patient’s wishes.
