A client who is unconscious and has extensive internal injuries arrives via ambulance to the emergency department. The staff cannot reach the client's family. Which of the following permits the staff to proceed with emergency surgery?

Choice A reason: Decreased cost-effectiveness is not an outcome of critical pathway use, but rather an outcome of poor quality care. Critical pathways are designed to improve the quality and efficiency of care by reducing unnecessary costs and resources.

Choice B reason: Decreased care delays is an outcome of critical pathway use, as it reflects the timely and coordinated delivery of care. Critical pathways are evidence-based plans that outline the expected course of care and outcomes for a specific client population.

Choice C reason: Increased length of stay is not an outcome of critical pathway use, but rather an outcome of ineffective or inappropriate care. Critical pathways are intended to shorten the length of stay by optimizing the care process and preventing complications.

Choice D reason: Increased variation in clinical interventions is not an outcome of critical pathway use, but rather an outcome of inconsistent or individualized care. Critical pathways are meant to standardize the clinical interventions based on the best available evidence and practice guidelines.

Choice A reason: This is the correct choice because autonomy is the ethical principle that respects the client's right to make their own decisions about their health care. The nurse should honor the client's wishes and preferences, even if they differ from the nurse's or the provider's. The nurse should not force or coerce the client to accept blood transfusions, as this would violate their autonomy.

Choice B reason: This is not the correct choice because fidelity is the ethical principle that requires the nurse to be faithful and loyal to the client and their agreement. The nurse should keep their promises and commitments, and act in the best interest of the client. The nurse should not administer blood transfusions to the client without their consent, as this would breach their trust and fidelity.

Choice C reason: This is not the correct choice because justice is the ethical principle that ensures fair and equal treatment for all clients. The nurse should distribute resources and services according to the client's needs and rights, and avoid any discrimination or bias. The nurse should not administer blood transfusions to the client against their will, as this would disregard their justice.

Choice D reason: This is not the correct choice because veracity is the ethical principle that obliges the nurse to be honest and truthful with the client. The nurse should provide accurate and complete information, and disclose any errors or risks. The nurse should not administer blood transfusions to the client without informing them, as this would violate their veracity.
