Final answer:
In critical situations, nurses should make decisions based on ethical considerations, clinical knowledge, principled prioritization such as life before limb, and the hierarchy of human needs while handling ethical dilemmas with respect to dignity and safety.
Step-by-step explanation:
In critical situations guiding a nurse's decisions regarding interventions for clients with limited likelihood of survival, a mix of ethical considerations, clinical knowledge, and prioritization of care based on systematic and human needs must be considered. While principle systemic before local (life before limb) and applying clinical knowledge to procedural standards are both important factors, the nurse must also consider the hierarchy of human needs when prioritizing interventions. Furthermore, ethical dilemmas often arise in clinical practice, where the dignity and safety of all organisms must be respected. For example, utilitarian philosophers might advocate for actions that promote the greatest happiness for the largest number of people, which can involve tough decisions about resource allocation, like the use of a respirator. Understanding the importance of rapid assessment, using checklists for procedural compliance, dealing with ethical challenges, and always seeking consent for actions like organ or tissue harvesting form part of comprehensive clinical decision-making.
