This assignment presents a detailed analysis of ethical and legal principles in nursing through several case studies. The first case study involves a 15-year-old girl seeking advice on morning-after pills, highlighting the health professional's duty to maintain confidentiality, provide support, and navigate legal issues related to underage sexual activity. The second case study addresses a resource allocation dilemma, where a single ventilator must be assigned between two patients with differing survival chances and personal responsibilities, emphasizing the need for ethical decision-making based on multiple factors. The final case examines a patient with Motor Neuron Disease who previously declined further treatment, challenging healthcare professionals to balance the patient's prior wishes with current family desires for continued care. The report concludes that ethical and legal principles are crucial for healthcare professionals, fostering trust and supporting patients while avoiding potential negative consequences. The assignment provides a robust exploration of the complexities inherent in nursing ethics and legal compliance.
