The Nightingale Pledge (1893), written by Lystra Gretter and modeled after the Hippocratic Oath, is the ethical code for nurses. Key commitments include:

• Practicing nursing with loyalty and devotion
• Maintaining the highest standards of professional conduct
• Keeping patient information confidential
• Assisting the physician faithfully
• Devoting oneself to the welfare of patients
• Refraining from all harmful or deleterious practices

The Pledge reflects the ethical foundation of nursing practice globally, including Pakistan, where the Pakistan Nursing Council (PNC) upholds professional nursing standards.
