Which of the following is a crucial verification step before surgery?

Confirming the patient's identity is a crucial verification step before surgery because it ensures that the correct patient is receiving the appropriate procedure. This step is vital for patient safety and is part of a broader strategy known as the "surgical safety checklist." By verifying the patient's identity, healthcare providers help prevent errors that could lead to serious consequences, such as performing surgery on the wrong patient or wrong site.

While checking the patient’s weight, revising pre-op instructions, and retrieving the patient’s previous records may all be important in their own right, they do not specifically address the immediate and critical need to ensure that the correct individual is being treated on the day of surgery. Identifying the patient accurately helps to safeguard not only the surgical outcome but also the overall trust in the healthcare system.
