Final answer:
The patient extending their arm and looking away indicates non-verbal consent, which is considered implied consent in this context. Various forms of consent, including informed consent, are essential in clinical settings to ensure patient autonomy and ethical practice.
Step-by-step explanation:
The patient's action of extending their arm and turning their head away indicates non-verbal consent for the procedure about to be conducted by the Certified Phlebotomy Technician (CPCT). This type of consent falls under the broader concept of implied consent, where the patient's behavior signals agreement without a formal written or verbal statement. It is important to note that for more invasive or risk-related procedures, explicit informed consent would be required, detailing the risks, benefits, and alternative options available to the patient.
