NHA Phlebotomy Certification Practice Exam

What type of consent is indicated when a patient extends his arm for a blood draw?

1. Written consent

2. Informed consent

3. Implied consent

4. Verbal consent

The correct answer is: Implied consent

When a patient extends their arm for a blood draw, it demonstrates a non-verbal indication of approval for the procedure. This scenario aligns with implied consent, as the patient's actions suggest they agree to the procedure without needing a formal written or verbal agreement. Implied consent is often observed in situations where the actions of the patient clearly indicate that they understand the procedure and are willing to proceed, even if they do not explicitly state it. In a clinical context, implied consent is commonly accepted in quick, routine procedures where the patient is already familiar with the process and has not indicated any objection. While informed and verbal consents are crucial in more complex or invasive medical situations, the simple act of extending an arm for a blood draw conveys the patient’s tacit permission for the phlebotomy to occur.
