NHA Phlebotomy Certification Practice Exam

In what situation can a phlebotomist collect blood from an unconscious patient?

1. During an emergency

2. If a guardian is present

3. Under implied consent

4. With verbal consent

The correct answer is: Under implied consent

Collecting blood from an unconscious patient falls under the principle of implied consent. In medical emergencies, when a patient is unable to provide consent verbally due to their condition, healthcare providers are allowed to assume that the patient would consent to necessary treatment, including blood collection, if they were able to make that decision. This principle is grounded in the ethical obligation to provide care that preserves life and addresses urgent health needs. In situations outside of emergencies or without established implied consent, it would generally not be appropriate to proceed with blood collection without explicit consent from the patient or their legal representative. This is particularly important in maintaining ethical standards and legal compliance in healthcare practices.
