A medical assistant is preparing to perform an EKG. The assistant needs to shave the area to prevent interference with the electrodes. Which of the following types of consent should the assistant obtain prior to shaving the patient?

Expressed consent refers to a clear, verbal, or written agreement from the patient regarding a specific treatment or procedure. While this type of consent can be applicable, it does not encompass the detailed information and understanding required for procedures like shaving before an EKG.

Written consent indicates a formal agreement documented on paper, which may be required for certain procedures. However, the context of preparing for an EKG does not necessarily demand written consent; rather, the emphasis is on the patient’s understanding of the procedure, which is captured under informed consent.

Implied consent occurs when a patient’s actions suggest agreement to a procedure without explicit verbal or written consent. In medical settings, this may apply in emergencies where immediate action is necessary. However, shaving the patient for an EKG is not an emergency situation and requires a more thorough explanation, making informed consent the appropriate choice.
