What term best describes the permission for patient care that is understood through actions rather than spoken or written confirmation?

The term that best describes the permission for patient care understood through actions rather than spoken or written confirmation is implied consent. This type of consent is generally recognized in situations where it is clear that the patient agrees to receive care through their behavior or actions. For example, if a patient who is conscious and responsive extends their arm for an injection, their action signifies that they consent to the procedure, even if they do not verbally express it.

Implied consent is typically applicable in emergency situations where a patient's immediate treatment is necessary, and waiting for explicit consent could jeopardize their health. It is based on the principle that individuals would consent to necessary medical care if they fully understood the situation.

In contrast, informed consent involves a clear understanding and acknowledgment of the treatment, risks, and benefits, which is usually communicated verbally or in writing. Expressed consent refers to clear and direct agreement from the patient, often provided verbally or through a signed document. Non-verbal consent, while it may seem similar, is not a widely recognized term in medical practice; thus, it does not accurately capture the established concepts of consent used in healthcare.
