Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: C

Rationale: The patient has shown consent through their actions, such as rolling up their sleeve and positioning their arm, indicating willingness to undergo the procedure without explicitly stating it. This demonstrates implied consent, where consent is inferred from behavior rather than verbal or written agreement.

Option A, expressed consent, requires a clear verbal or written agreement, which is not present here. Option B, verbal consent, also necessitates spoken agreement, which the patient did not provide. Option D, informed consent, involves understanding the procedure and its risks, which is not applicable in this scenario since the patient did not receive detailed information beforehand.
