The physician diagnoses a 3-cm cyst in the ovary of a 28-year-old patient. You expect the initial treatment to include
- A. initiating hormone therapy.
- B. scheduling a laparoscopy to remove the cyst.
- C. examining the patient after her next menstrual perio
Correct Answer: C
Rationale: The correct answer is C because examining the patient after her next menstrual period allows for monitoring the cyst's size and nature. This approach is conservative and avoids unnecessary interventions like hormone therapy or surgery. Monitoring the cyst over time can help determine if it is benign or requires further treatment. Initiating hormone therapy (choice A) is not necessary at this point and may not address the cyst. Scheduling a laparoscopy to remove the cyst (choice B) is invasive and premature without first observing the cyst's behavior. Waiting for the next menstrual period allows for a more informed decision-making process based on the cyst's response to hormonal changes.
