What is the primary function of the endometrial layer of the uterus?
- A. Increase in density and content during each menstrual cycle
- B. Prepare to receive and nourish a fertilized ovum (blastocyst)
- C. Produce the hormones that regulate ovulation
- D. Maintain pregnancy
Correct Answer: B
Rationale: The correct answer is B: Prepare to receive and nourish a fertilized ovum (blastocyst). The primary function of the endometrial layer of the uterus is to provide a suitable environment for implantation and nourishment of a fertilized egg. During the menstrual cycle, the endometrial layer thickens in preparation for potential pregnancy. If fertilization occurs, the blastocyst implants into the endometrium for further development. Choices A, C, and D are incorrect as the endometrial layer does not primarily function to increase in density during each cycle, produce ovulation-regulating hormones, or maintain pregnancy, respectively.
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.
