Dichorionic-diamniotic twins result from separation of embryonic cells at the:
- A. Four-cell stage
- B. Blastocyst stage
- C. Implantation stage
- D. Trilaminar disc stage
Correct Answer: A
Rationale: The correct answer is A: Four-cell stage. Dichorionic-diamniotic twins occur when the embryo splits into two separate embryos very early in development, typically at the four-cell stage. At this stage, each embryo will have its own chorion and amnion, leading to separate placentas and amniotic sacs. Choices B, C, and D occur later in development and do not result in the formation of two separate embryos with their own chorion and amnion, making them incorrect for the scenario of dichorionic-diamniotic twins.

A postpartum patient who has had a vaginal birth asks the nurse, I was wondering if my cervix will return to its previous shape before I had the baby? Which is the best response by the nurse?
- A. The cervix will now have a slit-like shap
- C. The cervix will be round and smooth after healing occurs.
- D. The cervix will remain 50% effaced now that you have had a baby.
Correct Answer: A
Rationale: The correct answer is A: The cervix will now have a slit-like shape. After giving birth, the cervix undergoes changes in shape and size to adapt to the delivery process. It becomes slit-like instead of round to allow for easier dilation in future pregnancies. This response is correct as it addresses the anatomical changes that occur postpartum.
Choice B is incorrect because it does not provide an explanation of the postpartum cervix shape changes.
Choice C is incorrect because it describes the cervix in a way that does not reflect the usual postpartum changes.
Choice D is incorrect because it refers to effacement, which is the thinning of the cervix during labor and not a permanent change postpartum.
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.
