On speculum examination of the cervix, it is found to be round and smooth. These findings suggest that the patient

- D. is nulliparous.
Correct Answer: D
Rationale: The correct answer is D: is nulliparous. A round and smooth cervix typically indicates that the patient has not given birth before (nulliparous). This is because after vaginal deliveries, the cervix may appear irregular or have scarring. Choice A is incorrect because being a multipar (having multiple births) would likely result in changes to the cervix after birth. Choice C is incorrect because previous vaginal deliveries would usually lead to changes in the cervix as well. Choice B is incomplete and does not provide any relevant information.
