Sample item

Which ultrasound feature is used to confirm an intrauterine early pregnancy?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Gestational sac with yolk sac within the uterine cavity

A yolk sac within an intrauterine gestational sac confirms an intrauterine pregnancy, whereas an empty sac-like structure may require follow-up correlation.

Option by option

  • A. Gestational sac with yolk sac within the uterine cavity (correct)

    Correct: a yolk sac within the uterus is definitive evidence.

  • B. A full urinary bladder only

    Bladder filling improves views but is not diagnostic.

  • C. Free fluid alone in the pelvis

    Free pelvic fluid is nonspecific and can be concerning.

  • D. A thickened endometrium without a sac

    Endometrial thickening alone does not confirm location.
