Preparing for Ultrasound Scan Examination
Inform the woman that she needs a full bladder for an abdominal ultrasound scan to allow better imaging of the fetus. Position her comfortably, with pillows under her head and knees, while the test is conducted. Apply ultrasonic gel to the abdomen and pass the scanner over it while images are reproduced. The woman and her partner can watch if they wish. The woman should not feel any discomfort. For a transvaginal ultrasound scan, tell the woman that she may either be in a lithotomy position or have her pelvis elevated. These positions are optimal for imaging the pelvic structures. Introduce a transducer with a protective sheath covering into the vagina. If the woman wants to insert it herself, allow her to do so.
