The transducer covered with a condom and gel will be inserted into your vagina. This is because a transvaginal ultrasound is an internal scan of the female reproductive organs that involves inserting a small ultrasound probe into the vagina to produce images of the cervix, uterus, fallopian tubes and ovaries.

Choice A is wrong because a full bladder is not necessary for a transvaginal ultrasound, unlike an abdominal ultrasound.

Choice B is wrong because the client does not need to wear loose-fitting clothing or lie on their side during the procedure. They will lie on their back with their knees bent and their feet in stirrups. 

Choice C is wrong because the gel will not be applied on the abdomen, but on the transducer that will be inserted into the vagina.

Normal ranges for transvaginal ultrasound vary depending on the reason for the scan and the stage of pregnancy or menstrual cycle.

However, some general parameters are:

• The uterus should measure about 7.5 x 4.5 x 3 cm and have a smooth contour and uniform echogenicity.

• The endometrium should measure less than 4 mm in postmenopausal women, 2-4 mm in early proliferative phase, 6-10 mm in late proliferative phase, and 10-16 mm in secretory phase.

• The ovaries should measure about 3 x 2 x 1.5 cm and contain multiple small follicles.

• The fallopian tubes should not be visible unless they are dilated or contain fluid.
