How is an internal examination performed within 40 weeks of pregnancy?

The main examinations during pregnancy within 40 weeks include ultrasound, fetal heart rate monitoring, routine blood tests, blood pressure measurement, weight check, routine urine test, electrocardiogram (ECG), and others. These examinations should be conducted at a正规 hospital. Taking abdominal ultrasound as an example, the specific procedure is as follows:

1. The pregnant woman registers at the registration desk or self-service machine, then visits the assigned department to see a doctor, who will issue an ultrasound examination request based on her condition.

2. Before the examination, the pregnant woman needs to hold urine to ensure the bladder is adequately filled.

3. Upon entering the examination room, the pregnant woman lies flat on her back and removes any clothing covering the abdomen.

4. During the examination, medical staff apply some coupling gel to the lower abdomen of the pregnant woman and place the ultrasound probe on the abdominal wall.

5. The healthcare provider moves the probe across the pregnant woman's abdomen to observe detailed conditions inside the uterine cavity.

6. After the examination, the pregnant woman is given tissues to wipe off the gel, then gets dressed and leaves the examination table.

During abdominal ultrasound, the pregnant woman should stay relaxed and avoid excessive mental stress, while also maintaining good personal hygiene.
