Step-by-step explanation:
Before an ultrasound exam for a woman in the 1st trimester of pregnancy, there are several nursing actions that should be taken:
- Ensure a full bladder: A full bladder can push the uterus up, making it easier to view the fetus during the ultrasound.
- Explain the procedure: It is important to explain the ultrasound procedure to the woman, including what to expect and how it will help assess her pregnancy.
- Obtain consent: It is necessary to obtain the woman's informed consent before performing the ultrasound exam.
