Final answer:
During a postpartum check, the nurse should assist the woman into a lateral position with her upper leg flexed forward to examine her perineum. Washing hands and using sterile gloves is essential, while instrutcing the woman to avoid urinating before the examination is unnecessary.
Step-by-step explanation:
When performing a postpartum check, the nurse should assist the woman into a lateral position with her upper leg flexed forward to facilitate the examination of her perineum. This position allows for better visualization and access to the perineal area. It is important to examine the perineum for any tears or lacerations that may have occurred during childbirth.
The option B, assisting the woman into a supine position with her arms above her head and legs extended, is not the correct position for a postpartum check. This position does not provide adequate access to the perineum or facilitate examination of the perineal area.
In terms of option C, instructing the woman to avoid urinating just before the examination is not necessary. A full bladder does not facilitate fundal palpation, which is the examination of the uterus. In fact, a full bladder can make the examination more uncomfortable and may not provide accurate results.
Option D, washing hands and putting on sterile gloves before beginning the check, is essential and should be followed by the nurse to maintain aseptic technique and prevent the spread of infection.
