The labor and delivery nurse caring for a client at 39 weeks gestation notes that the fetal heart tone is heard most loudly and clearly when auscultated in the upper right abdominal quadrant above the umbilicus.
What is the nurse's best interpretation of this finding?

Choice A rationale

Methylergonovine is an oxytocic medication that stimulates smooth muscle contraction of the uterus. While it can cause vasoconstriction and potentially lead to an increase in blood pressure, this is a potential side effect, not the intended therapeutic effect indicating the medication's effectiveness in the postpartum period. The primary goal is uterine contraction to control postpartum bleeding.

Choice B rationale

Breast pain is related to engorgement and milk production, not directly influenced by methylergonovine's action on the uterus. The medication's effectiveness is assessed by its impact on uterine tone and bleeding, not breast comfort. Therefore, the absence of breast pain does not indicate that the methylergonovine has been effective.

Choice C rationale

Methylergonovine is given to decrease postpartum bleeding by promoting uterine contraction, which helps to compress the blood vessels at the placental site. An increase in lochia (postpartum vaginal discharge) would suggest that the medication is not effective in achieving its intended therapeutic outcome of reducing hemorrhage.

Choice D rationale

Methylergonovine's primary therapeutic effect in the postpartum period is to stimulate uterine smooth muscle contraction, leading to a firm fundus. A firm fundus indicates that the uterus is contracting effectively, which helps to compress blood vessels at the placental site and control postpartum bleeding. This is the desired outcome of methylergonovine administration.

• White blood cell count: Expected—mild leukocytosis is normal postpartum due to physiological stress.
• Blood clot size: Expected—small clots, like a pea-sized clot, are common and not concerning unless excessive bleeding occurs.
• Uterine findings: Expected—firm and midline uterus indicating effective involution.
• Lochia findings: Expected—progressing normally without signs of infection (no foul odor).
• Calf findings: Expected—a single varicose vein without tenderness or swelling is not concerning.
• Blood pressure: Expected—within normal postpartum range.
