A nurse is preparing to assess the uterine fundus of a client in the immediate postpartum period.
When the nurse locates the fundus, she notes that the uterus feels soft and boggy at midline.
Which of the following nursing interventions would be most appropriate initially?

Choice A rationale

Supine positioning can compress the vena cava, leading to decreased venous return, reduced cardiac output, and potential maternal hypotension, which can compromise fetal oxygenation. Alternative positions like lateral or semi-recumbent are generally preferred during labor to optimize blood flow.

Choice B rationale

Assessing anesthesia or pain level every 30 minutes is crucial in the active phase of labor to evaluate the effectiveness of pain management interventions and the client's comfort. This frequent monitoring allows for timely adjustments to the pain management plan based on the client's subjective experience and physiological responses.

Choice C rationale

While assessing vaginal bleeding and the fundus is important in the postpartum period to monitor for uterine involution and hemorrhage, it is not the priority during the active phase of labor. The focus during active labor is on maternal and fetal well-being during the labor process itself.

Choice D rationale

Continuous or intermittent oxygen saturation monitoring may be indicated based on the client's condition and fetal heart rate patterns, but it is not a routine assessment every half hour for all clients in active labor. It is typically reserved for situations of suspected maternal hypoxemia or fetal distress.

Rationale for Correct Condition

Preterm labor is defined as the onset of regular contractions leading to cervical change before 37 weeks of gestation. This client’s symptoms, including uterine contractions every 4–5 minutes, cervical effacement of 50%, a positive fetal fibronectin test, and shortened cervical length, strongly indicate preterm labor rather than pyelonephritis, placental abruption, or cervical insufficiency.

Rationale for Correct Actions

Magnesium sulfate functions as a tocolytic, suppressing contractions by inhibiting calcium influx in myometrial cells, thereby delaying preterm birth and reducing neonatal complications. Betamethasone accelerates fetal lung maturity by increasing surfactant production, reducing the risk of neonatal respiratory distress syndrome if preterm delivery occurs.

Rationale for Correct Parameters

Cervical effacement is a direct indicator of labor progression, showing changes in cervical thinning that accompany dilation. Monitoring effacement allows assessment of tocolytic effectiveness. Contraction frequency reveals labor severity and the response to magnesium sulfate. Persistent contractions despite treatment indicate the need for additional interventions.

Rationale for Incorrect Conditions

Pyelonephritis causes systemic symptoms like fever, flank pain, and bacteremia rather than uterine contractions and cervical changes. Placental abruption typically presents with painful vaginal bleeding and uterine tenderness, which are absent here. Cervical insufficiency is painless and lacks regular contractions, with cervical changes occurring silently rather than progressively.

Rationale for Incorrect Actions

Urine culture identifies infection but does not directly treat preterm labor. RhoGAM is necessary for Rh-negative individuals, which is irrelevant in this case. IV hydration may help with contractions but is not a primary intervention.

Rationale for Incorrect Parameters

Flank pain suggests pyelonephritis rather than preterm labor. Vaginal bleeding is associated with abruption or miscarriage, not preterm labor without cervical rupture. Fetal heart rate variability is useful in fetal assessment but does not directly indicate labor progression.
