A client is attempting to deliver vaginally despite the fact that her previous delivery was by cesarean birth.
Her contractions are 2-3 minutes apart, lasting from 75 to 100 seconds.
Suddenly, the client complains of intense abdominal pain, and the fetal monitor stops picking up contractions.
The nurse recognizes that which of the following has occurred?

Choice A rationale

A dipstick value of 3+ for protein in the urine is a significant indicator of proteinuria, a key diagnostic criterion for preeclampsia. Preeclampsia is characterized by new-onset hypertension and proteinuria or other signs of end-organ damage in a previously normotensive pregnant woman. A 3+ protein level suggests substantial protein spillage into the urine, necessitating immediate attention to assess the severity of preeclampsia and prevent potential complications for both the mother and the fetus. Normal urine protein is typically negative to trace amounts.

Choice B rationale

Pitting pedal edema at the end of the day can be a common finding in pregnancy due to increased blood volume and pressure on the veins in the legs. While edema can be associated with preeclampsia, it is not a primary diagnostic criterion and can occur in normal pregnancies. Therefore, isolated pedal edema without other signs of preeclampsia is less concerning than significant proteinuria.

Choice C rationale

A blood pressure reading of 138/86 mm Hg is mildly elevated and falls within the range for stage 1 hypertension. While hypertension is a diagnostic criterion for preeclampsia, this isolated reading without a significant increase from baseline or other preeclampsia symptoms may not be the most urgent concern compared to significant proteinuria. Preeclampsia diagnosis requires a blood pressure of ≥140 mm Hg systolic or ≥90 mm Hg diastolic on two occasions at least 4 hours apart after 20 weeks of gestation in a previously normotensive woman.

Choice D rationale

A weight gain of 0.5 kg (approximately 1.1 pounds) over two weeks is within the expected range for weight gain during pregnancy. While rapid or excessive weight gain can be a sign of fluid retention associated with preeclampsia, a modest gain of 0.5 kg over two weeks is not a primary indicator of the condition and is less concerning than significant proteinuria.

Choice A rationale

Absent early decelerations of the fetal heart rate are generally considered a reassuring sign. Early decelerations are a gradual decrease and return of the fetal heart rate associated with uterine contractions, thought to be caused by fetal head compression. Their absence does not typically warrant immediate reporting.

Choice B rationale

A fetal heart rate of 140 beats per minute falls within the normal range for a term fetus, which is typically between 110 and 160 beats per minute. This finding is reassuring and does not require immediate reporting to the provider.

Choice C rationale

Contraction frequency of 2 to 3 minutes apart indicates that the labor is progressing. While the overall pattern of contractions needs to be evaluated in conjunction with other factors like duration and intensity, a frequency within this range is not necessarily a concerning finding that requires immediate reporting on its own.

Choice D rationale

Contraction durations of 95 to 100 seconds are considered prolonged. Normal contraction duration in the active phase of labor typically ranges from 45 to 60 seconds. Prolonged contractions can reduce uterine blood flow and potentially lead to fetal hypoxia, making this a concerning finding that should be promptly reported to the provider for further evaluation.
