A nurse is caring for a client who is at 36 weeks of gestation.
Which of the following findings should the nurse identify as the priority to assess further?

Fetal hypoxia occurs when oxygen delivery to the fetus is compromised. In this client, the contraction pattern of very frequent, prolonged contractions every 1–2 minutes lasting 90–120 seconds results in uterine tachysystole, which reduces uteroplacental blood flow during contractions. Normal contraction frequency is no more than 5 contractions in 10 minutes. Excessive contractions increase uterine tone, decrease relaxation time, and limit oxygen exchange, causing fetal heart rate changes like late decelerations and minimal variability. This leads to fetal hypoxia, a critical risk in labor complicated by these contraction abnormalities.

Rationale for incorrect Response 1 options:
Abruptio placentae is a sudden placental separation causing bleeding and pain, which is not directly indicated here, as there is no vaginal bleeding or sharp pain described.
Uterine tachysystole describes the contraction pattern itself rather than a complication; it is a cause, not the adverse outcome.
Chorioamnionitis is infection of fetal membranes, usually indicated by fever and uterine tenderness, neither present here.

Rationale for incorrect Response 2 options:
Gestational hypertension contributes to fetal risk but is not the immediate cause of the current fetal distress.
Fetal heart rate variability describes fetal condition but does not cause fetal hypoxia; rather, it signals it.
Intrauterine growth restriction indicates chronic fetal compromise but is not the direct cause of acute fetal hypoxia during labor contractions.

Take home points:

• Uterine tachysystole causes reduced oxygen delivery by limiting uterine relaxation time, risking fetal hypoxia.
• Fetal hypoxia manifests as late decelerations and minimal variability on fetal monitoring.
• Abruptio placentae and chorioamnionitis have distinct clinical signs, which differ from those caused by contraction abnormalities.
• Differentiating causes of fetal distress is vital for timely intervention during labor to prevent adverse outcomes.

Choice A rationale

Increased leukorrhea, or vaginal discharge, is a common and normal physiological finding during pregnancy due to increased estrogen levels and blood flow to the vaginal area. This increase in discharge helps prevent ascending infections. Unless accompanied by itching, odor, or color changes, it typically does not indicate a problem.

Choice B rationale

Urinary frequency is a common symptom in late pregnancy, particularly in the third trimester. It results from the enlarging uterus compressing the bladder, reducing its capacity, and increasing renal blood flow and glomerular filtration rate, leading to increased urine production. It is a normal physiological adaptation.

Choice C rationale

A persistent headache in a pregnant client, especially in the third trimester, is a priority to assess further because it can be a sign of preeclampsia, a serious hypertensive disorder of pregnancy. Other symptoms of preeclampsia include visual disturbances, right upper quadrant pain, and proteinuria. Early identification is crucial for intervention.

Choice D rationale

Insomnia is a common complaint during the third trimester of pregnancy. It can be attributed to various factors such as physical discomfort, frequent urination, fetal movements, anxiety, and hormonal changes. While bothersome, it is generally considered a normal, though often challenging, aspect of late pregnancy.
