해설
Assessing fetal movement is the priority because decreased movement can indicate fetal distress requiring immediate intervention. Anxiety or dietary factors are important but less urgent initial assessments.
When a pregnant client reports sleep disturbance, the nurse must systematically rule out the most urgent physiological threats to maternal-fetal well-being before addressing comfort or lifestyle factors. The principle of airway, breathing, and circulation (ABCs) extends to fetal assessment: a change in fetal movement can be the earliest and sometimes only clinical indicator of fetal compromise.
Why Fetal Movement Takes Priority
The client is at 32 weeks gestation, a point in the third trimester when fetal well-being is monitored largely through maternal perception of fetal activity. A complaint of frequent awakening could be caused by normal discomfort, but it could also be the mother unconsciously responding to a reduction or alteration in fetal movement overnight. Research consistently links poor maternal sleep quality with adverse pregnancy outcomes. A study of 2,210 second-trimester pregnant women found that poor sleep quality, as measured by the Pittsburgh Sleep Quality Index (PSQI), was significantly associated with adverse birth outcomes [3]. Before attributing the awakenings to anxiety, diet, or positioning, the nurse must first ensure the fetus is not in distress. A decrease or sudden change in the frequency and characteristics of fetal movement is a sentinel sign of potential fetal hypoxia or placental insufficiency and demands immediate evaluation via a non-stress test or biophysical profile.
Analysis of Other Options
- Option 1 (Anxiety levels and stress factors): While pregnancy-related anxiety is common and affects sleep, it is a psychosocial concern that, although important, does not take precedence over a potential physiological emergency. A study exploring sleep quality and pregnancy-related anxiety in 313 pregnant women confirmed a correlation between these factors, but this assessment would follow the confirmation of fetal well-being .
- Option 2 (Dietary intake and caffeine consumption): Caffeine is a known stimulant that can disrupt sleep architecture. However, evaluating dietary habits is a health-promotion and comfort intervention. It does not address an immediate threat to the fetus and can be safely deferred until after a reassuring fetal assessment.
- Option 4 (Sleep position and pillow arrangement): Physical discomfort from the gravid uterus is a frequent cause of sleep disruption. An observational analysis using wearable devices on 243 pregnant women tracked daily sleep measures and physical activity, providing insight into sleep metrics across trimesters . While position changes can improve comfort, this intervention is not the priority when a change in the fetal condition must first be excluded.
Pathophysiological Connection
The link between maternal sleep quality and fetal health is bidirectional. Poor sleep quality is linked to increased risks of gestational complications and adverse fetal outcomes, as adequate sleep is crucial for fetal growth and development . A mother waking frequently may be experiencing a physiological response to fetal movement cessation or abnormal patterns. The nurse’s primary responsibility is to assess the most vulnerable patient—the fetus. By evaluating the frequency and characteristics of fetal movement first, the nurse uses the most readily available and non-invasive screening tool for fetal health before escalating to other assessments.

Clinical Guide: Evaluating Sleep Disturbance in Third Trimester
When a pregnant client reports sleep disruption, the nurse must apply a hierarchy of assessment that prioritizes fetal well-being over maternal comfort. A change in fetal movement is a sentinel sign requiring immediate evaluation.
1. Priority Assessment: Fetal Well-Being
Fetal Movement Inquiry: Ask specifically about the frequency, pattern, and strength of fetal movements over the past 24 hours. Any report of decreased or absent movement is an obstetric red flag.
Immediate Actions: If fetal movement is reduced, initiate continuous electronic fetal monitoring (Non-Stress Test) or a Biophysical Profile as per unit protocol. Do not delay for comfort measures.
Rationale: Poor maternal sleep quality has been associated with adverse birth outcomes, and maternal perception of altered fetal activity may be the first indicator of fetal hypoxia or placental insufficiency.
2. Secondary Assessments (After Fetal Status is Confirmed)
Sleep Position: Assess for supine positioning, which can cause aortocaval compression and contribute to restlessness. Recommend left lateral positioning with pillows for support.
Anxiety and Stress: Screen for contributing psychosocial factors using validated tools, but only after physiologic causes are excluded.
Dietary Habits: Evaluate caffeine intake and timing of meals, as these can exacerbate pregnancy-related insomnia.
3. Patient Education
Instruct the client to perform daily fetal kick counts starting at 28 weeks gestation, reporting fewer than 10 movements in 2 hours.
Reinforce that awakening at night should prompt attention to fetal activity, not just repositioning.
Provide anticipatory guidance that sleep disturbances are common but must be reported if accompanied by decreased fetal movement.
Fetal Movement Count — A daily record of fetal kicks or movements used to monitor fetal well-being, typically noting 10 movements within 2 hours.
Non-Stress Test (NST) — A prenatal test that monitors fetal heart rate in response to its own movements to assess oxygenation and placental function.
Biophysical Profile (BPP) — An ultrasound evaluation combining fetal breathing, movement, tone, amniotic fluid volume, and NST to score fetal health.
Placental Insufficiency — A condition where the placenta fails to deliver adequate oxygen and nutrients to the fetus, often presenting as decreased fetal movement.
