During a routine prenatal visit at 32 weeks gestation, a nurse notes which assessment finding as most concerning, requiring immediate further evaluation?
1Fetal heart rate of 150 beats per minute with good variability
2Fundal height measuring 30 cm
3Maternal weight gain of 2 pounds since the last visit 4 weeks ago
4Absence of fetal movement for the past 24 hours✓ 정답
해설
Absence of fetal movement for 24 hours at 32 weeks is critical and may indicate fetal distress, requiring immediate evaluation. Other findings (FHR 150 bpm with variability, fundal height 30 cm, weight gain 2 lbs) are normal or less urgent.
Core Nursing ExplanationKey Concept Analysis: This question assesses the nurse's ability to identify a critical sign of potential fetal compromise during the third trimester of pregnancy. The core principle is Key Point!Fetal movement is a primary indicator of fetal well-being. A significant decrease or cessation of movement can be an early warning sign of fetal distress, hypoxia, or other complications, necessitating urgent intervention to assess fetal status and potentially prevent stillbirth.
Answer Rationale: The correct answer is Absence of fetal movement for the past 24 hours. By 32 weeks gestation, the fetus has established regular sleep-wake cycles, and the mother should perceive consistent, daily fetal movement. Key Point! The complete absence of perceived movement over a 24-hour period is a red flag that requires immediate evaluation, typically with a non-stress test (NST) or biophysical profile (BPP), to rule out fetal distress or demise. This finding takes precedence over all other routine assessment data.
Distractor Analysis:
Watch out for confusion! Option ①: A fetal heart rate (FHR) of 150 bpm with good variability is a reassuring finding, indicating a normal, reactive fetal heart pattern. Variability is a key sign of fetal CNS integrity.
Watch out for confusion! Option ②: A fundal height of 30 cm at 32 weeks gestation is within the expected normal range (fundal height in cm often corresponds roughly to gestational age in weeks from 20-34 weeks, with a variation of +/- 2 cm). This finding is not concerning.
Watch out for confusion! Option ③: A maternal weight gain of 2 pounds over 4 weeks in the third trimester is within recommended guidelines (approximately 1 lb/week in the 2nd and 3rd trimesters). This is a normal finding and not an immediate concern.
Related Concepts: This question integrates knowledge of antenatal fetal assessment, normal pregnancy parameters, and priority-setting in nursing. It underscores the nurse's role in patient education regarding "kick counts" and the critical importance of reporting decreased fetal movement promptly.
Concept Summary
Concept
Description
Clinical Implication
Fetal Movement (FM)
Maternal perception of fetal kicks, rolls, and stretches. A sign of fetal CNS function and well-being.
Decreased or absent FM is a potential sign of fetal hypoxia/distress. Requires immediate evaluation.
Non-Stress Test (NST)
Primary test to evaluate fetal heart rate (FHR) in response to fetal movement.
A "reactive" NST (FHR accelerations with movement) is reassuring. Used to assess fetal status when concerns like decreased FM arise.
Fundal Height
Measurement from symphysis pubis to top of uterus (fundus).
Should correlate with gestational age (±2 cm). Used to screen for growth abnormalities (IUGR, macrosomia).
Antepartum Fetal Surveillance
Monitoring techniques to assess fetal well-being before labor.
Includes NST, BPP, contraction stress test (CST). Initiated for high-risk pregnancies or concerning signs like decreased FM.
Side-by-Side Comparison!
Assessment Finding
Normal / Reassuring
Concerning / Requires Action
Fetal Heart Rate (FHR)
110-160 bpm, good variability, accelerations with movement.
Bradycardia (<110), tachycardia (>160), absent/minimal variability, late or variable decelerations.
Fetal Movement
Consistent pattern, mother feels at least 10 movements in 2 hours (kick count).
Significant decrease from baseline or absence of movement for 12-24 hours.
Fundal Height
Matches gestational age in weeks (± 2 cm) from 20-34 weeks.
Measurements >3-4 cm above or below expected (suggests polyhydramnios, IUGR, incorrect dates, multiples).
Maternal Weight Gain
Total 25-35 lbs for normal BMI. ~1 lb/week in 2nd/3rd trimesters.
Sudden excessive gain (≥2 lbs/week) may indicate preeclampsia. Inadequate gain may indicate nutritional deficit or IUGR.
Anatomy, Physiology & Pharmacology Points
Physiology: Fetal movement is controlled by the developing central nervous system. Adequate movement requires sufficient oxygen and nutrient delivery via the placenta. Hypoxia can lead to decreased fetal activity as a protective mechanism to conserve energy.
Placental Function: The placenta is the lifeline. Any compromise (abruption, insufficiency) can reduce oxygen transfer, leading to decreased fetal movement and changes in FHR patterns.
Patient Education Focus: Teach the "Count-to-10" method: Note the time it takes to feel 10 distinct movements. Should occur within 2 hours. Report immediately if it takes longer or if movements stop.
Memory Tips
Mnemonic: "MOVE it or LOSE it!" – Missing fetal mOVEment means you might LOSE time to help the baby. Act fast!
Association: Think of fetal movement like a "fetal vital sign." Just as you would be alarmed by the absence of a pulse or respirations in a patient, be alarmed by the absence of fetal movement.
High-Frequency NCLEX Topics
This is a classic priority-setting and "most concerning" question. The NCLEX-RN loves to test your ability to sift through normal and abnormal data to identify the finding that represents the greatest immediate threat to patient (or fetal) safety. Always ask yourself: "Which finding, if ignored, could lead to the worst outcome in the shortest time?"
Watch Out for Question Variations!
Shift from "Finding" to "Intervention": "The nurse notes absence of fetal movement for 24 hours. What is the priority nursing action?" (Answer: Initiate fetal monitoring/NST per protocol and notify the provider immediately.)
Shift to Patient Education: "A client at 32 weeks asks, 'When should I call the clinic about the baby's movements?' What is the nurse's best response?" (Answer: "Call if you notice a significant decrease in movement or if you don't feel at least 10 movements in 2 hours.")
Adding Comorbidities: The scenario could involve a patient with gestational diabetes or hypertension, making the finding of decreased fetal movement even more critical.
Nursing Clinical Practice GuideClinical Scenario: Maria, a 32-year-old G2P1 at 32 weeks gestation, presents for her routine prenatal visit. She appears anxious and tells you, "I haven't felt the baby move at all since yesterday morning. I kept waiting, thinking she was just sleepy, but I'm really worried now."
Nursing Intervention Strategy:
Immediate Assessment & Action:
Do not delay. This is not a "wait and see" situation. Immediately escort the patient to an exam room.
Perform a quick set of vital signs on the mother (BP, pulse).
Using a Doppler or fetoscope, attempt to auscultate the fetal heart rate (FHR). Key Point!Finding a FHR does NOT rule out the need for further testing. It is reassuring but does not explain the absence of movement. The priority is a comprehensive fetal assessment.
Notify the provider (CNM or MD) immediately while preparing for further evaluation.
Comprehensive Evaluation:
The standard next step is a Non-Stress Test (NST). Apply the external monitors (tocodynamometer for contractions, ultrasound transducer for FHR).
Observe for a reactive NST: two or more FHR accelerations of at least 15 bpm for 15 seconds within a 20-minute period, associated with fetal movement.
If the NST is non-reactive, a Biophysical Profile (BPP) (ultrasound assessment of fetal movement, tone, breathing, amniotic fluid volume, and NST) is typically ordered.
Support & Education:
Provide emotional support. Acknowledge the mother's concern and validate that she did the right thing by reporting it.
Re-educate on the importance of daily fetal kick counts and the specific instructions for her to follow at home.
Patient Safety and Precautions:
Never dismiss a mother's report of decreased fetal movement. Maternal perception is a highly sensitive indicator.
Understand that a reactive NST is very reassuring for fetal well-being for the next week, but the mother should continue daily kick counts.
If the evaluation indicates fetal compromise (non-reactive NST, low BPP score), be prepared for possible emergency delivery. The nurse's role includes preparing the patient for possible hospitalization, steroid administration for fetal lung maturity if <37 weeks, and potential cesarean section.
Nursing Procedure & Medication FlowProcedure: Assisting with a Non-Stress Test (NST)
Explain the procedure to the patient.
Position the patient in a semi-Fowler's or lateral tilt position to prevent supine hypotension.
Apply belts: Tocodynamometer over the uterine fundus; Ultrasound transducer over the location of the fetal back (where FHR is loudest).
Give the patient an event marker to press each time she feels fetal movement.
Monitor for 20-40 minutes. Document FHR baseline, variability, presence of accelerations/decelerations, and any uterine activity.
Interpret results with the provider: Reactive vs. Non-reactive.
A Word from Your Senior Nurse
"Trust your gut and trust the mother's gut! In obstetrics, the patient's report of 'something doesn't feel right' or 'the baby isn't moving' is one of the most powerful assessment tools we have. It's our job to take that concern seriously and act swiftly. On the NCLEX and in real life, prioritizing the unexpected absence of a life sign (like fetal movement) over routine, normal findings is a critical thinking skill that saves lives. Remember, you are the advocate for two patients—always err on the side of caution for the baby's well-being."
