A pregnant client at 28 weeks gestation with gestational diabetes mellitus (GDM) comes to the clinic for a routine prenatal visit. Which assessment finding would be most concerning and require immediate intervention?
1Blood glucose level of 140 mg/dL two hours after meals
2Weight gain of 2 pounds since the last visit 2 weeks ago
3Fundal height measuring 26 cm
4Absence of fetal movement for the past 6 hours✓ 정답
해설
Absence of fetal movement for 6 hours in GDM requires immediate intervention due to high risk of fetal compromise. Other findings (elevated glucose, weight gain, fundal height) are expected or manageable with routine care.
Core Nursing Explanation
This question tests the nurse's ability to prioritize assessment findings in a high-risk pregnancy, specifically Gestational Diabetes Mellitus (GDM). The core principle is recognizing signs of Key Point!acute fetal compromise versus findings related to the chronic management of a condition.
Key Concept Analysis: GDM increases the risk of fetal macrosomia (large for gestational age), birth trauma, neonatal hypoglycemia, and, critically, intrauterine fetal demise (stillbirth). The pathophysiology involves maternal hyperglycemia leading to fetal hyperglycemia and hyperinsulinemia, which increases fetal oxygen consumption and can lead to chronic hypoxia. A sudden decrease or cessation of fetal movement is a potential warning sign of acute fetal distress or compromise.
Answer Rationale: Key Point! The absence of fetal movement for 6 hours is a red flag requiring immediate evaluation. While fetal sleep cycles can last up to 40-90 minutes, prolonged absence of movement warrants assessment with a non-stress test (NST) or biophysical profile (BPP) to check for fetal well-being. In a GDM pregnancy, the threshold for concern is lower due to the increased risk.
Distractor Analysis:
Watch out for confusion! A blood glucose of 140 mg/dL 2 hours postprandial is elevated (target is often < 120 mg/dL). However, this is a chronic management issue for GDM, addressed through diet, exercise, or medication adjustment. It does not represent an immediate threat requiring the same level of urgent intervention as absent fetal movement.
Weight gain of 2 lbs in 2 weeks is appropriate for the third trimester. Excessive weight gain might be a concern, but this amount is within normal limits and not an immediate danger.
Fundal height of 26 cm at 28 weeks gestation is expected (the measurement in cm roughly equals the gestational age in weeks, +/- 2 cm). This finding is reassuring, not concerning.
Related Concepts: This question integrates knowledge of GDM complications, normal versus abnormal fetal assessment, and the nursing priority of Airway, Breathing, Circulation (ABCs) applied to the fetus. The fetus's "circulation" and oxygenation status are the priority when threatened.
Concept Summary Gestational Diabetes Mellitus (GDM): Glucose intolerance first recognized during pregnancy. Managed to prevent maternal (preeclampsia, cesarean delivery) and fetal (macrosomia, hypoglycemia, stillbirth) complications.
Fetal Movement Counting (Kick Counts): A method of maternal fetal assessment. "Count-to-Ten": 10 movements in 2 hours is reassuring. Report decreased movement or absence for a concerning period (often defined as >2 hours without movement after 28 weeks).
Priority Setting: Acute, life-threatening signs (potential fetal demise) always take precedence over chronic, stable conditions (elevated glucose).
Side-by-Side Comparison!
Assessment Finding
Interpretation & Action
Rationale
Absent fetal movement >2-6 hrs
Immediate intervention required. Notify provider, prepare for NST/BPP.
Potential sign of acute fetal compromise or distress.
Elevated postprandial glucose (e.g., 140 mg/dL)
Requires follow-up & teaching. Adjust diet/medication plan at next visit.
Chronic issue of glycemic control; not an immediate emergency.
Fundal height lagging >3 cm
Requires further evaluation. Schedule ultrasound to assess fetal growth.
Sign of possible intrauterine growth restriction (IUGR); urgent but not an immediate emergency like absent movement.
Anatomy, Physiology & Pharmacology Points Pathophysiology: Maternal insulin resistance → hyperglycemia → fetal hyperglycemia → fetal pancreatic beta-cell hyperplasia → fetal hyperinsulinemia. Insulin is a growth hormone, leading to macrosomia. Hyperinsulinemia increases fetal metabolic rate and oxygen demand, risking hypoxia.
Fetal Assessment: The Non-Stress Test (NST) monitors fetal heart rate (FHR) accelerations with movement. A reactive NST (2+ accelerations in 20 min) is reassuring. The Biophysical Profile (BPP) uses ultrasound to score fetal breathing, movement, tone, amniotic fluid, and NST.

High-Frequency NCLEX Topics
NCLEX loves to test priority-setting in high-risk obstetrics. You must differentiate between a finding that requires routine monitoring/teaching and one that requires immediate notification and intervention. Fetal well-being (movement, heart rate) is almost always the highest priority over maternal lab values or vital signs unless the mother is unstable.
Watch Out for Question Variations! Shift from Symptom to Intervention: "The nurse notes absent fetal movement. What is the priority action?" (Answer: Notify the healthcare provider and initiate fetal monitoring/NST).
Shift to Postpartum Care: "A newborn of a mother with GDM is jittery and has a glucose level of 30 mg/dL. What is the priority nursing intervention?" (Answer: Feed the newborn with breast milk or formula to correct hypoglycemia).Nursing Clinical Practice GuideClinical Scenario: You are the clinic nurse. Ms. Lee, 28 weeks pregnant with GDM, reports she hasn't felt her baby move since last night (about 8 hours). She says, "I drank some juice and lay on my side like you said, but still nothing."
Nursing Intervention Strategy:
Immediate Assessment: Stay calm but act swiftly. Ask specific questions: "When was the last movement you felt for sure? Have you tried the kick count method? Any vaginal bleeding or pain?"
Action:Do not delay. Immediately notify the obstetrician or midwife. While waiting, assist the client to a left lateral position, apply the external fetal monitor (if available in clinic), and check the FHR.
Preparation: Be prepared to transfer the client to Labor & Delivery (L&D) for a formal NST or BPP. Explain the process to the client to reduce anxiety: "We're going to check the baby's heartbeat and movements closely with a monitor to make sure everything is okay."
Education (After Stabilization): Reinforce kick counts: "Starting at 28 weeks, please do a daily kick count. Lie on your side after a meal, and time how long it takes to feel 10 movements. Call us if it takes longer than 2 hours, or if you notice a significant decrease from the baby's normal pattern."
Patient Safety and Precautions:
Never dismiss a mother's concern about decreased fetal movement. She knows her baby's pattern best.
In GDM, maintain vigilance for other complications like preeclampsia (monitor blood pressure and for proteinuria).
Nursing Procedure & Medication Flow Procedure for Fetal Kick Counts (Maternal Education):
1. Instruct the client to choose a time when the baby is usually active (often after a meal).
2. Have her lie on her left side in a quiet place.
3. She should count each distinct movement (kick, roll, swish).
4. The goal is to feel 10 movements within 2 hours.
5. Document the time it took to reach 10.
6. Report if: It takes >2 hours, movements are significantly less than usual, or there are no movements in a 6-hour period.
Medication in GDM: If diet/exercise fails, insulin is the first-line pharmacologic therapy. Nursing responsibilities include:
- Teaching self-administration of subcutaneous insulin.
- Reinforcing hypoglycemia recognition and treatment (15-15 rule: 15g simple carb, recheck in 15 min).
- Stressing that oral hypoglycemics like glyburide or metformin may be used off-label but insulin does not cross the placenta.
A Word from Your Senior Nurse
"In maternal nursing, you have two patients: the mother and the baby. When a mom tells you her baby isn't moving, your internal alarm bells should ring. Trust her instinct. Acting quickly on decreased fetal movement can literally save a life. When studying, always ask yourself: 'Is this finding a threat to life or limb right now?' If the answer is yes for either patient, that's your priority. This mindset will guide you through countless NCLEX questions and, more importantly, through your real shifts on the antepartum or L&D unit."
Gestational Diabetes Mellitus — Glucose intolerance with onset or first recognition during pregnancy. It results from hormonal changes that cause insulin resistance.
Non-Stress Test — An antepartum test that monitors fetal heart rate (FHR) accelerations in response to fetal movement. A reactive NST (accelerations present) is reassuring of fetal well-being.
Biophysical Profile — An ultrasound assessment that scores five components: fetal breathing, movement, tone, amniotic fluid volume, and NST. A score of 8-10/10 is normal.
Macrosomia — A condition where a newborn is significantly larger than average (birth weight >4000 grams or 8 lbs 13 oz). A common complication of GDM due to fetal hyperinsulinemia.
Intrauterine Fetal Demise — The death of a fetus in the uterus after 20 weeks of gestation. Decreased fetal movement can be a warning sign.
