A nurse is assessing a pregnant client at 28 weeks gestation with a pre-pregnancy BMI of 35 kg/m². Which assessment finding would be most concerning and require immediate follow-up?
1Blood pressure reading of 128/82 mmHg
2Fasting blood glucose level of 95 mg/dL
3Proteinuria of 2+ on urine dipstick with blood pressure of 148/96 mmHg✓ 정답
4Weight gain of 12 pounds since conception
해설
Proteinuria with elevated BP indicates preeclampsia, a serious complication with higher risk in obese pregnant women. Other findings are within normal limits or less urgent.
Core Nursing ExplanationKey Concept Analysis: This question assesses the ability to identify a critical, life-threatening complication of pregnancy—Preeclampsia—and understand the increased risk factors. The client has a pre-pregnancy BMI of 35 kg/m², classifying her as obese, which is a significant risk factor for developing preeclampsia. Preeclampsia is defined by new-onset hypertension (BP ≥140/90 mmHg) and proteinuria (≥1+ on dipstick) after 20 weeks of gestation. It can progress rapidly to eclampsia (seizures) or HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets), threatening both maternal and fetal life.
Answer Rationale: Key Point! The combination of elevated blood pressure (148/96 mmHg) and significant Proteinuria (2+) meets the diagnostic criteria for preeclampsia. In a high-risk patient (obesity), this finding is a medical emergency requiring immediate notification of the provider, further evaluation (e.g., 24-hour urine protein, liver function tests, platelet count), and likely intervention to prevent progression.
Distractor Analysis:
Watch out for confusion! Option 1: A BP of 128/82 mmHg is within the normal range for pregnancy. While it should be monitored, it is not an immediate concern.
Option 2: A fasting blood glucose of 95 mg/dL is normal. Although obesity increases the risk for gestational diabetes mellitus (GDM), this value does not indicate hyperglycemia and is not urgent.
Option 4: A weight gain of 12 pounds at 28 weeks is appropriate. The Institute of Medicine (IOM) guidelines recommend a total weight gain of 11-20 lbs for obese women (BMI ≥30). This finding is expected and not concerning.
Related Concepts: This scenario integrates knowledge of prenatal assessment, risk factor identification (obesity), and the pathophysiology of hypertensive disorders of pregnancy. The nurse's role is critical in early detection through vigilant assessment of blood pressure and urinalysis results.
Concept Summary
Concept
Key Points
Preeclampsia
Hypertension + Proteinuria after 20 weeks. Risk factors: first pregnancy, obesity, chronic hypertension, multifetal gestation.
Obesity in Pregnancy (BMI ≥30)
Major risk factor for preeclampsia, GDM, cesarean delivery, macrosomia, and thromboembolism.
Normal Prenatal Findings
BP <140/90, fasting glucose <95 mg/dL, weight gain per IOM guidelines based on pre-pregnancy BMI.
Nursing Priority
Recognize signs of preeclampsia (headache, visual changes, epigastric pain, edema, hypertension, proteinuria) and act immediately.
Side-by-Side Comparison!
Assessment Finding
Interpretation & Action
Why It's Not the Most Concerning
BP 128/82 mmHg
Normal. Continue routine monitoring.
Does not indicate hypertension.
Fasting Glucose 95 mg/dL
Normal. No indication of GDM.
Within normal limits; not an acute threat.
Proteinuria 2+ & BP 148/96
Preeclampsia.Notify provider STAT, admit for evaluation.
N/A - This is the correct, most concerning finding.
Weight gain 12 lbs at 28 wks
Appropriate for obese BMI. Provide nutritional counseling.
Consistent with recommended guidelines.
Anatomy, Physiology & Pharmacology PointsPathophysiology: Preeclampsia involves generalized vasospasm, leading to hypertension, reduced organ perfusion, and endothelial damage. This damage allows protein to leak into the urine (proteinuria). The placenta is also affected, risking fetal growth restriction.
Pharmacology: First-line treatment for severe hypertension in preeclampsia is Labetalol or Hydralazine. The definitive treatment for preeclampsia is delivery of the fetus and placenta.
Memory TipsMnemonics for Preeclampsia Symptoms: Key Point! Remember "HELLP" for the severe complication: Hemolysis, Elevated Liver enzymes, Low Platelets.
Think "BP + Pee": The two cardinal signs are high Blood Pressure and Protein in the urine (Proteinuria).
High-Frequency NCLEX Topics
Preeclampsia is a High Yield topic. Expect questions on: 1) Identifying risk factors (like obesity), 2) Recognizing assessment findings (BP, proteinuria, reflexes, clonus), 3) Knowing priority interventions (bed rest in left lateral position, administer MgSO₄, monitor for toxicity), and 4) Providing patient education (report headache, visual changes, epigastric pain).
Watch Out for Question Variations!
* Instead of "most concerning finding," the question could ask: "Which finding requires immediate notification of the healthcare provider?" (Same answer).
* It could present a patient with preeclampsia and ask: "What is the priority nursing intervention?" (Answer: Ensure patient safety, prepare for MgSO₄ administration to prevent seizures).
* It could test knowledge of MgSO₄ administration: "The nurse should have which antidote readily available?" (Answer: Calcium gluconate).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse in a prenatal clinic. Maria, a 28-year-old G1P0 at 28 weeks, arrives for her check-up. Her pre-pregnancy weight was 210 lbs at 5'4" (BMI 36). She mentions a slight headache but says it's probably from stress. During your assessment, you obtain the vital signs and urine sample as in the question.
Nursing Intervention Strategy:
1AssessmentImmediately re-check the BP in the other arm with the patient sitting and then in left lateral recumbent position. Assess for other symptoms: severe headache, visual disturbances (blurring, spots), epigastric/RUQ pain, sudden edema in face/hands, hyperreflexia, clonus.
2ActionNotify the physician or midwife immediately with your findings. Do not let the patient leave. This likely warrants hospital admission.
3Planning/ImplementationIf admitted, anticipate orders for: lab work (CBC, liver enzymes, creatinine, 24-hour urine protein), continuous fetal monitoring, IV access, and possibly administration of antihypertensives and MgSO₄ for seizure prophylaxis.
4Patient Education & EvaluationEducate the patient on the signs of worsening preeclampsia. Evaluate the effectiveness of interventions by monitoring BP trends, urine output, deep tendon reflexes, and fetal well-being.
Patient Safety and Precautions:
* Key Point!MgSO₄ Toxicity: If MgSO₄ is administered, monitor closely for signs of toxicity: loss of deep tendon reflexes (first sign), respiratory depression (<12 breaths/min), oliguria (<30 mL/hr), and cardiac arrest. Have calcium gluconate at the bedside as the antidote.
* Contraindication: Do not give diuretics for edema in preeclampsia, as this can worsen the already reduced plasma volume.
Nursing Procedure & Medication FlowProcedure for Managing Suspected Preeclampsia in Clinic:
1. Ensure accurate BP measurement (correct cuff size, patient rested).
2. Obtain clean-catch urine for dipstick protein analysis.
3. Upon identifying hypertension + proteinuria: Stay with patient, place in left lateral position to improve placental perfusion.
4. Activate emergency protocol: Notify provider, prepare for transfer to labor & delivery.
5. Document findings thoroughly and accurately.
A Word from Your Senior Nurse
"Trust your assessment! In prenatal care, you are the first line of defense for two patients—the mother and the baby. A 'slight headache' combined with those numbers is a huge red flag. Never dismiss it. Your quick recognition and action in a case like this can literally save lives by preventing a seizure (eclampsia) or a stroke. When you study, don't just memorize 'BP and proteinuria.' Picture the anxious patient in your clinic chair. Connect the pathophysiology (vasospasm) to the symptom (headache) to your nursing action (calling the doctor). That's how you move from passing a test to being a great nurse."
Preeclampsia — A pregnancy-specific syndrome of new-onset hypertension (≥140/90 mmHg) and proteinuria (≥1+ on dipstick) occurring after 20 weeks of gestation.
Body Mass Index — A measure of body fat based on height and weight. In pregnancy, a pre-pregnancy BMI ≥30 kg/m² (obesity) is a major risk factor for complications.
Proteinuria — The presence of excess proteins, notably albumin, in the urine. A key diagnostic criterion for preeclampsia, indicating glomerular endothelial damage.
Gestational Diabetes Mellitus — Diabetes diagnosed in the second or third trimester of pregnancy that was not clearly overt diabetes prior to gestation. Screened for with a glucose challenge test.
HELLP Syndrome — A severe, life-threatening variant of preeclampsia characterized by Hemolysis, Elevated Liver enzymes, and Low Platelet count.
