Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse in Labor & Delivery. Ms. Jones, 28, G1P0 at 34 weeks, is admitted with BP 168/110, 3+ proteinuria, complaining of a "crushing" headache and seeing spots. During your neurological assessment, you elicit 4+ patellar reflexes and sustained ankle clonus.
Nursing Intervention Strategy:1. Immediate Action & Safety: Stay with the patient. Call for help and the provider STAT. Raise side rails, place the bed in a low position, and have suction and oxygen ready at the bedside. The environment should be quiet and dimly lit.2. Medication Administration: Anticipate and prepare for the provider's order for magnesium sulfate. This typically involves a loading dose (4-6 g IV over 15-20 minutes) followed by a maintenance infusion (1-2 g/hr).3. Ongoing Monitoring: After MgSO₄ initiation, monitor closely every 15-30 minutes initially: Neurological status (headache, vision, DTRs, clonus), vital signs (especially BP and respiratory rate), strict I&O (watch for oliguria), and fetal heart rate (FHR) patterns.4. Patient Education & Support: Explain all procedures calmly. Educate on the purpose of MgSO₄ ("to prevent seizures") and its side effects (flushing, warmth, lethargy). Reinforce the need to report worsening symptoms immediately.
Patient Safety and Precautions:• MgSO₄ Toxicity: The antidote is calcium gluconate (1 g IV push, readily available).• Delivery Preparation: The definitive treatment is delivery. Prepare the patient for likely induction of labor or cesarean section.• HELLP Surveillance: Monitor labs (CBC, liver enzymes, LDH) for progression to HELLP syndrome.
Nursing Procedure & Medication Flow
MgSO₄ Administration & Monitoring Checklist:• Before Infusion: Check baseline DTRs, respiratory rate (>12/min), and urine output (>30 mL/hr).• Loading Dose: 4-6 g in 100 mL NS IVPB over 15-20 min. Monitor for flushing, warmth, nausea.• Maintenance Infusion: 1-2 g/hr via infusion pump. Label the line clearly.• Q1H Monitoring: Respiratory rate, O2 saturation, DTRs (should be 1+ to 2+).• Q4H Monitoring: Serum magnesium level (therapeutic range: 4-7 mg/dL).• Strict I&O: Foley catheter is usually placed. Report urine output < 30 mL/hr (Mg is excreted renally).• Stop Signs (Toxicity): DTRs absent, respiratory rate < 12/min, somnolence, slurred speech. STOP infusion, notify provider, prepare calcium gluconate.
A Word from Your Senior Nurse
"Preeclampsia is one of the most critical conditions you'll manage in obstetrics. Your keen assessment skills are the first line of defense. That hyperreflexia and clonus aren't just checkboxes on a form—they are the patient's body screaming that a seizure is imminent. In clinical practice, never delegate the neurological assessment of a preeclamptic patient. Trust your findings, act swiftly, and always have calcium gluconate at the bedside when MgSO₄ is running. This vigilance saves lives—both the mother's and the baby's."
