Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse on the Labor & Delivery unit. A 32-year-old G2P1 at 32 weeks with a dichorionic-diamniotic twin pregnancy is admitted for evaluation of headaches and swelling. Her initial BP is 158/106. A stat urinalysis shows 3+ protein.
Nursing Intervention Strategy:
1. Assessment: Place the patient in a left lateral recumbent position to improve placental perfusion. Obtain a full set of vital signs. Perform a focused neurological assessment (headache? visual changes? hyperreflexia? clonus?). Assess for epigastric or RUQ pain. Monitor fetal heart rates and uterine activity continuously.
2. Planning & Implementation: Initiate seizure precautions (padded side rails, suction equipment at bedside, O2 ready). Administer magnesium sulfate via IV infusion pump as ordered. Monitor deep tendon reflexes (patellar), respiratory rate, and urine output hourly. Administer antihypertensive medication (e.g., labetalol IV push) as ordered for sustained severe-range BP. Strict I&O. Prepare for the possibility of urgent delivery via cesarean section.
3. Evaluation: Evaluate for effectiveness of interventions: Is BP decreasing to a safe range? Are neurologic symptoms resolving? Is the patient seizure-free? Are fetal heart tracings reassuring? Monitor for signs of MgSO4 toxicity.
Patient Safety and Precautions:
* Key Point! Magnesium Sulfate: It is a high-alert medication. Always use an IV pump. Have calcium gluconate (the antidote) readily available at the bedside. Stop the infusion if respiratory rate is < 12/min or urine output is < 30 mL/hr.
* Do not leave the patient unattended. A quiet, dimly lit room can help prevent seizure triggers.
* Avoid Watch out for confusion! administering diuretics for edema; in preeclampsia, edema is due to vascular leak, not fluid overload, and diuretics can worsen placental perfusion.
Nursing Procedure & Medication Flow
MgSO4 Administration (Loading & Maintenance):
1. Loading Dose: Often 4-6 grams IV over 15-20 minutes. Monitor closely for flushing, feeling of warmth, nausea.
2. Maintenance Dose: Typically 1-2 grams/hour via IV infusion pump.
3. Nursing Checks Q1H: Respiratory rate (>12), Patellar deep tendon reflexes (present), Urine output (>30 mL/hr), Level of consciousness.
4. Action for Toxicity: STOP infusion. Administer calcium gluconate 1 gram IV push over 3 minutes as ordered. Support airway and breathing.
A Word from Your Senior Nurse
"Managing a patient with severe preeclampsia is one of the most critical skills in obstetric nursing. Your vigilance is what stands between stability and crisis. Remember, your assessment is key — that severe headache isn't 'just a headache'; it's a red flag for rising intracranial pressure. When you see that BP spike and proteinuria, your brain should immediately switch to 'seizure precaution mode.' On the NCLEX, they're testing your ability to make that same rapid, clinical judgment. Connect the dots: high-risk pregnancy (twins) + hypertension + proteinuria = sound the alarms. This isn't just about passing a test; it's about being the calm, competent nurse who knows how to protect two (or three!) lives at once."
