A nurse is reviewing a client's rubella titer of 1:8 at her second prenatal visit.
Which of the following statements by the nurse is appropriate?

1. Administer magnesium sulfate bolus: Anticipated. Magnesium sulfate is the drug of choice to prevent seizures in severe preeclampsia or eclampsia. The client shows signs of severe preeclampsia (hypertension, headache, visual disturbances, hyperreflexia, clonus, epigastric pain), so a magnesium sulfate bolus is appropriate to reduce CNS irritability and prevent eclamptic seizures.
2. Insert an indwelling urinary catheter: Anticipated. Monitoring urine output is essential in hypertensive disorders of pregnancy to assess kidney function and fluid balance. The client’s urine output (25–55 mL/hr) is borderline low (normal >30 mL/hr), so catheter insertion allows accurate measurement.
3. Initiate intravenous (IV) fluids: Contraindicated. In preeclampsia, patients often have intravascular volume depletion with risk of pulmonary edema due to increased capillary permeability. IV fluids should be carefully restricted to avoid fluid overload, so routine IV fluid initiation is contraindicated unless hypovolemia or dehydration is confirmed.
4. Administer nifedipine 30 mg intermittent IV bolus: Contraindicated. Nifedipine, a calcium channel blocker, is given orally for hypertension in pregnancy, but intermittent IV bolus administration is not recommended because it can cause abrupt hypotension and fetal distress.
5. Begin intermittent electronic fetal monitoring: Anticipated. Continuous or intermittent fetal monitoring is critical for detecting fetal distress, especially in high-risk pregnancies with maternal hypertension and irregular contractions, ensuring timely intervention if needed.

The client is at greatest risk for developing Endometritis as evidenced by the client’s Lochia characteristics.

Rationale for correct answers:
Endometritis is a postpartum uterine infection commonly occurring after cesarean birth due to ascending bacterial contamination. The client’s foul-smelling lochia is a hallmark sign, indicating infection of the uterine lining. Normally, lochia is odorless and changes from red to serous and then to white over weeks postpartum. The elevated WBC count (18,000/mm³; normal 5,000–15,000/mm³) supports infection but is nonspecific. The firm uterine tone reduces likelihood of postpartum hemorrhage. Urinalysis positive for bacteria suggests UTI but does not explain uterine signs. Hence, lochia changes are the most direct indicator of endometritis.

Rationale for incorrect Response 1 answers:
Postpartum hemorrhage typically involves heavy bleeding, uterine atony, or a rapidly dropping hematocrit, none of which is reported here. Urinary tract infection is suggested by urinalysis but does not account for uterine tenderness or foul lochia. Deep vein thrombosis would present with limb swelling, pain, and possible fever but no uterine or lochia changes.

Rationale for incorrect Response 2 answers:
Urinalysis positive for bacteria points to UTI but not uterine infection. Elevated WBC count indicates infection or inflammation but lacks specificity for endometritis versus other infections. Uterine tone is firm here, making hemorrhage or uterine atony unlikely and less relevant to infection diagnosis.

Take home points:

• Endometritis often presents postpartum with foul-smelling lochia and elevated WBC.
• Foul-smelling lochia is a critical clinical sign distinguishing endometritis from other postpartum complications.
• Positive urinalysis suggests UTI, a separate postpartum infection that requires differentiation.
• Uterine tone helps rule out hemorrhage and guides diagnosis of infection versus atony.
