A nurse is assessing a client who is 12 hours postpartum and received spinal anesthesia for a cesarean birth.
Which of the following findings requires immediate intervention by the nurse?

Choice A rationale

While documenting findings is a crucial nursing responsibility, a white blood cell count of 28,000 mm³ in a newborn is significantly elevated. The normal range for a newborn's WBC count is typically between 9,000 to 30,000 mm³, but a value at the higher end or exceeding this range warrants further investigation to rule out infection or other underlying conditions. Simply documenting without further action could delay necessary interventions.

Choice B rationale

A WBC count of 28,000 mm³ in a newborn raises suspicion for neonatal sepsis, a serious bloodstream infection. Unit protocols for a sepsis workup typically involve obtaining blood cultures, a complete blood count with differential, and potentially a lumbar puncture and chest X-ray to identify the source and extent of infection. Prompt initiation of these measures is critical for timely diagnosis and treatment, improving the newborn's prognosis.

Choice C rationale

Taking vital signs is a standard nursing assessment, but in the presence of an abnormal lab value suggestive of a serious condition like sepsis, it is insufficient as the sole action. While changes in vital signs can indicate infection, they may not be present in the early stages. Notifying the provider is necessary, but initiating a sepsis workup concurrently based on unit protocol allows for quicker diagnostic evaluation.

Choice D rationale

A heel stick for a bedside blood glucose reading is indicated for assessing hypoglycemia, a common concern in newborns, particularly those at risk. However, it does not directly address the significantly elevated WBC count. While infection can sometimes affect blood glucose levels, this test would not provide information about the potential underlying cause of the leukocytosis.

Choice A rationale

Deep tendon reflexes of +1 are hypoactive reflexes, indicating decreased neurological excitability. In preeclampsia, central nervous system irritability is a key feature, often leading to hyperreflexia, which would be documented as +2, +3, or +4. Therefore, +1 reflexes are inconsistent with preeclampsia.

Choice B rationale

3+ protein in the urine indicates significant proteinuria, which is a hallmark sign of preeclampsia. The kidneys are affected in preeclampsia, leading to increased excretion of protein in the urine.

Choice C rationale

A blood pressure of 148/98 mm Hg is elevated and falls within the diagnostic criteria for preeclampsia, which is hypertension (systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg) that develops after 20 weeks of gestation along with proteinuria or other signs of end-organ damage.

Choice D rationale

Pitting sacral edema, or swelling in the sacral area that leaves a pit when pressed, is a common finding in preeclampsia due to fluid retention and increased capillary permeability.
