A nurse is caring for a client following an amniocentesis.
The nurse should observe the client for which of the following complications?

Rationale for Correct Condition

Preeclampsia is characterized by hypertension (≥140/90 mm Hg) and proteinuria (≥300 mg/24 hr) or signs of systemic involvement such as headache and edema. The client’s elevated BP, significant proteinuria, headache, hyperreflexia, and pitting edema strongly indicate preeclampsia. The absence of seizures rules out eclampsia, and the gestational age excludes chronic hypertension with superimposed preeclampsia.

Rationale for Correct Actions

Magnesium sulfate prevents seizures by stabilizing neuronal excitability and reducing cerebral vasospasm. It also lowers BP by promoting vascular relaxation. External fetal monitoring detects fetal distress from utero-placental insufficiency caused by preeclampsia-related hypertension and endothelial dysfunction.

Rationale for Correct Parameters

Blood pressure reflects disease progression and response to antihypertensives. Severe hypertension increases the risk of cerebral hemorrhage and placental abruption. Deep tendon reflexes indicate neurological impairment. Hyperreflexia signals worsening preeclampsia, while absent reflexes may indicate magnesium toxicity.

Rationale for Incorrect Conditions

Gestational hypertension lacks proteinuria and systemic symptoms. Chronic hypertension with superimposed preeclampsia requires a pre-existing hypertensive diagnosis. Eclampsia involves seizures, which the client has not reported.

Rationale for Incorrect Actions

Ampicillin is not indicated without infection. Rh immune globulin is unnecessary without Rh incompatibility. Anticoagulants are not first-line for preeclampsia.

Rationale for Incorrect Parameters

Temperature is not directly related to preeclampsia. Petechiae are signs of coagulopathy, not primary indicators. Pruritus is irrelevant unless liver dysfunction is suspected.

Take-Home Points

• Preeclampsia involves multisystem dysfunction with endothelial damage.
• Magnesium sulfate prevents seizures but must be monitored for toxicity.
• Differentiation from gestational hypertension is crucial for management.
• Fetal monitoring is key to detecting early signs of compromise.

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.
