When caring for a client with pre-eclampsia, which laboratory result should the nurse report to the physician immediately?
Platelets 50,000/mm.
Hemoglobin 11 grams/dL.
Creatinine 0.3 mg/dL.
Fasting blood glucose 65 mg/dL.
The Correct Answer is A
Choice A rationale
A platelet count of 50,000/mm³ is critically low (normal range is 150,000-450,000/mm³) in a client with pre-eclampsia. Thrombocytopenia is a serious complication of pre-eclampsia and can significantly increase the risk of bleeding and hemorrhage. This finding requires immediate reporting and intervention.
Choice B rationale
A hemoglobin level of 11 grams/dL is within the lower end of the normal range for postpartum women (typically 12-15 g/dL) and is not an immediate concern in the context of pre-eclampsia, unless there is a rapid decline or other concerning symptoms.
Choice C rationale
A creatinine level of 0.3 mg/dL is below the normal range for non-pregnant adults (typically 0.6-1.2 mg/dL) and might be lower in pregnancy due to increased glomerular filtration rate. While kidney function should be monitored in pre-eclampsia, this specific value is not immediately alarming.
Choice D rationale
A fasting blood glucose of 65 mg/dL is within the normal range (typically 70-100 mg/dL) and is not a typical finding that requires immediate reporting in pre-eclampsia, although gestational diabetes can sometimes coexist.

Correct Answer is ["A","B","C","E","F"]
Explanation
Choice A rationale
Hourly monitoring of deep tendon reflexes is crucial in clients receiving magnesium sulfate for severe preeclampsia. Magnesium sulfate acts as a central nervous system depressant, and diminished or absent deep tendon reflexes (normal range: 2+ to 4+) can indicate magnesium toxicity, necessitating immediate intervention to prevent serious complications like respiratory depression.
Choice B rationale
A urinary output of less than 30 mL per hour signals potential renal hypoperfusion, which can be exacerbated by severe preeclampsia and magnesium sulfate administration. Reduced kidney function can lead to the accumulation of magnesium, increasing the risk of toxicity. Prompt notification of the physician allows for timely adjustments in the treatment plan.
Choice C rationale
Calcium gluconate is the antidote for magnesium sulfate overdose. Having it readily available is essential in case the client exhibits signs of magnesium toxicity, such as respiratory depression, severe hypotension, or loss of reflexes. Prompt administration of calcium gluconate can reverse the effects of magnesium and prevent life-threatening complications.
Choice E rationale
Hourly monitoring of intake and output is vital to assess fluid balance and renal function in pregnant clients with severe preeclampsia receiving magnesium sulfate. Accurate measurement helps in detecting oliguria, a sign of worsening preeclampsia or magnesium toxicity, allowing for timely interventions to maintain adequate hydration and prevent complications.
Choice F rationale
Severe preeclampsia significantly impacts both renal and cardiac function due to widespread vasoconstriction and endothelial dysfunction. Close monitoring of these systems through laboratory tests (e.g., serum creatinine, BUN, electrolytes, ECG) and clinical assessments is essential to detect and manage potential complications such as acute kidney injury, heart failure, and arrhythmias.
Correct Answer is D
Explanation
Choice A rationale
Rapid plasma regain is not a standard laboratory test associated with hyperemesis gravidarum. Hyperemesis gravidarum is characterized by severe nausea and vomiting leading to dehydration and electrolyte imbalances.
Choice B rationale
A urine culture is used to detect urinary tract infections, which are not a primary concern in hyperemesis gravidarum unless specifically indicated by symptoms of a UTI.
Choice C rationale
Prothrombin time (PT) and other coagulation studies assess blood clotting. While severe dehydration and malnutrition from hyperemesis gravidarum could theoretically affect coagulation, it is not a routine initial test to anticipate.
Choice D rationale
Urine ketones are a key laboratory finding in hyperemesis gravidarum. Due to persistent vomiting and inadequate oral intake, the body starts to break down fat for energy, leading to ketonuria. The presence of ketones in the urine indicates starvation and the need for intravenous fluids and nutritional support.
