A nurse is caring for a client with eclampsia who is having a tonic-clonic seizure.

Which action should the nurse take first?

Headache unrelieved by analgesics.This is because headache is a common symptom of HELLP syndrome, a rare pregnancy complication that can cause high blood pressure, seizures, stroke or liver rupture.HELLP syndrome is a type of preeclampsia and has similar symptoms.

Choice A is wrong because breast engorgement is a normal postpartum condition that occurs when the breasts are full of milk and become swollen and tender.

It is not related to HELLP syndrome.

Choice B is wrong because lochia rubra for 3 days postpartum is a normal finding that indicates the shedding of the uterine lining after delivery.

It is not related to HELLP syndrome.

Choice D is wrong because perineal discomfort is a common postpartum discomfort that results from the stretching and tearing of the perineal tissues during vaginal delivery.

It is not related to HELLP syndrome.

Normal ranges for blood pressure are less than 120/80 mmHg, for platelet count are 150,000 to 450,000 per microliter, and for liver enzymes are 7 to 56 units per liter for AST and 0 to 35 units per liter for ALT.

The correct answer is A and B. A. Serum magnesium level of 8 mg/dL

This statement is correct because a serum magnesium level of 8 mg/dL (6.6 mmol/L) is within the therapeutic range for eclampsia treatment, which is 3.5 to 7 mEq/L (4.2 to 8.4 mg/dL) according to some sources, or 1.5 to 3.5 mmol/L according to others.A serum magnesium level above 8 mEq/L (10 mmol/L) can cause areflexia, respiratory paralysis, and cardiac arrest.

B. Serum calcium level of 7 mg/dL

This statement is correct because a serum calcium level of 7 mg/dL (1.75 mmol/L) is below the normal range of 8.5 to 10.2 mg/dL (2.12 to 2.55 mmol/L), which indicates hypocalcemia.Hypocalcemia is a common side effect of magnesium sulfate therapy, as magnesium competes with calcium for binding sites on plasma proteins and cell membranes, and also inhibits the release of parathyroid hormone.

C. Serum creatinine level of 1.2 mg/dL

This statement is wrong because a serum creatinine level of 1.2 mg/dL (106 umol/L) is within the normal range of 0.6 to 1.3 mg/dL (53 to 115 umol/L) for women.Serum creatinine level reflects kidney function, and renal impairment can affect the clearance of magnesium sulfate and increase the risk of toxicity.

D. Serum potassium level of 3.8 mEq/L

This statement is wrong because a serum potassium level of 3.8 mEq/L (3.8 mmol/L) is within the normal range of 3.5 to 5 mEq/L (3.5 to 5 mmol/L) for adults.Serum potassium level reflects electrolyte balance, and hypokalemia or hyperkalemia can affect cardiac function and muscle contraction.

E. Serum sodium level of 140 mEq/L

This statement is wrong because a serum sodium level of 140 mEq/L (140 mmol/L) is within the normal range of 135 to 145 mEq/L (135 to 145 mmol/L) for adults.Serum sodium level reflects fluid balance, and hyponatremia or hypernatremia can affect brain function and blood pressure.
