(select all that apply) A nurse is reviewing the laboratory results of a client with eclampsia who is receiving magnesium sulfate.

Which of the following values should the nurse report to the provider? (Select all that apply.)

Serum magnesium level of 8 mg/dL

Serum calcium level of 7 mg/dL

Serum creatinine level of 1.2 mg/dL

Serum potassium level of 3.8 mEq/L

Serum sodium level of 140 mEq/L

Answer and Explanation

Correct Answer : A,B

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.

Correct Answer is A

Explanation

Urinary output of 100 mL in 4 hr is an indication of magnesium sulfate toxicity.Magnesium sulfate is used to prevent seizures in women with severe preeclampsia or eclampsia.Taking too much magnesium can be life-threatening to both mother and child.

Choice B is wrong because

Choice C is wrong because patellar reflex of +2 is normal and not a sign of toxicity.Loss of deep tendon reflexes can occur with magnesium overdose.

Choice D is wrong because serum magnesium level of 4 mEq/L is normal and not a sign of toxicity.Toxic levels are usually above 8 mEq/L.

A. The client has no seizures B. The client has a diuresis C. The client has improved fetal movement D. The client has increased platelet count

Correct Answer is A

Explanation

The client has no seizures.Magnesium sulfate therapy is used to prevent seizures in women with preeclampsia and eclampsia.Seizures are a life-threatening complication of eclampsia and indicate a failure of therapy.

Choice B is wrong because diuresis is not a goal of magnesium sulfate therapy.Diuresis may indicate fluid overload or renal impairment, which are complications of preeclampsia and eclampsia.

Choice C is wrong because improved fetal movement is not a direct outcome of magnesium sulfate therapy.Fetal movement may be affected by many factors, such as gestational age, maternal position, and fetal well-being.

Choice D is wrong because increased platelet count is not a result of magnesium sulfate therapy.Platelet count may be decreased in preeclampsia and eclampsia due to disseminated intravascular coagulation, which is a serious complication that requires prompt treatment.

Normal ranges for blood pressure are less than 140/90 mm Hg, for proteinuria are less than 300 mg/24 hours, for platelet count are 150,000 to 400,000/mm3, and for serum magnesium are 1.5 to 2.5 mEq/L.
