(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
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 D
Explanation
“I should take a baby aspirin every day as prescribed.” Taking a baby aspirin daily has been shown to reduce the risk of developing preeclampsia by about 15%.If you have risk factors for preeclampsia, your healthcare provider may recommend starting aspirin in early pregnancy (by 12 weeks gestation).
Choice A is wrong because avoiding foods that are high in sodium does not prevent preeclampsia.Sodium intake does not affect blood pressure in pregnancy.
Choice B is wrong because lying on your left side for at least 2 hours a day does not prevent preeclampsia.However, lying on your left side may help improve blood flow to your placenta and your baby.
Choice C is wrong because checking your blood pressure at home every day does not prevent preeclampsia.However, monitoring your blood pressure at home may help detect signs of preeclampsia early and alert you to seek medical attention if needed.
Correct Answer is A
Explanation
Respiratory rate 10/min.This indicatesmuscle weaknessanddifficulty breathing, which are symptoms ofmagnesium toxicity.Magnesium sulfate is a medication that can cause magnesium overdose if given in excess or if the patient has impaired kidney function.
Choice B.Urine output 40 mL/hr is wrong because this is within the normal range for urine output, which is 30 to 50 mL/hr.Urine output may decrease in severe cases of magnesium toxicity due to urine retention.
Choice C. Patellar reflex 2+ is wrong because this is a normal finding for the knee-jerk reflex.A low or absent patellar reflex may indicate magnesium toxicity, as it reflectsmuscle weaknessandnerve dysfunction.
Choice D.Serum magnesium level 4.5 mEq/L is wrong because this is within the normal range for serum magnesium, which is 1.7 to 2.3 mEq/L.Serum magnesium levels above 2.6 mEq/L can indicate hypermagnesemia or magnesium overdose.
