A.

Serum magnesium level of 8 mg/dL

B.

Serum calcium level of 7 mg/dL

C.

Serum creatinine level of 1.2 mg/dL

D.

Serum potassium level of 3.8 mEq/L

E.

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.

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.

Correct Answer is D

Explanation

“I will resume my normal activities as soon as possible.” This statement indicates a need for further teaching because a woman who had severe pre-eclampsia should rest more often and avoid strenuous activities until her blood pressure is normal and stable.She should also follow up with her doctor regularly and monitor her blood pressure at home.

Choice A is wrong because it is important to monitor blood pressure at home for a few weeks after having pre-eclampsia.

This can help detect any signs of worsening hypertension or organ damage.

Choice B is wrong because it is advisable to call the doctor if there are any headaches or vision changes, as these could be signs of brain injury or eclampsia.

Eclampsia is a serious complication of pre-eclampsia that causes seizures.

Choice C is wrong because some over-the-counter pain medications, such as ibuprofen, can increase blood pressure and should be avoided by women with pre-eclampsia.However, acetaminophen (Tylenol) is usually safe to take for mild pain relief.

Normal ranges for blood pressure during pregnancy are less than 140/90 mmHg.Normal ranges for protein in urine during pregnancy are less than 300 mg in 24 hours.
