A nurse is teaching a client who is at risk for developing preeclampsia.

Which of the following statements by the client indicates an understanding of the teaching?

The correct answer is choices B, C, D, and E.These are all risk factors for pre-eclampsia according to various sources.

Choice A is wrong because age over 35 years is not a risk factor for pre-eclampsia by itself, although it may be associated with other conditions that increase the risk, such as chronic hypertension or diabetes.

Pre-eclampsia is a complication of pregnancy that involves high blood pressure, protein in the urine, and organ damage.It can affect both the mother and the fetus and can lead to serious complications such as eclampsia (seizures), placental abruption, and stillbirth.It is more common in first pregnancies, especially with a new partner, because of the immune response to the foreign fetal antigens.Obesity, diabetes mellitus, and multiple gestation are also risk factors because they increase the metabolic and vascular demands on the placenta and the mother.

Normal ranges for blood pressure and proteinuria in pregnancy are:

• Blood pressure: less than 140/90 mmHg

• Proteinuria: less than 300 mg/24 hours or less than 30 mg/dL on a random urine sample

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.
