Answer to Question 1

ANS: A, B, D
Steroid hormones, decreased GI motility, and increased blood volume all affect maternal drug effectiveness. Renal perfusion is increased during pregnancy. Poor sleep does not alter drug effectiveness. Rapid respiratory rate does not necessarily occur.

Answer to Question 2

ANS: D
Patients receiving magnesium sulfate can develop toxicity, evidenced by lethargy, slurred speech, and decreased muscle tone. A level greater than 10 mEq/L indicates toxicity. Patients with severe eclampsia will have marked elevation of blood pressure and seizures.
