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.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
