Answer to Question 1

A
Feedback:
Ephedrine stimulates the release of norepinephrine from nerve endings and acts directly on adrenergic receptor sites. Therefore, the other options are incorrect.

Answer to Question 2

A
Feedback:
Hydroxyzine is used for nausea and vomiting before or after obstetric delivery or surgery. It is rapidly absorbed, metabolized in the liver, and excreted in urine. It has not been associated with fetal problems during pregnancy and is not thought to enter breast milk; however, as with all drugs, caution should be used during pregnancy and lactation. Tigan, Marinol, and Cesamet are not used for obstetric/gynecology patients.
