Answer to Question 1

B
Feedback
A Ritodrine is the only drug approved by the FDA for tocolysis; however, it is
rarely used because of significant side effects.
B The woman receiving decreasing doses of magnesium sulfate is often switched
to oral terbutaline to maintain tocolysis.
C Calcium gluconate reverses magnesium sulfate toxicity. The drug should be
available for complications of magnesium sulfate therapy.
D Magnesium sulfate is usually given intravenously or intramuscularly. The patient
must be hospitalized for magnesium therapy because of the serious side effects
of this drug.

administered to prevent complications from repeated transfusions.

conditions such as hepatosplenomegaly.
C Multiple transfusions result in hemosiderosis. Deferoxamine is given to chelate
iron and prevent organ damage.
