As relates to the use of tocolytic therapy to suppress uterine activity, nurses should be aware that:
a. The drugs can be given efficaciously up to the designated beginning of term at 37 weeks.
b. There are no important maternal (as opposed to fetal) contraindications.
c. Its most important function is to afford the opportunity to administer antenatal glucocorticoids.
d. If the client develops pulmonary edema while receiving tocolytics, intravenous (IV) fluids should be given.
ANS: C
Buying time for antenatal glucocorticoids to accelerate fetal lung development may be the best reason to use tocolytics. Once the pregnancy has reached 34 weeks, the risks of tocolytic therapy outweigh the benefits. There are important maternal contraindications to tocolytic therapy. Tocolytic-induced edema can be caused by IV fluids.
