Answer to Question 1

ANS: D
For fetal neuroprotective uses, magnesium sulfate should be given using a low-dose protocol, which is a 4-gm IV loading bolus over 20 minutes, followed by a maintenance infusion of 1 gm/hr. A high-dose protocol would have a maintenance infusion of 2 to 3 gm/hr. The nurse should question the maintenance amount. The bolus amount and rate are correct.

Answer to Question 2

ANS: C
Tocolytic agents are used to postpone premature labor and, on average, for only 48 hours. During this time, glucocorticoids are given to help the fetal lungs mature. Tocolytic agents do not suppress labor long term. They do not directly help the fetal lungs to mature; they help by allowing time for glucocorticoids to be given. They do not treat infection.
