The nurse on the antenatal unit is planning care for four clients. The nurse should assess which of the following clients first?

1. A 29-year-old G3 P2 carrying twins, being treated for preterm labor at 29 weeks' gestation. She is receiving magnesium sulfate at 2 g/h. She has had no contractions for the past 2 hours and both twins appear stable, according to the nurse's shift report.

2. A 19-year-old 18 weeks' intrauterine pregnancy (IUP) who is now 12 hours post motor vehicle accident with bright red vaginal bleeding.

3. A G8 P4 Ab3 at 38 weeks' gestation hospitalized frequently during this pregnancy for placenta previa. Two days ago, she was admitted with severe bright red vaginal bleeding that has tapered off now.

4. A 9-week IUP hospitalized for hyperemesis gravidarum who has not vomited for the last 12 hours.
