Final answer:
The nurse should monitor fetal heart rate (FHR) and uterine contractions (UCs) for a pregnant patient with systolic blood pressure exceeding 160 mm Hg.
Step-by-step explanation:
For a pregnant patient with a systolic blood pressure exceeding 160 mm Hg, the nurse should take the action of monitoring fetal heart rate (FHR) and uterine contractions (UCs). This is important because high blood pressure during pregnancy can pose risks to both the mother and the fetus. By monitoring the FHR and UCs, the nurse can assess the well-being of the fetus and detect any signs of distress or complications.
