What should be monitored due to maternal hypoxemia?

Monitoring fetal heart rate is crucial in the context of maternal hypoxemia because hypoxemia can lead to decreased oxygen levels in the blood, which can adversely affect the developing fetus. When a mother experiences low oxygen levels, the fetus could also be deprived of adequate oxygen supply, leading to potential complications such as fetal distress or impaired growth.

Tracking fetal heart rate helps assess how well the fetus is tolerating the maternal condition. A normal fetal heart rate can indicate that the fetus is coping well despite maternal hypoxemia, while an abnormal heart rate could signal distress, prompting timely interventions. This monitoring is essential for ensuring both maternal and fetal well-being during critical situations.

The other options, while important aspects of maternal care, do not directly relate to the immediate consequences of maternal hypoxemia on the fetus.
