A pregnant female presents with sudden shortness of breath and leg swelling. What should be prioritized in her care?

In the context of a pregnant female presenting with sudden shortness of breath and leg swelling, administering oxygen is prioritized because these symptoms may indicate a significant concern such as a pulmonary embolism (PE) or other respiratory distress. Adequate oxygenation is critical, as it directly affects both the mother and the developing fetus.

Shortness of breath can lead to hypoxia, and in pregnancy, this is particularly concerning because the fetus relies on the mother's oxygen supply for development. Oxygen therapy can help alleviate hypoxic conditions by increasing the availability of oxygen in the bloodstream, which is vital for both maternal and fetal well-being.

While the other options may provide some benefit in specific situations, they do not address the immediate need to ensure adequate oxygenation. For instance, applying a compression wrap or using hot packs may aid in managing leg swelling, but these measures do not address the potential life-threatening distress indicated by shortness of breath. Elevating the legs may assist with venous return and swelling, but again, it does not directly address the urgency posed by respiratory issues. Thus, the priority must be on ensuring the patient receives oxygen to stabilize her condition.
