Basic Life Support (BLS) Practice Exam

What should providers do when performing CPR on a pregnant patient?

1. Discontinue CPR if ROSC is achieved

2. Perform CPR and left uterine displacement

3. Use only high-quality chest compressions

4. Administer supplemental oxygen

The correct answer is: Perform CPR and left uterine displacement

When providing CPR on a pregnant patient, it is important to perform high-quality chest compressions while also implementing left uterine displacement. This positioning helps to alleviate pressure from the inferior vena cava, thereby improving blood flow to the heart and brain. The baby’s weight can compress major blood vessels, particularly in later stages of pregnancy, which can diminish cardiac output and lower the effectiveness of CPR. By shifting the uterus to the left, the provider helps optimize circulation, which is crucial in a cardiac arrest situation. While high-quality chest compressions are undoubtedly vital to successful resuscitation efforts, the unique physiological changes that occur during pregnancy make left uterine displacement a necessary adjunct to standard CPR procedures. Using only high-quality compressions or administering supplemental oxygen, though important in different contexts, neglects the specific adjustments needed for pregnant patients. Additionally, once return of spontaneous circulation (ROSC) occurs, it is crucial to maintain support until the patient is stabilized, rather than discontinuing treatment prematurely. It is this combination of actions — effective compressions and proper positioning — that enhances the chances of a favorable outcome for both the mother and baby.
