Certified EkG technician (CET) Practice Exam

When preparing a standard 12-lead EKG for a pregnant patient at 35 weeks of gestation, what is the best position for the patient?

1. Supine with legs straight

2. Slightly on the left side with a pillow supporting the right hip

3. Seated with an upright posture

4. Prone with a cushion

The correct answer is: Slightly on the left side with a pillow supporting the right hip

The best position for a pregnant patient at 35 weeks of gestation when preparing for a standard 12-lead EKG is to place her slightly on the left side with a pillow supporting the right hip. This positioning is beneficial because it helps to relieve pressure from the inferior vena cava (IVC), a major vein that returns blood to the heart. During pregnancy, especially in the later stages, the growing uterus can compress the IVC when a woman is lying flat on her back. This compression can reduce venous return, potentially leading to decreased blood flow, hypotension, and even dizziness. By positioning the patient on her left side, it enhances blood flow and oxygen supply to both the mother and fetus. The use of a pillow to support the right hip is particularly effective, as it helps to achieve a slight tilt, reducing pressure while promoting optimal circulation. This is crucial for ensuring that the EKG provides accurate readings without interference from positional effects associated with the weight of the uterus. Other positions, such as supine with legs straight or seated upright, do not adequately mitigate the risks associated with IVC compression. Lying prone is not appropriate for a pregnant patient, particularly in later gestation, due to both discomfort and the risk of
