Which procedure is contraindicated for a patient diagnosed with placenta previa?

In patients diagnosed with placenta previa, a digital exam is contraindicated primarily due to the risk of causing bleeding. Placenta previa occurs when the placenta partially or completely covers the cervix, which can lead to significant complications if any manipulation is done in that area, such as a digital examination.

Performing a digital exam could potentially disrupt the placental attachment or irritate the placenta, leading to hemorrhage. Instead, management of placenta previa typically involves monitoring and avoiding activities that could induce contractions or bleeding, making non-invasive assessments like ultrasound the preferred method of evaluation.

In contrast, ultrasound examination is a standard practice for assessing the condition of the placenta and monitoring fetal well-being. Dilation and curettage is not typically performed in cases of placenta previa as it could lead to significant bleeding; however, it is not ideal to classify it with the same level of urgency as a digital exam. A cesarean section is the recommended method of delivery if placenta previa does not resolve, as it prevents any risk associated with vaginal delivery in this circumstance.
