Which pre-test activity is NOT required before an EGD?

The correct answer is that taking a shower is not a required pre-test activity before an esophagogastroduodenoscopy (EGD). While personal hygiene is important, it is not a mandated step in the preparation process for the procedure.

In contrast, removing dentures and eyeglasses is crucial as these items can interfere with the procedure and the equipment used during the EGD. Signing consent is a necessary legal requirement, ensuring that the patient understands the procedure and agrees to it. Being NPO (nothing by mouth) after midnight is essential to reduce the risk of aspiration during the procedure, as it minimizes the contents in the stomach. These preparations ensure patient safety and optimal conditions for the procedure's success.
