A nurse is caring for a client who has peptic ulcer disease and is scheduled to undergo an esophagogastroduodenoscopy. Which of the following actions should the nurse take prior to the procedure?

Ensure that the client has given informed consent. Obtaining informed consent is a critical step before any medical procedure. It ensures that the client understands the nature of the procedure, its risks, benefits, and alternatives, and voluntarily consents to it. It is essential to ensure that the client has given their informed consent before proceeding with the EGD. The other options do not directly pertain to the EGD procedure: - Administering an oral contrast solution is typically not part of the preparation for an EGD. - Informing the client about the duration of the procedure is important for the client's understanding, but it is not the primary action for the nurse to take. - Ensuring that the client's bladder is full is not a standard preparation for an EGD.
