The nurse is caring for a client who is scheduled for a transesophageal echocardiogram. What nursing intervention is a priority after the procedure?

Choice A rationale Transesophageal echocardiography involves the insertion of an ultrasound probe through the esophagus rather than an arterial or venous puncture in the extremities. Monitoring a puncture site and assessing distal pulses are interventions typically reserved for cardiac catheterization or arterial procedures. Because this procedure is endoscopic in nature, there is no peripheral vascular access site created that would require frequent neurovascular checks or monitoring for hematoma formation in the limbs. Choice B rationale Assessing for hematuria or melena is not a priority following an esophageal procedure. While internal trauma is a rare risk, these symptoms are more indicative of systemic bleeding or gastrointestinal issues unrelated to the ultrasound probe. The nurse should focus on local complications such as esophageal perforation or aspiration rather than systemic hemorrhage in the urine or stool. Standard laboratory values for hemoglobin are 12 to 16 g/dL for women and 14 to 18 g/dL for men. Choice C rationale Positioning the client on the right side to watch for site bleeding is an intervention specific to a liver biopsy, where the weight of the body helps provide pressure to the puncture site. For a client post transesophageal echocardiography, the primary concern is the return of protective airway reflexes. Positioning should facilitate drainage of secretions and prevent aspiration rather than focusing on a non-existent external surgical site or localized pressure on the liver. Choice D rationale During this procedure, the throat is numbed with a topical anesthetic to facilitate probe insertion. This suppresses the gag reflex, significantly increasing the risk of aspiration if oral intake occurs too soon. Keeping the head of the bed at 45 degrees promotes lung expansion and prevents secretions from entering the trachea. The nurse must verify the return of the gag reflex by using a tongue blade before allowing any fluids or food.
