Which nursing intervention would be most appropriate for a patient with a paracentesis due to ascites?

Choice A reason: The prone position is incorrect for a paracentesis. The patient should be positioned in an upright or High-Fowler's position, usually sitting at the edge of the bed or reclining with the head of the bed elevated. This allows gravity to pull the ascitic fluid toward the lower abdominal wall for easier access. Choice B reason: Rapid removal of a large volume of ascitic fluid (large-volume paracentesis) can cause a major fluid shift from the intravascular space into the vacated peritoneal cavity. This can lead to post-paracentesis circulatory dysfunction, characterized by severe hypotension and shock. Monitoring vital signs and administering albumin or IV fluids is a critical safety intervention. Choice C reason: Immediate ambulation is contraindicated. Following a paracentesis, the patient should be monitored for several hours for signs of leakage from the puncture site, hemorrhage, or hemodynamic instability. Rapid movement could exacerbate potential orthostatic hypotension resulting from the sudden shift in intra-abdominal pressure and vascular volume. Choice D reason: Restricting oral fluid intake is not a standard requirement "during the procedure." While patients with ascites may be on long-term fluid restrictions, the primary concern during the procedure itself is the risk of vascular collapse, which is managed via intravenous volume expanders rather than restricting oral intake.
