Final answer:
The nurse would select a Salem sump tube for continuous suction through nasogastric insertion, as it is specifically designed with dual lumens for suction and venting, preventing damage to the stomach lining.
Step-by-step explanation:
The nurse is preparing to insert a nasogastric (NG) tube to enable continuous suction for a client. To select the appropriate tube, we need to consider the different types of tubes available and their uses. The Levin tube is a single lumen tube primarily used for gastric decompression or enteral feeding. The Dobhoff tube is a softer, smaller diameter tube used primarily for enteral feeding. The Salem sump tube, on the other hand, is a dual lumen tube with one lumen for suction and the other for venting; this is ideal for continuous suction as it helps prevent the suction from damaging the stomach lining. A Gastrostomy tube, or G-tube, is inserted directly into the stomach through the abdominal wall and is not meant for nasogastric insertion.
Therefore, for the purpose of continuous suction, the nurse would select the Salem sump tube, as it is specifically designed to handle this task efficiently and safely.
