Final answer:
The correct item for a nurse to obtain for a Salem sump tube prescribed by a health care provider is a tube with a large lumen and an air vent . So, correct option is (3).
Step-by-step explanation:
When a health care provider prescribes a Salem sump tube for gastrointestinal intubation, the nurse should obtain a tube with a large lumen and an air vent from the supply room. This type of tube is designed to provide dual functionality; it not only drains gastric contents to provide relief or for diagnostic purposes but also has an air vent known as a "sump" to prevent gastric mucosa from being drawn into the drainage holes. This makes option 3, A tube with a large lumen and an air vent, the correct choice.
The Salem sump tube’s design includes a smaller lumen that acts as an air vent, allowing atmospheric air to enter the stomach, equalizing the pressure and reducing the risk of mucosal suction when negative pressure is applied through the larger lumen.
The nurse should obtain a tube with a large lumen and an air vent from the supply room. This is because a Salem sump tube is used for gastrointestinal intubation and requires a tube with a large lumen to allow for the drainage of gastric contents. Additionally, the air vent allows for the release of excess air that may accumulate in the stomach during intubation.
The other options, such as the Dobbhoff weighted tube, which is a smaller, more flexible tube used primarily for enteral feeding, or the Sengstaken-Blakemore tube, which is used to control esophageal bleeding, are not suitable substitutes for a Salem sump tube.
