Answer :
Final answer:
The correct option is A. The nurse should select low continuous suction when caring for a patient with a non-vented nasogastric tube.
Explanation:
When caring for a patient with a non-vented nasogastric tube, the nurse should select low continuous suction (option a). This setting allows for a continuous suctioning effect to prevent the build-up of gastric contents in the stomach. High suction settings can be harmful and may lead to tissue damage. Intermittent suction is not recommended because it may cause gastric contents to stagnate in the stomach.
This type of suction setting is typically employed in care practice, as it poses less risk of mucosal damage to the patient's stomach lining, thereby minimizing the risks associated with higher or intermittent suctions. Risks that are typically associated with high or intermittent suctions, such as gastric mucosal ischemia or necrosis, are significantly reduced with a low continuous suction setting.
