Which action is appropriate to prevent stimulation of the gallbladder in acute cholecystitis?

Maintaining NPO (nothing by mouth) status and using nasogastric suctioning is appropriate for preventing stimulation of the gallbladder in acute cholecystitis. In this condition, inflammation of the gallbladder typically occurs due to the presence of gallstones, and providing any oral intake or stimulating the digestive system can exacerbate symptoms and lead to further complications.

By keeping the patient NPO, the digestive system is allowed to rest, thereby minimizing the gallbladder's activity and reducing the risk of additional inflammation or pain. Nasogastric suctioning further aids in decompressing the stomach and preventing the accumulation of gastric contents, which can also stimulate the gallbladder due to the digestive processes triggered by food intake.

In contrast, a high-fat diet would stimulate gallbladder contraction. Encouraging fluid intake without medical supervision may also lead to difficulties in managing the patient's condition, especially if there is nausea or vomiting involved. Providing frequent small meals could inadvertently stimulate the gallbladder as well, further complicating the patient's acute condition. Thus, the combination of NPO status and nasogastric suction is crucial in managing acute cholecystitis.
