Final answer:
The nurse should anticipate providing intravenous fluids and inserting a nasogastric tube for a patient with a suspected perforated ulcer.
Step-by-step explanation:
In the case of a patient with suspected perforated ulcer, the nurse should anticipate providing intravenous (IV) fluids and inserting a nasogastric (NG) tube (option A).
Patients with a perforated ulcer require immediate medical attention, as this condition can lead to peritonitis, which is a serious inflammation of the abdomen. Intravenous fluids are needed to correct any fluid imbalances and maintain hydration. Additionally, a nasogastric tube can be inserted to help decompress the stomach and relieve pressure on the abdomen.
Other options mentioned are not appropriate for the initial management of a perforated ulcer. Administering oral bicarbonate and testing the patient's gastric pH level (option B) is not effective in the acute emergency setting. Performing a fecal occult blood test and administering IV calcium gluconate (option C) is not relevant to the management of a perforated ulcer. Starting parenteral nutrition and placing the patient in a high-Fowler's position (option D) is not indicated and may delay necessary surgical intervention.
