A patient needs to have his gallbladder removed. The MAA should schedule the patient for which of the following procedures?

When a patient requires the removal of the gallbladder, the appropriate procedure to schedule is cholecystectomy. This surgical operation specifically targets the gallbladder, which is responsible for storing bile produced by the liver. In cases of gallstones, inflammation, or other gallbladder-related issues, a cholecystectomy is commonly performed to alleviate symptoms and prevent complications.

Understanding the context of other procedures can illustrate why cholecystectomy is the correct choice. An appendectomy involves the removal of the appendix and is unrelated to gallbladder issues. Adenectomy pertains to the removal of a gland and does not apply to the gallbladder. Colectomy refers to the surgical removal of part or all of the colon, which also does not connect to gallbladder concerns. Thus, in the context of gallbladder removal, cholecystectomy is the only correct procedure to schedule.
