A nurse is teaching a client who is preoperative for a sigmoid colostomy. Which of the following statements should the nurse include?

A. The nurse coats the indwelling urinary catheter with lubricant. This is correct procedure and requires no intervention. Lubricating the catheter reduces friction and discomfort during insertion.

B. The nurse applies the sterile drape prior to inserting the urinary catheter. This is correct procedure and requires no intervention. The sterile drape maintains a sterile field.

C. The nurse separates the client's labia with her dominant hand. The nurse should separate the client's labia with her non-dominant hand, which then remains in place as a "dirty" hand. The dominant hand, which remains sterile, is used to insert the catheter.

D. The nurse provides perineal care prior to inserting the urinary catheter. This is correct procedure and requires no intervention. Perineal care reduces the risk of introducing bacteria into the urinary tract.

A. "Small electrodes are placed on my scalp." This statement describes an EEG, not the Rinne test. The Rinne test involves a tuning fork, not electrodes. This statement is incorrect.

B. "I will wear earphones during this test." This statement describes an audiometry test, not the Rinne test. The Rinne test uses a tuning fork, not earphones. This statement is incorrect.

C. "A tuning fork is placed on my head." The Rinne test is a hearing test that involves placing a vibrating tuning fork on the mastoid process behind the ear and then comparing the sound conducted through bone to the sound conducted through air.

D. "A small probe is placed inside my ear." This statement describes tympanometry or other tests that involve probes in the ear, not the Rinne test. The Rinne test uses a tuning fork placed on the mastoid bone and near the ear canal. This statement is incorrect.
