A nurse is providing discharge teaching to a client who is 1 day postoperative following a right modified radical mastectomy.
Which of the following instructions should the nurse include in the teaching?

Aspirate contents from the tube and verify the pH level.

• A. This is an incorrect action. Inserting air in the tube and listening for gurgling sounds in the epigastric area is not a reliable method to confirm NG tube placement, as it can produce falsepositive results due to air entering the stomach or intestines.
• B. This is a correct action. Aspirating contents from the tube and verifying the pH level is a valid method to confirm NG tube placement, as gastric contents typically have a pH of less than 5.5, while intestinal or respiratory contents have a higher pH.
• C. This is an incorrect action. Reviewing the medical record for previous x-ray verification of placement is not sufficient to confirm NG tube placement, as the tube can migrate or become dislodged after insertion. X-ray verification should be done initially and whenever there is doubt about the tube's position.
• D. This is an incorrect action. Auscultating the lungs for adventitious breath sounds is not a specific method to confirm NG tube placement, as it can indicate other conditions such as pneumonia or pulmonary edema. It can also miss signs of respiratory complications due to NG tube misplacement, such as pneumothorax or bronchial obstruction.

Choice A rationale:

Massaging the legs before applying the stockings is not advisable. Vigorous massage can dislodge clots in patients with DVT, leading to serious complications like pulmonary embolism. It is essential to handle the legs gently and follow the proper procedure for applying antiembolitic stockings.

Choice B rationale:

Folding the stockings at the top if they are too long is not recommended. Altering the stockings in this way can create uneven pressure, reducing their effectiveness in preventing DVT. It is crucial to choose the correct size of stockings to ensure proper compression and prevention of complications.

Choice C rationale:

Measuring the legs with a tape measure to determine the stocking size is the correct action. Proper sizing is essential to ensure the stockings fit the patient correctly and provide the appropriate level of compression. Ill-fitting stockings can be ineffective and may even cause harm, such as skin abrasions or impeded circulation.

Choice D rationale:

Removing the stockings every 24 hours is unnecessary unless there is a specific medical indication to do so. Continuous wear of antiembolitic stockings is generally recommended to provide consistent compression and prevent deep-vein thrombosis (DVT)
