A nurse is collecting data from an older adult client who has cystitis. Which of the following findings should the nurse anticipate?

Choice A: This is incorrect because applying petroleum jelly to the client's nares can interfere with oxygen delivery and cause skin breakdown. The nurse should use water-soluble lubricant or saline spray to moisten the nares and prevent dryness from oxygen therapy.

Choice B: This is correct because initiating fall precautions can prevent injury and complications for the client who has aspirated pneumonia and hypoxia. The client may have altered mental status, weakness, or dizziness due to hypoxia, infection, or medications. The nurse should use bed alarms, side rails, and assistive devices as needed.

Choice C: This is incorrect because maintaining the client in a supine position can worsen hypoxia and pneumonia by decreasing lung expansion and increasing secretions. The nurse should elevate the head of the bed at least 30 degrees and encourage frequent position changes to improve ventilation and drainage.

Choice D: This is incorrect because implementing contact precautions is not indicated for the client who has aspirated pneumonia and hypoxia. Aspirated pneumonia is caused by inhalation of foreign material into the lungs, not by transmission of microorganisms from person to person. The nurse should use standard precautions and droplet precautions if the client has a cough or sputum production.

Choice A reason: Applying moist heat to the incision while in bed is not an appropriate instruction, as it can increase the risk of infection, bleeding, or swelling at the site. The nurse should instruct the client to keep the incision dry and covered with a sterile dressing.

Choice B reason: Performing range of motion by adducting the hip is not an appropriate instruction, as it can cause dislocation or damage to the prosthesis. The nurse should instruct the client to avoid crossing their legs or turning their toes inward and to use an abduction pillow or wedge between their legs.

Choice C reason: Sitting in a straight-backed chair is an appropriate instruction, as it can prevent flexion contractures and promote circulation and healing in the hip joint. The nurse should instruct the client to use a raised toilet seat and a chair with armrests and avoid sitting for longer than 45 min at a time.

Choice D reason: Cleansing the surgical incision with hydrogen peroxide is not an appropriate instruction, as it can irritate or damage the tissue and delay wound healing. The nurse should instruct the client to use mild soap and water or saline solution to clean the incision and pat it dry gently.
