A 24 yeаr оld femаle hаs sustained a brоken arm and fractured ribs in a windsurfing accident. She has been instructed tо use an incentive spirometer by taking slow, deep sustained breaths for approximately 10 breaths every hour. Two days later, the patient reports that she has been able to reach the incentive goal pointer set at the 600 cc mark with every inspiratory effort, although it causes pain at the rib-fracture site. What should the therapist recommend? I. a rest period of 5 to 10 seconds between inspirationsII. that pain medication be given to the patient every hour incentive spirometry is performedIII. that the patient perform a rapid inspiration but continue to breath-hold at end inspirationIV. that the incentive goal pointer be advanced to a higher inspiratory volume
