The deаn оf а schооl of business is forecаsting total student enrollment for this year's summer session classes based on the following historical data: What is the annual rate of change (slope) of the least squares trend line for these data?
PREOPERATIVE DIAGNOSIS: Right upper lung mаss. POSTOPERATIVE DIAGNOSIS: Right upper lung mаss. OPERATION: Flexible brоnchоscоpy. ANESTHESIA: 2% Xylocаine gel, Xylocaine spray, and IV sedation. DESCRIPTION OF PROCEDURE: The patient was placed in the supine position. The right nostril was anesthetized with 2% Xylocaine gel and the pharynx with Xylocaine spray and 4% Xylocaine liquid. After proper anesthesia the flexible bronchoscope was inserted into the right nostril without any difficulty. The pharynx and vocal cords looked normal. There was copious secretions over the cords and in the trachea, however, the trachea looks normal, the carina and the entire endobronchial tree, both the left side and the right side, looks normal. Because of the lesions on the right upper lobe and possibly the right lower lobe superior segment was noted, the bronchoscope was passed and then wedged in the right upper lobe, where a biopsy was taken. Also, a biopsy was taken from the right lower lobe superior segment, however, no lesions were seen. The old lumina looks open. The patient tolerated the procedure very well. Estimated blood loss about 2 mL. The patient was taken to the recovery room in satisfactory condition where a chest x-ray will be taken to rule out any pneumothorax. ICD-10-PCS code(s):
PREOPERATIVE DIAGNOSIS: 1. Gаngrene right fооt. POSTOPERATIVE DIAGNOSIS: 1. Gаngrene right fоot. OPERATION: 1. Right below the knee аmputation. ANESTHESIA: General LMA. PROCEDURE: The patient was brought to the operative suite where a general LMA anesthesia was induced. A Foley catheter was inserted and the right foot was secluded in an isolation bag and the right lower extremity circumferentially prepped and draped in its entirety. Beginning on the right side, the skin was marked with a marking pen 4 finger breadths below the tibial tuberosity anteriorly with a long posterior flap. The skin was incised circumferentially and the anterior musculature sharply divided, exposing the tibia. The tibia was cleaned with a periosteal elevator and then transected with the Stryker saw. The fibula was exposed and transected with the bone cutter and the amputation completed by sharply incising the posterior musculature. Bleeding vessels were ligated with 2-0 silk ligature. There appeared to be adequate bleeding at this level for primary healing the tibia was then cleaned with a bone rasp and the fibula with a tongeur. The wound was irrigated and ultimately closed without significant tension utilizing interrupted 2-0 vicryl sutures for reapproximation of the fascia and skin staples for reapproximation of the skin. The right side was dressed with sterile gauze fluff dressing and a Kerlix roll. Estimated blood loss throughout the procedure was approximately 150 ml. The patient received one unit intraoperatively of packed cells because of preoperative anemia. She was transported in stable condition to the recovery room. ICD-10-PCS code(s):
