Final Exam Study Guide Respiratory Normal values pH: 7.35-7.45 PCO2: 35-45 PO2: 80 mm Hg HCO3-: 22-26 mEq/L Assessing: 1. First note pH: 2. Determine primary cause of disturbance a. Alkalo sis b. Aci dosis 3. Determine if compensation has begun Chest Tubes- 1. Procedure: a. Fill water-seal chamber with sterile water to the 2-cm level b. If suction is to be used, fill the suction control chamber with sterile water to the 20-cm level, or as ordered by the health care provider c. Encourage the client to change position frequently d. The drainage system must be maintained below the level of insertion e. Chest tubes are clamped only momentarily to check for air leaks and to change the drainage apparatus f.

If the tube becomes disconnected from the drainage system, cut the contaminated tip off the tubing, insert a sterile connector, reattach to the drainage system; or immerse the end of the chest tube in 2 cm of sterile water until the system can be reestablished Cystic Fibrosis-Hereditary dysfunction of exocrine glands, causing production of abnormally thick mucus secretions
