EXAM 3 LEVEL 3 NURSING SCF ACTUAL 2025/2026 QUESTIONS AND 100% CORRECT ANSWERS Chest Tube Indications - Answer -Closed chest drainage system. Inserted in the pleural space to drain air, fluid or blood. Pressure in thoracic cavity is lower/negative than atmospheric pressure. A hole in the chest, air will flow in towards the negative pressure. Commonly used in trauma or thoracic, CABAG surgery-when the thoracic cavity we lose negative pressure. Rib can punctures a lung, cancer, can happen spontaneously, How a chest drainage system works - Answer --Inserted in between the visceral & parietal pleura "pleural space" or Mediastinal space, Restores negative pressure so the lung can expand properly -Expiratory positive pressure from the patient helps push air and fluid out of the chest (cough, Valsalva) -Gravity helps fluid drainage as long as the chest drainage system is below the level of the chest -Suction can improve the speed at which air and fluid are pulled from the chest Pneumothorax (PTX) - Answer -excess air in the chest cavity, it takes up space so the lungs cannot expand Hemothorax - Answer -blood in the chest cavity (which takes up space so lung cannot expand causing a collapsed lung Empyema - Answer -pus in a body cavity, especially the pleural cavity Collection Chamber - Answer -Closed Chest Drainage: Fluid drains into the chest tube thru a connecting tube & then into a collection chamber Need assistance on Online classes, Exams & Assignments?

Tidaling - Answer -Normal Finding: Fluctuations in the water seal chamber fluid level that correspond w/respirations, only with tall water column, adjusts w/Patient's respirations, Stops if lung is fully re-expanded or system obstructed. Note: w/chest tube, water should rise with inspiration & fall with expiration but visa versa if on a ventilator Bubbling In Water Seal Chamber - Answer -In the bottom of the water seal chamber indicates an air leak (caused most often by poor tubing connections, Air leaks: could be patient chest tube insertion site, loose connection, Check if patient is in distress Control Regulator - Answer -water filled or dry suction removes chest drainage & maintains flow Pleural Space - Answer -Normally has about 20 mL of fluid for lubrication, & -20 cm of negative pressure Traditional Water Seal a/k/a Wet Suction - Answer -It has 3 chambers; a collection chamber, water seal chamber, & a wet suction control chamber, requires sterile fluid instilled into water seal & suction chambers. It has positive & negative pressure release valves, you will have intermittent bubbling this indicates proper functioning. Additional suctioning can be added by connecting to a suction source Dry Suction Water Seal - Answer -Common in hospitals, 3 chambers, a collection chamber, water seal chamber (middle chamber) & suction regulator dial. Requires sterile fluid instilled in water seal chamber at 2-cm level, no fluid filled suction chamber. Suction pressure is set w/an orange regulator dial. Has Positive & Negative pressure release valves, Has an indicator to signify that the suction pressure is adequate, Quieter than traditional water seal systems Dry Suction Also referred to as a one-way valve system Need assistance on Online classes, Exams & Assignments?
