Answers and Rationale
- Rifampin may be tuberculocidal or tuberculostatic against the Mycobacterium tuberculosis bacteria. It's usually given with other antitubercular drugs to prevent or delay resistance. The drug impairs ribonucleic acid synthesis of bacteria. It acts against, active not resting, bacteria.
- Tidal volume is the amount of air inspired and expired with each breath. Residual volume is the amount of air remaining in the lungs after forcibly exhaling. Vital capacity is the maximum amount of air that can be moved out of the lungs after maximal inspiration and expiration. Dead-space volume is the amount of air remaining in the upper airways that never reaches the alveoli. In pathologic conditions, dead space may also exist in the lower airways.
- To lessen the spread of TB, everyone who had contact with the client must undergo a chest X-ray and TB test skin. Testing will help determine if the client infected anyone else. The remaining options are important areas to address when educating high-risk populations about TB is prior to its development.
- When caring for a client who's recovering from a thoracotomy, the nurse should encourage coughing and deep breathing to prevent pneumonia. Fluctuations in the water-seal chamber are normal. Clamping the chest tube could cause a tension pneumothorax. Chest tube milking is controversial and should be done only to remove blood clots that obstruct the flow of drainage.
- A client who is free from infection will most likely have decreased oxygen requirements. A client with infection will display increased sputum production, fever, shortness of breath, decreased activity tolerance, and increased oxygen requirements.
