Correct Answer: D

Rationale: Repositioning the endotracheal tube to the opposite side of the mouth daily is not a standard practice and can increase the risk of complications, such as accidental extubation or damage to the airway. The endotracheal tube should remain in the initial correct position to ensure proper ventilation and prevent harm to the client. Elevating the head of the bed, verifying ventilator settings, and administering pantoprazole as prescribed are all appropriate interventions to prevent complications in a client receiving positive-pressure mechanical ventilation.

Correct Answer: A

Rationale: In the case of anthrax exposure, the recommended antibiotic for prophylaxis and treatment is Ciprofloxacin. Ciprofloxacin is effective against the anthrax bacterium, Bacillus anthracis. Fluconazole is an antifungal medication, Tobramycin is an aminoglycoside antibiotic used for bacterial infections, and Vancomycin is a glycopeptide antibiotic primarily used for Gram-positive bacterial infections. Therefore, the correct choice is Ciprofloxacin.

Correct Answer: C

Rationale: Ventilator-associated pneumonia (VAP) is a common complication in clients receiving mechanical ventilation. Oral hygiene is crucial in reducing the risk of VAP. Brushing the client's teeth with a suction toothbrush every 12 hours helps prevent bacterial colonization in the oral cavity, which can be aspirated into the lungs. Positioning the head of the bed flat can increase the risk of aspiration. Turning the client every 4 hours is important for preventing pressure ulcers but not directly related to reducing VAP. Providing humidity in the ventilator tubing helps maintain airway moisture but does not directly address the risk of VAP.

Correct Answer: B

Rationale: It is crucial for clients using inhaled corticosteroids like fluticasone to inspect their mouths daily for signs of oral thrush, a common side effect. Checking the mouth can help identify lesions early, allowing for timely intervention to prevent worsening of the condition. Monitoring heart rate is not specifically required for this medication. Fluticasone is a maintenance medication used to manage COPD, not to relieve acute attacks. Skipping doses, especially in the morning, can lead to inadequate control of COPD symptoms.

Correct Answer: A

Rationale: In a client with a three-chamber closed chest tube system, a rise in the water seal chamber with client inspiration is an expected finding. The nurse should continue to monitor the client as this indicates that the system is functioning correctly. There is no need to notify the healthcare provider, reposition the client, or clamp the chest tube as these actions are not indicated in response to a rise in the water seal chamber.
