Correct Answer: D

Rationale: The priority assessment for a client being admitted to the surgical unit following a cholecystectomy is oxygen saturation. Monitoring oxygen saturation is crucial to ensure adequate oxygenation and ventilation, especially after surgery. Hypoxia can have serious consequences and needs to be promptly addressed. While assessing bowel sounds, surgical dressing, and temperature are important, oxygen saturation takes precedence in this situation.

Correct Answer: D

Rationale: The development of subcutaneous emphysema is a concerning finding that requires immediate intervention. Subcutaneous emphysema results from air leaking into the tissues, which can lead to respiratory compromise. It is important to address this issue promptly to prevent further complications. The other options are normal or expected findings in a chest tube drainage system. Chest tube eyelets not being visible may indicate dislodgement, continuous bubbling in the suction control chamber indicates proper functioning, and the presence of tidal fluctuation in the water seal chamber demonstrates appropriate drainage and lung re-expansion.

Correct Answer: C

Rationale: Following a total hip arthroplasty, the client should be instructed to restrict hip flexion past 90 degrees to prevent dislocation of the prosthesis. Restricting flexion past 120 degrees is excessive and could lead to complications. Therefore, the nurse should verify this prescription with the provider to ensure the client's safety and proper postoperative care.

Correct Answer: D

Rationale: Pyrazinamide can cause gastrointestinal upset and is best taken with a full glass of water to minimize irritation to the stomach lining. This instruction helps reduce the risk of adverse effects associated with pyrazinamide. Options A and C are not directly related to the medication regimen for tuberculosis. While sputum testing is important, the frequency mentioned in option B is not required every two weeks.

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.
