Correct Answer: A

Rationale: The correct answer is to suction the tracheostomy to maintain a patent airway. After a tracheostomy, the priority intervention is to ensure a clear airway to prevent respiratory distress. Administering pain medication, changing the tracheostomy dressing, and monitoring oxygen saturation are important but are secondary to maintaining a patent airway in a patient who has just undergone a tracheostomy.

Correct Answer: B

Rationale: The correct action for the nurse to take when witnessing unsafe medication administration practices, such as not using alcohol swabs, is to report the behavior to the nurse manager immediately. Patient safety is the top priority, and any actions that compromise it must be addressed promptly. Ignoring the situation (Choice A) is not appropriate as it puts patients at risk. Asking the colleague to be more careful (Choice C) may not be effective in ensuring immediate correction of the unsafe practice. Reporting the issue after speaking to other colleagues (Choice D) delays necessary action and may compromise patient safety further.

Correct Answer: A

Rationale: The correct answer is to check the ventilator tubing for disconnection first when a patient on mechanical ventilation experiences a sudden drop in oxygen saturation. This is crucial because equipment malfunction, such as tubing disconnection, can lead to decreased oxygen delivery, resulting in a drop in oxygen saturation. Checking the tubing ensures that the ventilation system is functioning properly and that the patient is receiving the necessary oxygen. Option B is incorrect because increasing oxygen flow without checking for equipment issues may not address the root cause of the drop in saturation. Option C is not the priority in this situation as the immediate focus should be on assessing and ensuring the functioning of the ventilation equipment. Option D delays addressing the potential equipment malfunction, which could worsen the patient's condition if not promptly resolved.

Correct Answer: B

Rationale: The correct answer is B: Back. Back injuries are most common during lifting and bending tasks, especially in an orthopedic unit. When lifting or repositioning patients, nurses must prioritize proper body mechanics to prevent strain on the back. Choices A, C, and D are less likely to occur as frequently as back injuries in this scenario because of the nature of the tasks involved in orthopedic patient care.

Correct Answer: D

Rationale: The correct action for the nurse is to place a surgical mask on the client for transport and for contact with other individuals when a patient under airborne precautions requires movement. This helps prevent the spread of infectious agents. Planning to have the nuclear scan at the bedside (Choice A) may not be feasible or appropriate. Calling the nuclear medicine department to delay the test (Choice B) may inconvenience the client and disrupt the scheduled procedure. Asking technicians in the nuclear scan department to wear masks (Choice C) does not provide adequate protection for others who may come into contact with the client outside the department.
