Correct Answer: A

Rationale: The correct answer is A: Airway clearance therapies. In cystic fibrosis (CF), mucus buildup in the lungs can lead to infections and breathing difficulties. Airway clearance therapies help loosen and clear this mucus, improving lung function. Antibiotic therapy (B) is used to treat infections but is not specific to CF treatment. Nutritional support (C) is crucial in CF due to malabsorption, but it is not the primary treatment. Tracheostomy (D) is a surgical procedure to create an airway bypassing the upper respiratory tract and is not a standard treatment for CF.

Correct Answer: A

Rationale: The correct answer is A because it respects the patient's right to privacy while also acknowledging the family's presence. By asking family members if they wish to remain in the room, the nurse allows them to make an informed decision based on their comfort level. This approach fosters open communication and shows respect for the family's emotions. Choice B is incorrect because abruptly removing family members can increase their distress and feelings of powerlessness. Choice C is incorrect as it places the burden of support solely on a staff member, potentially isolating the family from the situation. Choice D is incorrect as it assumes family members should stay without considering their preferences or emotional well-being.

Correct Answer: C

Rationale: The correct answer is C: Notify the organ procurement organization (OPO). This is the best action because the OPO is responsible for coordinating organ donation and transplantation. By involving the OPO, the nurse ensures that the donation process is handled appropriately and ethically. Choice A: Arranging a multidisciplinary meeting with physicians may be necessary but should not be the first step in this situation. Choice B: Consulting the hospital’s ethics committee may be helpful, but the immediate priority is to involve the OPO to facilitate organ donation. Choice D: Obtaining family consent to withdraw life support is not the nurse’s role in this situation. The focus should be on organ donation to honor the family's wishes.

Correct Answer: C

Rationale: The correct answer is C: A woman who originally escorted the patient in. This choice is correct because she is most likely the person responsible for the patient's care and thus likely has legal authority to make medical decisions on behalf of the patient. The other choices are incorrect because simply being recognized as the patient's brother (A), being a teenage boy who approaches the nurse (B), or being a woman whom the others look at and call over (D) does not necessarily indicate that they have the legal authority to make medical decisions for the unconscious patient.

Correct Answer: D

Rationale: The correct answer is D because monitoring the surgical incision for signs of infection is essential post-VAD implantation to prevent complications. This step is crucial in early identification and treatment of any potential infection, which can lead to serious outcomes. A) Giving immunosuppressive medications is not typically required for VAD implantation, as the primary goal is to support cardiac function rather than prevent rejection. B) Preparing the patient for a permanent VAD is premature, as the goal is often to bridge to transplantation or recovery, not permanent VAD placement. C) Teaching the patient the reason for complete bed rest is not necessary for VAD implantation, as patients are typically encouraged to gradually increase activity levels under guidance.
