Correct Answer: B

Rationale: The correct answer is B: Disconnect the flush system from the arterial line catheter. This action is necessary to prevent air from entering the patient's bloodstream, which can lead to air embolism. By disconnecting the flush system, the nurse stops the flow of air and ensures patient safety. Checking the inflation volume of the pressurized bag (A) is not the immediate concern in this situation. Zero referencing the transducer system (C) is unrelated to the issue of air entering the arterial line. Reducing the number of stopcocks in the flush system tubing (D) does not address the immediate risk of air embolism.

Correct Answer: B

Rationale: The correct answer is B because withdrawal is a common psychological response in the dying process. The nurse should explain to the son that his mother's lack of response may be her way of preparing to leave life. This response validates the son's concerns while providing reassurance. Choice A is incorrect because cutting back visits may not address the underlying issue of the mother's withdrawal. Choice C is incorrect because stimulating the mother may not be beneficial or appropriate in this situation. Choice D is incorrect because not all patients experience a lack of awareness at the end of life, and assuming so may not be helpful in this context.

Correct Answer: A

Rationale: The correct answer is A because assessing the patient and family's developmental stages and needs is crucial in understanding their current situation and determining the appropriate care plan. By assessing developmental stages, the nurse can tailor interventions to meet the family's specific needs. This assessment also helps in identifying potential challenges or areas requiring support. Choice B is incorrect as it focuses solely on the physical environment and does not address the family's developmental stages and needs. Choice C is incorrect as it emphasizes identifying family members without considering the importance of understanding their developmental stages and needs in providing family-centered care. Choice D is incorrect as it concentrates on family dynamics without directly addressing the crucial aspect of assessing developmental stages and needs for effective family-centered care.

Correct Answer: C

Rationale: The correct answer is C: Suggesting that he meet with the hospital chaplain. This approach is best as it addresses the young man's emotional and spiritual needs during a difficult time. The chaplain can provide comfort, support, and guidance in coping with his girlfriend's situation. This option focuses on holistic care and acknowledges the importance of emotional well-being. A: Recommending that he go home and rest is not the best approach as it dismisses the young man's emotional distress. B: Giving him unrestricted visiting hours with the patient may not be appropriate as it can be overwhelming and may not address his emotional needs effectively. D: Recommending that he ask the doctor to evaluate the patient's pain control measures is important but does not directly address the young man's emotional needs in this situation.

Correct Answer: C

Rationale: The correct answer is C, the 86-year-old postoperative from colonic resection. This patient is at the greatest risk for delirium due to being elderly, having undergone surgery, and having a history of being from a nursing home. These factors contribute to an increased susceptibility to delirium. A: The 36-year-old with alcohol withdrawal may be at risk for delirium tremens, but the older age of the patient in choice C places them at higher risk. B: The 54-year-old with an elevated creatinine level postoperative is at risk for complications, but age and history of nursing home placement increase the risk for delirium in choice C. D: The 95-year-old with community-acquired pneumonia is at risk for delirium, but the combination of age, surgery, and nursing home history in choice C presents a greater risk.
