Critical Care Nursing Questions and Answers PDF

Correct Answer: A

Rationale: The correct answer is A because palliative care indeed focuses on providing relief from pain and other symptoms, enhancing quality of life for patients with serious illnesses. This aligns with the essence of palliative care, which is to provide holistic support to improve comfort and well-being. The other choices are incorrect: B is wrong because palliative care does not aim to cure the underlying disease but rather to alleviate suffering; C is incorrect as palliative care can be initiated earlier in the disease trajectory, not just during the final days; and D is inaccurate because patients can continue receiving treatments alongside palliative care to manage symptoms and improve their quality of life.

Correct Answer: A

Rationale: The correct answer is A: Apply external cooling device. Therapeutic hypothermia is a treatment used to protect the brain after cardiac arrest by lowering the body temperature. The nurse should use external cooling devices, such as cooling blankets or ice packs, to achieve and maintain the desired temperature. This method allows for precise temperature control and monitoring. Checking mental status every 15 minutes (choice B) is not the priority as maintaining the temperature is crucial. Avoiding sedative medications (choice C) may be necessary to accurately assess the patient's neurological status. Rewarming if the temperature is <91�F (32.8�C) (choice D) is incorrect as the goal is to maintain hypothermia for a specific duration before gradual rewarming.

Correct Answer: A

Rationale: The correct answer is A: Vaccine. Smallpox is a contagious and potentially deadly disease caused by the variola virus. The smallpox vaccine is the most effective way to prevent and control the spread of smallpox. By obtaining adequate quantities of the smallpox vaccine, the ED nurse manager can protect healthcare workers and the public from contracting the virus in case of a smallpox bioterrorism event. Atropine (B) is used to treat certain types of nerve agent poisoning, not smallpox. Antibiotics (C) are ineffective against viruses like smallpox. Whole blood (D) is not specifically needed for smallpox treatment.

Correct Answer: B

Rationale: The correct answer is B because informed consent requires the patient to have knowledge and competence to make a decision. This involves understanding the risks, benefits, and alternatives of the proposed treatment. Choice A is incorrect as it pertains to a physical ability unrelated to decision-making. Choice C is incorrect as consent must be verbal or written, not just nodding. Choice D is incorrect as consent can be obtained in various ways, not specifically through reading and writing in English.

Correct Answer: C

Rationale: The correct answer is C: True collaboration. In this scenario, the physician consults with the nurse to understand the situation and collaborates on the best course of action for the patient's care. This demonstrates effective teamwork, communication, and mutual respect between healthcare professionals, which are key components of a healthy work environment. Choice A (Skilled communication) is not the best answer because while communication between the physician and nurse is important, the focus in this scenario is more on collaboration and teamwork. Choice B (Appropriate staffing) is not the best answer as the scenario does not specifically address staffing levels but rather the interaction and collaboration between the physician and nurse. Choice D (Recognizing signs of imminent stroke and paging the physician) is incorrect as it is unrelated to the scenario described, which is about the physician and nurse collaborating on patient care.
