Correct Answer: B

Rationale: The correct answer is B: Administer a prescribed PRN opioid analgesic. This is the priority intervention because severe breakthrough pain requires immediate relief, and opioids are the most effective for managing severe pain in terminally ill patients. Warm compresses (A) may provide some comfort but do not address the underlying pain. Reassessing pain after 2 hours (C) delays necessary relief. Distraction techniques (D) are not appropriate for severe breakthrough pain as they do not directly address the pain itself. Administering the prescribed opioid analgesic promptly is crucial for providing timely and effective pain management in this situation.

Correct Answer: D

Rationale: The correct answer is D because initiating the alcohol withdrawal protocol shows an understanding of managing a patient at risk for alcohol withdrawal syndrome. This protocol involves carefully monitoring the patient's symptoms, providing appropriate medications, and ensuring a safe environment. Option A is incorrect as it downplays the seriousness of alcohol withdrawal. Option B is incorrect as there are assessment tools available for identifying alcohol withdrawal. Option C is incorrect as pain management should be tailored to the individual's needs, not necessarily lessened due to alcohol withdrawal risk.

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: 46.8; meets criteria for ARDS. The PaO /FiO ratio is calculated by dividing the arterial oxygen partial pressure (PaO) by the fraction of inspired oxygen (FiO). In this case, PaO is 78 mm Hg and FiO is 0.6 (60%). Therefore, the calculation would be 78/0.6 = 130. This value is less than 300, which is indicative of ARDS according to the Berlin criteria. Choices B and C are incorrect as they do not align with the criteria for ARDS. Choice D is incorrect because the data provided is sufficient to compute the ratio.

Correct Answer: A

Rationale: The correct answer is A because it demonstrates effective handoff communication by involving key stakeholders (nephrology consultant physician), requesting specific patient updates, and collaborating on patient care tasks (placing a central line). This scenario promotes continuity of care and ensures important information is shared. Explanation for why other choices are incorrect: B: High noise level disrupts communication and can lead to errors or omissions in handoff information. C: While using a standardized checklist can be beneficial, it alone does not guarantee effective communication if not utilized properly or if key information is missed. D: Conducting reports at the patient's bedside is beneficial for patient involvement but may not address the need for involving relevant healthcare providers like the consultant physician in the handoff process.
