Correct Answer: D

Rationale: Correct Answer: D - Give acetaminophen (Tylenol) 650 mg per nasogastric tube. Rationale: LPNs/LVNs are trained to administer medications, including oral and nasogastric routes. Giving acetaminophen via nasogastric tube is within their scope of practice. LPNs/LVNs should have the knowledge and skills to safely administer this medication as part of the hypothermia protocol. Summary of other choices: A: Continuously monitor heart rhythm - This requires specialized training and skills typically within the scope of registered nurses or cardiac monitoring technicians. B: Check neurologic status every 2 hours - Assessing neurologic status requires critical thinking and clinical judgment, which are typically responsibilities of registered nurses. C: Place cooling blankets above and below the patient - Positioning and managing cooling devices may require specific training and should be done under the supervision of a registered nurse.

Correct Answer: D

Rationale: The correct answer is D: Work of breathing. Work of breathing refers to the amount of effort required to maintain a specific level of ventilation. This includes the energy needed for inhalation and exhalation. Compliance (A) refers to the ease with which the lungs expand, resistance (B) is the opposition to airflow in the airways, and tidal volume (C) is the amount of air moved in and out of the lungs during normal breathing. Work of breathing encompasses the overall energy expenditure involved in the breathing process, making it the most appropriate term in this context.

Correct Answer: C

Rationale: The correct answer is C: Anxiety related to lack of knowledge about normal grieving. This is because the patient is expressing uncertainty and seeking validation for their feelings, indicating a lack of understanding about the grieving process. Choice A is incorrect as hopelessness typically involves feelings of despair and loss of motivation, which are not explicitly stated by the patient. Choice B is incorrect as complicated grieving involves specific unresolved issues related to the loss, which the patient did not mention. Choice D is incorrect as chronic sorrow is typically associated with ongoing feelings of sadness and longing, which are not explicitly expressed by the patient.

Correct Answer: B

Rationale: The correct answer is B: Dimming lights during the night. This intervention helps reduce stress by creating a more calming environment, promoting rest and sleep. Constant observation (choice A) may increase stress due to lack of privacy. Frequent group rounds (choice C) may disrupt rest. Use of tile floors (choice D) is unrelated to addressing noise and light stress.

Correct Answer: B

Rationale: Step-by-step rationale for why choice B is correct: 1. Midazolam is a benzodiazepine used for sedation and anxiolysis. 2. It acts quickly and has a short duration of action, suitable for acute agitation. 3. Lorazepam (also a benzodiazepine) is in the same drug class, ensuring compatibility. 4. Lorazepam is specifically ordered for this patient, indicating its appropriateness. 5. Administering midazolam addresses the patient's agitation efficiently and safely. Summary of why other choices are incorrect: A: Fentanyl is an opioid analgesic, not ideal for managing agitation. C: Increasing morphine infusion can exacerbate sedation or respiratory depression. D: Paralytic agents are used for neuromuscular blockade, not agitation control.
