Correct Answer: A

Rationale: The correct answer is A: Drain condensate from the ventilator tubing away from the patient. This is crucial to prevent ventilator-associated pneumonia as stagnant condensate can harbor harmful bacteria. By draining it away from the patient, the risk of bacterial growth and subsequent aspiration is minimized. Elevating the head of the bed (choice B) helps prevent aspiration but is not specific to preventing ventilator-associated pneumonia. Instilling normal saline during suctioning (choice C) can increase the risk of infection. Performing regular oral care with chlorhexidine (choice D) is important for oral hygiene but not directly related to preventing ventilator-associated pneumonia.

Correct Answer: C

Rationale: The correct answer is C because palliative care is not just for the dying but also for those with serious illnesses. A: Correct - basic nursing care is essential in palliative care. B: Correct - common symptoms in palliative care include nausea, agitation, and sleep disturbance. D: Correct - palliative care aims to relieve symptoms and improve quality of life. Choice C is incorrect as it wrongly implies palliative care is only for the dying, which is a misconception.

Correct Answer: B

Rationale: The correct answer is B: Hypoxemia and compensated respiratory acidosis. The patient's pH is within normal range (7.35), indicating compensation. The elevated PaCO2 (55 mm Hg) indicates respiratory acidosis due to inadequate ventilation, likely from COPD. The low PaO2 (65 mm Hg) indicates hypoxemia, common in pneumonia. The normal bicarbonate level (30 mEq/L) suggests metabolic compensation for respiratory acidosis. Choice A is incorrect as there is no metabolic alkalosis present. Choice C is incorrect as the patient has hypoxemia. Choice D is incorrect as the patient is showing compensated respiratory acidosis, not uncompensated.

Correct Answer: C

Rationale: Step-by-step rationale for why choice C is correct: 1. Going to the patient’s bedside is the priority as it allows the nurse to assess the patient's condition directly. 2. By being at the bedside, the nurse can quickly evaluate the patient's breathing, vital signs, and other indicators for immediate action. 3. Direct assessment enables timely intervention and avoids delays in addressing potential life-threatening situations. 4. Checking for possible causes of the alarm and reconnection to the ventilator can follow, but assessing the patient's immediate needs takes precedence. In summary, choice C is correct because direct patient assessment is the fundamental step in responding to a ventilator alarm to ensure patient safety and timely intervention. Choices A, B, and D are incorrect as they focus on troubleshooting and technical aspects before directly assessing the patient's condition.

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.
