Correct Answer: C

Rationale: The correct answer is C: Listen to the patient’s breath sounds. Moving from 22 cm to 25 cm may indicate ET tube migration. Checking breath sounds can confirm proper tube placement. A may not address the underlying issue. B could worsen the situation if the tube is misplaced. D is not urgent compared to assessing airway integrity.

Correct Answer: D

Rationale: The correct answer is D because a patient with a history of fluid overload due to heart failure is at the greatest risk of developing acute kidney injury. Heart failure can lead to decreased kidney perfusion causing acute kidney injury. In this scenario, the patient's fluid overload exacerbates the situation, further compromising kidney function. Choice A is incorrect as aminoglycosides can cause kidney injury but the duration of 6 days is less concerning compared to chronic fluid overload from heart failure in choice D. Choice B is incorrect because controlled hypertension does not directly increase the risk of acute kidney injury. Choice C is incorrect as the patient being discharged 2 weeks earlier after aminoglycoside therapy does not necessarily indicate a higher risk compared to chronic fluid overload.

Correct Answer: D

Rationale: The correct answer is D: The sister needs to maintain her own health during this time. It is essential for the sister to take care of her own health and well-being to be able to provide the best support to the patient. Continuous stress and lack of rest can negatively impact her ability to support the patient effectively. Encouraging her to rest will ensure she remains physically and mentally well to continue supporting the patient in the long run. Incorrect Choices: A: The sister is in the way of the health care providers - This is incorrect as the primary concern is the well-being of the sister and her ability to provide support. B: The patient may become annoyed by her continual presence - This is not the main reason for suggesting the sister to rest, as the focus is on her own health. C: The patient will recover more easily in peace and quiet - While peace and quiet can be beneficial for the patient, the main focus here is on the sister's well-being.

Correct Answer: A

Rationale: The correct answer is A because PE should be suspected in patients with unexplained cardiorespiratory complaints and risk factors for VTE. This is important because PE can present with nonspecific symptoms, making it crucial to consider it in the differential diagnosis. Explanation: 1. PE can present with various symptoms, including dyspnea, chest pain, and hemoptysis, but these are not present in all patients. 2. Bradycardia and hyperventilation are not classic symptoms of PE, as it can present with tachycardia and other respiratory findings. 3. Critically ill patients are actually at higher risk for VTE and PE, so prophylaxis is typically recommended. In summary, choice A is correct because it emphasizes the importance of considering PE in patients with cardiorespiratory complaints and risk factors for VTE, while the other choices contain inaccuracies or incomplete information.

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.
