Correct Answer: B

Rationale: Step 1: Influenza can lead to pneumonia as a complication, so getting an annual flu shot can reduce the risk of pneumonia. Step 2: Providing education on the importance of prevention aligns with discharge teaching goals. Step 3: Option A is incorrect as the pneumococcal vaccine doesn't guarantee immunity from all causes of pneumonia. Step 4: Option C is incorrect as cold or drafty places do not directly cause pneumonia. Step 5: Option D is incorrect as having pneumonia once does not confer permanent immunity.

Correct Answer: B

Rationale: The correct answer is B because a mechanically ventilated patient with cardiogenic shock being treated with an intra-aortic balloon pump would benefit most from having a Vigileo pulse contour cardiac output monitoring system. This device provides continuous cardiac output monitoring and can help guide hemodynamic management in critically ill patients, especially those with hemodynamic instability like cardiogenic shock. It allows for real-time adjustments of fluid and vasoactive medications to optimize cardiac output and tissue perfusion. Choice A is incorrect because a patient with a history of aortic insufficiency and postoperative myocardial infarction may not require continuous cardiac output monitoring like the patient in choice B. Choice C is incorrect as the patient with atrial fibrillation and paroxysmal supraventricular tachycardia does not necessarily need cardiac output monitoring. Choice D is also incorrect as a mechanically ventilated patient following repair of an acute bowel obstruction may not require continuous cardiac output monitoring unless there are specific complications.

Correct Answer: A

Rationale: The correct answer is A: Restlessness. Restlessness is a common behavioral indicator of anxiety in patients. In this scenario, a patient who is orally intubated and on a ventilator may not be able to verbally express anxiety, making restlessness a more prominent sign. Verbalization may not be possible due to intubation. While increased respiratory rate can be a symptom of anxiety, it is also a common physiological response in patients on mechanical ventilation. A Glasgow Coma Scale score of 3 indicates severe impairment of consciousness, not specifically anxiety.

Correct Answer: D

Rationale: The correct answer is D: Initiate CPR and call a code. In this scenario, the patient is critically ill with ventricular tachycardia, a life-threatening arrhythmia. Since there is no "do not resuscitate" order, the appropriate nursing action is to initiate CPR immediately to attempt to restore the patient's cardiac function and circulation. Calling a code will ensure that a team of healthcare providers can respond promptly with necessary interventions. Options A and B involve unnecessary delays in potentially life-saving interventions. Option C is incorrect as withholding intubation can compromise the patient's airway and oxygenation. Thus, option D is the most appropriate action to prioritize the patient's safety and well-being in this critical situation.

Correct Answer: B

Rationale: The correct answer is B: Improvement in symptoms and quality of life. In palliative care, the primary focus is on enhancing the patient's quality of life by managing symptoms and providing comfort. This is achieved through effective symptom control, psychosocial support, and improving overall well-being. Complete resolution of the underlying disease (A) is often not possible in palliative care as the focus shifts from curative treatments to comfort care. Increased adherence to curative treatments (C) may not be the main goal in palliative care, as the emphasis is on improving the patient's comfort rather than prolonging life. Achievement of long-term survival goals (D) is not typically the primary outcome in palliative care, as the focus is on providing support and care for patients with life-limiting illnesses.
