Critical Care Nursing NCLEX Questions

Correct Answer: A

Rationale: The correct answer is A: contact the provider and expect a prescription for a normal saline bolus. The patient is showing signs of hypovolemia with decreased urine output, low blood pressure, and elevated heart rate. This indicates inadequate perfusion and potential hypovolemic shock. Administering a normal saline bolus will help restore intravascular volume and improve perfusion. Waiting for the provider to make rounds (option B) could delay necessary intervention. Continuing to evaluate urine output for 2 more hours (option C) is not appropriate given the patient's current condition. Ignoring the urine output (option D) is dangerous as it could lead to further complications.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): When the low-pressure alarm sounds for a patient with an arterial line, the nurse should assess for cardiac dysrhythmias first. This is because a sudden drop in pressure could indicate a serious issue affecting the heart's ability to pump effectively. Identifying and addressing any cardiac dysrhythmias promptly is crucial for patient safety. Summary of Incorrect Choices: A: Fast flush of the arterial line - This would not address the underlying cause of the low-pressure alarm and may not be necessary. B: Check the left hand for pallor - While assessing perfusion is important, it is not the priority when the alarm indicates a potential cardiac issue. D: Rezero the monitoring equipment - While important for accuracy, it is not the priority when the alarm indicates a potential cardiac concern.

Correct Answer: B

Rationale: The correct answer is B: She is in the exhaustion stage of the general adaptation syndrome to stress. Rationale: 1. In the exhaustion stage, the body's resources are depleted due to prolonged stress, leading to fatigue and reduced ability to cope. 2. The elderly woman is likely experiencing high levels of stress due to her granddaughter's critical condition. 3. Managing toddlers while dealing with the emotional distress of a loved one in the ICU can be overwhelming, causing exhaustion. 4. This explanation aligns with the symptoms of fatigue and difficulty managing the children observed by the nurse. Summary: A: Incorrect. Senility is a cognitive condition unrelated to the stress of the situation. C: Incorrect. Assuming a caregiver role can be stressful, but it does not explain the observed exhaustion. D: Incorrect. Macular degeneration affects vision, not the ability to manage stress and children.

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: 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.
