Critical Care Nursing NCLEX Questions Questions
Question 1 of 5
The nurse is caring for a patient in acute respiratory failure and understands that the patient should be positioned (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: high Fowler's position. This position promotes optimal lung expansion by allowing the chest to expand fully, improving oxygenation. It also helps reduce the work of breathing. Side lying with the head of the bed elevated (B) may not provide the same level of lung expansion. Sitting in a chair (C) may not be suitable for a patient in acute respiratory failure as it may not provide adequate support for breathing. Supine with the bed flat (D) can worsen respiratory distress by limiting lung expansion.
Question 2 of 5
The nurse is preparing to obtain a pulmonary artery occlusion pressure (PAOP) reading for a patient who is mechanically ventilated. Ensuring that the aaibri-rbf.lcuoimd/ teinstt erface is at the level of the phlebostatic axis, what is the best nursing action?
Correct Answer: C
Rationale: The correct answer is C because placing the patient with the head of the bed elevated 30 degrees is the best position for obtaining an accurate PAOP reading. Elevating the head of the bed helps to align the phlebostatic axis with the atrium, ensuring an accurate measurement of PAOP. This position reduces the impact of hydrostatic pressure on the reading. Options A and D are incorrect because the supine position and recording during exhalation or just before the increase in pressures during inhalation can lead to inaccurate readings. Option B is incorrect because documenting the average PAOP after three measurements does not address the importance of positioning for accuracy.
Question 3 of 5
The charge nurse has a Vigileo pulse contour cardiac output monitoring system available for use in the surgical intensive care unit. For which patient isa buisrbe.c oomf /ttehsits device most appropriate?
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.
Question 4 of 5
Upon entering the room of a patient with a right radial arte rial line, the nurse assesses the waveform to be slightly dampened and notices blood to bea bbirabc.ckoemd/te ustp into the pressure tubing. What is the best action by the nurse?
Correct Answer: B
Rationale: The correct answer is B: Disconnect the flush system from the arterial line catheter. This action is necessary to prevent air from entering the patient's bloodstream, which can lead to air embolism. By disconnecting the flush system, the nurse stops the flow of air and ensures patient safety. Checking the inflation volume of the pressurized bag (A) is not the immediate concern in this situation. Zero referencing the transducer system (C) is unrelated to the issue of air entering the arterial line. Reducing the number of stopcocks in the flush system tubing (D) does not address the immediate risk of air embolism.
Question 5 of 5
Which nursing actions are most important for a patient witahb irab .croigmh/tte srta dial arterial line? (Select all that apply.)
Correct Answer: A
Rationale: Step 1: Checking circulation to the right hand is crucial for assessing perfusion and detecting potential complications. Step 2: Arterial line placement can compromise blood flow, leading to ischemia if circulation is impaired. Step 3: Monitoring circulation every 2 hours allows for early detection of issues and prompt intervention. Step 4: This action ensures patient safety and prevents complications. Summary: - Choice B is incorrect as pressurized flush solution can increase the risk of complications. - Choice C is incorrect as monitoring the waveform is important but not the most critical action. - Choice D is incorrect as limb restraints can impede circulation and are unnecessary in this scenario.
