Critical Care Nursing NCLEX Questions

Correct Answer: B

Rationale: The correct answer is B: Liver. The nurse should monitor liver function in this client because acetaminophen is primarily metabolized in the liver. Alcohol abuse can also contribute to liver damage, increasing the risk of liver toxicity from acetaminophen. Monitoring liver function tests like AST, ALT, and bilirubin levels can help detect any liver damage early. Choice A, cardiorespiratory, is not directly related to acetaminophen or alcohol abuse in this scenario. Choice C, sensory, is not relevant to monitoring organ function in this context. Choice D, kidney, is not the primary concern because acetaminophen is mainly metabolized in the liver, and kidney function is not typically affected by acetaminophen use.

Correct Answer: C

Rationale: The correct answer is C: To identify and treat the underlying cause. The first priority of the nurse when critically ill patients exhibit signs of anxiety is to determine the root cause of the anxiety. By identifying and addressing the underlying cause, the nurse can effectively manage the patient's anxiety and prevent further complications. Administering medications without understanding the cause can mask the symptoms and lead to ineffective treatment. Reassessing the patient hourly may not address the root cause and could delay appropriate intervention. Pain medication may not be necessary if the anxiety is not related to pain. Treating the underlying cause ensures holistic and effective care for the patient.

Correct Answer: C

Rationale: The correct answer is C: Measure the patient�s urinary output every hour. This is crucial because monitoring urinary output is essential in assessing the patient�s renal function and the effectiveness of the intra-aortic balloon pump in improving cardiac output. Hourly measurement helps in early detection of any changes that may indicate complications. A: Positioning the patient supine at all times is not necessary and can lead to complications. B: Avoiding the use of anticoagulant medications is not appropriate as they are often necessary to prevent clot formation around the balloon pump. D: Providing a massive range of motion for all extremities is not recommended for a patient with an intra-aortic balloon pump as it can dislodge the device or cause harm.

Correct Answer: C

Rationale: Step 1: The objective is for the client to ingest at least 1000 mL of fluid between 7:00 am and 3:30 pm. Step 2: Choice C states that the client drinks 240 mL of fluid five times during the shift, totaling 1200 mL (240 mL x 5) which exceeds the required amount. Step 3: Therefore, choice C is the correct answer as it demonstrates successful achievement of the objective by ensuring the client has ingested enough fluid within the specified time frame. Step 4: Choices A, B, and D are incorrect as they do not directly address the specific objective of fluid intake set for the client. Option A focuses on intake and output, option B relates to abdominal comfort, and option D is about voiding, none of which directly address the specified objective of fluid ingestion.

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.
