Critical Care Nursing NCLEX Questions

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: C

Rationale: The correct answer is C: Considers factors related to safe patient care. The scenario involves the nurse discussing the patient's living will with the physician, which is essential for ensuring safe patient care by following the patient's preferences. This aligns with the AACN standard of considering factors related to safe patient care, as the nurse is actively involving all relevant parties in decision-making to provide care that is in line with the patient's wishes. Explanation of why other choices are incorrect: A: Acquires and maintains current knowledge of practice - While important, this choice does not directly relate to the scenario where the focus is on safe patient care through communication and collaboration. B: Acts ethically on behalf of the patient and family - While ethics are important, the scenario is more about following the patient's wishes as outlined in the living will rather than making ethical decisions. D: Uses clinical inquiry and integrates research findings in practice - While valuable in nursing practice, this choice does not directly apply to the scenario where

Correct Answer: A

Rationale: The correct answer is A: Bilateral infiltrates on chest x-ray study. ARDS diagnosis requires bilateral infiltrates on chest x-ray, indicative of non-cardiogenic pulmonary edema. Choice B, decreased cardiac output, is not a diagnostic criterion for ARDS. Choice C, PaO2/FiO2 ratio of less than 200, is a key diagnostic criteria for ARDS, indicating severe hypoxemia. Choice D, PAOP of more than 18 mm Hg, is used to differentiate between cardiogenic and non-cardiogenic causes of pulmonary edema, but it is not a direct diagnostic criterion for ARDS.

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: B

Rationale: The correct answer is B: Hypoventilation. A PaCO2 of 48 mm Hg indicates an elevated level of carbon dioxide in the blood, which is typically seen in hypoventilation where the lungs are not effectively removing CO2. Hypoventilation leads to respiratory acidosis. Option A is incorrect because hyperventilation would decrease PaCO2 levels. Option C is incorrect as it does not directly relate to PaCO2 levels. Option D is incorrect as increased excretion of HCO3- would not directly affect PaCO2 levels.
