Critical Care Nursing NCLEX Questions

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.

Correct Answer: B

Rationale: The correct answer is B because certification validates nurses' expert knowledge and practice. This is important as it ensures that nurses have the necessary skills and competence to provide high-quality care in critical care settings. Certification is voluntary and not mandated by government regulations (Choice C). It goes beyond demonstrating basic knowledge (Choice D) by confirming specialized expertise. While certification may garner positive publicity (Choice A), the primary benefit is the validation of advanced skills and knowledge.

Correct Answer: C

Rationale: Rationale: 1. Culture and religious beliefs can significantly impact end-of-life decision making by influencing values, beliefs, and preferences. 2. These factors may affect choices related to treatment options, quality of life, and spiritual aspects. 3. Different cultural backgrounds may lead to varying perspectives on autonomy, family involvement, and medical interventions. 4. Option A and B make generalizations based on race, which is not accurate as preferences can vary widely within any racial group. 5. Option D is incorrect as perspectives on end-of-life care can vary even within the same religious group due to individual beliefs and interpretations.

Correct Answer: D

Rationale: The correct answer is D. The first step in endotracheal intubation is to insert the endotracheal tube with a laryngoscope and blade to visualize the vocal cords and guide the tube into the trachea. This ensures proper placement of the tube for effective ventilation. Assessing the balloon symmetry (Choice A) and lung fields (Choice B) would come after the tube is successfully inserted. Inflating the balloon of the endotracheal tube (Choice C) should be the last step to secure the tube in place.

Correct Answer: C

Rationale: Rationale: - Improved collaboration enhances job satisfaction and reduces burnout, leading to increased staff retention. - Higher staff retention promotes continuity of care, improves team dynamics, and enhances patient outcomes. Summary: - A: Not directly related to collaboration, more about performance evaluation. - B: Manners may improve, but not the most important effect of collaboration. - D: Collaboration involves open communication, so less discussion in front of patients is not a positive outcome.
