Critical Care Nursing NCLEX Questions

Correct Answer: B

Rationale: The correct answer is B because withdrawal is a common psychological response in the dying process. The nurse should explain to the son that his mother's lack of response may be her way of preparing to leave life. This response validates the son's concerns while providing reassurance. Choice A is incorrect because cutting back visits may not address the underlying issue of the mother's withdrawal. Choice C is incorrect because stimulating the mother may not be beneficial or appropriate in this situation. Choice D is incorrect because not all patients experience a lack of awareness at the end of life, and assuming so may not be helpful in this context.

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: A

Rationale: Step-by-step rationale for why choice A is correct: 1. Involving the family in patient care is crucial for holistic care. 2. Assessing family relationships helps identify support systems and potential conflicts. 3. Understanding family dynamics aids in creating a comprehensive care plan. 4. Family involvement can enhance patient outcomes and satisfaction. Summary of incorrect choices: B. Irrelevant, as the focus is on patient-centered care, not just fulfilling an assessment tool. C. Personal curiosity is not a valid reason for assessing family relationships in healthcare. D. Conducting research on family patterns does not directly impact the immediate care of the patient.

Correct Answer: B

Rationale: The correct answer is B: Obtain a Glasgow Coma Scale score. During the primary survey, assessing the patient's level of consciousness is crucial as it helps determine the severity of the injury and guides further management. The Glasgow Coma Scale is a standardized tool used to assess the level of consciousness based on eye opening, verbal response, and motor response. It provides valuable information about the patient's neurological status. A: Obtaining a complete set of vital signs is important but assessing the level of consciousness takes priority in this scenario. C: Asking about chronic medical conditions is important but not as critical as assessing the patient's level of consciousness during the primary survey. D: Attaching a cardiac electrocardiogram monitor is not necessary during the primary survey unless there are specific indications of cardiac issues, which are not evident in this case. In summary, obtaining a Glasgow Coma Scale score is essential for assessing the patient's level of consciousness and determining the severity of the injury during the primary survey.

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.
