Critical Care Nursing NCLEX Questions

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: A

Rationale: The correct answer is A: A patient with a red tag. In triage, red tags indicate patients with life-threatening injuries who require immediate attention. The nurse must assess this patient first to provide necessary interventions. Patients with blue tags are considered urgent but stable, black tags are deceased or beyond help, and yellow tags are for delayed treatment. Assessing the red-tagged patient first ensures prompt care for those in critical condition.

Correct Answer: D

Rationale: The correct answer is D. When rewarming a hypothermic patient, the goal is to gradually increase their core temperature. A core temperature of 94�F (34.4�C) is still below the normal range, but it indicates that the rewarming process is working. Shivering (A) is a normal response to rewarming. A decrease in blood pressure (B) may be expected due to peripheral vasodilation during rewarming. Developing atrial fibrillation (C) may be a concern but does not necessarily indicate that rewarming should be discontinued. Therefore, choice D is correct as it signifies progress in the rewarming process.

Correct Answer: C

Rationale: The correct answer is C because individualized visitation meets the unique needs of patients and family members, promoting holistic care and emotional support. Choice A is incorrect as strictly restricted visiting hours may hinder family involvement in care. Choice B is incorrect as children can provide comfort and support. Choice D is incorrect as unrestricted visiting may disrupt patient rest and care routines.

Correct Answer: C

Rationale: The correct response is C: Your pain medication is already at the highest possible dose. This response acknowledges the patient's pain and reassures them that they are already receiving the maximum safe amount of pain medication. By stating this, the nurse is validating the patient's experience and showing empathy. It is important for the nurse to communicate clearly about the medication to manage the patient's expectations. Choice A is incorrect as it dismisses the patient's pain and can come across as insensitive. Choice B may be well-intentioned but does not address the immediate concern of the patient's pain. Choice D is irrelevant to the patient's statement about pain and does not offer any immediate support or reassurance regarding the pain management.
