Critical Care Nursing Questions and Answers PDF

Correct Answer: B

Rationale: The correct answer is B because informed consent requires the patient to have knowledge and competence to make a decision. This involves understanding the risks, benefits, and alternatives of the proposed treatment. Choice A is incorrect as it pertains to a physical ability unrelated to decision-making. Choice C is incorrect as consent must be verbal or written, not just nodding. Choice D is incorrect as consent can be obtained in various ways, not specifically through reading and writing in English.

Correct Answer: D

Rationale: The correct answer is D: Administer furosemide 20 mg intravenously. In this scenario, the patient is hypotensive with a low cardiac output, low CVP, and low PAOP, indicating cardiogenic shock. Administering furosemide, a diuretic, can worsen the patient's condition by further decreasing preload. This can lead to a decrease in cardiac output and exacerbate the shock state. The other options are more appropriate: A: Titrate supplemental oxygen to achieve a SpO > 94% - Correct, as improving oxygenation is essential in cardiogenic shock. B: Infuse 500 mL 0.9% normal saline over 1 hour - Correct, as fluid resuscitation may be necessary to improve perfusion. C: Obtain arterial blood gas and serum electrolytes - Correct, as these tests provide valuable information about the patient's oxygenation and electrolyte balance.

Correct Answer: D

Rationale: The correct answer is D: Deal with issues and not personalities. This guideline is important because it focuses on resolving the conflict based on the actual problem at hand, rather than personal biases or emotions. By addressing the issues causing the argument, the nurse can help the UAPs find a fair and logical solution. A: Requiring the UAPs to reach a compromise may not address the root cause of the conflict and could lead to further disagreements. B: Weighing the consequences is important but may not be as effective in resolving the conflict as directly addressing the issues. C: Encouraging humor may temporarily diffuse the situation but may not lead to a lasting resolution.

Correct Answer: C

Rationale: The correct answer is C: True collaboration. In this scenario, the physician consults with the nurse to understand the situation and collaborates on the best course of action for the patient's care. This demonstrates effective teamwork, communication, and mutual respect between healthcare professionals, which are key components of a healthy work environment. Choice A (Skilled communication) is not the best answer because while communication between the physician and nurse is important, the focus in this scenario is more on collaboration and teamwork. Choice B (Appropriate staffing) is not the best answer as the scenario does not specifically address staffing levels but rather the interaction and collaboration between the physician and nurse. Choice D (Recognizing signs of imminent stroke and paging the physician) is incorrect as it is unrelated to the scenario described, which is about the physician and nurse collaborating on patient care.

Correct Answer: B

Rationale: The correct answer is B: Dimming lights during the night. This intervention helps reduce stress by creating a more calming environment, promoting rest and sleep. Constant observation (choice A) may increase stress due to lack of privacy. Frequent group rounds (choice C) may disrupt rest. Use of tile floors (choice D) is unrelated to addressing noise and light stress.
