Critical Care Nursing Questions and Answers PDF

Correct Answer: C

Rationale: The correct answer is C: Listen to the patient�s breath sounds. Moving from 22 cm to 25 cm may indicate ET tube migration. Checking breath sounds can confirm proper tube placement. A may not address the underlying issue. B could worsen the situation if the tube is misplaced. D is not urgent compared to assessing airway integrity.

Correct Answer: C

Rationale: The correct answer is C: intrarenal. The presence of sediment, crystals, and bacteria in the urinalysis indicates an issue originating within the kidney itself. This suggests a problem like a urinary tract infection or kidney stone causing the severe flank pain. Prerenal and postrenal conditions usually involve issues outside the kidney such as dehydration or urinary tract obstruction, which are not supported by the urinalysis findings. Choice D, not renal related, is incorrect as the symptoms and urinalysis results clearly point towards a renal issue.

Correct Answer: D

Rationale: The correct answer is D: Pulmonary artery wedge pressure (PAWP). This is crucial in monitoring a patient with a large anterior wall myocardial infarction as it provides information on left ventricular function and fluid status. A high PAWP may indicate left ventricular failure or fluid overload, requiring immediate intervention. A: Central venous pressure (CVP) is not as specific for assessing left ventricular function and may not provide accurate information in this scenario. B: Systemic vascular resistance (SVR) is important in assessing systemic blood flow, but it may not directly indicate left ventricular function in this case. C: Pulmonary vascular resistance (PVR) is more relevant in conditions affecting the pulmonary circulation and may not be as immediately informative in assessing left ventricular function in this context.

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: C

Rationale: The correct answer is C because inquiring about specific cultural rituals and preferences shows respect for the patient's cultural beliefs and values. By asking about these aspects, the nurse can provide care that aligns with the patient's cultural background, promoting comfort and understanding. This action also demonstrates a commitment to individualized care. Choice A is incorrect because standardized care may not always be culturally appropriate. Choice B is incorrect as avoiding discussions about death can hinder effective communication and support. Choice D is incorrect as advising families to strictly follow hospital guidelines may overlook the importance of cultural considerations in end-of-life care.
