Critical Care Nursing Questions and Answers PDF

Correct Answer: C

Rationale: The correct answer is C because the synergy model of practice emphasizes considering the needs of patients and their families, which in turn drives nursing competency. This approach recognizes that patient care is not just about the individual but also about the broader support system. This holistic viewpoint helps nurses tailor their care to meet the unique needs of each patient and their family, ultimately leading to better outcomes. Choices A, B, and D are incorrect: A: Allowing unrestricted visiting for the patient 24 hours is not directly related to the focus of the synergy model which is more about patient-centered care. B: Providing holistic and alternative therapies is a valid approach, but it is not the primary focus of the synergy model. D: Addressing the patients' needs for energy and support is important but does not capture the comprehensive nature of the synergy model which encompasses the needs of both patients and their families.

Correct Answer: C

Rationale: The most appropriate nursing action in this scenario is choice C: Provide support for the patient�s decision and ensure comfort measures. This is because the patient is in hospice care, indicating a focus on comfort and quality of life rather than aggressive treatments. By respecting the patient�s decision and providing comfort measures, the nurse promotes dignity and autonomy. Choices A and B are not suitable as they go against the patient's wishes and may cause distress. Choice D, while important, is not the immediate priority when the patient is not in pain and has chosen to refuse food and fluids. Overall, choice C aligns with the principles of hospice care and prioritizes the patient's comfort and autonomy.

Correct Answer: B

Rationale: The correct answer is B: Ensure that a sterile field is maintained during the insertion procedure. This is the priority nursing action because maintaining a sterile field is crucial to prevent infection during the invasive procedure. The nurse must follow strict aseptic technique to reduce the risk of introducing bacteria into the patient's bloodstream. All other choices are incorrect: A: Addressing the patient's anxiety is important but not the priority during the insertion procedure. C: Inflating the balloon is a specific action that should be performed by the physician, not the nurse. D: While monitoring the patient's cardiac rhythm is important, ensuring the sterile field takes precedence to prevent complications.

Correct Answer: A

Rationale: The correct answer is A: Alveoli collapse and atelectasis occurs. When fluid is present in the alveoli, it impairs the surface tension necessary for the alveoli to remain open, leading to collapse and atelectasis. This prevents proper gas exchange, resulting in hypoxemia. Choice B is incorrect because impaired gas diffusion typically occurs with conditions affecting the alveolar-capillary membrane, not fluid in the alveoli. Choice C is incorrect as hypoventilation refers to decreased ventilation, not specifically related to fluid in the alveoli. Choice D is incorrect as fluid in the alveoli is not a direct indicator of heart failure.

Correct Answer: B

Rationale: The correct answer is B because it shows understanding that the PAC helps in managing fluid therapy effectively. The PAC measures pressures in the heart and lungs, guiding fluid management. Choice A is incorrect as the PAC is not primarily for IV fluid administration. Choice C shows understanding of the catheter placement but not its purpose. Choice D is incorrect as the PAC is not for the heart to heal but to monitor cardiac status.
