Critical Care Nursing Questions and Answers PDF

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.

Correct Answer: C

Rationale: The correct answer is C because maintaining eye contact with the patient during explanations is a non-verbal way to show attentiveness and empathy, which can help reduce the patient's anxiety. This behavior demonstrates active listening and engagement, making the patient feel heard and understood. A: Staying in the patient's room to complete documentation is not an effective use of presence as it does not involve direct interaction with the patient. B: Having a conversation in the patient's room that excludes the patient is also not an effective use of presence as it does not involve engaging with the patient. D: Focusing on specific nursing care tasks while in the patient's room, although important, may not necessarily demonstrate presence in reducing the patient's anxiety.

Correct Answer: C

Rationale: The correct answer is C: Assessment. In the SBAR communication model, the nurse's information about the patient's history and vital signs falls under the Assessment component. This is because the nurse is providing a detailed evaluation of the patient's current condition based on objective data such as urine output, heart rate, blood pressure, and other key indicators. The nurse is analyzing the situation and forming a judgment that the patient is hypovolemic, indicating a fluid deficit. This assessment is crucial for informing further actions or interventions, such as increasing fluids or providing a fluid challenge. Summary of other choices: A: Situation - This choice would refer to a brief summary of the current situation without detailed analysis or interpretation. B: Background - This choice would involve providing relevant background information about the patient, such as medical history or recent procedures, but not the current assessment of the patient's condition. D: Recommendation - This choice would involve suggesting a course of action or treatment based on the assessment, which comes after

Correct Answer: D

Rationale: The correct answer is D because continuous venovenous hemodialysis combines ultrafiltration, convection, and dialysis techniques. Ultrafiltration removes excess fluid, convection helps in removing solutes, and dialysis involves the diffusion of solutes across a semipermeable membrane. This comprehensive approach ensures effective removal of both fluid and solutes in critically ill patients. Incorrect Answer Analysis: A: Removing fluids and solutes through convection alone is not the complete process in continuous venovenous hemodialysis. B: While volume overload is addressed, continuous venovenous hemodialysis involves more than just removing plasma water. C: Adding dialysate is not the primary method in continuous venovenous hemodialysis; it involves ultrafiltration, convection, and dialysis techniques.

Correct Answer: B

Rationale: The correct answer is B: Fighting the ventilator. This behavior indicates the patient is experiencing discomfort and struggling against the ventilator, suggesting a high likelihood of pain. The CPOT assesses pain through behaviors like grimacing, vocalization, and muscle tension, which are all present when a patient is fighting the ventilator. Absence of vocal sounds (Choice A) does not necessarily indicate pain as some patients may be silent even when in pain. Moving legs in bed (Choice C) could be due to restlessness rather than pain. Relaxed muscles in upper extremities (Choice D) do not reflect pain as the CPOT focuses on behaviors indicating discomfort.
