Correct Answer: C

Rationale: The correct answer is C: Cardiac output (CO) of 5 L/min. In cardiogenic shock, the primary goal of using an IABP is to improve cardiac output to ensure adequate perfusion to vital organs. A cardiac output of 5 L/min indicates adequate blood flow and perfusion. Choice A is incorrect as urine output is not a direct indicator of cardiac function. Choice B is incorrect as a heart rate of 110 beats/minute alone does not provide information on the effectiveness of the IABP in improving cardiac output. Choice D is incorrect as stroke volume alone does not provide a comprehensive assessment of overall cardiac function.

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: Contact the hospital’s interpreter service for someone to translate. This is the best option as it ensures accurate communication between the nurse, patient, and family. Hospital interpreters are trained professionals who can accurately convey medical information, ensuring understanding and informed decision-making. Using Google search (A) may result in inaccurate information and is not reliable for medical communication. Asking a resident (C) who is fluent may not guarantee accuracy in medical terminology. Using a young family member (D) as a translator can lead to miscommunication due to potential language barriers or lack of medical knowledge. Overall, option B is the most appropriate and ethical choice for effective communication in a healthcare setting.

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: C

Rationale: The correct answer is C: notify the provider immediately. The absence of bruit, thrill, and palpable distal pulses in a new arteriovenous fistula suggests potential complications like thrombosis or stenosis, requiring urgent intervention. Notifying the provider promptly allows for timely assessment and appropriate management to prevent further complications. Summary: A: Reassessing the patient in an hour may delay necessary intervention for a potentially serious issue. B: Raising the arm above the level of the patient’s heart does not address the underlying problem and may not improve the situation. D: Applying warm packs to the fistula site is not the appropriate intervention for the absence of bruit and thrill and may not address the underlying cause.
