ATI RN Custom Exams Set 4
1. The client diagnosed with thalassemia, a hereditary anemia, is to receive a transfusion of packed RBCs. The cross-match reveals the presence of antibodies that cannot be cross-matched. Which precaution should the nurse implement when initiating the transfusion?
- A. Start the transfusion at 10-15 mL per hour for 15-30 minutes
- B. Re-crossmatch the blood until the antibodies are identified
- C. Have the client sign a permit to receive uncrossmatched blood
- D. Have the unlicensed nursing assistant stay with the client
Correct answer: A
Rationale: Starting the transfusion slowly at 10-15 mL per hour for 15-30 minutes is the correct precaution to implement when the cross-match reveals the presence of antibodies that cannot be cross-matched. This allows the nurse to monitor for any adverse reactions due to the presence of antibodies. Re-crossmatching the blood until the antibodies are identified is not practical and may delay the transfusion, potentially compromising the patient's condition. Having the client sign a permit to receive uncrossmatched blood is not the best course of action as the focus should be on ensuring a safe transfusion. Having an unlicensed nursing assistant stay with the client does not address the specific precaution needed to manage a transfusion in the presence of antibodies.
2. You are performing an admission assessment on an older adult patient newly admitted for end-stage liver disease. What principle should guide your assessment of the patients skin turgor?
- A. Overhydration is common among healthy older adults.
- B. Dehydration causes the skin to appear spongy
- C. Inelastic skin turgor is a normal part of aging
- D. Skin turgor cannot be assessed in patients over 70.
Correct answer: Inelastic skin turgor is a normal part of aging
Rationale:
3. You are caring for a patient with a diagnosis of pancreatitis. The patient was admitted from a homeless shelter and is a vague historian. The patient appears malnourished and on day 3 of the patients admission total parenteral nutrition (TPN) has been started. Why would you know to start the infusion of TPN slowly?
- A. Patients receiving TPN are at risk for hypercalcemia if calories are started too rapidly.
- B. Malnourished patients receiving parenteral nutrition are at risk for hypophosphatemia if calories are started too aggressively.
- C. Malnourished patients who receive fluids too rapidly are at risk for hypernatremia.
- D. Patients receiving TPN need a slow initiation of treatment in order to allow digestive enzymes to accumulate
Correct answer: Malnourished patients receiving parenteral nutrition are at risk for hypophosphatemia if calories are started too aggressively.
Rationale:
4. What is the primary goal of a root cause analysis (RCA) in healthcare?
- A. To assign blame for errors
- B. To prevent future errors by identifying underlying causes
- C. To improve patient satisfaction
- D. To analyze the financial impact of errors
Correct answer: B
Rationale: The correct answer is B: 'To prevent future errors by identifying underlying causes.' Root cause analysis (RCA) in healthcare aims to delve deep into the factors contributing to an error to prevent its recurrence. Choice A is incorrect as RCA focuses on identifying system issues, not blaming individuals. Choice C is incorrect as while improving patient satisfaction may result from the process, it is not the primary goal. Choice D is incorrect as the main focus of RCA is not financial analysis but rather improving patient safety.
5. Which lab value is critical to monitor in patients receiving warfarin therapy?
- A. Monitor INR
- B. Monitor potassium levels
- C. Monitor platelet count
- D. Monitor sodium levels
Correct answer: A
Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial to monitor in patients receiving warfarin therapy. INR measures the blood's ability to clot and is used to ensure that patients are within the therapeutic range for warfarin therapy. This is important to prevent both clotting disorders and bleeding complications. Monitoring potassium levels (choice B) is not directly related to warfarin therapy. Platelet count (choice C) and sodium levels (choice D) are important parameters but are not as critical to monitor specifically for patients on warfarin therapy.
