ATI Exit Exam 2023
1. A nurse is caring for a client who has a new prescription for warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the medication?
- A. Hemoglobin
- B. Platelet count
- C. Prothrombin time (PT)
- D. International normalized ratio (INR)
Correct answer: D
Rationale: The correct answer is D, International normalized ratio (INR). INR is used to monitor the therapeutic effect of warfarin, an anticoagulant medication. Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors. Monitoring the INR helps assess how well the medication is working to prevent blood clots. Choices A, B, and C are not specific indicators for monitoring the effectiveness of warfarin. Hemoglobin levels primarily assess the oxygen-carrying capacity of red blood cells, platelet count evaluates the clotting ability of blood, and PT measures the time it takes for blood to clot. While these values are important for overall health assessment, they do not directly reflect the anticoagulant effects of warfarin.
2. A client is receiving chemotherapy and is being taught about preventing infection. Which of the following instructions should the nurse include?
- A. Take your temperature daily.
- B. Avoid fresh fruits and vegetables.
- C. Limit your intake of high-protein foods.
- D. Increase your intake of high-fat foods.
Correct answer: B
Rationale: Clients receiving chemotherapy are instructed to avoid fresh fruits and vegetables to lower the risk of infection. Fresh produce may harbor bacteria or other pathogens that could be harmful to individuals with compromised immune systems. Taking the temperature daily may be important but is not directly related to preventing infection. Limiting high-protein foods is not necessary unless there are specific dietary restrictions due to the treatment plan. Increasing the intake of high-fat foods is not recommended during chemotherapy as a high-fat diet may lead to other health issues.
3. A client has a new prescription for furosemide. Which of the following laboratory values should the nurse monitor?
- A. Potassium
- B. Sodium
- C. Calcium
- D. Hemoglobin
Correct answer: A
Rationale: When a client is prescribed furosemide, monitoring potassium levels is crucial due to the drug's potential to cause hypokalemia. Furosemide is a loop diuretic that promotes potassium excretion in the urine, leading to a risk of low potassium levels. Monitoring potassium levels helps in detecting and preventing hypokalemia, which can result in adverse effects like cardiac dysrhythmias. Sodium, calcium, and hemoglobin levels are usually not directly affected by furosemide, making them less pertinent for monitoring in this specific scenario.
4. A nurse is caring for a client who has bipolar disorder and is experiencing acute mania. The nurse obtained a verbal prescription for restraints. Which of the following actions should the nurse take?
- A. Request a renewal of the prescription every 8 hours.
- B. Check the client's peripheral pulse rate every 30 minutes.
- C. Obtain a prescription for restraint within 4 hours.
- D. Document the client's condition every 15 minutes.
Correct answer: C
Rationale: Obtaining a prescription for restraint within 4 hours is the correct action when managing restraints in a client with acute mania. This timeframe ensures that the use of restraints is promptly evaluated and authorized by a healthcare provider. Requesting a renewal of the prescription every 8 hours (Choice A) is not necessary and may delay appropriate care. Checking the client's peripheral pulse rate every 30 minutes (Choice B) is important but not the immediate priority when dealing with obtaining a prescription for restraints. Documenting the client's condition every 15 minutes (Choice D) is essential for monitoring, but the priority is to secure a prescription for restraints promptly.
5. A nurse is assessing a client who has heart failure and is receiving digoxin. Which of the following findings should the nurse identify as an indication of digoxin toxicity?
- A. Bradycardia.
- B. Tachycardia.
- C. Nausea.
- D. Blurred vision.
Correct answer: D
Rationale: Corrected Rationale: Blurred vision is a classic sign of digoxin toxicity, indicating a potential overdose. It is crucial to recognize this symptom promptly and report it to the healthcare provider for immediate intervention. Bradycardia and nausea are common side effects of digoxin but not specific indicators of toxicity. Tachycardia is unlikely in digoxin toxicity since it usually causes a decrease in heart rate.
