ATI Comprehensive Exit Exam
1. A nurse is caring for a client who has a new prescription for warfarin. Which of the following laboratory tests should the nurse use to monitor the client's therapeutic response to the medication?
- A. INR
- B. aPTT
- C. Platelet count
- D. Hemoglobin A1C
Correct answer: A
Rationale: The correct answer is A: INR. The INR (International Normalized Ratio) is the laboratory test used to monitor the therapeutic response of warfarin. It helps ensure that the client's clotting time is within the desired range to prevent complications such as excessive bleeding or clotting. Choice B, aPTT (Activated Partial Thromboplastin Time), is not typically used to monitor warfarin therapy but rather for assessing heparin therapy. Choice C, Platelet count, assesses the number of platelets in the blood and is not specifically used to monitor warfarin therapy. Choice D, Hemoglobin A1C, is a test used to monitor long-term blood sugar control in diabetic patients and is not relevant to monitoring warfarin therapy.
2. A nurse is reviewing the laboratory results of a client who is receiving warfarin therapy for atrial fibrillation. Which of the following laboratory values should the nurse report to the provider?
- A. INR 1.8
- B. Hemoglobin 14 g/dL
- C. Platelets 175,000/mm³
- D. Potassium 3.8 mEq/L
Correct answer: A
Rationale: The correct answer is A. An INR of 1.8 is below the therapeutic range for a client receiving warfarin, indicating a potential risk of blood clots. This value should be reported to the provider for further evaluation and possible adjustment of the warfarin dosage. Choices B, C, and D are within normal ranges and do not directly relate to the effectiveness or safety of warfarin therapy in this scenario, making them less urgent to report.
3. A nurse is planning care for a client who has a new diagnosis of deep vein thrombosis (DVT). Which of the following interventions should the nurse include in the plan of care?
- A. Massage the affected extremity to promote circulation.
- B. Elevate the affected extremity.
- C. Apply cold packs to the affected extremity.
- D. Perform range-of-motion exercises on the affected extremity.
Correct answer: C
Rationale: The correct intervention for a client with DVT is to apply cold packs to the affected extremity. Cold packs can help reduce swelling and pain by constricting blood vessels. Massaging the affected extremity can dislodge a clot and worsen the condition. Elevating the affected extremity helps with blood flow but is not the priority intervention for DVT. Performing range-of-motion exercises on the affected extremity can also dislodge a clot and is contraindicated.
4. Four clients present to the emergency department. The nurse should plan to see which of the following clients first?
- A. A 6-year-old client with a dislocated left shoulder
- B. A 26-year-old client with sickle cell disease and severe joint pain
- C. A 76-year-old client who is confused, febrile, and has foul-smelling urine
- D. A 50-year-old client with slurred speech, disorientation, and headache
Correct answer: D
Rationale: The correct answer is D. A client presenting with symptoms of a stroke, such as slurred speech, disorientation, and headache, requires immediate attention due to the possibility of a neurological emergency. Choices A, B, and C, although concerning, do not present with symptoms as urgent as those of a potential stroke. Dislocated shoulder, sickle cell disease with joint pain, and confusion with febrile illness can be addressed after ensuring the client with stroke-like symptoms receives prompt evaluation and intervention.
5. What is the primary purpose of administering an antiemetic?
- A. To reduce nausea and vomiting
- B. To increase appetite
- C. To treat nausea caused by chemotherapy
- D. To treat allergic reactions
Correct answer: A
Rationale: The correct answer is A: 'To reduce nausea and vomiting.' Antiemetics are medications used to prevent or alleviate nausea and vomiting. While they may indirectly help with appetite by reducing the unpleasant symptoms that can lead to decreased food intake, their primary purpose is not to increase appetite (Choice B). Choice C, 'To treat nausea caused by chemotherapy,' is partly correct as antiemetics are commonly used to manage chemotherapy-induced nausea, but this is not their exclusive purpose. Choice D, 'To treat allergic reactions,' is incorrect as antiemetics are not primarily used for treating allergic reactions.
