ATI RN Comprehensive Exit Exam
1. A nurse is planning care for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?
- A. Glomerular filtration rate of 14 mL/minute
- B. BUN 16 mg/dL
- C. Serum magnesium 1.8 mg/dL
- D. Serum phosphorus 4.0 mg/dL
Correct answer: A
Rationale: A glomerular filtration rate of 14 mL/minute indicates severe kidney dysfunction, necessitating hemodialysis. The other options, BUN of 16 mg/dL, serum magnesium of 1.8 mg/dL, and serum phosphorus of 4.0 mg/dL, are within normal ranges and do not serve as indications for hemodialysis.
2. A client who has a new diagnosis of tuberculosis should be placed in which type of room to prevent the spread of airborne pathogens?
- A. Administer isoniazid by mouth daily.
- B. Place the client in droplet isolation.
- C. Wear a surgical mask when transporting the client.
- D. Place the client in a negative pressure room.
Correct answer: D
Rationale: Clients diagnosed with tuberculosis should be placed in a negative pressure room to prevent the spread of airborne pathogens. Option A is incorrect because administering isoniazid is a treatment for tuberculosis, not a preventive measure related to infection control. Option B is incorrect as droplet isolation is used for diseases transmitted through respiratory droplets, not airborne pathogens like tuberculosis. Option C is incorrect as wearing a surgical mask is not sufficient to prevent the spread of tuberculosis in healthcare settings; placing the client in a negative pressure room is the most effective measure.
3. A client with asthma is being taught how to use a peak flow meter by a nurse. Which of the following instructions should the nurse include?
- A. Blow as hard as possible into the mouthpiece.
- B. Exhale quickly and forcefully after taking a deep breath.
- C. Inhale as deeply as possible and then blow into the mouthpiece.
- D. Take a deep breath and hold it for 5 seconds before exhaling.
Correct answer: B
Rationale: The correct answer is B because the client should exhale quickly and forcefully into the peak flow meter after taking a deep breath to measure peak expiratory flow. Choice A is incorrect as blowing as hard as possible may not provide an accurate reading. Choice C is incorrect because inhaling deeply before blowing can affect the results. Choice D is incorrect as holding the breath before exhaling is not part of using a peak flow meter.
4. A nurse is reviewing the medical record of a client who is receiving heparin to treat deep vein thrombosis (DVT). Which of the following findings should the nurse report to the provider?
- A. aPTT of 38 seconds
- B. Hemoglobin of 15 g/dL
- C. Platelet count of 80,000/mm3
- D. INR of 1.0
Correct answer: C
Rationale: A platelet count of 80,000/mm3 is below the normal range and should be reported to the provider due to the risk of bleeding. Heparin can cause a rare but serious side effect known as heparin-induced thrombocytopenia, leading to a decrease in platelet count and an increased risk of bleeding. The aPTT of 38 seconds, hemoglobin of 15 g/dL, and an INR of 1.0 are within normal ranges and not directly concerning in this scenario. Platelet count is crucial to monitor in clients receiving heparin therapy to ensure adequate clotting function and prevent bleeding complications.
5. What is the correct method to teach a patient about self-administration of insulin?
- A. Inject into the upper arm
- B. Rotate injection sites
- C. Use a 45-degree angle for injection
- D. Use a 90-degree angle for injection
Correct answer: D
Rationale: The correct method to teach a patient about self-administration of insulin is to use a 90-degree angle for injection. This angle ensures proper subcutaneous administration of insulin, which is essential for effective absorption. Injecting into the upper arm (Choice A) is not recommended for insulin administration. While rotating injection sites (Choice B) is important to prevent lipodystrophy, the angle of injection is crucial for proper insulin delivery. Using a 45-degree angle (Choice C) is more suitable for intramuscular injections, not for subcutaneous insulin injections.
