ATI RN Exit Exam 2023
1. A nurse is caring 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/min
- 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 (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.
2. A client is receiving heparin therapy. Which of the following laboratory results indicates the client is receiving an effective dose of heparin?
- A. INR 1.5
- B. aPTT 60 seconds
- C. Platelets 150,000/mm³
- D. Potassium 4.0 mEq/L
Correct answer: B
Rationale: An aPTT of 60 seconds indicates the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for a clot to form, and a therapeutic range for heparin therapy is usually 1.5 to 2 times the control value, which is around 60-80 seconds. An INR of 1.5 is not related to heparin therapy, as it is commonly used to monitor warfarin therapy. Platelet count and potassium levels are not direct indicators of the effectiveness of heparin therapy.
3. A client with a new diagnosis of heart failure is receiving teaching from a nurse. Which of the following instructions should the nurse include?
- A. Limit sodium intake to 4 grams per day.
- B. Weigh yourself daily to monitor for fluid retention.
- C. Drink 2 liters of water each day.
- D. Increase physical activity gradually.
Correct answer: B
Rationale: The correct answer is B. Weighing oneself daily is crucial in monitoring fluid retention, a key aspect in managing heart failure. This helps in detecting early signs of fluid buildup, prompting timely interventions. Choice A is incorrect as the recommended sodium intake for heart failure clients is usually lower, around 2-3 grams daily. Choice C is incorrect because excessive water intake can worsen fluid retention in heart failure. Choice D is incorrect as clients with heart failure should consult healthcare providers before significantly altering their physical activity levels.
4. A healthcare provider is educating a client with type 2 diabetes mellitus about managing blood glucose levels. Which of the following statements by the client indicates a need for further teaching?
- A. I will monitor my blood glucose levels every morning.
- B. I will stop taking my insulin if my blood glucose level is below 200 mg/dL.
- C. I will take my insulin as prescribed, even if I am feeling well.
- D. I will eat more simple carbohydrates if my blood glucose level is low.
Correct answer: D
Rationale: The correct answer is D because consuming more simple carbohydrates when blood glucose levels are low can cause a rapid spike in blood sugar levels, leading to potential complications. Clients with type 2 diabetes should eat complex carbohydrates or foods that help stabilize blood sugar levels when experiencing hypoglycemia. Choices A, B, and C demonstrate understanding of monitoring blood glucose levels regularly, not stopping insulin without consulting a healthcare provider, and adhering to insulin therapy even when feeling well, which are all appropriate actions for managing diabetes.
5. A nurse is planning care for a client who has Alzheimer's disease and demonstrates confusion and wandering behavior. Which of the following should the nurse include in the plan of care?
- A. Place the client in seclusion when she is confused.
- B. Request a prescription for PRN restraints when the client is wandering.
- C. Dim the lighting in the client's room.
- D. Leave one side rail up on the client's bed.
Correct answer: C
Rationale: The correct answer is to dim the lighting in the client's room. Dim lighting can help reduce confusion and agitation in clients with Alzheimer's disease. Placing the client in seclusion (Choice A) is not recommended as it can lead to feelings of isolation and distress. Requesting PRN restraints (Choice B) should be avoided in clients with Alzheimer's as it can increase agitation and pose safety risks. Leaving one side rail up on the client's bed (Choice D) may not directly address the client's confusion and wandering behavior.
