PN ATI Comprehensive Predictor Questions
Question 1 of 5
What are the primary causes of respiratory acidosis?
Correct Answer: A
Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.
Question 2 of 5
A home health nurse is preparing for an initial visit with an older adult client who lives alone. Which of the following actions should the nurse take first?
Correct Answer: C
Rationale: Identifying environmental hazards in the client's home is the priority during the initial visit with an older adult living alone. This action is crucial to prevent accidents, falls, and ensure the client's safety. While educating the client about their medical diagnosis, referring them to a meal delivery program, and arranging transportation for follow-up appointments are essential, addressing environmental hazards takes precedence as it directly impacts the client's immediate safety and well-being.
Question 3 of 5
A nurse on an acute unit has received a change of shift report for 4 clients. Which of the following clients should the nurse assess first?
Correct Answer: B
Rationale: The correct answer is B because pallor in an extremity after a fracture could indicate compromised circulation, making it a priority for assessment. Choice A is not the priority as hypoactive bowel sounds in a client 1 hr postoperative, while concerning, do not indicate a life-threatening condition. Choice C, a client who had a cardiac catheterization 3 hr ago and has 3+ pedal pulses, indicates good perfusion and does not require immediate attention. Choice D, a client with an elevated AST level following the administration of azithromycin, may require further assessment but is not as urgent as the client with potential compromised circulation in choice B.
Question 4 of 5
A charge nurse on a medical-surgical unit is planning assignments for a licensed practical nurse (LPN) who has been sent from the postpartum unit due to a staffing shortage for the shift. Which of the following client assignments should the nurse delegate to the LPN?
Correct Answer: A
Rationale: The correct answer is A because the LPN can care for stable clients with complex needs, such as managing an NGT set to continuous suction. Choices B, C, and D involve clients with more acute conditions that require a higher level of assessment and intervention, making them unsuitable for delegation to an LPN. Choice B requires prompt evaluation of the shortness of breath in a client with a recent femur fracture, which is beyond the LPN's scope. Choice C involves a head injury and unequal pupils, indicating the need for neurological assessment and close monitoring. Choice D relates to a critically low hemoglobin level and the need for blood transfusion, requiring careful monitoring and potential intervention beyond the LPN's role.
Question 5 of 5
A nurse is caring for a client who is in the early stages of hypovolemic shock. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: In the early stages of hypovolemic shock, the body initiates compensatory mechanisms to maintain perfusion. One of these mechanisms is an increased respiratory rate to improve oxygen delivery. This helps to offset the decreased circulating blood volume. A heart rate of 60/min (choice A) is not expected in hypovolemic shock; instead, tachycardia is a common finding due to the body's attempt to maintain cardiac output. Increased urinary output (choice B) is not typically seen in hypovolemic shock as the body tries to conserve fluid. Hypothermia (choice D) is usually a late sign of shock when the body's compensatory mechanisms are failing, and perfusion is severely compromised.
