ATI RN Comprehensive Predictor Exam V2
| 2026 Q&A with Rationale (ATI RN
Comprehensive Predictor Exam 2026)
1. A nurse is caring for a client with heart failure who is receiving furosemide. Which of the
following findings indicates the medication is effective?
A. Increased heart rate
B. Weight loss of 1 kg (2.2 lb) in 24 hours
C. Decreased serum potassium level
D. Increased blood pressure
Correct Answer: B
Rationale: Furosemide is a loop diuretic used to reduce fluid volume in clients with heart
failure. A weight loss of 1 kg in 24 hours is a reliable indicator of fluid loss and effective
treatment. Other indicators include decreased edema and improved breath sounds.
2. A nurse is monitoring a client who has a prescription for digoxin. Which of the following
clinical findings should the nurse identify as a manifestation of digoxin toxicity?
A. Hyperkalemia
B. Increased appetite
C. Visual disturbances such as yellow halos
,D. Hypertension
Correct Answer: C
Rationale: Visual disturbances, specifically yellow or green halos, are classic signs of
digoxin toxicity. Other symptoms include bradycardia, anorexia, nausea, and vomiting. The
nurse should check the serum digoxin levels and potassium levels if toxicity is suspected.
3. A client is admitted to the emergency department with a suspected myocardial infarction.
Select the immediate nursing action, the most relevant laboratory test, and the expected ECG
change for this client.
A. Action: Ambulate; Lab: WBC; ECG: T-wave inversion
B. Action: Start IV; Lab: BUN; ECG: QRS narrowing
C. Action: Give Morphine; Lab: Troponin; ECG: ST-segment elevation
D. Action: Assess pupils; Lab: ALT; ECG: P-wave absence
Correct Answer: C
Rationale: Immediate treatment for MI includes the MONA protocol: Morphine, Oxygen,
Nitroglycerin, and Aspirin. Troponin is the most specific cardiac marker for identifying
myocardial damage. ST-segment elevation is a hallmark sign of myocardial infarction on a
12-lead ECG.
,4. A nurse is preparing to administer lithium carbonate to a client with bipolar disorder.
Which of the following findings should the nurse report to the provider as a sign of lithium
toxicity?
A. Mild thirst
B. Polyuria
C. Fine hand tremors
D. Coarse hand tremors
Correct Answer: D
Rationale: Coarse hand tremors are a sign of advanced lithium toxicity, whereas fine hand
tremors are a common side effect of lithium therapy. Other signs of toxicity include ataxia,
persistent gastrointestinal upset, and mental confusion. Lithium levels must be monitored
closely to prevent toxicity.
5. A nurse is caring for a client with a new prescription for warfarin. Which of the following
laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?
A. INR
B. aPTT
C. Platelet count
D. Hemoglobin
Correct Answer: A
, Rationale: The International Normalized Ratio (INR) is the standard measurement used to
monitor the effectiveness of warfarin therapy. The typical target range for most clients on
warfarin is 2.0 to 3.0. aPTT is used to monitor heparin therapy, not warfarin.
6. A nurse is reviewing the plan of care for a client who is 1 day postoperative following a
total hip arthroplasty. Which of the following interventions should the nurse include?
A. Maintain the client’s legs in an adducted position
B. Keep the client’s hip flexed at 110 degrees when sitting
C. Encourage the client to cross their legs at the ankles
D. Place an abductor pillow between the client’s legs
Correct Answer: D
Rationale: An abductor pillow is used to maintain the legs in an abducted position, which
prevents the hip from dislocating after surgery. Clients should avoid hip flexion beyond 90
degrees and should never cross their legs. These precautions are essential for the integrity
of the new joint.
7. A client with Type 1 Diabetes Mellitus presents with Kussmaul respirations and a fruity
breath odor. Which of the following conditions should the nurse anticipate based on these
findings?
A. Hypoglycemia
B. Diabetic Ketoacidosis (DKA)
C. Hyperglycemic Hyperosmolar State (HHS)
