• This 200-question ATI PN Comprehensive Predictor NGN 2026 practice exam
mirrors the format, difficulty, and clinical reasoning demands of the official exit
exam, covering all tested domains with detailed NGN-style scenarios.
• Study by attempting each question independently before reviewing the correct
answer and EXPERT RATIONALE below it — focus extra attention on any topic
where you miss two or more consecutive questions.
Question 1
A nurse is caring for a client who has heart failure and a new prescription for
furosemide 40 mg IV. Before administering the medication, which of the
following assessments is the priority?
A. Bowel sounds
B. Skin turgor
C. Serum potassium level
D. Blood pressure
E. Urine output from the past shift
C. Serum potassium level
Furosemide is a loop diuretic that causes potassium wasting. Hypokalemia
increases the risk of life-threatening cardiac dysrhythmias. Checking the serum
potassium level before administration is the priority to ensure it is within a safe
range before giving a medication that will lower it further.
Question 2
,A nurse is reviewing the laboratory results of a client who has chronic kidney
disease. Which of the following findings should the nurse report to the
provider?
A. Serum sodium 138 mEq/L
B. Serum calcium 9.0 mg/dL
C. Serum potassium 6.2 mEq/L
D. Serum creatinine 1.0 mg/dL
E. Hemoglobin 13.5 g/dL
C. Serum potassium 6.2 mEq/L
A serum potassium of 6.2 mEq/L is hyperkalemia (normal 3.5–5.0 mEq/L). In chronic
kidney disease, the kidneys cannot excrete potassium effectively. Hyperkalemia is a
medical emergency because it can cause fatal cardiac dysrhythmias including
ventricular fibrillation.
Question 3
A nurse is caring for a client who is receiving a continuous heparin infusion.
Which of the following laboratory values should the nurse monitor?
A. Prothrombin time (PT)
B. International normalized ratio (INR)
C. Activated partial thromboplastin time (aPTT)
D. Platelet count alone
E. Fibrinogen level
C. Activated partial thromboplastin time (aPTT)
Heparin affects the intrinsic clotting pathway and is monitored using the aPTT. The
therapeutic range is generally 60–100 seconds (1.5–2.5 times the normal value). PT
and INR are used to monitor warfarin therapy, not heparin.
,Question 4
A nurse is assessing a client who has pneumonia. Which of the following
findings should the nurse expect?
A. Hyperresonance on percussion
B. Decreased tactile fremitus
C. Bronchial breath sounds over the affected area
D. Absence of cough
E. Hypotension without fever
C. Bronchial breath sounds over the affected area
Pneumonia causes consolidation of lung tissue, which transmits bronchial breath
sounds to peripheral areas where they are not normally heard. Tactile fremitus is
increased (not decreased) over consolidated areas, and percussion produces
dullness rather than hyperresonance.
Question 5
A nurse is preparing to administer insulin glargine to a client. Which of the
following actions should the nurse take?
A. Mix it with regular insulin in the same syringe
B. Shake the vial vigorously before drawing
C. Administer it at the same time each day regardless of meals
D. Administer it only before breakfast
E. Use an IV infusion pump for administration
C. Administer it at the same time each day regardless of meals
, Insulin glargine (Lantus) is a long-acting basal insulin given subcutaneously once
daily at the same time each day. It should never be mixed with other insulins,
should never be shaken, and is not administered intravenously.
Question 6
A nurse is caring for a client who has a nasogastric tube for continuous
feedings. The nurse aspirates 280 mL of gastric residual. Which of the
following actions should the nurse take?
A. Continue the feeding at the current rate
B. Discard the residual and flush the tube
C. Hold the feeding and notify the provider
D. Increase the rate of the feeding
E. Reposition the client supine
C. Hold the feeding and notify the provider
A gastric residual volume greater than 250–500 mL (per facility policy) indicates
delayed gastric emptying and increases the risk of aspiration. The nurse should
hold the feeding, return the aspirate to prevent electrolyte loss, and notify the
provider.
Question 7
A nurse is caring for a client who has a new diagnosis of tuberculosis (TB).
Which of the following precautions should the nurse implement?
A. Contact precautions with gown and gloves
B. Droplet precautions with a surgical mask
C. Airborne precautions with a negative-pressure room
D. Protective (reverse) isolation
