RN ATI COMPREHENSIVE EXIT EXAM
(VERSIONS 1-4) QUESTION AND ANSWERS
WITH REVISED EXPLANATIONS AND
RATIONALES 2025-2026 PASS GUIDE
This premium nursing bundle contains comprehensive multiple-
choice practice questions with detailed, bolded rationales tailored
specifically for the 2025/2026 RN ATI Comprehensive Exit Exam.
Covering critical medical-surgical, pharmacological, pediatric, and
maternal-newborn concepts, it applies vital test-taking frameworks
like ABCs, Maslow’s hierarchy, and Next-Generation NCLEX (NGN)
safety rules. It serves as an ultimate high-yield resource designed to
ensure a guaranteed pass and top-tier scores on institutional exit
predictors.
1. A nurse is caring for a client who is 4 hours postoperative following
a subtotal thyroidectomy. Which of the following findings is the
highest priority for the nurse to report to the provider?
A) Mild pain at the incision site rated 3/10
B) Laryngeal stridor
C) Client reporting feeling tired and sleepy
D) Incisional dressing with a dime-sized spot of serosanguineous drainage
Answer: B
Rationale: Using the Airway, Breathing, Circulation (ABC) priority
framework, laryngeal stridor indicates an acute upper airway obstruction.
This can occur post-thyroidectomy due to laryngeal nerve damage,
,swelling, or hypocalcemic tetany, requiring immediate emergency
intervention.
2. A nurse is preparing to administer digoxin to a client who has heart
failure. Which of the following laboratory values should the nurse
review before administering the medication?
A) Serum sodium level
B) Serum potassium level
C) Blood urea nitrogen (BUN)
D) White blood cell (WBC) count
Answer: B
Rationale: Hypokalemia (serum potassium level less than 3.5 mEq/L)
increases the risk of digoxin toxicity and can precipitate fatal cardiac
arrhythmias. The nurse must check potassium levels and the apical pulse
for 1 full minute prior to administration.
3. A nurse is assessing a client who has a chest tube connected to a
water-seal drainage system. The nurse notes continuous bubbling in
the water-seal chamber. How should the nurse interpret this finding?
A) The system is functioning correctly.
B) There is an air leak in the system.
C) The client’s lung has fully re-expanded.
D) The suction pressure needs to be increased.
Answer: B
Rationale: Continuous bubbling in the water-seal chamber indicates an air
leak between the client and the drainage system. Intermittent bubbling is
normal during exhalation or coughing, but continuous bubbling requires
immediate troubleshooting to locate and seal the leak.
,4. A nurse is assessing a client who is receiving a continuous
intravenous infusion of heparin. Which of the following laboratory
values indicates that the therapy is within the therapeutic range?
A) INR of 2.5
B) Prothrombin time (PT) of 12 seconds
C) Activated partial thromboplastin time (aPTT) of 65 seconds
D) Platelet count of 100,000/mm³
Answer: C
Rationale: Heparin therapy effectiveness is monitored using the aPTT. A
therapeutic level is typically 1.5 to 2.5 times the normal baseline value
(normal baseline is roughly 30 to 40 seconds), making 65 seconds an
expected therapeutic finding. INR and PT are used to monitor oral warfarin
therapy.
5. A nurse is caring for a client who is in active labor and notes late
decelerations on the fetal monitor strip. Which of the following
actions should the nurse take first?
A) Administer oxygen at 2 L/min via nasal cannula.
B) Increase the rate of the oxytocin infusion.
C) Turn the client onto her left side.
D) Prepare the client for an immediate amniotomy.
Answer: C
Rationale: Late decelerations indicate uteroplacental insufficiency. The first
action the nurse should take is to position the client on her left side to
alleviate vena cava compression, maximize placental perfusion, and
increase oxygen delivery to the fetus.
, 6. A nurse is preparing to administer an intramuscular injection to an
infant who is 6 months old. Which of the following muscles should
the nurse select as the preferred injection site?
A) Deltoid
B) Dorsogluteal
C) Ventrogluteal
D) Vastus lateralis
Answer: D
Rationale: The vastus lateralis muscle is the largest, most developed
muscle mass in infants under 12 months of age and is free of major nerves
and blood vessels, making it the safest and preferred site for intramuscular
injections.
7. A nurse is teaching a client who has a new prescription for lithium
carbonate to treat bipolar disorder. Which of the following
instructions should the nurse include in the teaching?
A) Restrict sodium intake to less than 1,500 mg per day.
B) Maintain a consistent fluid intake of 2 to 3 liters daily.
C) Take the medication on an empty stomach.
D) Discontinue the medication as soon as mood stabilizes.
Answer: B
Rationale: Lithium is a salt, and low fluid or sodium intake can lead to
lithium retention, causing toxic levels to accumulate in the bloodstream.
Clients must maintain a normal, consistent sodium intake and drink 2,000
to 3,000 mL of water daily.
8. A nurse is evaluating a client who has a newly placed permanent
pacemaker. Which of the following findings indicates a complication
of the procedure?
