ATI RN ADULT MED-SURG PROCTORED EXAM 2026 | VERIFIED QUESTIONS,
CORRECT ANSWERS & DETAILED RATIONALES
DOCUMENT OVERVIEW
• This comprehensive practice exam contains 200 verified questions with detailed
rationales covering all major adult med-surg nursing concepts tested on the ATI
proctored examination
• Study these questions by reviewing each rationale carefully, focusing on the "why"
behind correct answers rather than memorizing options—this builds clinical
reasoning essential for real-world nursing practice
QUESTIONS
1. A nurse is caring for a client with acute myocardial infarction (MI). Which of
the following medications should the nurse expect to administer
immediately?
A) Digoxin for heart rate control
B) Lisinopril for blood pressure management
C) Aspirin for antiplatelet effect
D) Amiodarone for rhythm stabilization
E) Furosemide for fluid overload
✓ CORRECT ANSWER: C) Aspirin for antiplatelet effect
,RATIONALE: Aspirin is one of the first medications administered in acute MI
because it has an immediate antiplatelet effect, preventing further clot formation
and reducing mortality. It should be given within minutes of symptom onset. While
other medications are important in MI management, they are not the immediate
first-line agents. Digoxin is rarely used acutely, lisinopril is given after stabilization,
amiodarone is for dysrhythmias if present, and furosemide is for specific fluid
overload situations.
2. A nurse is assessing a client with heart failure. Which finding indicates
acute decompensation?
A) Mild dyspnea with exertion only
B) Orthopnea and paroxysmal nocturnal dyspnea
C) Stable weight over past week
D) Peripheral edema that improves with elevation
E) Capillary refill less than 2 seconds
✓ CORRECT ANSWER: B) Orthopnea and paroxysmal nocturnal dyspnea
RATIONALE: Orthopnea (shortness of breath when lying flat) and paroxysmal
nocturnal dyspnea (sudden awakening at night with severe dyspnea) are classic
signs of acute decompensated heart failure, indicating pulmonary congestion.
These findings suggest the condition is worsening and require immediate
intervention. Mild dyspnea with exertion is expected in chronic HF, stable weight
and improved peripheral edema with elevation are positive signs, and normal
capillary refill indicates adequate perfusion.
3. A nurse is monitoring a client receiving intravenous nitroglycerin for chest
pain. Which adverse effect requires immediate intervention?
A) Mild headache
B) Flushed skin
,C) Severe hypotension with dizziness
D) Reflex tachycardia
E) Slight chest discomfort
✓ CORRECT ANSWER: C) Severe hypotension with dizziness
RATIONALE: Severe hypotension is a critical adverse effect of nitroglycerin that can
lead to inadequate coronary perfusion and myocardial ischemia—the opposite of
the desired effect. This requires immediate intervention including dose reduction,
fluid administration, and position changes. Mild headache, flushed skin, and reflex
tachycardia are common expected side effects. Slight chest discomfort may indicate
the medication needs adjustment but is not as immediately dangerous as
hypotension.
4. A client with atrial fibrillation is prescribed warfarin. Which finding
indicates the client understands discharge teaching?
A) The client states they will stop warfarin if they feel better
B) The client demonstrates knowledge of dietary vitamin K consistency
C) The client reports taking warfarin with antacids for better absorption
D) The client plans to use aspirin for minor aches and pains
E) The client will have INR checked only if symptoms develop
✓ CORRECT ANSWER: B) The client demonstrates knowledge of dietary vitamin
K consistency
RATIONALE: Consistent vitamin K intake is critical for warfarin therapy because
vitamin K is a cofactor for warfarin metabolism. Varying vitamin K intake causes
fluctuations in INR levels. Clients should maintain consistent intake, not increase or
decrease it. Warfarin should never be stopped without provider direction, it should
not be taken with antacids (which reduce absorption), aspirin increases bleeding
risk, and regular INR monitoring is essential—not just when symptoms occur.
, 5. A nurse is caring for a client post-operative day 1 following abdominal
surgery. The client has a nasogastric (NG) tube. Which finding requires
immediate reporting to the provider?
A) Minimal gastric drainage of clear fluid
B) Absence of bowel sounds
C) Sudden large amount of bright red drainage
D) Client reports mild nausea
E) NG tube taped securely in place
✓ CORRECT ANSWER: C) Sudden large amount of bright red drainage
RATIONALE: Sudden large amounts of bright red drainage from an NG tube post-
operatively may indicate active bleeding from the surgical site or GI tract, which is a
medical emergency requiring immediate intervention and possible transfusion.
Minimal clear drainage is expected post-op, absent bowel sounds are normal
immediately after surgery, mild nausea is common, and secure taping is
appropriate nursing care. Bright red blood (rather than coffee-ground appearance)
indicates active bleeding.
6. A nurse is assessing a client with COPD during an exacerbation. Which
arterial blood gas (ABG) result is most concerning?
A) pH 7.35, PaCO2 48, HCO3 24
B) pH 7.42, PaCO2 35, HCO3 22
C) pH 7.30, PaCO2 65, HCO3 28
D) pH 7.45, PaCO2 38, HCO3 26
E) pH 7.40, PaCO2 40, HCO3 24
✓ CORRECT ANSWER: C) pH 7.30, PaCO2 65, HCO3 28
RATIONALE: This ABG shows respiratory acidosis with CO2 retention (PaCO2 65)
and compensatory metabolic alkalosis (HCO3 28), which indicates severe
