N212 Comprehensive Practice Exam with Rationales |
Questions and Answers | Latest Update
A COMPREHENSIVE ATI-STYLE PRACTICE EXAM based directly on your N212 Test 2
content. These mirror how ATI and nursing instructors structure questions: clinical scenarios,
prioritization, lab interpretation, and “negative wording” traps.
(Includes somne rationales)
ACID–BASE & ABG INTERPRETATION
1. A patient’s ABG results show:
pH 7.30, PaCO₂ 52 mmHg, HCO₃ 26 mEq/L.
How should the nurse interpret this?
A. Metabolic acidosis
B. Respiratory acidosis
C. Metabolic alkalosis
D. Respiratory alkalosis
Answer: B - Rationale: pH is acidic and CO₂ is elevated → respiratory acidosis.
2. Which ABG represents respiratory alkalosis?
A. pH 7.48, CO₂ 28
B. pH 7.29, HCO₃ 18
C. pH 7.50, HCO₃ 35
D. pH 7.31, CO₂ 52
Answer: A- Rationale: High pH + low CO₂ = respiratory alkalosis.
3. Which finding would the nurse expect in a patient hyperventilating due to anxiety?
A. Increased PaCO₂
B. Decreased pH
C. Decreased PaCO₂
D. Increased bicarbonate
Answer: C - Rationale: Hyperventilation blows off CO₂ → respiratory alkalosis.
, CIRRHOSIS & LIVER FAILURE
4. A patient with cirrhosis develops confusion and hand-flapping tremors. Which lab value
is most likely elevated?
A. Albumin
B. Ammonia
C. Hemoglobin
D. Calcium
Answer: B - Rationale: Ammonia causes hepatic encephalopathy.
5. Which lab result indicates impaired clotting in liver failure?
A. Decreased INR
B. Increased bilirubin
C. Increased PT/INR
D. Decreased ALT
Answer: C
6. Which clinical finding is an EARLY sign of cirrhosis?
A. Ascites
B. Asterixis
C. Fatigue
D. Hematemesis
Answer: C
DEHYDRATION & SODIUM
7. Which finding indicates dehydration?
A. Urine specific gravity 1.010
B. Hematocrit 32%
C. Urine specific gravity 1.035
D. Sodium 130 mEq/L
Answer: C
