• This comprehensive practice exam contains 200 NGN-style and traditional
multiple-choice questions designed to evaluate critical thinking, clinical judgment,
and evidence-based nursing care across all major adult medical-surgical nursing
domains.
• Use this material to identify knowledge gaps, practice time management under
exam conditions, review detailed rationales to reinforce concepts, and build
confidence through systematic topic review and repeated practice.

1. A 68-year-old client with acute myocardial infarction (AMI) is experiencing
chest pain radiating to the left arm. Which assessment finding is most
indicative of cardiogenic shock?
A) Blood pressure of 140/90 mmHg with heart rate of 78 bpm
B) Urine output of 20 mL/hour with cool, clammy skin
,C) Respiratory rate of 16 breaths/minute with clear lung sounds
D) Troponin level elevated at 2.5 ng/mL with normal lactate
E) Alert and oriented to person, place, and time with no complaints
✓ CORRECT ANSWER: B) Urine output of 20 mL/hour with cool, clammy skin
RATIONALE: Cardiogenic shock occurs when the heart fails to pump adequate
blood volume to perfuse vital organs. Clinical manifestations include decreased
urine output (less than 0.5 mL/kg/hour or <30 mL/hour for most adults), cool and
clammy skin from peripheral vasoconstriction, altered mental status, and metabolic
acidosis. Option B demonstrates the classic compensatory response of the body
attempting to maintain perfusion to vital organs by shunting blood away from
peripheral tissues. Options A, C, D, and E represent relatively stable or normal
findings that would not indicate shock state.
2. A 55-year-old client is admitted with acute decompensated heart failure.
The nurse administers furosemide IV. Which finding indicates the medication
is having the intended therapeutic effect?
A) Increased blood pressure by 20 mmHg systolic
B) Decreased respiratory rate from 28 to 18 breaths/minute
C) Increased serum sodium level from 138 to 142 mEq/L
D) Increased heart rate from 88 to 110 bpm
E) Increased creatinine level from 1.1 to 1.8 mg/dL
✓ CORRECT ANSWER: B) Decreased respiratory rate from 28 to 18
breaths/minute
RATIONALE: Furosemide is a loop diuretic used to reduce fluid overload in heart
failure by promoting sodium and water excretion. In acute decompensated heart
failure with pulmonary edema, the elevated respiratory rate (tachypnea) results
from fluid in the alveoli reducing gas exchange. As furosemide removes excess
fluid, pulmonary edema decreases, oxygenation improves, and respiratory rate
,normalizes. Option A is incorrect because diuretics typically lower blood pressure.
Option D shows increased heart rate, indicating inadequate perfusion. Option E
demonstrates worsening renal function. Option C shows hypernatremia, which may
occur with diuretic use but is not the primary intended effect.
3. A 72-year-old client with chronic atrial fibrillation is prescribed warfarin.
The client asks why they need this medication. Which nursing response best
explains the purpose?
A) To convert atrial fibrillation to normal sinus rhythm
B) To slow the ventricular response rate during atrial fibrillation episodes
C) To prevent blood clot formation in the heart due to irregular rhythm
D) To strengthen cardiac muscle contractions
E) To reduce inflammation in the cardiac tissue
✓ CORRECT ANSWER: C) To prevent blood clot formation in the heart due to
irregular rhythm
RATIONALE: Atrial fibrillation causes irregular, chaotic atrial contractions that
prevent effective atrial emptying, allowing blood to pool in the atrial appendage
and increasing thrombus formation risk. Warfarin, an anticoagulant, prevents clot
formation by inhibiting vitamin K-dependent clotting factors. This reduces stroke
risk, a major complication of atrial fibrillation. Option A describes antiarrhythmic
therapy. Option B describes rate-control agents like beta-blockers. Option D and E
do not address the actual therapeutic purpose of anticoagulation in this clinical
scenario.
4. A 45-year-old client presents to the emergency department with sudden
onset of severe, tearing chest pain radiating to the back and diaphoresis.
Blood pressure is 190/110 mmHg. Which condition should the nurse suspect?
A) Acute myocardial infarction with anterior wall involvement
, B) Aortic dissection
C) Pulmonary embolism with hemodynamic instability
D) Acute pericarditis with tamponade
E) Spontaneous pneumothorax with tension component
✓ CORRECT ANSWER: B) Aortic dissection
RATIONALE: The clinical presentation of sudden onset, severe, tearing (ripping)
chest pain radiating to the back, accompanied by severe hypertension and
diaphoresis is classic for acute aortic dissection. This is a medical emergency
requiring immediate intervention. The quality of pain (tearing/ripping), radiation
pattern (to back), and hemodynamic findings (hypertension) differentiate this from
other conditions. Myocardial infarction typically presents with crushing chest pain,
not tearing. Pulmonary embolism presents with pleuritic pain. Pericarditis pain is
positional and pleuritic. Pneumothorax does not typically cause this pain pattern or
degree of hypertension.
5. A 58-year-old client recovering from coronary artery bypass graft (CABG)
surgery is 2 days postoperative. The nurse notes increased drainage from the
mediastinal chest tube (200 mL/hour of bright red blood). Which action should
the nurse take first?
A) Document the finding and notify the surgeon immediately
B) Increase IV fluid replacement to maintain blood pressure
C) Administer packed red blood cells per standing orders
D) Clamp the chest tube to prevent further drainage
E) Continue monitoring and reassess in 1 hour
✓ CORRECT ANSWER: A) Document the finding and notify the surgeon
immediately
RATIONALE: Excessive mediastinal drainage (>200 mL/hour of bright red blood) in
the immediate postoperative period following CABG indicates possible bleeding
