The Critical Care Nursing Exam for Senior BSN students is designed to evaluate comprehensive knowledge and
clinical decision-making skills essential for managing critically ill patients in intensive care settings. This
assessment covers advanced pathophysiology, evidence-based interventions, pharmacological management, and
ethical considerations inherent to high-acuity environments. The examination utilizes multiple-choice and
scenario-based questions to simulate real-world clinical situations, requiring candidates to apply critical thinking,
prioritize care, and demonstrate sound judgment under pressure. Emphasis is placed on the integration of
theoretical knowledge with practical application, ensuring that future critical care nurses can deliver safe,
competent, and compassionate care while adhering to professional standards, regulatory requirements, and
interdisciplinary collaboration protocols.
SECTION ONE: QUESTIONS 1–100
Question 1
A 68-year-old patient in the ICU develops sudden onset of jugular venous distension, muffled heart sounds, and
,hypotension following cardiac catheterization. Which condition should the nurse suspect first?
A. Acute myocardial infarction
B. Cardiac tamponade
C. Pulmonary embolism
D. Aortic dissection
🟢 Correct answer: B
🔴 RATIONALE: Beck's triad (elevated JVD, muffled heart sounds, and hypotension) is the classic presentation of
cardiac tamponade, which can occur as a complication of cardiac catheterization due to coronary artery or
cardiac chamber perforation. The nurse must recognize this immediately as a medical emergency requiring
pericardiocentesis.
Question 2
When managing a patient receiving high-dose vasopressin for septic shock, which electrolyte imbalance should
the nurse monitor most closely?
A. Hypernatremia
B. Hypokalemia
, C. Hyponatremia
D. Hypercalcemia
🟢 Correct answer: C
🔴 RATIONALE: Vasopressin (antidiuretic hormone) promotes water reabsorption in the renal collecting ducts,
which can lead to dilutional hyponatremia. The nurse must monitor serum sodium levels closely and assess for
signs of water intoxication, including confusion, headache, and seizures.
Question 3
A patient with acute respiratory distress syndrome (ARDS) is on mechanical ventilation with a PEEP of 12 cm
H2O and FiO2 of 0.80. The nurse notes a sudden drop in SpO2 from 94% to 82%, increased peak airway
pressures, and absent breath sounds on the left side. What is the priority nursing intervention?
A. Increase the FiO2 to 1.0
B. Prepare for immediate chest tube insertion
C. Perform endotracheal suctioning
D. Administer a bronchodilator
🟢 Correct answer: B
