AACN Cardiac Surgery Certification Examination Practice Test
Cardiac surgery nursing focuses on the changing needs of patients before and after procedures involving the heart and major vessels. Practice questions address bedside assessment and immediate care, including arterial-line waveform checks, oxygen support, urine-output changes, vascular-access complications, and temporary pacing concerns.
Exam overview
About the AACN Cardiac Surgery Certification Examination Exam
Clinical decisions after cardiac surgery depend on distinguishing equipment problems from patient deterioration and acting on the most urgent finding. Relevant practice skills include checking arterial pressure measurements against another source, recognizing signs of IV infiltration, and responding to reduced urine output after correcting an obvious drainage obstruction. Other scenarios involve interpreting heparin monitoring, supporting ventilation when oxygenation is below an individualized target, and identifying possible pacemaker sensing problems. The question bank also touches on care related to infective endocarditis evaluation, infection prevention, and ventricular assist device alarms. These situations call for focused assessment, awareness of device function, and timely escalation to the appropriate clinical team.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A patient with an arterial catheter after cardiac surgery has a damped waveform and a blood pressure reading that differs substantially from the cuff measurement. Which action is appropriate first?
Show answer
Correct answer: BA damped waveform or implausible pressure may reflect a problem with the measurement system. Check the tubing, connections, air, and transducer leveling and zeroing before interpreting the value or changing treatment. Do not force-flush or remove the catheter solely on this basis.
A patient is being evaluated for possible infective endocarditis before valve surgery. Which test is generally important to obtain before starting antibiotics when the patient’s condition permits?
Show answer
Correct answer: AObtaining multiple blood-culture sets from separate venipuncture sites before antimicrobial therapy, when clinically feasible, improves the chance of identifying the causative organism and helps guide treatment. Urgent therapy should not be delayed in an unstable patient when doing so would be unsafe.
A patient recovering from cardiac surgery has a peripheral intravenous catheter. The site becomes swollen, cool, and pale during infusion, and the patient reports discomfort. What complication is most likely?
Show answer
Correct answer: BSwelling, coolness, pallor, and discomfort at a peripheral infusion site are characteristic of infiltration, in which fluid enters surrounding tissue. Stop the infusion and follow the facility’s assessment and treatment procedure for the infusate involved.
A patient with chronic obstructive pulmonary disease is recovering after cardiac surgery. Which approach best supports safe oxygen therapy when an individualized oxygen target has been prescribed?
Show answer
Correct answer: AOxygen should be titrated to the patient-specific prescribed target with ongoing assessment. A history of carbon dioxide retention is not a reason to withhold oxygen when hypoxemia is present. Pulse oximetry does not measure ventilation or carbon dioxide level, so clinical assessment and other tests may be needed.
A patient recovering from cardiac surgery asks why staff encourage hand hygiene before touching the incision or central-line dressing. Which response is most accurate?
Show answer
Correct answer: AHand hygiene reduces transmission of microorganisms and is a core measure for preventing healthcare-associated infections. It does not eliminate all infection risk and does not replace aseptic technique or other indicated precautions.
A patient with a ventricular assist device reports a sudden decrease in device flow and becomes lightheaded. Which assessment should be prioritized while promptly notifying the device team?
Show answer
Correct answer: AA change in displayed device flow can reflect a device issue or a change in preload, afterload, rhythm, or patient condition. The immediate priority is to assess the patient’s perfusion and stability while following device-specific emergency procedures and contacting the trained team. Do not disconnect or reset equipment without authorized direction.
A patient recovering from cardiac surgery has a sudden decrease in urine output. The urinary catheter tubing is visibly kinked beneath the patient’s leg. What is the most appropriate initial action?
Show answer
Correct answer: BA visible mechanical obstruction should be corrected first, followed by reassessment of urine output and the patient’s clinical status. If output remains low after patency is restored, further evaluation for perfusion or renal causes is needed.
How to use this practice test
The free practice bank contains 50 published questions. Each session presents up to 20 questions selected at random and shows results when the session ends. Use the scenarios to rehearse prioritization and clinical reasoning; review any missed items by identifying the assessment finding or device issue that should guide the next action.
Preparation tips
- For arterial-line scenarios, compare the waveform and pressure reading with the clinical picture and another measurement; assess the monitoring setup before relying on a discrepant value.
- Review signs of IV infiltration and the first nursing responses to a swollen, cool, pale infusion site with discomfort.
- Practice linking low oxygen saturation and shallow breathing with supportive respiratory interventions, while respecting the patient's prescribed oxygen target and contraindications.
- Distinguish pacemaker undersensing from other pacing problems by comparing pacing spikes with intrinsic atrial activity and the device's sensing mode.
- For sudden ventricular assist device flow changes, connect the alarm with symptoms such as lightheadedness and prioritize focused patient and device assessment while escalating promptly.
