Cardiac Vascular Nursing Exam Quality Control & Assurance 3

Question 1

A cardiac unit uses statistical process control (SPC) charts to monitor post-operative atrial fibrillation rates. A nurse sees seven consecutive data points below the mean. What does this pattern indicate?

Accepted Answer

A special cause requiring investigation

Answer

Seven consecutive points on one side of the mean is a Western Electric rule violation indicating a non-random special cause signal requiring investigation.

Question 2

Which organization accredits cardiac catheterization laboratories and sets quality standards that include door-to-balloon time benchmarks?

Accepted Answer

The Joint Commission (TJC)

Answer

The Joint Commission accredits hospitals and sets Accreditation Standards including STEMI performance measures such as door-to-balloon time.

Question 3

A cardiovascular nurse is auditing informed consent documentation for cardiac catheterization procedures. Which finding would be the most critical quality concern?

Accepted Answer

Consent obtained by the scrub technician rather than the physician

Answer

Informed consent for invasive procedures must be obtained by the performing physician, as it requires explanation of risks, benefits, and alternatives.

Question 4

A Pareto chart is used in a cardiac ICU quality project. The chart shows that line disconnection, medication labeling errors, and alarm fatigue together account for 78% of all safety events. How should this data guide improvement priorities?

Accepted Answer

Focus initial improvement efforts on the top three issues driving the majority of events

Answer

The Pareto principle (80/20 rule) directs teams to prioritize the vital few causes that produce the majority of adverse events for maximum impact.

Question 5

A cardiovascular unit implements bedside shift report (BSR) as a quality improvement strategy. Which patient outcome is BSR primarily designed to improve?

Accepted Answer

Improvement in patient safety through enhanced communication and engagement

Answer

Bedside shift report improves patient safety by enhancing nurse-to-nurse communication, patient situational awareness, and patient engagement in their own care.
