Cardiac Vascular Nursing Exam Technology & Digital Applications 4

Question 1

A nurse is troubleshooting a pulmonary artery catheter connected to a digital hemodynamic monitoring system. The displayed pulmonary artery occlusion pressure (PAOP) is consistently 0 mmHg. What is the most likely cause?

Accepted Answer

The balloon is ruptured or the catheter has migrated back to the right ventricle

Answer

A PAOP of 0 mmHg suggests balloon rupture preventing occlusion or catheter migration, both of which render the measurement invalid and require immediate assessment.

Question 2

Which digital documentation practice is most important when a cardiac nurse administers thrombolytic therapy for acute MI?

Accepted Answer

Record time of administration, dose, patient response, and any contraindications assessed

Answer

Time-sensitive thrombolytic therapy requires complete real-time documentation of administration details and patient response to support safe ongoing care and legal accountability.

Question 3

A hospital implements a digital early warning system (EWS) that automatically calculates a Modified Early Warning Score (MEWS). Which cardiovascular parameter contributes most to triggering a high MEWS alert?

Accepted Answer

Heart rate and systolic blood pressure deviations from baseline

Answer

Heart rate and systolic blood pressure are key vital sign components of MEWS calculations that, when significantly deranged, trigger escalation alerts for deteriorating cardiac patients.

Question 4

Which of the following best describes the function of a cardiac resynchronization therapy (CRT) device's remote optimization feature?

Accepted Answer

It allows non-invasive adjustment of AV and VV intervals based on transmitted device data

Answer

Remote CRT optimization allows clinicians to adjust atrioventricular and interventricular timing intervals using transmitted device data to maximize cardiac mechanical synchrony without an office visit.

Question 5

A nurse reviews a patient's continuous glucose monitoring (CGM) data integrated into the cardiac ICU's central monitoring system. Why is tight glycemic control particularly important for this population?

Accepted Answer

Hyperglycemia increases inflammation, impairs wound healing, and worsens outcomes post-cardiac surgery

Answer

Hyperglycemia in cardiac patients increases oxidative stress, promotes inflammation, and is independently associated with increased mortality and wound complications after cardiac surgery.
