CRAT Patient Monitoring and Safety 3

Question 1

Which factor most significantly affects the quality of ECG signal transmission in telemetry monitoring?

Accepted Answer

Distance from the transmitter to the receiver and physical barriers between them

Answer

The patient's heart rate

Answer

The brand of ECG machine

Answer

The time of day monitoring occurs

Question 2

A patient on anticoagulation therapy develops a new atrial fibrillation. Why is anticoagulation particularly important in this setting?

Accepted Answer

Atrial fibrillation promotes thrombus formation in the left atrial appendage, creating risk of embolic stroke

Answer

Anticoagulation controls the ventricular rate in atrial fibrillation

Answer

Anticoagulation prevents atrial fibrillation from recurring

Answer

Anticoagulation improves cardiac output in atrial fibrillation

Question 3

The RACE protocol in rapid rhythm assessment stands for which systematic approach?

Accepted Answer

Rate, Atrial activity, Conduction (PR interval), Everything else (QRS, ST, QT)

Answer

Rhythm, Arrhythmia, Cardiac output, Electrophysiology

Answer

Rate, Axis, Complexes, ECG interpretation

Answer

Regularity, Amplitude, Conduction, Evaluation

Question 4

Which action by the monitor technician is most appropriate when observing a new sustained run of wide complex tachycardia at 200 bpm in a monitored patient?

Accepted Answer

Immediately notify the bedside nurse and document the rhythm strip with date and time

Answer

Silence the alarm and wait to see if the rhythm self-terminates

Answer

Independently increase the patient's IV fluids

Answer

Call pharmacy to obtain adenosine

Question 5

Hospital alarm fatigue is a significant patient safety concern because it most commonly leads to which outcome?

Accepted Answer

Clinicians becoming desensitized and ignoring alarms, potentially missing critical events

Answer

Alarms becoming louder over time

Answer

Patients developing anxiety about their monitoring

Answer

Reduced accuracy of ECG interpretation

Question 6

Documentation of rhythm strips in clinical monitoring should include which essential elements?

Accepted Answer

Patient name/ID, date and time, lead(s) monitored, rhythm interpretation, clinical context, and documenting clinician's identification

Answer

Only the rhythm interpretation

Answer

Only the patient name and date

Answer

Heart rate and QRS duration only
