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

Telemetry signal quality degrades with increasing distance from the receiver and when the patient moves behind walls, into elevators, or into areas with thick concrete or metal barriers that attenuate the radio frequency signal.

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

In atrial fibrillation, the left atrial appendage loses effective contractile function and blood pools, predisposing to thrombus formation that can embolize to the cerebral circulation, causing stroke.

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

The RACE mnemonic guides systematic ECG rhythm interpretation by evaluating Rate, Atrial activity (P waves), Conduction (PR interval), and Everything else including QRS and ST changes.

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

The monitor technician's critical role is immediate notification of clinical staff and accurate documentation — clinical interventions are the responsibility of licensed nurses and physicians.

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

Alarm fatigue occurs when excessive nuisance alarms cause clinicians to become habituated, muting alarms or delaying response, which has led to preventable patient deaths when true critical alarms are ignored.
