CBET Patient Monitoring Systems 3

Question 1

What is a telemetry monitoring system and how does it differ from bedside monitoring?

Accepted Answer

Telemetry uses portable wireless transmitters on ambulatory patients, sending ECG data to a central station

Answer

Telemetry uses small portable wireless transmitters enabling continuous monitoring while patients walk around.

Question 2

What are the common sources of artifact in ECG monitoring and how can they be minimized?

Accepted Answer

Common sources include muscle tremor, movement, poor electrode contact, 60Hz interference, and respiratory drift, minimized through proper skin preparation

Answer

ECG artifact comes from multiple sources that can be minimized through proper electrode application and environmental controls.

Question 3

What is pulse transit time and how are newer patient monitors using it?

Accepted Answer

The time for a pulse wave to travel between two arterial sites, being explored for continuous cuff-less blood pressure estimation

Answer

PTT inversely correlates with blood pressure and enables continuous cuff-less BP estimation.

Question 4

Why is it important to verify alarm settings on a patient monitor at the beginning of each patient encounter?

Accepted Answer

Alarm limits must be individualized to prevent missed events and alarm fatigue from false alarms

Answer

Alarm limits must be individualized because default or previous patient settings may not be appropriate.

Question 5

What is the function of a fetal monitor and what two primary parameters does it continuously measure?

Accepted Answer

Fetal heart rate (FHR) and uterine contraction activity (tocometry)

Answer

A fetal monitor (cardiotocograph) measures fetal heart rate using Doppler ultrasound and uterine contractions using a tocodynamometer.
