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 is more accurate

Answer

Telemetry only works in operating rooms

Answer

Telemetry uses wired connections

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

Artifact only comes from equipment malfunction

Answer

Artifact is unavoidable

Answer

Only EMI causes artifact

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

The time between two heartbeats

Answer

The time a pulse oximeter takes to display

Answer

The time between ECG spike and respiration

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

Alarms are preset and never need adjustment

Answer

Alarms are only important in the ICU

Answer

Default settings are always 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

Maternal blood pressure and fetal weight

Answer

Fetal blood oxygen and respiratory rate

Answer

Maternal ECG and fetal movement

Question 6

What is bispectral index (BIS) monitoring and what does it measure?

Accepted Answer

A processed EEG parameter that quantifies anesthesia depth on a scale of 0 to 100

Answer

Blood flow velocity in cerebral arteries

Answer

Bilateral blood pressure comparison

Answer

Binocular visual stimulus response
