DAANCE Patient Monitoring Techniques 2

Question 1

A patient pulse oximeter reads 91% SpO2 during sedation. The FIRST clinical response should be:

Accepted Answer

Stimulate the patient, increase oxygen flow, and assess airway patency

Answer

SpO2 below 94 percent requires immediate action: stimulate the patient, verify airway patency, increase oxygen delivery, and assess breathing - do not wait.

Question 2

The NIBP (non-invasive blood pressure) cuff should be applied to which site for routine sedation monitoring?

Accepted Answer

Upper arm, 2 to 3 cm above the antecubital fossa

Answer

The standard NIBP cuff placement is on the upper arm with the lower cuff edge 2 to 3 cm above the antecubital fossa, aligning the bladder over the brachial artery.

Question 3

Which ECG lead is most commonly monitored during office-based dental sedation for routine rhythm detection?

Accepted Answer

Lead II

Answer

Lead II is parallel to the cardiac electrical axis and provides the clearest P-wave and QRS morphology for rhythm analysis during routine monitoring.

Question 4

Precordial stethoscope monitoring during sedation provides continuous assessment of:

Accepted Answer

Heart and breath sounds simultaneously

Answer

A precordial or esophageal stethoscope transmits both cardiac and pulmonary sounds simultaneously.

Question 5

Which factor most commonly causes falsely LOW pulse oximetry readings (SpO2 underestimation)?

Accepted Answer

Peripheral vasoconstriction and poor perfusion to the probe site

Answer

Peripheral vasoconstriction from hypothermia, hypotension, or vasopressors reduces pulsatile blood flow at the probe site, causing low signal quality and falsely low or unreliable SpO2 readings.
