Question 1

The machine that monitors the patient's heartbeat during dental surgical procedures, IV sedation, and general anesthesia is a(n)&#10;A)electrocardiogram.&#10;B)pulse oximeter.&#10;C)capnograph.&#10;D)blood pressure monitor.

Accepted Answer

An electrocardiogram measures the electrical activity of the heartbeat and is usually used during dental surgical procedures, during IV sedation, and for general anesthesia. A pulse oximeter is used to measure the concentration of oxygen in the blood and to detect the pulse rate. A capnograph measures exhaled carbon dioxide. A blood pressure monitor measures only systolic and diastolic pressures.

Question 2

A capnograph is used for nonsedated patients.

Accepted Answer

A capnograph is used for patients who are sedated.

Question 3

What is the instrument used to hear the pulse, heartbeat, and systolic and diastolic pressure?&#10;A)Sphygmomanometer&#10;B)Pulse oximeter.&#10;C)Stethoscope.&#10;D)EKG.

Accepted Answer

To hear the pulse, heartbeat, and systolic and diastolic pressure, one would use a stethoscope. The sphygmomanometer is used to place pressure on the arteries so that the flow of blood can then be heard in the stethoscope. A pulse oximeter measures the concentration of oxygen in the blood. An EKG machine is used to measure the electrical activity of the heartbeat.

Question 4

What is the correct placement of the sphygmomanometer?&#10;A)At the elbow.&#10;B)Just below the elbow.&#10;C)Just above the elbow.&#10;D)2 inches above the bend of the elbow.

Accepted Answer

The blood pressure cuff should fit properly and be placed just above the bend in the elbow.

Question 5

What happens to the CO&#8322; level when a person hyperventilates?&#10;A)Increases.&#10;B)Decreases.

Accepted Answer

When a person hyperventilates, the CO₂ level goes down.

Question 6

What device should be used when a person is unresponsive (not breathing and no pulse is evident)?&#10;A)Capnograph.&#10;B)Pulse oximeter.&#10;C)Automated external defibrillator (AED).&#10;D)None of the above are correct.

Accepted Answer

An AED is used for emergency situations when a person is unresponsive, has no pulse, and is not breathing. A capnograph measures exhaled carbon dioxide. A pulse oximeter is used to measure the concentration of oxygen in the blood and to detect the pulse rate.

Question 7

Blood pressure cuffs are available in&#10;A)small.&#10;B)medium.&#10;C)large.&#10;D)All of the above are correct

Accepted Answer

Blood pressure cuffs are available in regular size, small size, and larger size to fit various arm sizes. It is important to select the correct size to ensure accurate blood pressure readings.

Question 8

A pulse oxymeter measures the oxygen saturation in the blood.

Accepted Answer

A pulse oxymeter is used to measure the concentration of oxygen in the blood.

Question 9

A rubber bulb attaches to the cuff with rubber tubing in which device?&#10;A)Capnograph&#10;B)Pulse oximeter&#10;C)Sphygmomanometer&#10;D)None of the above is correct.

Accepted Answer

A rubber bulb is not part of the either the capnograph or the pulse oximeter but is part of the sphygmomanometer.

Question 10

An aneroid dial system is part of which monitoring equipment?&#10;A)Sphygmomanometer&#10;B)Stethoscope&#10;C)EKG

Accepted Answer

A sphygmomanometer is an aneroid blood pressure cuff. It places pressure on the arteries to hear the systolic and diastolic blood pressure.

Question 11

Blood pressure readings should be&#10;A)taken prior to dental procedures being performed.&#10;B)at the completion of dental treatment.&#10;C)recorded in the patient's chart.&#10;D)Both A and C are correct.

Accepted Answer

The answer of Blood pressure readings should be&#10;A)taken prior to...
