CPE Physiological Monitoring 2

Question 1

Which component of the pneumograph measures respiratory effort during a polygraph examination?

Accepted Answer

A convoluted rubber tube placed around the thorax or abdomen

Answer

A metal electrode attached to the fingertip

Answer

A cuff inflated around the upper arm

Answer

A piezoelectric sensor clipped to the earlobe

Question 2

In polygraph physiology, 'baseline' respiration is best described as:

Accepted Answer

The normal, undisturbed breathing pattern recorded before relevant questions begin

Answer

The fastest respiratory rate observed during questioning

Answer

The deepest breath the subject takes during the exam

Answer

Breathing recorded only during countermeasure detection phases

Question 3

A sudden increase in electrodermal activity (EDA) most directly indicates:

Accepted Answer

Activation of eccrine sweat glands controlled by the sympathetic nervous system

Answer

Increased parasympathetic nervous system activation

Answer

A decrease in blood pressure

Answer

Slower heart rate due to vagal tone

Question 4

What does a 'staircase' pattern in the cardio channel of a polygraph typically suggest?

Accepted Answer

Progressive rise in relative blood pressure over successive questions

Answer

Normal sinus rhythm with no deception indicators

Answer

A technical artifact from electrode movement

Answer

Parasympathetic suppression of heart rate

Question 5

During polygraph testing, 'apnea' in the pneumograph channel refers to:

Accepted Answer

A temporary cessation or suppression of breathing

Answer

An unusually deep inhalation followed by slow exhalation

Answer

Rapid shallow breathing exceeding 25 cycles per minute

Answer

A split-second spike in abdominal movement

Question 6

Which of the following best describes the 'galvanic skin response' (GSR) as measured in polygraph exams?

Accepted Answer

Changes in skin electrical conductance caused by sweat gland activity

Answer

Changes in skin temperature caused by blood vessel dilation

Answer

Muscle tension recorded from the surface of the forearm

Answer

Capillary refill time assessed at the fingertip

Question 7

The 'upper respiratory' pneumograph component is placed at which anatomical location?

Accepted Answer

Around the thoracic (chest) region

Answer

Around the lower abdomen just above the navel

Answer

Around the wrist to detect pulse

Answer

Around the thigh to measure leg movement
