45. (p. 241) When the patient has a left bundle branch block, the left conduction pathway is
blocked. The current travels down the left bundle branch to cause the left ventricle, the
septum, then the right ventricle to contract. FALSE
When the patient has a left bundle branch block, the left conduction pathway is blocked.
Current travels down the right bundle branch to cause the right ventricle, the septum, then
the left ventricle to contract.

Medium
Learning Outcome: Identify bundle branch block using the criteria for classification and explain how the rhythm occurs and may affect the
patient.
46. 241) When the patient has a right bundle branch block, the impulse will travel down
the conduction pathway normally until after the bundle of His. Since the right side is
blocked, the current must travel down the left bundle branch to activate the ventricles.
TRUE
When a patient has a right bundle branch block, the impulse will travel down the conduction
pathway normally until after the bundle of His. Since the right side of the conduction
pathway is blocked, current must travel down the left bundle branch to activate the
ventricles.

CHAPTER 12 Cardiac Stress Testing
1) What is the term for a procedure that does not require entrance
into a body cavity, tissue, or blood vessel?
A) Invasive procedure
B) Intensive procedure
C) Noninvasive procedure
D) Nuclear procedure
,Answer: C
Explanation: A noninvasive procedure does not require entrance into
a body cavity, tissue, or blood vessel.
2) Which of the following is not another name for exercise
electrocardiography?
A) Exercise tolerance test
B) Echocardiogram
C) Cardiac stress test
D) Treadmill stress test
Answer: B
Explanation: The exercise electrocardiograph is known by many
names, such as stress ECG, exercise tolerance test, cardiac stress test,
or exercise treadmill test. It is most commonly known as a treadmill
stress test because the exercise is usually performed on an exercise
treadmill.
3) Why might a physician order exercise electrocardiography for a
patient?
A) The patient has symptoms of cardiac problems that do not show
up on a resting ECG.
B) The patient has hypertension.
C) The patient has mitral valve prolapse.
D) The patient had an abnormal chest x-ray.
Answer: A
Explanation: Often a patient has symptoms of cardiac problems that
do not show up on a resting ECG. To determine the problems and
obtain an accurate diagnosis, the physician may order an exercise
electrocardiograph.
, 4) As an exercise stress test progresses, what happens to the level of
exertion of exercise?
A) It decreases in stages.
B) It is maintained throughout the test.
C) It increases in stages.
D) It is adjusted for patient comfort.
Answer: C
Explanation: During exercise electrocardiography, the level of
exertion of exercise is increased as the test progresses.
5) What is obtained near the end of each exercise stage?
A) Patient's temperature
B) Blood pressure reading and a 12-lead ECG
C) Assessment of patient's pain level
D) Blood for laboratory tests
Answer: B
Explanation: Toward the end of each exercise stage, a blood pressure
reading and a 12-lead ECG are obtained.
6) Which of the following is not assessed during exercise
electrocardiography?
A) Heart rate
B) Oxygen level
C) Physical appearance
D) Blood glucose level
Answer: D
