Q

Which of the following is not a proven therapeutic benefit of cardiac rehabilitation after a myocardial infarction (MI)?

A) Increased resting cardiac output
B) Decreased rate of recurrent MI
C) Improved left ventricular (LV) function
D) Decreased mortality

A

A) Increased resting cardiac output

Although cardiac rehabilitation increases maximum cardiac output, it does not increase resting cardiac output. Cardiac rehabilitation has been shown to reduce the rate of recurrent MI by 17%, decrease mortality secondary to MI by
15% to 20%, and increase LV ejection fraction after MI.

Q 
Which of the following is the medically acute inpatient cardiac rehabilitation phase?
A) Phase 1
B) Phase 2
C) Phase 3
D) Phase 4
A

A) Phase 1

is the first acute inpatient rehabilitation phase that can last from 1 to 14 days. The focus of this phase is to closely monitor the patient while increasing metabolic equivalents (MET) by 1 to 2 each day until a MET of 4 is reached. This should start on the acute care fl oor, usually in the CCU, and continue in acute rehabilitation. Cardiac patients should not wait to start therapy until they are on the rehabilitation floor. Phases are tailored to the individual. It is possible to skip Phase 1 in some patients and go directly to Phase 2 (intermediate outpatient phase after a noninvasive procedure).

Q

In which of the following diseases should target heart rate not be
used as a guide for exercise tolerance?

A) Heart transplant
B) Diabetes
C) Post–myocardial infarction
D) Gout

A

A) Patients with heart transplant

lack vagal innervation to
the heart, resulting in a higher baseline heart rate and slow return to baseline after exercise. Another cause of a baseline heart rate post transplant is antirejection medication.
Rate control is mediated mostly by hemodynamic changes and catecholamines

Q

How does the heart physiologically compensate for increased end-diastolic volume?

A) Increased peripheral resistance
B) Increased respiratory rate
C) Increased systolic contractility
D) Decreased systolic contractility

A

C) Increased systolic contractility

The Frank-Starling law is an important concept to understand in patients undergoing cardiac rehabilitation. The law states that when venous return and the end diastolic volume increase, the force generated by the myocardium increases resulting in a higher stroke volume. This law is particularly important in heart transplant patients, where the heart
compensates to change in demand primarily due to hemodynamic
changes and catecholamines rather than autonomic innervation.
In the case of increased afterload, the heart reduces stroke
volume to compensate. Recall here that cardiac output is the
product of stroke volume and heart rate

A) Phase 1
B) Phase 2
C) Phase 3
D) Phase 4

A

B) Phase 2

is a supervised ambulatory outpatient program lasting 3 to 6 months. An exercise tolerance test is usually performed at this phase to guide further rehabilitation. This is the immediate outpatient phase that requires a higher level of monitoring.

Q

Which of the following exercises are allowed during Phase 1 of cardiac rehabilitation?

A) Isometric exercises
B) Valsalva maneuvers
C) Raising legs above the heart
D) Dangle legs off bed

A

A) Isometric exercises

can raise the heart rate and demand on the heart. Although isometric exercises are initially held during cardiac rehabilitation, they are introduced later in short durations to condition the heart to handle increased demand. Valsalva maneuvers can cause arrhythmias and should be avoided in the acute phase of cardiac rehabilitation. Raising the legs above the heart can increase preload

Q

Which of the following exercise phases is important to prevent
syncope?

A) Aerobic phase
B) Anaerobic phase
C) Cool-down phase
D) Stretching phase

A

C) Cool-down phase

Patients undergoing cardiac rehabilitation are at
a higher risk for postexercise hypotension or even syncope if a slow cool down phase is not incorporated into the exercise regiment. The heart continues to generate a higher cardiac output based on the increased demand during the conditioning phase and an abrupt stop in exercise may result in a drop in blood pressure causing
hypotension.

Q

What is the target heart rate for a patient with stable arrhythmias during cardiac rehabilitation?

A) Maximum heart rate
B) Heart rate below the rate where arrhythmias
C) Heart rate 10 to 20 beats above the rate where arrhythmias are
noted
D) Patient is not a candidate for cardiac rehabilitation

A

B) Heart rate below the rate where arrhythmias

The goal of therapy for a patient with frequent stable arrhythmias is to condition the body to increase efficiency while maintaining the pulse under the heart rate where arrhythmias frequently occur.

Initial gains made during the first three rehabilitation phases may decrease with time if the patient does not continue with exercises to
maintain conditioning.

risk who have normal spirometry results; stage 1 (mild COPD) is
FEV1/FVC ratio < 70% predicted with FEV1 ≥ 80% predicted;
stage 2 (moderate COPD) is FEV1/FVC < 70% predicted and
FEV1 50% to 79% predicted; stage 3 (severe COPD) is
FEV1/FVC < 70% and FEV1 30% to 49% predicted; stage 4
(very severe COPD) is FEV1/FVC < 70% predicted and FEV1 <
30% predicted.
