CCRP Exercise Testing 3

Question 1

Which exercise test protocol is most appropriate for elderly or severely deconditioned cardiac rehabilitation patients?

Accepted Answer

Naughton Protocol

Answer

Standard Bruce Protocol

Answer

Cornell Protocol

Answer

Ramp Protocol with 50-watt increments per minute

Question 2

What is the expected normal systolic blood pressure response during progressive treadmill exercise testing?

Accepted Answer

Increases progressively, typically by approximately 10 mmHg per MET

Answer

Remains constant at resting levels throughout exercise

Answer

Decreases by 5-10 mmHg with each stage

Answer

Fluctuates unpredictably between stages

Question 3

Exercise-induced ST elevation in leads WITHOUT pathological Q waves most likely indicates which condition?

Accepted Answer

Severe transmural ischemia or coronary artery spasm

Answer

Benign early repolarization pattern

Answer

Left ventricular hypertrophy strain pattern

Answer

Acute pericarditis

Question 4

What is the primary advantage of cardiopulmonary exercise testing (CPET) over conventional graded exercise testing (GXT)?

Accepted Answer

CPET provides direct measurement of VO2, ventilatory threshold, and respiratory gas exchange ratios

Answer

CPET is less expensive and more widely available in community settings

Answer

CPET eliminates the need for simultaneous ECG monitoring

Answer

CPET can be safely performed without physician supervision

Question 5

A 6-Minute Walk Test (6MWT) distance below what threshold is associated with poor prognosis in heart failure patients?

Accepted Answer

300 meters

Answer

600 meters

Answer

450 meters

Answer

150 meters

Question 6

Which medication class most significantly blunts the heart rate response during exercise testing and requires adjustment of target heart rate calculations?

Accepted Answer

Beta-blockers

Answer

ACE inhibitors

Answer

Dihydropyridine calcium channel blockers

Answer

HMG-CoA reductase inhibitors (statins)

Question 7

In cardiac rehabilitation, a heart rate recovery (HRR) of less than 12 bpm at 1 minute post-exercise is interpreted as which of the following?

Accepted Answer

Abnormal autonomic function associated with increased cardiovascular mortality risk

Answer

Evidence of excellent cardiovascular conditioning

Answer

Normal parasympathetic nervous system function

Answer

A successful training adaptation to cardiac rehabilitation
