Question 1

Absolute contraindications for conducting a cardiopulmonary exercise evaluation include which of the following?
1) Diastolic blood pressure greater than 110 mm Hg
2) Serious cardiac arrhythmias
3) Unstable angina
4) Recent myocardial infarction

Accepted Answer

Serious cardiac arrhythmias, unstable angina, and recent myocardial infarction are absolute contraindications for conducting a cardiopulmonary exercise evaluation due to the high risk of adverse events. Diastolic blood pressure greater than 110 mm Hg is not listed as an absolute contraindication in standard guidelines.

Question 2

To increase the likelihood that positive patient results are lasting, what must pulmonary rehabilitation programs provide?

Accepted Answer

Follow-up or reinforcement could be open-ended (available during regular rehabilitation sessions and offering open attendance) or could be scheduled weekly, monthly, bimonthly, or quarterly. The important thing is to have some type of follow-up available.

Question 3

Which of the following pulmonary function tests are most useful in determining whether a patient with restrictive lung disease should be considered for pulmonary rehabilitation? 1) DLCO 2) Total lung capacity (TLC) 3) FEV₁/FVC

Accepted Answer

DLCO and Total Lung Capacity (TLC) are most useful in determining the need for pulmonary rehabilitation in patients with restrictive lung disease. DLCO assesses the lung's capacity to transfer gas from air to the blood, important in restrictive diseases. TLC measures the maximum amount of air the lungs can hold, which is reduced in restrictive lung disease. FEV1/FVC ratio is more relevant in diagnosing and assessing obstructive lung diseases.

Question 4

Which of the following exercises are useful for reconditioning the lower extremities of patients undergoing pulmonary rehabilitation?
1) Walking on a flat surface for a specified period of time
2) Walking on a treadmill for a specified distance or time
3) Pedaling a stationary bicycle for a specified distance

Accepted Answer

All three exercises mentioned are beneficial for reconditioning the lower extremities in patients undergoing pulmonary rehabilitation. Walking on a flat surface, walking on a treadmill, and pedaling a stationary bicycle are all effective ways to improve lower limb strength and endurance, which are crucial for enhancing overall physical function in these patients.

Question 5

Which of the following exercises are useful for reconditioning the upper extremities of patients undergoing pulmonary rehabilitation?
1) Using a rowing machine
2) Using an arm ergometer
3) Pedaling a stationary bicycle
4) Using free hand weights

Accepted Answer

1, 2, and 4 are useful for reconditioning the upper extremities. A rowing machine and an arm ergometer specifically target the upper body, and free hand weights can be used for a variety of upper body exercises. Pedaling a stationary bicycle primarily targets the lower extremities.

Question 6

Which of the following measures during cardiopulmonary exercise evaluation are most useful in differentiating between exercise intolerance of cardiac versus ventilatory origin? 1) Maximum heart rate 2) O_2max 3) PaCO₂ 4) PaO₂

Accepted Answer

PaCO2 and PaO2 are arterial blood gases that help differentiate between cardiac and ventilatory causes of exercise intolerance. PaCO2 can indicate ventilatory efficiency, while PaO2 can reflect oxygenation issues.

Question 7

A patient in your pulmonary rehabilitation program has an orthopedic disability that precludes her from walking or using a stationary bicycle. Which of the following activities would you recommend to help recondition the lower extremities?

Accepted Answer

Patients with significant orthopedic disabilities can participate in aerobic aquatic exercises.

Question 8

Under which of the following conditions would you recommend ending a cardiopulmonary exercise evaluation? 1) Electrocardiogram indicating sinus tachycardia 2) 10% fall from baseline oxyhemoglobin (HbO₂) saturation 3) Fall in systolic blood pressure of more than 20 mm Hg 4) Request from the patient to terminate the test

Accepted Answer

2, 3, and 4 are valid reasons to consider ending a cardiopulmonary exercise evaluation. A 10% fall from baseline oxyhemoglobin saturation indicates significant oxygen desaturation, a fall in systolic blood pressure of more than 20 mm Hg can indicate cardiovascular instability, and a patient's request to terminate the test should always be respected for safety and ethical reasons. Sinus tachycardia, however, is a normal response to exercise and not typically a reason to end an evaluation.

Question 9

For which of the following patients would you recommend an open-ended format for a pulmonary rehabilitation program?
1) Those with scheduling difficulties
2) Those who require individual attention
3) Those who are self-directed

Accepted Answer

An open-ended format for a pulmonary rehabilitation program is beneficial for patients with scheduling difficulties (1), those who require individual attention (2), and those who are self-directed (3), as it allows for flexibility, personalized care, and autonomy in managing their rehabilitation process.

Question 10

What are some relative contraindications for cardiopulmonary exercise testing? 1) Severe pulmonary hypertension or cor pulmonale 2) Known electrolyte disturbances (e.g., hypokalemia) 3) SaO₂ or SpO₂ less than 85% breathing room air 4) Untreated or unstable asthma

Accepted Answer

1, 2, 3, and 4 are all relative contraindications for cardiopulmonary exercise testing. Severe pulmonary hypertension or cor pulmonale can worsen with the stress of exercise. Known electrolyte disturbances, such as hypokalemia, can predispose to arrhythmias during exercise. An oxygen saturation (SaO2 or SpO2) less than 85% indicates significant respiratory or cardiac impairment, increasing the risk during exercise. Untreated or unstable asthma can lead to bronchospasm and respiratory distress during the test.

Question 11

Which of the following should be monitored during a cardiopulmonary exercise evaluation? 1) Respiratory rate 2) HbO₂ saturation 3) ECG and blood pressure 4) FEV₁ and FVC

Accepted Answer

During a cardiopulmonary exercise evaluation, it is important to monitor respiratory rate, HbO2 saturation (oxygen saturation), and ECG and blood pressure to assess the patient's cardiovascular and respiratory response to exercise. FEV1 and FVC are pulmonary function tests that are not typically monitored in real-time during exercise.

Question 12

Below what level of the predicted FEV₁/FVC are patients with irreversible airway obstruction considered good candidates for pulmonary rehabilitation?

Accepted Answer

Patients in whom there is significant irreversible airway obstruction with a forced expiratory volume in 1 sec (FEV₁) of less than 2 L or an FEV₁% (FEV₁/FVC) of less than 60%.

Question 13

To maximize patient safety during cardiopulmonary stress testing, which of the following precautions would you recommend?
1) Immediate availability of a crash cart
2) Staff training in emergency life support
3) Presence of a physician throughout testing
4) Patient physical exam or ECG before testing

Accepted Answer

To maximize patient safety during cardiopulmonary stress testing, it is crucial to have immediate access to a crash cart for emergencies, ensure staff are trained in emergency life support to respond effectively to any situation, have a physician present throughout testing to make real-time decisions based on the patient's condition, and conduct a physical exam or ECG before testing to identify any pre-existing conditions that could pose a risk during the test.

Question 14

Which of the following patients with irreversible airway obstruction are the best candidates for pulmonary rehabilitation?

Accepted Answer

Patients in whom there is significant irreversible airway obstruction with an FEV₁ of less than 2 L or an FEV₁% (FEV₁/FVC) of less than 60%.

Question 15

The physical reconditioning component of a pulmonary rehabilitation program usually includes which of the following?
1) Aerobic exercises for the extremities
2) Timed walking exercise
3) Ventilatory muscle training

Accepted Answer

Physical reconditioning component of a pulmonary rehabilitation program includes all three options - aerobic exercises for the extremities, timed walking exercise, and ventilatory muscle training. These exercises aim to improve cardiovascular fitness, endurance, and strength of respiratory muscles, which help individuals with lung diseases to perform daily activities with ease and without undue shortness of breath.

Question 16

Which of the following patients are good candidates for pulmonary rehabilitation?
1) Unstable cardiovascular patients who require monitoring
2) Patients with exercise limitations due to severe dyspnea
3) Patients with malignant neoplasms involving the lungs

Accepted Answer

Pulmonary rehabilitation is most beneficial for patients who have chronic respiratory conditions and experience limitations in their daily activities due to symptoms like dyspnea (shortness of breath). It is not typically recommended for unstable cardiovascular patients due to the risks associated with exercise, nor is it generally recommended for patients with active malignant lung neoplasms, as the focus for these patients is usually on specific cancer treatment.

Question 17

While you are assisting in a treadmill cardiopulmonary stress test procedure, the patient complains to you of severe shortness of breath and some chest pain. Which of the following actions would you recommend at this time?

Accepted Answer

To guide practitioners in implementing exercise evaluation, the AARC has published Clinical Practice Guidelines: Exercise Testing for Evaluation of Hypoxemia and/or Desaturationand Pulmonary Rehabilitation.

Question 18

The O_2max at termination of exercise (as a percentage of the predicted) for five patients appears below. Which of these patients is the best candidate for pulmonary rehabilitation?

Accepted Answer

Patients in whom there is a respiratory limitation to exercise resulting in termination at a level less than 75% of the predicted maximum oxygen consumption (O_2max).

Question 19
