Read the first 6 Cardiopulmonary System flashcards as text

  1. Which of the following is an absolute contraindication to aerobic exercise?

    Answer: Unstable angina

    Unstable angina is an absolute contraindication to exercise because it signals impending myocardial infarction.

  2. Normal resting respiratory rate for an adult is:

    Answer: 12–20 breaths/min

    Normal adult resting respiratory rate is 12–20 breaths per minute.

  3. The 6-Minute Walk Test (6MWT) primarily measures:

    Answer: Functional exercise capacity and endurance

    The 6MWT measures the maximum distance a patient can walk in 6 minutes, reflecting submaximal functional exercise capacity.

  4. A patient with COPD demonstrates barrel chest. This is caused by:

    Answer: Air trapping from obstructed airways causing hyperinflation

    Chronic air trapping in COPD leads to pulmonary hyperinflation, pushing the diaphragm down and ribs outward, creating barrel chest.

  5. Which incentive spirometry technique encourages maximum inspiration?

    Answer: Sustained maximal inspiration (SMI)

    Incentive spirometry uses sustained maximal inspiration (SMI) to prevent atelectasis by maximally inflating the lungs.

  6. Which medication class used in cardiac patients can blunt the heart rate response to exercise?

    Answer: Beta-blockers

    Beta-blockers reduce heart rate response to exercise, requiring RPE-based rather than heart rate-based intensity monitoring.
