Quiz 4 Questions Flashcards
A speech-language pathologist is working with a client who has chronic obstructive pulmonary disease (COPD). The client reports difficulty expelling air completely and experiences shortness of breath during speech. The pathologist aims to improve the client’s ability to control airflow and extend speech duration by focusing on the lung volume that remains in the lungs after normal expiration.
Which lung volume is the pathologist most likely focusing on?
a) Tidal volume
b) Inspiratory reserve volume
c) Residual volume
d) Functional residual capacity
d) Functional residual capacity
A professional athlete is undergoing respiratory training to improve breath control and endurance. During a session, the coach instructs the athlete to take the deepest breath possible, filling the lungs completely, and then to exhale as much air as possible. This exercise is designed to maximize lung function by utilizing multiple lung volumes.
Which lung volumes or capacities are primarily involved in this breathing exercise?
a) Only the expiratory reserve volume (ERV)
b) Only the inspiratory reserve volume (IRV)
c) The inspiratory reserve volume (IRV), tidal volume (TV), and expiratory reserve volume (ERV)
d) Both the inspiratory reserve volume (IRV) and the expiratory reserve volume (ERV)
c) The inspiratory reserve volume (IRV), tidal volume (TV), and expiratory reserve volume (ERV)
Which of the following statements about the location of abdominal muscles is false?
a) The internal oblique muscle is positioned between the external oblique and transversus abdominis muscles.
b) The transversus abdominis muscle is the deepest of the four abdominal muscles.
c) The rectus abdominis muscle is superficial to the external oblique muscle.
d) The external oblique muscle is superficial to the internal oblique muscle.
c) The rectus abdominis muscle is superficial to the external oblique muscle.
Which of the following statements about the diaphragm muscle is false?
a) The diaphragm is the primary muscle of inspiration, contracting to increase thoracic volume.
b) The diaphragm contracts and moves upward during inhalation, decreasing lung volume.
c) The central tendon of the diaphragm is a contractile structure that actively shortens during inspiration.
d) The diaphragm is innervated by the phrenic nerve, which originates from cervical spinal nerves C3–C5.
c) The central tendon of the diaphragm is a contractile structure that actively shortens during inspiration.
If a blockage were to occur in one of the bronchiole in the right lung, gas exchange in all the alveolar sacs would be restricted.
True or false?
False
The cervical vertebrae play a crucial role in respiration because they provide attachment points for the ribs and facilitate rib movement during breathing.
True or false?
False
A researcher is analyzing raw surface EMG signals from the masseter muscle during speech production. The recorded data shows both positive and negative voltage values in millivolts. The researcher concludes that this means some motor units are actively contracting while others are simultaneously inhibiting the muscle. Is this likely true or false?
True or false?
False
A yoga instructor is leading a class in deep belly breathing exercises. One student, curious about the role of different muscles, states that the rectus abdominis plays a crucial role in belly breathing by actively expanding the abdomen during inhalation. Is this likely true or false?
True or false?
False
