Answer to Question 1

ANS: C
Irritant receptors are responsible for laryngospasm, coughing, and slowing of the heartbeat. En-dotracheal intubation, airway suctioning, and bronchoscopy readily elicit vagovagal reflexes. Physical stimulation of the conducting airways, as with suctioning or bronchoscopy, may cause a severe case of bronchospasm, coughing, and laryngospasm.

Answer to Question 2

ANS: C
Such reflexes are responsible for laryngospasm, coughing, and slowing of the heartbeat. Endo-tracheal intubation, airway suctioning, and bronchoscopy readily elicit vagovagal reflexes. Phys-ical stimulation of the conducting airways, as with suctioning or bronchoscopy, may cause a se-vere case of bronchospasm, coughing, and laryngospasm.
