    B. sympathomimetic
  10. A direct-acting cholinergic agent often used in bronchial challenge tests to assess the degree of airway activity is:

    D. methocholine
  11. Which type of impulses travel from the brain to neuroeffector sites?

    A. efferent
  12. Epininephrine stimulates which of the following receptor sites?

    D. all of the above

    IV. propranolol

    C. I and II
  15. You are treating a patient for bronchospasm. Albuterol (an adrenergic bronchodilator) is the only aerosolized agent being administered at this time. What other type of aerosolized drug might you recomment?

    A. an anticholinergic bronchodilator
  16. You are treating an asthmatic who also happens to be taking propranolol (a beta blocker) for a history of cardiac arrhythmias. What effect would you expect albuterol to have on this patient?

    C. little or no effect
  17. In the parasympathetic branch of the nervous system, what name is given to the neurotransmitter that conducts nerve transmission at the ganglionic site?

    B. acetylcholine
  18. A parasympathetic effect is generally the same as a(n):

    A. muscarinic effect
  19. Cholinergic effect on *HEART RATE*
  20. Cholinergic effect on *BRONCHIAL SMOOTH MUSCLE*
  21. Cholinergic effect on *AIRWAY MUCOUS GLANDS*
    increase secretion
  22. Cholinergic effect on *SALIVARY GLANDS*
    increase secretion
  23. An agent causing stimulation of the parasympathetic nervous system:
  24. An agent blocking or inhibiting the effects of the parasympathetic nervous system:
  25. An agent causing stimulation of the sympathetic nervous system:
  26. An agent blocking or inhibiting the effect of the sympathetic nervous system:
  27. A drug causing stimulation of a receptor for acetylcholine:
  28. A drug blocking a receptor for acetylcholine:
  29. A drug stimulating a receptor for norepinephrine or epinephrine:
  30. T/F
    There is little or no direct sympathetic innervation of airway smooth muscle in the human lung.
  31. T/F
    The pulmonary circulation is innervated by both parasympathetic and sympathetic nerves.
  32. T/F
    There is evidence of a branch of nerves that are neither parasympathetic nor sympathetic and can cause relaxation of airway smooth muscle.
  33. T/F
    Muscarinic receptors are found in skeletal muscle.
  34. T/F
    Nicotine is capable of stimulating both sympathetic and parasympathetic autonomic cholinergic receptors.
