Parasympatholytics

What is the primary function of parasympatholytics?

• To stimulate bronchoconstriction

• To enhance the release of chemicals that cause inflammation

• To block the action of ACH and stop bronchoconstriction

• To increase mucous production

How do parasympatholytics work in relation to bronchoconstriction?

• They increase the efficiency of the reflex arc

• They stimulate the release of ACH

• They directly stimulate the irritant receptors in the airways

• They block ACH from stimulating cells, thus stopping bronchoconstriction

Which of the following is NOT an adverse side effect of parasympatholytics according to the text?

• Tachycardia

• Dry Mouth

• Increased secretions

• Dilated pupils

Where do parasympatholytics work most effectively?

• In the larger airways

• In the smaller airways

• At the neuroeffector sites in the brain

• At the afferent nerve fibers of the vagus nerve

What allows the electrical impulse to jump from the afferent to the efferent nerve fibers in the process of bronchoconstriction?

• The stimulation of irritant receptors

• The reflex arc

• The release of ACH

• The direct stimulation of mucous glands

What is the result of the electrical message traveling down the efferent nerve fibers in the process of bronchoconstriction?

• Decreased mucous production

• Stimulation of the brain's response center

• Release of ACH at the neuroeffector sites causing bronchoconstriction and inflammation

• Immediate relief of symptoms

Why are parasympatholytics considered safe to use with adrenergics?

• Because they both cause bronchoconstriction

• Because they work on two different pathways

• Because they stimulate different receptors

• Because they both decrease mucous production
