Answer to Question 1

B
Feedback:
These drugs are also contraindicated with any condition that could be exacerbated by blockade of the parasympathetic nervous system. These conditions include stenosing peptic ulcer, intestinal atony, paralytic ileus, gastrointestinal (GI) obstruction, severe ulcerative colitis, and toxic megacolon, all of which could be exacerbated with a further slowing of GI activity. Tachycardia, hypertension, and diabetes would not be contraindications to administration of glycopyrrolate.

Answer to Question 2

A
Feedback:
Respiration, or the act of breathing to allow gas exchange, is controlled by the central nervous system. The inspiratory musclesdiaphragm, external intercostal muscles, and abdominal musclesare stimulated to contract by the respiratory center in the medulla. The medulla receives input from chemoreceptors (neuroreceptors sensitive to carbon dioxide and acid levels) to increase the rate and/or depth of respiration to maintain homeostasis in the body.
