Answer to Question 1

C
Feedback:
If a person has anoxia or hypoglycemia, the nerves might not be able to maintain the sodiumpotassium pump, and with continued lack of oxygen and/or glucose, the nerve cell will die. Other options are incorrect.

Answer to Question 2

B
Feedback:
Stimulation of muscarinic receptors increases gastrointestinal (GI) motility which would cause increased activity of bowel sounds. Other effects include pupil constriction, increased urinary bladder contraction, and a slowing of the heart rate. Stimulation of nicotinic receptors cause muscle contractions.
