Answer to Question 1

D
Feedback:
Intrinsic factor, also secreted by the gastric mucosa, combines with dietary vitamin B12 so that the vitamin can be absorbed in the ileum, located in the small bowel. Other options are incorrect.

Answer to Question 2

Feedback:
Isoproterenol is a beta-specific adrenergic agonist used to prevent bronchospasm during anesthesia. Phenylephrine is an alpha-specific adrenergic agonist. Both dobutamine and ephedrine are alpha- and beta-adrenergic agonists.
