Answer to Question 1

ANS: B
Sublingual (SL) medications are not subject to the first-pass effect of the liver. Oral (PO) nitroglycerin, on the other hand, undergoes rapid inactivation by hepatic enzymes.
SL nitroglycerin is directly absorbed into the bloodstream.
SL nitroglycerin is not 100 times higher than the PO dose; however, it is immediately available to the system, because it is not broken down by the liver.
SL nitroglycerin is not acid labile; it is not even exposed to the gut.

Answer to Question 2

ANS: A
Colesevelam can help control hyperglycemia in patients with diabetes, therefore hypoglycemia is a possible risk.
Hyperglycemia is not a risk for patients with diabetes who take colesevelam.
Insulin and colesevelam do not interact, therefore the insulin can be taken at the patient's preferred time or times.
Either insulin or oral antidiabetic agents can be taken with colesevelam.
