Answer to Question 1

B
This patient is showing signs of heparin-induced thrombocytopenia, so the heparin should be discontinued immediately and the provider should be notified. The purplish color of the finger-tips is caused by thrombosis, not hypoxia, so oxygen is not indicated. This patient may need con-tinued anticoagulation therapy, so a request for protamine sulfate is not correct. Heparin is not a vitamin K inhibitor.

Answer to Question 2

D
The purpose of enteric coating is to prevent the acids of the stomach from destroying the medi-cation before it is effectively utilized by the body.
Sustained-release formulations allow medications to be released a little at a time throughout the day.
The first-pass effect is a process whereby a medication is broken down by the liver.
Excretion refers to the elimination of a medication's metabolic byproducts by the kidneys.
