Answer to Question 1

C
Feedback:
When applied topically, nitroglycerin is absorbed directly into the systemic circulation. Absorption occurs at a slower rate and has a longer duration of action. The topical form is usually administered more frequently than one time per week. It is not more effective than the tablets. It does not have a faster action.

Answer to Question 2

B
Feedback:
In people who have demonstrated hypersensitivity to aspirin, all nonaspirin NSAIDs are contraindicated because cross-hypersensitivity reactions may occur with any drugs that inhibit prostaglandin synthesis. Acetaminophen (Tylenol) does not have cross-sensitivity with acetylsalicylic acid (aspirin) because it is not an NSAID. Morphine sulfate (MS Contin) does not have a cross-sensitivity to aspirin because it is an opioid, not an NSAID. Naloxone (Narcan) is an opioid antagonist and does not have cross-sensitivity with aspirin.
