Answer to Question 1

A
Feedback:
Drugdrug interactions can occur with ketoconazole, diltiazem, verapamil, macrolide antibiotics, and HIV protease inhibitors; these combinations should be avoided because ranolazine levels may become extremely high. The nurse should get a complete list of current medications and consult with the health care provider regarding drug interactions before administering the medication as ordered. Nitroglycerin, propranolol, and diltiazem have no contraindication with medications used to treat HIV.

Answer to Question 2

A
Feedback:
Glucocorticoids block the actions of arachidonic acid, which leads to a decrease in the formation of prostaglandins and leukotrienes. They also impair the ability of phagocytes to leave the bloodstream and move to injured tissues; they inhibit the ability of lymphocytes to act within the immune system, including blocking the production of antibodies. Blocking arachidonic acid is, however, the initial action.
