Answer to Question 1

A
Methenamine should not be given to patients with renal impairment, because crystalluria can occur. There is no cross-reactivity between methenamine and antibiotic agents. Methenamine is safe for use during pregnancy. There is no organism drug resistance to methenamine.

Answer to Question 2

B
When alteplase is given within 2 hours after symptom onset, the death rate for MI has been shown to be 5.4, compared with 9.4 if given 4 to 6 hours after symptom onset. ASA may be given at the first sign of MI; it is not necessary to wait for cardiac enzyme results. Tenecteplase may be given more than 2 hours after onset of symptoms. Obtaining an order for an INR is not indicated.
