Answer to Question 1

ANS: A
Tenecteplase (TNKase) is given by bolus injection. Tissue plasminogen activator (tPA) must be infused over 90 minutes. Because tenecteplase (TNKase) is given by bolus injection, an infusion pump is not required. Although the patient should be monitored, tenecteplase (TNKase) does not require a prolonged infusion time.

Answer to Question 2

ANS: A
This patient shows signs of acute ST-elevation myocardial infarction (STEMI). Because cardiac troponin levels usually are not detectable until 2 to 4 hours after the onset of symptoms, treatment should begin as symptoms evolve. Chewable aspirin (ASA) should be given immediately to suppress platelet aggregation and produce an antithrombotic effect. Beta blockers are indicated but do not have to be given immediately. Ibuprofen is contraindicated. Morphine is indicated for pain management and should be administered after aspirin has been given.
