STEMI Question 1/9

1. For a suspected STEMI patient, what is the ideal timeline for performing an ECG and initiating reperfusion therapy (thrombolysis or PCI)?

ECG within 30 min, thrombolysis within 60 min

ECG within 10 min, thrombolysis within 30 min if PCI is unavailable

ECG within 20 min, thrombolysis within 90 min

ECG within 60 min, PCI within 120 min

STEMI Question 2/9

2. Which of the following statements about troponin in STEMI is most accurate?

Troponin must be elevated to confirm a STEMI before activating the cath lab

Troponin peaks immediately at the onset of chest pain

Troponin is elevated only in patients with complete occlusion of the LAD

Troponin I levels is not indicated in acute STEMI and you shouldn't wait troponin result to treat the patient

STEMI Question 3/9

ST elevation in leads II, III, aVF

ST depression in V2–V4

Peaked T waves without ST changes

Sinus tachycardia with normal intervals

Less than 10 minutes

Less than 15 minutes

Less than 20 minutes

Less than 30minutes

STEMI Question 5/9

60 minutes

90 minutes

30 minutes

45 minutes

STEMI Question 6/9

6. Which of the following is the most typical presenting symptom of a STEMI in the emergency department?

Right lower quadrant abdominal pain

Sudden onset of dizziness after standing up

Gradual, sharp chest pain worsened by deep inspiration

Sudden onset of central chest pressure radiating to the left arm

STEMI Question 7/9

7. Which of the following is the correct indication and dosage for thrombolytic therapy in STEMI?

STEMI diagnosed 24 hours ago, Alteplase 10 mg IV push only

STEMI within 12 hours, Tenecteplase (TNK) 0.5 mg/kg IV bolus

STEMI with unstable angina, Streptokinase 500,000 units IV

STEMI within 12 hours, Alteplase 15 mg IV bolus, then 50mg over 30 min then 35mg over 60 mins

STEMI Question 8/9

8. if the patient highly suspected to have STEMI (continuous chest pain , looks unwell or hemodynamically unstable) and 1st ECG unremarkable what you should do ?

send the patient for observation area and indorse the patient to my colleague

give the patient analgesia and discharge him home most likely muscular pain

give paracetamol , if ECG normal unlikely to be cardiac pain

keep patient under close monitor , do posterior and right side ECG , repeat ECG every 10 mins for the first 30 mins

STEMI Question 9/9
