Paramedics Exam Medical Emergencies 2

Question 1

A 58-year-old male presents with crushing chest pain radiating to the jaw, diaphoresis, and nausea. His 12-lead ECG shows ST elevation in leads II, III, and aVF. Which coronary artery is most likely occluded?

Accepted Answer

Right coronary artery

Answer

ST elevation in leads II, III, and aVF indicates an inferior STEMI, most commonly caused by right coronary artery (RCA) occlusion.

Question 2

A patient with known COPD presents in severe respiratory distress. SpO2 is 84% on room air. What is the appropriate oxygen delivery target for this patient?

Accepted Answer

88-92% SpO2

Answer

COPD patients may rely on hypoxic drive, so target SpO2 of 88-92% to avoid suppressing respiratory effort while correcting dangerous hypoxia.

Question 3

A 70-year-old female presents with sudden onset of right-sided facial droop, right arm weakness, and aphasia. These symptoms began 45 minutes ago. Which intervention is the highest priority?

Accepted Answer

Establish IV access and draw blood glucose

Answer

Checking blood glucose is critical because hypoglycemia can mimic stroke symptoms, and IV access is needed for potential thrombolytic therapy at the hospital.

Question 4

A 35-year-old patient presents with severe anxiety, carpopedal spasm, perioral tingling, and rapid deep breathing. Vital signs: RR 28, SpO2 99%, BP 130/80. What is the most likely diagnosis?

Accepted Answer

Hyperventilation syndrome

Answer

Carpopedal spasm and perioral tingling with rapid breathing and normal SpO2 indicate hyperventilation syndrome causing hypocapnia and respiratory alkalosis.

Question 5

Which finding on a 12-lead ECG is most consistent with right ventricular infarction complicating an inferior STEMI?

Accepted Answer

ST elevation in leads V4R and V5R

Answer

Right-sided precordial leads V4R and V5R showing ST elevation indicate right ventricular infarction, which commonly complicates inferior STEMI.
