Part of the Cardiology and Resuscitation practice questions exam area.
This page holds 336 free practice questions for Chapter 18, Cardiovascular Emergencies, covering ECG and 12-lead interpretation, acute coronary syndrome, heart failure, cardiac arrest, electrical therapy, and vascular emergencies. They are written for paramedic and EMT students working through Nancy Caroline's Emergency Care in the Streets, 9th edition. Every question shows the correct answer with a short explanation as soon as you tap, so you learn while you test rather than waiting until the end.
Study it two ways: the 10 Question Blitz, a quick round where every right answer lights a siren and any misses lead into Lights & Sirens, a 5-in-a-row drill on that section, or the full 100-question test drawn at random from the whole chapter. After each test you get a score and a section-by-section breakdown. Progress on the full test is saved on your device, so you can stop and pick up later.
In most patients, which coronary artery supplies the sinoatrial (SA) and atrioventricular (AV) nodes?
Answer: B. Right coronary artery
In most people the right coronary artery supplies the SA node and the AV node. This is why inferior MIs from RCA occlusion often produce bradycardia and AV blocks.
While assessing a patient with chest pain using OPQRST, which question best addresses the 'Q'?
Answer: D. What does the pain feel like?
Q stands for quality: asking the patient to describe the pain (pressure, sharp, tearing, burning). Onset, radiation, and provocation are other OPQRST elements.
At the standard paper speed of 25 mm/sec, each small box on the ECG represents:
Answer: A. 0.04 seconds
At 25 mm/sec each 1-mm small box is 0.04 seconds, and each large box (5 small boxes) is 0.20 seconds.
Most students use the 10 Question Blitz for daily practice and take the full 100-question test in the days before a class exam or NREMT practice. Lights & Sirens after a blitz is the fastest way to close gaps the night before a test.
Every question in this chapter is also listed by section, with answers, on the topic pages above. See all paramedic topics or take the NREMT paramedic practice test.
