Questions

Show up ready on day 1 with a complete understanding of the core topics needed for a successful journey through PA school. Patient care begins with knowledge, and knowledge begins with the fundamentals. The Pre-PA Prep Qbank Bundle covers these fundamentals with anatomy, physiology, medical terminology, PA professional practice, and wellness.

Each question is written to resemble the format and topics on the exam, meaning you won’t see any negatively phrased questions, no “all of the following except,” no “A and B”…you know what we mean. Most importantly, all questions include selective distractors (incorrect answer choices), which will help you think critically.

  • Must address important content
  • Must be well structured

Question

During which phases of the cardiac cycle are all the valves closed?
A Atrial systole and isovolumetric ventricular contraction
B Isovolumetric ventricular contraction and isovolumetric ventricular relaxation
C Rapid ventricular filling and reduced ventricular filling
D Reduced ventricular ejection and isovolumetric ventricular relaxation
Correct Answer Distractors
The cardiac cycle consists of seven phases that lead to blood being circulated throughout the body. The phases of the cardiac cycle are atrial systole, isovolumetric ventricular contraction, rapid ventricular ejection, reduced ventricular ejection, isovolumetric ventricular relaxation, rapid ventricular filling, and reduced ventricular filling. The isovolumetric ventricular contraction phase is marked by an increase in ventricular pressure as the ventricles contract. This phase begins when the atrioventricular (tricuspid and mitral) valves close due to the pressure in the ventricles exceeding the pressure in the atria. The volume of the blood in the ventricles remains constant during isovolumetric ventricular contraction because the atrioventricular and semilunar valves (aortic and pulmonic) are closed. Isovolumetric ventricular relaxation occurs between ventricular ejection of blood and ventricular filling. It begins when the semilunar valves close following ventricular contraction and ends with the opening of the atrioventricular valves. The volume of blood in the ventricles remains constant because each of the valves is closed, and the pressure decreases because the ventricles are relaxed.

Explanations

Written with a purpose

Understanding why an answer choice is incorrect is just as important as knowing why one is correct. That’s why every Rosh Review question includes detailed explanations for the correct and incorrect answer choices. These comprehensive summaries link the most important components of a topic—from risk factors to diagnostics and treatment—giving you the context to build relationships between them.
