CCMA Practice Test

Most Missed CCMA Questions

These are the CCMA practice questions that people on Tigertest get wrong most often, from the answers of 10 people. Each one shows the share who missed it, the right answer and why.

   1. A clinic books three patients at the start of each hour and sees them in order of arrival. This scheduling method is called:

   • A.Cluster scheduling
   • B.Wave scheduling
   • C.Stream scheduling
   • D.Double booking

   Answer: B. Wave scheduling places several patients at the top of the hour and sees them as they arrive, absorbing late arrivals. Stream (time-specified) scheduling gives each patient a separate set time.

   2. A patient asks what makes the heart beat on its own. Which structure normally acts as the heart's natural pacemaker?

   • A.Atrioventricular (AV) node
   • B.Bundle of His
   • C.Purkinje fibers
   • D.Sinoatrial (SA) node

   Answer: D. The SA node in the right atrium starts each impulse, which travels to the AV node, the bundle of His, the bundle branches, and the Purkinje fibers. The AV node briefly delays the impulse but is not the normal pacemaker.

   3. Oxygen-poor blood returning from the body through the superior and inferior venae cavae first enters which heart chamber?

   • A.Right atrium
   • B.Left ventricle
   • C.Right ventricle
   • D.Left atrium

   Answer: A. Deoxygenated blood from the body enters the right atrium, passes through the tricuspid valve into the right ventricle, and is pumped through the pulmonary valve to the lungs. The left atrium receives oxygenated blood from the pulmonary veins.

4. 43% of people missed this (14 answers)

   4. A patient with emphysema has damage to the structures where oxygen and carbon dioxide are exchanged with the blood. These structures are the:

   • A.Trachea
   • B.Pleural membranes
   • C.Alveoli
   • D.Bronchi

   Answer: C. Alveoli are tiny air sacs surrounded by capillaries where oxygen enters the blood and carbon dioxide leaves it, and emphysema destroys their walls. The trachea and bronchi only conduct air, and the pleura lines the lungs and chest cavity.

5. 46% of people missed this (13 answers)

   5. Which part of the EKG waveform represents ventricular repolarization?

   • A.P wave
   • B.QRS complex
   • C.T wave
   • D.PR interval

   Answer: C. The T wave shows the ventricles recovering (repolarizing) before the next beat. The QRS complex is ventricular depolarization and the P wave is atrial depolarization.
