graded A+
• A nurse is teaching staff about the conduction of the heart. In which order
will the nurse present the conduction cycle, starting with the first structure?
• Bundle of His
• Purkinje network
• Intraatrial pathways
• Sinoatrial (SA) node
• Atrioventricular (AV) node
• 5, 4, 3, 2, 1
• 4, 3, 5, 1, 2
• 4, 5, 3, 1, 2
• 5, 3, 4, 2, 1
ANS: B
The conduction system originates with the SA node, the “pacemaker” of the
heart. The electrical impulses are transmitted through the atria along
intraatrial pathways to the AV node. It assists atrial emptying by delaying
the impulse before transmitting it through the Bundle of His and the
ventricular Purkinje network.
• A nurse is teaching the patient with mitral valve problems about the valves
in the heart. Starting on the right side of the heart, describe the sequence of
the blood flow through these valves.
• Mitral
• Aortic
• Tricuspid
, • Pulmonic
• 1, 3, 2, 4
• 4, 3, 2, 1
• 3, 4, 1, 2
• 2, 4, 1, 3
ANS: C
The blood flows through the valves in the following direction: tricuspid,
pulmonic, mitral, and aortic.
• A nurse explains the function of the alveoli to a patient with respiratory
problems. Which information about the alveoli’s function will the nurse
share with the patient?
• Carries out gas exchange
• Regulates tidal volume
• Produces hemoglobin
• Stores oxygen
ANS: A
The alveolus is a capillary membrane that allows gas exchange of
oxygen and carbon dioxide during respiration. The alveoli do not
store oxygen, regulate tidal volume, or produce hemoglobin.
• A nurse auscultates heart sounds. When the nurse hears S2, which
valves is the nurse hearing close?
• Aortic and mitral
• Mitral and tricuspid
• Aortic and pulmonic
• Mitral and pulmonic
ANS: C
