MULTIPLE CHOICE
1. A nurse is teaching sta᯿అ about the conduction of the heart. In which order will the nurse present the conduction cycle,
starting with the ᯿贄 rst structure?
1. Bundle of His
2. Purkinje network
3. Intraatrial pathways
4. Sinoatrial (SA) node
5. Atrioventricular (AV) node
a. 5, 4, 3, 2, 1
b. 4, 3, 5, 1, 2
c. 4, 5, 3, 1, 2
d. 5, 3, 4, 2, 1

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.

2. 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 ᯿贄 ow through these valves.
1. Mitral
2. Aortic
3. Tricuspid4. Pulmonic
a. 1, 3, 2, 4
b. 4, 3, 2, 1
c. 3, 4, 1, 2
d. 2, 4, 1, 3
ANS: C
The blood ᯿贄 ows through the valves in the following direction: tricuspid, pulmonic, mitral, and aortic.

3. 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?
http://boostgrade.info/chapter41oxygenation/ 2/34
,10/15/2016 Chapter 41: Oxygenation | Nursing Test Banks
a. Carries out gas exchange
b. Regulates tidal volume
c. Produces hemoglobin
d. 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.
DIF:Understand (comprehension)REF:872-873
OBJ: Describe the physiological processes of ventilation, perfusion, and exchange of respiratory gases. TOP: Teaching/Learning
MSC: Physiological Adaptation
4. A nurse auscultates heart sounds. When the nurse hears S2, which valves is the nurse hearing close?
a. Aortic and mitral
b. Mitral and tricuspid
c. Aortic and pulmonic
d. Mitral and pulmonic
ANS: C
As the ventricles empty, the ventricular pressures decrease, allowing closure of the aortic and pulmonic valves, producing the
second heart sound, S2. The mitral and tricuspid produce the ᯿贄 rst heart sound, S1. The aortic and mitral do not close at the
same time. The mitral and pulmonic do not close at the same time.

5. The nurse is teaching about the process of exchanging gases through the alveolar capillary membrane. Which term will the
nurse use to describe this process?
a. Ventilation
b. Surfactant
c. Perfusion
d. Di᯿అ usion
ANS: D
Di᯿అ usion is the process of gases exchanging across the alveoli and capillaries of body tissues. Ventilation is the process of
moving gases into and out of the lungs. Surfactant is a chemical produced in the lungs to maintain the surface tension of the
alveoli and keep them from collapsing. Perfusion is the ability of the cardiovascular system to carry oxygenated blood to tissues
and return deoxygenated blood to the heart.

6. A nurse is caring for a patient who was in a motor vehicle accident that resulted in cervical trauma to C4. Which assessment is
the priority?
a. Pulse
b. Respirations
c. Temperature
d. Blood pressure
