Giddens Concept 41 Test Bank
1. 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?
1. Bundle of His 2. Purkinje network 3. Intraarterial pathways 4. Sinoatrial
(SA) node 5. Atrioventricular (AV) node: 4, 3, 5, 1, 2
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 flow through these valves.
1. Mitral 2. Aortic 3. Tricuspid 4. Pulmonic: 3, 4, 1, 2
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?: Carries out gas exchange.
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.
4. A nurse auscultates heart sounds. When the nurse hears S2, which
valves is the nurse hearing close?: Aortic and pulmonic
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 first 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?: Diffusion
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?:
Respirations
7. The patient is breathing normally. Which process does the nurse
consider is working properly when the patient inspires?: Stimulation of
chemical receptors in the aorta
Inspiration is an active process, stimulated by chemical receptors in the aorta.
