NUR 134 Test 4 oxygenation/pain mgmt
QUESTIONS AND ANSWERS 100% RATED
CORRECT WITH 100% SURE
PASS|GRADED A+
ventilation - CORRECT ANSWERS "breathing"
inspiration (inhalation)
expiration (exhalation)
lung compliance - CORRECT ANSWERS degree of elasticity or expandability of lungs
airway resistance - CORRECT ANSWERS impedance of airflow through anatomical airways
accessory muscles - CORRECT ANSWERS muscles in abdomen, neck, and back are used to
facilitate and maintain respiratory movement when breathing is difficult
"retractions"
lung volume - CORRECT ANSWERS measured with pulmonary function tests, spirometry
pressures - CORRECT ANSWERS gases move into and out of lungs through pressure changes
diffusion - CORRECT ANSWERS movement of gas molecules from greater
pressure/concentration to lower pressure/concentration
depends on functioning alveolar system
,atelectasis - CORRECT ANSWERS collapse of alveoli prevents proper exchange of gases
surfactant reduces surface tension between alveoli to help prevent collapse
perfusion - CORRECT ANSWERS blood flow/delivery of oxygen to the lungs and body tissues
depends on properly functioning cardiovascular system
amount of blood flow through the lungs is a factor in amount of O2 and other gases exchanged
heart rate (HR) - CORRECT ANSWERS number of times the ventricles contract each minute
stroke volume (SV) - CORRECT ANSWERS amount of blood ejected from the Left ventricle
during each systole
cardiac output (CO) - CORRECT ANSWERS stroke volume (SV) X heart rate (HR)
volume of blood in Liters ejected by heart per minute
tachypnea - CORRECT ANSWERS increased respirations
> 20
bradypnea - CORRECT ANSWERS decreased respirations
< 12
, Kussmaul's respirations - CORRECT ANSWERS abnormally deep, very rapid sighing type of
respirations
ex. diabetic ketoacidosis
ataxic respirations - CORRECT ANSWERS uncoordinated respiratory patterns (no
coordination in rate or depth)
ex. stroke or trauma
Cheyne-Stokes respiration - CORRECT ANSWERS alternating periods of apnea and deep rapid
breathing
ex. heart failure
chest retraction - CORRECT ANSWERS visible sinking in soft tissues of chest between and
around firmer tissue and cartilaginous and bony ribs
sign of respiratory distress
paradoxical breathing - CORRECT ANSWERS asynchronous breathing (not simultaneous)
chest contraction during inspiration and expansion during expiration
increased anteroposterior diameter - CORRECT ANSWERS "barrel chest"
large and rounded thorax
