Nurs 2009 Exam 1 Questions With Complete Solutions
rhonchi
continuous low pitch during expiration
stridor
high pitch, upper airway constriction
pleural friction rub
grating/creaking sound, pleura of lungs is inflamed
cyanosis
bluish discoloration of skin and mucous membranes
hypoxia
oxygen deficiency in tissues
hypoxemia
Low oxygen levels in the blood.
transport of oxygen
oxygen sticks to hemoglobin in red blood cells. If the blood is
low or the hemoglobin is low, oxygen can't be carried well
helpful breathing position
high fowlers (sit patient up) 30 degrees
semi fowlers 45 degrees
oxygen promotion (medications)
bronchodilators, corticosteroids, mucolytics
, nasal cannula

4-12 L/min
NIPPV, BIPAP, CPAP
20-100 L/min
Normal PH
7.35-7.45
ABG
helps determine if a patient's blood pH is within the normal
range, normally drawn from the radial artery
EBP
a problem-solving approach to making clinically based
decisions, using the best evidence available
The need for EBP
