NUR 441 EXAM 1 QUICK STUDY GUIDE WITH
COMPLETE SOLUTION BASED ON FINAL EXAMS!!
Ventilation
answers: The process of moving gases into and out of the lungs
Perfusion
answers: The ability of the cardiovascular system to pump oxygenated blood to
the tissues and return deoxygenated blood to the lungs.
Newborn pulse
answers: 100-180
Newborn respirations
answers: 30-60
Adults pulse
answers: 60-100
Adults respirations
answers: 12-20
Postnatal Respiratory Changes
answers: 1. Compression of thorax during vaginal delivery forces out some of the
fetal lung fluid
2. Respirations are stimulated by hypoxemia, hypercarbia, cold, tactile stimulation,
and possibly by the plasma decrease of prostaglandin E2.
3. Inflation of normal lung is complete in a few breaths and most alveoli have
expanded in the first hour of life.
, 4. Surfactant in the lung liquid lowers surface tension and facilitates lung
expansion.
5. Pulmonary flow increases.
6. Closure of the foramen ovale and ductus arteriosus establishes the pulmonary
and circulatory system.
Peds differences in respiratory
answers: -Surfactant is lacking in premature infants, if born before 34 weeks they
have a higher risk of respiratory distress syndrome.
-Smaller airways and underdeveloped supporting cartilage predispose children to
increased risk of obstruction by mucus, edema, and foreign bodies.
-larynx is higher than it is in adults (c1-c4 range) therefore is closer to nasal
infections
-Lung size is proportional to body height
Cheyne strokes/near death breathing
answers: Ataxic meaning periods of apnes
Kussmauls
answers: Deep regular sighing with a fruit acetone breath
Respiratory acidosis 7.35
answers: .
Respiratory alkalsosis 7.45
