NR283 Exam 2 (week 3) Chamberlain
questions n answers rated A+
2025/2026
What is the role of alveoli and surfactant in respiration? - ANS ✔✔-alveoli: promotes the
diffusion of gases into the blood
-surfactant: lubricates and allows alveoli to POP back open
ventilation definition and assessment - ANS ✔✔-mechanical movement of air in and out of the
lungs
-assessment: ventilation rate, depth, quality
perfusion definition and assessment - ANS ✔✔-blood flow to the lungs
-assessment: CBC (complete blood count) and H&H (Hemoglobin & Hematocrit)
respiration - ANS ✔✔gas exchange
How is oxygen transported through the blood? - ANS ✔✔hemoglobin
Compliance - ANS ✔✔-Ability to expand
-move air in/out
-muscles, diaphragm, ribs
elasticity - ANS ✔✔-ability for lungs to return to relaxed state
-recoil
, -eg. emphysema: retaining CO2 which causes lungs to not fully relax
resistance - ANS ✔✔-anything blocking the airway
-eg. aspiration
-elderly and kids are most at risk
work of breathing - ANS ✔✔-energy expended to breathe
-eg. COPD, broken ribs, heart failure need lots of energy to breathe
s/s of respiratory system - ANS ✔✔-dyspnea
-cough
-sputum
-hemoptysis
-kussmaul respirations
-cheyne-stokes
dyspnea - ANS ✔✔difficulty breathing or shortness of breath
cough - ANS ✔✔dry or productive
sputum - ANS ✔✔-green, yellow, brown
-painful
hemoptysis - ANS ✔✔coughing up blood
Kussmaul respirations - ANS ✔✔-use of accessory muscles to breathe
