(Latest Update 2024/2025) Solutions
what conditions alter gas exchange - CORRECT ANSWERS (the mighty 4)
hypoxemia, hypoxia, hypercarbia, hypocarbia
ventilation - CORRECT ANSWERS movement of air into and out of lungs
through the act of
respiration - CORRECT ANSWERS exchange of the gases oxygen and carbon
dioxide in the lungs
what affects pulmonary function? - CORRECT ANSWERS upper respiratory
infections (URIs) cold, rhinosinusitis, pharyngitis, influenza, lower respiratory
infections, RSV, acute bronchitis, tuberulosis
what affects ventilation? - CORRECT ANSWERS rate/depth of respirations,
lung compliance and elasticity and airway resistance
hyperventilation - CORRECT ANSWERS occurs when a person breathes fast
and deeply to move large amount of air through the lungs, causing too much carbon
dioxide to be removed by the alveoli.
hypoxemia - CORRECT ANSWERS low arterial blood oxygen levels
hypoxia - CORRECT ANSWERS inadequate oxygenation of organs and
tissues / hypoxic central nervous system causes abnormal brain functioning /
hypoxic renal issues causes abnormal kidney functioning (poor urine outpout)
hypoxic limb tissue results in muscle functioning (muscle weakness and pain with
exercise)
hypercarbia (hypercapnia) - CORRECT ANSWERS an excess of dissolved CO2
in the blood
hypocarbia (hypocapnia) - CORRECT ANSWERS low level of dissolved CO2 in
the blood

bradycardia (slow heart rate), hypotension (low blood pressure), stupor
(unconsciousness) cardiac dysrhythmias irregular heartbeat)
oxygen delivery systems - CORRECT ANSWERS nasal cannula, simple mask,
non-breather, venuri mask, face tent
the rights of medication - CORRECT ANSWERS Right medication
