and Verified Questions |100% Verified||Newest Exam!!!
What values indicate hypoxemia? - Answer-- PaO2 of less
than 70
- SaO2 of less than 92%
What value indicates excessive oxygen therapy? -
Answer-PaO2 greater than 100
What is compensation? - Answer-The body tries to return
pH to normal when CO2 or HCO3 levels cause an
imbalance
What lab value shows full compensation? - Answer-A
normal pH
What indicates partial compensation? - Answer-When the
pH is not fully normalized
,2|Page
How do we decide what type of imbalance it is if the body
is fully compensated? - Answer-Decide if the pH value is
closer to the acidotic or alkalotic value
Causes, assessment, and treatment of respiratory
acidosis - Answer-- caused by retaining CO2 from
hypoventilation
- presents as a headache, tachycardia, confusion, or
restlessness
- treated by improving ventilation
How does the body compensate for respiratory acidosis? -
Answer-The kidneys work slowly to retain HCO3
Causes, assessment, and treatment of respiratory
alkalosis - Answer-- caused by blowing off too much CO2
during hyperventilation
- presents as headache, tachycardia, confusion, or
restlessness
- treated by decreasing tidal volume, relieving anxiety,
controlling pain, and correcting hypoxia
,3|Page
How does the body compensate for respiratory alkalosis?
- Answer-The kidneys work slowly to excrete HCO3
Causes, assessment, and treatment of metabolic acidosis
- Answer-- caused by abnormal metabolism, increased
acid retention, and decreased HCO3
- presents as Kussmaul respirations, tachycardia,
headache, weakness, nausea/vomiting, or abdominal pain
- treated by correcting renal failure, HCO3 replacement,
control diarrhea, and improving perfusion
How does the body compensate for metabolic acidosis? -
Answer-The lungs work quickly to blow of excess CO2
with hyperventilation
Causes, assessment, and treatment of metabolic alkalosis
- Answer-- caused by losing acid by vomiting or NG
suction, K+ or Cl- loss resulting in retaining bases, and
increased HCO3
- presents as confusion, muscle cramps, or shallow
respirations
- treated by restoring fluids and electrolytes and limiting
alkaline intake
, 4|Page
How does the body compensate for metabolic alkalosis? -
Answer-The lungs work to hold onto CO2 by causing
hypoventilation
What are the consequences of a low pH? - Answer-
Cardiac contractions decrease and so does the vascular
response to catecholamines and drugs in the body
What are the consequences of a high pH? - Answer-
Impairs the oxygenation of tissues and neuromuscular
function
What conditions cause respiratory alkalosis? - Answer--
anxiety attacks
- use of stimulants
- high levels of pain
- iatrogenic causes
- hypoxemia
- fever
- sepsis
- salicylate poisoning
