NR 341 Quiz #1 ABGs questions with correct answers
Why is an ABG analysis usually ordered? Correct Answer-An ABG
analysis is usually one of the first tests ordered to assess respiratory
status because it helps evaluate gas exchange in the lungs.
What measures are included in an ABG analysis? Correct Answer--pH
-Partial pressure of arterial carbon dioxide
-Partial pressure of arterial oxygen
-Bicarbonate level
What does pH show in an ABG analysis? Correct Answer-pH is an
indication of hydrogen ion concentration in the blood and shows the
blood's alkalinity or acidity.
What does the partial pressure of arterial carbon dioxide reflect in an
ABG analysis? Correct Answer-Known as the respiratory parameter,
PaCO2 reflects the adequacy of the lungs' ventilation and CO2
elimination.
What does the partial pressure of arterial oxygen reflect in an ABG
analysis? Correct Answer-The PaO2 reflects the body's ability to pick up
O2 from the lungs
What does thee bicarbonate level reflect in an ABG analysis? Correct
Answer-Known as the metabolic parameter, the HCO3- level reflects the
kidney's ability to retain and excrete HCO3-
, What are the normal ABG values? Correct Answer--pH: 7.35-7.45
-PaCO2: 35-45 mmHg
-HCO3-: 22-26 mEq/L
-PaO2: 80-100 mmHg
What lab levels characterize respiratory acidosis? Correct Answer-pH <
7.35; PaCO2 > 45
What causes respiratory acidosis? Correct Answer-Hypoventilation
(CNS depression, pulmonary edema)
Chronic obstructive pulmonary disease (COPD), sedative overdose,
severe pneumonia, atelectasis, respiratory muscle weakness
What are the assessment findings that accompany respiratory acidosis?
Correct Answer-Bradycardia, hypotension, confusion
Lethargy, dizziness, headache, coma, warm/flushed skin, seizures,
dysrhythmias (related to potassium shifts during compensation)
What are the treatments for respiratory acidosis? Correct Answer-
Increase RR, reposition patient, maintain patent airway
What lab values characterize respiratory alkalosis? Correct Answer-pH
> 7.45; PaCO2 < 35
