LATEST PATHO 370 EXAM: A+ QUESTIONS AND ANSWERS
A disease that is native to a particular region is called
Endemic
The normal partial pressure of oxygen (PVO2) in venous blood is
40 mm Hg
Nearly all cardiac infarct is located in
Left Ventricle
The pH of a fluid reflects its degrees of ____________ (Select all that apply)
Acidity or Alkalinity
The pH can reflect pH found inside the cell or cerebrospinal fluid
FALSE! pH does not reflect
Which of the following is not a type of buffer?
Anything that's not
-Hemoglobin
-Protein
-Bicarbonate
-Phosphate
The most important buffer in extracellular fluid is
Bicarbonate
When there is insufficient carbonic acid, the respiratory system response is
Respiratory rate and depth decrease
Allows for temporary accumulation of carbonic acid (H2CO3)
Increased ventilation (hyperventilation) results in ; (Select all that apply)
Decreased carbon dioxide in the blood
Thus reducing carbonic acid
The lungs can excrete which of the followings acid/(s)
-ONLY Carbonic Acid (H2CO3)
Which is false about compensatory response of the respiratory system to an
imbalance of any metabolic acid?
Complete Compensation:
, The respiratory system can fully compensate for metabolic imbalances <----
FALSE
Does not correct a pH disorder
Does compensate for it by adjusting the pH back toward normal
Other blood chemistry values are made abnormal in the process.
Deficit of any acid except carbonic acid is hypoventilation
Excess of any acid except carbonic acid is hyperventilation
For an imbalance of metabolic acid
•Begins in minutes
•Requires at least several hours for full effectiveness
About Renal Contribution of the acid-bases imbalance, if a metabolic acid is
deficient in blood, which one is false?
-Increase the reabsorption of hydrogen ions (H+)<----FALSE
About Renal Contribution of the acid-bases imbalance, Which is false about the
decreased HCO3-(bicarbonate)
-Kidneys would decrease the excretion of bicarbonate <----FALSE
In clinical manifestation of severe metabolic acidosis, Which one is false? (Select
all that apply?
Anything that's not:
-Headache
-Confusion
-Kussmaul Respirations
In relation to in compensated metabolic acidosis of arterial blood gases, Which
one is false?
-Increased oxygen saturation(O2Sat) <----FALSE
or anything thats not:
-Decreased Bicarbonate (HCO)
-Decreased Partial Pressure of Co2 (PaCo2)
-Normal pH
Which of the following is NOT a cause of respiratory acidosis by Inadequate
neuromuscular function?
