Using the Henderson-Hasselbalch equation, determine the accuracy of the gas below. To be con-sidered accurate, it must be within 0.03 pH unit. pH = 7.22, PCO2 = 49 mm Hg, HCO3 = 20 mEq/L
 
  a. This gas is completely accurate.
  b. This gas is accurate as the calculated pH is 7.23.
  c. This gas is accurate as the calculated pH is 7.20.
  d. This gas is inaccurate according to the H-H equation.

Question 2

In acute respiratory acidosis, what would you expect the BE range to be?
 
  a. 4 to 6 mEq/L
  b. +2 to 2 mEq/L
  c. +4 to +6 mEq/L
  d. +22 to +26 mEq/L

Answer to Question 1

ANS: B
Plugging the ABG values supplied into the H-H equation results in a pH of 7.33 which indicate the gas is accurate as the value should be within 0.03 of the recorded pH.

Answer to Question 2

ANS: B
In cases of acute (uncompensated) respiratory acidosis, the BE commonly would be within the normal range, indicating correctly that the disturbance is purely respiratory in origin.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
