A patient's assessment data present as follows: pH, 7.10; PaCO2, 60 mm Hg; PaO2, 40 mm Hg; HCO3, 24 mEq/L; RR, 34 breaths/min; HR, 128 beats/min; and BP, 180/92 mm Hg.
 
  This condition is best described as
 
  a. uncompensated respiratory acidosis.
  b. uncompensated metabolic acidosis.
  c. compensated metabolic acidosis.
  d. compensated respiratory acidosis.

Question 2

Which of the following criteria are representative of the patient in normal sinus rhythm?
 
  a. Heart rate, 64 beats/min; rhythm regular; PR interval, 0.10 second; QRS, 0.04 second
  b. Heart rate, 88 beats/min; rhythm regular; PR interval, 0.18 second; QRS, 0.06 second
  c. Heart rate, 54 beats/min; rhythm regular; PR interval, 0.16 second; QRS, 0.08 second
  d. Heart rate, 92 beats/min; rhythm irregular; PR interval, 0.16 second; QRS, 0.04 second

Answer to Question 1

A
The pH is below normal range (7.35-7.45), so this is uncompensated acidosis. The PaCO2 is markedly elevated, and the HCO3 is normal. This indicates uncompensated respiratory acidosis. Uncompensated respiratory acidosis values include a pH below 7.35, PACO2 above 45 mm Hg, and HCO3 of 22 to 26 mEq/L. Uncompensated metabolic acidosis values include a pH below 7.35, PACO2 of 35 to 45 mm Hg, and HCO3 above 22 mEq/L. Compensated metabolic acidosis values include a pH of 7.35 to 7.39, PACO2 below 35 mm Hg, and HCO3- below 22 mEq/L. Compensated respiratory acidosis values include a pH of 7.35 to 7.35, PACO2 above 45 mm Hg, and HCO3 above 26 mEq/L.

Answer to Question 2

B
The parameters for normal sinus rhythm are heart rate, 60 to 100 beats/min; rhythm, regular; PR interval, 0.12 to 0.20 second; and QRS, 0.06 to 0.10 second.
