A hospital patient's arterial blood gases indicate normal levels of oxygen and increased carbon dioxide. The patient's respiratory rate is 12 breaths/minute (normal 14 to 20 breaths/minute) with all other vital signs within normal range
While not evident from assessment and diagnostics, the patient's kidneys are minimizing both H+ excretion and HCO3- reabsorption. What is this client's most likely diagnosis?
A)
Respiratory alkalosis
B)
Metabolic acidosis
C)
Respiratory acidosis
D)
Metabolic alkalosis
Ans:
D
Feedback:
In response to increased bicarbonate, the client is hypoventilating to increase carbon dioxide partial pressure. As well, renal compensation is aimed at lowering pH by both reducing H+ excretion and HCO3- reabsorption. The given data are incongruent with the other major acid-base imbalances.
