ATI Med Surg Exam 10 Questions

Extract:


Question 1 of 5

George Kent is a 54-year-old widower with a history of chronic obstructive pulmonary disease and was rushed to the emergency department with increasing shortness of breath, pyrexia, and a productive cough with yellow-green sputum. He has difficulty communicating because of his inability to complete a sentence. Upon examination, crackles and wheezes can be heard in the lower lobes; he has tachycardia and a bounding pulse. Measurement of arterial blood gas shows pH 7.3, PaCO2 68 mm Hg, HCO3 28 mmol/L and PaO2 60 mm Hg. How would you interpret this?

Correct Answer: C

Rationale: The low pH (acidosis) and high PaCO2 indicate respiratory acidosis. The increased HCO3 suggests a renal compensatory mechanism attempting to normalize the pH.
