Respiratory alkalosis

Respiratory acidosis

Metabolic acidosis

Answer and Explanation

The Correct Answer is C

A. Metabolic alkalosis is characterized by a high pH and a high HCO3- level; this does not match the provided values.

B. Metabolic acidosis would show a low pH and a low HCO3-, which does not match the findings.

C. The pH is high (7.45) while the Paco2 is low (30 mm Hg), indicating respiratory alkalosis. The low HCO3- could be a compensatory mechanism but does not change the primary interpretation of respiratory alkalosis.

D. Respiratory acidosis would be indicated by a low pH and a high Paco2, which is not the case here.

B. Asystole: Asystole is characterized by a flat line, indicating no electrical activity, which is not present in this strip.

C. Normal sinus rhythm: Normal sinus rhythm would show identifiable P waves, a normal QRS complex, and a regular rate, which are not observed here.

D. Ventricular fibrillation: Ventricular fibrillation appears as chaotic, irregular waveforms with no clear QRS complexes or organization, which does not match the rhythm shown.
