Question 1 of 5
A woman was brought to the emergency department of a hospital after she fell into the ground and hurt her left leg. She is noted to be tachycardic and tachypneic. Painkillers were carried out to lessen her pain. Suddenly, she started complaining that she is still in pain and now experiencing muscle cramps, tingling, and paraesthesia. Measurement of arterial blood gas reveals pH 7.6, PaO2 120 mm Hg, PaCO2 31 mm Hg, and HCO3 25 mmol/L. What does this mean?
Correct Answer: B
Rationale: The arterial blood gas values indicate a pH of 7.6, suggesting alkalosis. The low PaCO2 at 31 mm Hg indicates hyperventilation, a respiratory process. The normal HCO3 suggests no metabolic involvement, and the lack of renal adjustment indicates an uncompensated state.
