QuestionSBA
QuestionChoice
Given this patient's past medical history and symptoms, he is likely experiencing a panic attack which would lead to hyperventilation. This would result in him exhaling excessive CO~2~, thus causing decreased CO~2~, which would cause his pH to increase into an alkalosis. This would be seen via a raised pH and decreased PaCO~2~.

a
Respiratory alkalosis
QuestionChoice
Given this patient's past medical history and symptoms, it is unlikely that the cause of his symptoms is metabolic. Instead, he is most likely to be experiencing a panic attack which is causing hyperventilation and leading to exhalation of excessive CO~2~. This decreased CO~2~ would push his pH to increase into an alkalosis, not an acidosis, giving him a respiratory alkalosis overall.

b
Metabolic acidosis
QuestionChoice
Given this patient's past medical history and symptoms, it is likely that the cause of his symptoms is respiratory - specifically a panic attack causing hyperventilation and leading to exhalation of excessive CO~2~. However, this decreased CO~2~ would push his pH to increase into an alkalosis, not an acidosis, giving him a respiratory alkalosis overall.

c
Respiratory acidosis
QuestionChoice
Given this patient's past medical history and symptoms, it is unlikely that the cause of his symptoms is metabolic. Instead, he is most likely to be experiencing a panic attack which is causing hyperventilation and leading to exhalation of excessive CO~2~. This decreased CO~2~ would push his pH to increase into an alkalosis, giving him a respiratory alkalosis overall.

e
Mixed respiratory and metabolic alkalosis
QuestionChoice
Given this patient's past medical history and symptoms, it is unlikely that the cause of his symptoms is metabolic. Instead, he is most likely to be experiencing a panic attack which is causing hyperventilation and leading to exhalation of excessive CO~2~. This decreased CO~2~ would push his pH to increase into an alkalosis, giving him a respiratory alkalosis overall.

A 20-year-old male with a known anxiety disorder presents with shortness of breath and the feeling of pins and needles in his fingers. A venous blood gas (VBG) is carried out.

Given his likely diagnosis, what is the VBG most likely to show?
