A. Instruct the client to maintain a breathing rate no less than twice the normal rate: This does not correct the underlying issue of hyperventilation and may worsen symptoms.
B. Have the client tuck her chin to her chest: This does not address the symptoms of hyperventilation.
C. Administer oxygen via nasal cannula: Unnecessary, as the issue is not hypoxia but respiratory alkalosis from excessive exhalation of CO₂.
