What action should a nurse take if a laboring client using accelerated-blow breathing complains of tingling fingers and dizziness?

The appropriate action for a nurse to take when a laboring client using accelerated-blow breathing experiences tingling fingers and dizziness is to have the client breathe into her cupped hands. This technique is helpful in addressing symptoms typical of hyperventilation, which can occur due to the rapid, shallow breathing associated with this type of breathing pattern.

Breathing into cupped hands aids in re-establishing a balance of carbon dioxide in the body by allowing the client to inhale some of the carbon dioxide she has exhaled, thereby alleviating the symptoms of tingling and dizziness. This method effectively helps calm the client's breathing rate and can provide immediate relief from hyperventilation symptoms.

While administering oxygen, notifying the healthcare provider, or checking vital signs might be appropriate in other contexts, they do not address the immediate cause of the client's symptoms related to the breathing technique being used. The focus here should be on correcting the breathing pattern to alleviate the hyperventilation symptoms.
