During which labor phase is the mother typically observed for hyperventilation symptoms?

• A. Latent phase
• B. Active phase
• C. Transition phase
• D. Second stage

Answer: (B)

The active phase of labor is the phase where the mother is typically observed for symptoms of hyperventilation. During this stage, contractions become stronger, longer, and closer together, leading to increased anxiety and discomfort for the mother. This heightened state can result in rapid breathing or hyperventilation as the mother may struggle with pain management and the intensity of contractions.

Hyperventilation can lead to a decrease in carbon dioxide levels in the blood, causing symptoms such as lightheadedness, tingling sensations, and anxiety, which can further exacerbate her experience of labor. Ongoing monitoring during this phase is crucial as healthcare providers can intervene to guide breathing techniques that help maintain an appropriate respiratory pattern, ensuring both maternal and fetal well-being.

In contrast, while hyperventilation might also occur in other phases, it is particularly monitored during the active phase because the increased intensity of contractions can exacerbate anxiety and potentially the risk of hyperventilation symptoms. The latent phase is generally characterized by less intense contractions, the transition phase involves preparing for the second stage of labor, and the second stage is focused on pushing, which may not highlight the same respiratory concerns.
