Final Answer:
2) Modified-paced breathing
Step-by-step explanation:
In the first phase of labor, particularly when contractions increase in frequency and intensity, the nurse would typically advise the client to use modified-paced breathing. Modified-paced breathing involves taking slow, cleansing breaths to help the client manage pain and stay focused during contractions. This breathing pattern is designed to promote relaxation and prevent hyperventilation.
The other options describe different breathing patterns:
- Slow-paced breathing is generally used in early labor when contractions are less intense.
- The 3:1 and 4:1 pattern-paced breathing options are not standard breathing patterns recommended in labor support. Modified-paced breathing is a more common technique during the first phase of labor.
