A client in labor is assessed, and the nurse determines that her cervix is dilated to 5 cm and is 80% effaced. The client is experiencing strong contractions every 3-4 minutes. Which phase of the first stage of labor is the client in?

1. A

   Latent Phase

2. B

   Active Phase

3. C

   Transition Phase

4. D

   Second Stage

Explanation

Listen in Hindi

• The active phase of the first stage of labor is defined by cervical dilation from 4 cm to 7 cm.
• The client's cervical dilation of 5 cm falls squarely within this range.
• Furthermore, the contractions are strong and occur every 3-4 minutes, which is the typical pattern for the active phase as labor intensifies and progresses more rapidly.
• Effacement of 80% indicates significant thinning of the cervix, which also occurs progressively during the active phase.

Why Other Options Were Wrong

• Option A: The latent phase is the earliest part of labor, characterized by cervical dilation from 0 to 4 cm. Since the client is already at 5 cm, she has progressed beyond this phase.
• Option C: The transition phase is the final, most intense phase of the first stage of labor, with cervical dilation from 8 cm to 10 cm. The client's dilation of 5 cm is not advanced enough for this phase.
• Option D: The second stage of labor begins only after the cervix is fully dilated to 10 cm. The client is at 5 cm, so she is still in the first stage of labor.

Clinical Relevance

• Nursing practice connection: Use the key finding related to Identification of the phases of the first stage of labor based on clinical assessment findings to guide bedside assessment, documentation, and the next nursing action.
• Correctly identifying the phase of labor is critical for the nurse to anticipate the client's needs and provide appropriate care.
• During the active phase, nursing priorities include more frequent monitoring of maternal vital signs and fetal heart rate, effective pain management (e.g., epidural analgesia), providing comfort measures, and offering encouragement and emotional support as contractions become more intense.
• What if? - If the client's cervix was 5 cm dilated but contractions were mild and 10-15 minutes apart, the nurse might suspect a prolonged latent phase or hypotonic uterine dysfunction, which would require different interventions, possibly including augmentation of labor with oxytocin.

How to Approach the Question

• First, identify the question type. This is a clinical scenario question that requires you to apply knowledge of a physiological process (labor) to a specific patient case.
• Next, carefully read the stem and extract the key clinical data points: cervical dilation (5 cm), effacement (80%), and contraction pattern (strong, every 3-4 minutes).
• Recall the definitions for the stages and phases of labor. The first stage has three phases: Latent (0-4 cm), Active (4-7 cm), and Transition (8-10 cm). The second stage begins at 10 cm.
• Compare the client's data to the definitions. The cervical dilation of 5 cm fits the criteria for the Active Phase.
• Evaluate the contraction pattern. Strong contractions every 3-4 minutes are also consistent with the Active Phase.
• Based on this match, select 'Active Phase' as the correct answer and eliminate the other options because the client's dilation is too advanced for the latent phase and not advanced enough for the transition or second stage.

Concept Tested & Keywords

• Concept Tested: Identification of the phases of the first stage of labor based on clinical assessment findings.
• Stem keywords: labor, cervix dilated 5 cm, 80% effaced, strong contractions, every 3-4 minutes
• Lead-in keywords: Which phase
• Clinical cues: Cervical dilation of 5 cm is the key indicator that places the client beyond the latent phase.
• Clinical cues: Strong contractions every 3-4 minutes confirm that labor is well-established and progressing, consistent with the active phase.
