A pregnant mother has a cervical dilation of 2 cm and less than 2 contractions in 10 min. This mother belongs to which among the following phases?

Appeared in: AIIMS Delhi NO-2016

Explanation

  • The patient's clinical signs, a cervical dilation of 2 cm and fewer than 2 contractions in 10 minutes, are characteristic of the latent phase of labor.
  • The latent phase is the initial part of the first stage of labor, where the cervix dilates from 0 to approximately 4-6 cm with infrequent and often irregular contractions.
  • Since the latent phase precedes the active phase, the most accurate description among the choices is 'Not in active phase'.

Why Other Options Were Wrong

  • Option A: The active phase of labor is defined as beginning at a cervical dilation of 4-6 cm or more. The patient's dilation is only 2 cm.
  • Option B: The late phase of active labor, or transition phase, occurs when the cervix is nearly fully dilated, typically from 8 to 10 cm.
  • Option D: This is not a standard medical term used to classify the stages or phases of labor.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Phases of the first stage of labor as background academic context rather than a clinical decision trigger.
  • Accurately identifying the phase of labor is crucial for providing appropriate nursing care, such as pain management, fetal monitoring, patient education, and determining the timing of interventions.
  • A patient in the latent phase is often encouraged to rest, stay hydrated, and ambulate. In contrast, a patient in the active phase requires more intensive monitoring and support.
  • What if? If the patient's cervix was 5 cm dilated with contractions every 4 minutes, she would be in the active phase of labor, necessitating closer monitoring of both maternal and fetal well-being and potentially more active management.
How to Approach the Question
  • First, identify the key clinical data provided in the stem: cervical dilation (2 cm) and contraction pattern (less than 2 in 10 minutes).
  • Next, recall the definitions and criteria for the different phases of the first stage of labor.
  • Compare the patient's data to the standard criteria for the latent phase (dilation 0-6 cm, infrequent/irregular contractions) and the active phase (dilation >6 cm, regular/frequent contractions).
  • Determine that the patient's findings match the latent phase.
  • Evaluate the given options. 'Not in active phase' is the most accurate description for a patient in the latent phase.
Concept Tested & Keywords
  • Concept Tested: Phases of the first stage of labor
  • Stem keywords: pregnant mother, cervical dilation, 2 cm, contractions, 10 min
  • Lead-in keywords: which among the following phases
  • Clinical cues: Cervical dilation of 2 cm indicates an early stage of labor.
  • Clinical cues: Fewer than 2 contractions in 10 minutes suggests infrequent uterine activity.
