Which type of uterine dysfunction is associated with little pain but prolonged labor?

1. Hypertonic Uterine Dysfunction

2. Hypotonic Uterine Dysfunction

3. Both A and B

4. Neither A nor B

The correct answer is: Hypotonic Uterine Dysfunction

Hypotonic Uterine Dysfunction is characterized by infrequent and ineffective contractions that do not contribute significantly to cervical dilation, leading to prolonged labor. In this type of dysfunction, the contractions may be weak and spaced far apart, resulting in little discomfort for the laboring person. The absence of strong, regular contractions means that while the labor lasts longer, the individual may experience minimal pain compared to other types of uterine dysfunction, such as hypertonic, where contractions can be strong and painful, yet ineffective at progressing labor. Understanding this distinction is important for midwifery practice, as it allows practitioners to evaluate labor patterns effectively and identify when interventions may be necessary to support the laboring individual. Recognizing hypotonic dysfunction gives midwives the opportunity to implement strategies to enhance the effectiveness of contractions and facilitate progress in labor.
