What is the term for the separation found in the midline of the abdomen after birth?
- A. uterine subinvolution
- B. umbilical hernia
- C. striae
- D. diastasis recti abdominus
Correct Answer: D
Rationale: The correct answer is D: diastasis recti abdominus. This term refers to the separation of the rectus abdominis muscles along the midline of the abdomen. This condition commonly occurs after pregnancy due to the stretching of the abdominal muscles. It is important to differentiate diastasis recti from other conditions such as uterine subinvolution, which is the delayed return of the uterus to its normal size postpartum; umbilical hernia, which is a protrusion of abdominal contents through the umbilical ring; and striae, which are stretch marks caused by rapid stretching of the skin. Diastasis recti is characterized by a visible gap between the muscles, often causing a bulge in the midline of the abdomen. Treatment usually involves specific exercises to strengthen the abdominal muscles and improve the condition.
