The perineal injury can be prevented in normal labour by all except:
**Core Concept**
Perineal injury during childbirth is a common complication that can be prevented with proper measures. The perineum is a region of skin and muscle between the vagina and anus, and injuries can occur during vaginal delivery due to prolonged second stage of labor, large fetal size, or instrumental delivery.
**Why the Correct Answer is Right**
Proper perineal protection during labor involves several measures, including **episiotomy**, where a small incision is made in the perineum to widen the vaginal opening and facilitate delivery. Another measure is **perineal massage**, which can help to reduce the risk of perineal trauma by increasing the elasticity and pliability of the perineal tissues. Additionally, **early recognition and management of fetal distress** can help to prevent prolonged second stage of labor and reduce the risk of perineal injury.
**Why Each Wrong Option is Incorrect**
**Option A:** Episiotomy is actually a measure that can prevent perineal injury during childbirth, not prevent it.
**Option B:** Perineal massage is a technique that can help to reduce the risk of perineal trauma during labor, making it a preventive measure.
**Option C:** Early recognition and management of fetal distress can help to prevent prolonged second stage of labor and reduce the risk of perineal injury, making it a preventive measure.
**Clinical Pearl / High-Yield Fact**
One key strategy to prevent perineal injury during labor is to avoid unnecessary episiotomies and instead focus on gentle, controlled delivery with proper perineal support.
**Correct Answer: A. Episiotomy is a measure to prevent perineal injury during childbirth, not prevent it.**
