A primigravida at 41+0 weeks has Bishop score assessed as follows: Cervical dilation 0 cm (0), effacement 30% (1), station -3 (0), consistency firm (0), position posterior (0). What is her Bishop score, and what does it indicate?

• A Bishop score 2 — cervix requires mechanical ripening before induction
• B Bishop score 4 — borderline; oxytocin may be used
• C Bishop score 6 — favourable; oxytocin induction can proceed
• D Bishop score 1 — unfavourable cervix, pre-ripening recommended ✓

Explanation

Calculating Bishop score: Dilation 0 cm = 0; Effacement 30% = 1; Station -3 = 0; Consistency firm = 0; Position posterior = 0. Total = 0 + 1 + 0 + 0 + 0 = 1. A Bishop score ≤ 6 indicates an unfavourable cervix. Score < 6 requires cervical ripening (mechanical with Foley catheter, or pharmacological with misoprostol/dinoprostone) before oxytocin induction. A score ≥ 8 predicts successful induction similar to spontaneous labour.
