OBG Nursing for NORCET: High-Yield Topics, MCQs | NPrep

Obstetrics and Gynaecological (OBG) Nursing, or Midwifery, is one of the most important NORCET subjects. In NORCET 10 Prelims it gave about 14 of 100 questions by candidates' recall, second only to Medical-Surgical Nursing. Expect labour, postpartum haemorrhage, pre-eclampsia, newborn care and family planning, mostly as clinical scenarios.

Updated 5 November 2026. The exam pattern is from AIIMS Notice 103/2026. Question counts are NPrep's analysis of the NORCET 10 Prelims paper as recalled by candidates; AIIMS publishes no subject weightage. Clinical facts follow standard obstetric textbooks and Government of India guidelines.

How many OBG questions come in NORCET?

AIIMS publishes no weightage. In NORCET 10 Prelims, candidates recalled about 14 OBG questions out of 100. Together with Medical-Surgical Nursing (about 23), OBG made up about 37 of the 100 questions, nearly half of the 80 nursing questions. Stage II has 160 nursing questions focused on case scenarios, and obstetric emergencies suit that style well, so give OBG your second-largest share of study time.

What does a NORCET OBG question look like?

NORCET 10 asked this kind of question:

A pregnant woman on magnesium sulphate therapy is being monitored. Which finding indicates magnesium toxicity?

A. Deep tendon reflex +3 B. Fetal heart rate 138 a minute C. Respiratory rate 17 a minute D. Urine output 10 mL an hour

Answer: D. Magnesium is cleared by the kidneys, so low urine output lets it build up. A +3 reflex is brisk, not absent, and the fetal heart rate and respiratory rate are normal. The trap is option A, because reflexes are the classic toxicity check, but toxicity shows as a lost reflex.

How should I prepare OBG for NORCET?

1. Learn labour and emergencies first. They carry most scenario questions.
2. Make a drug sheet for oxytocin, magnesium sulphate and methylergometrine: dose, monitoring, toxicity and antidote.
3. Solve 30 OBG questions a day in the months before Stage I, and review every wrong answer.
4. Revise newborn care with Child Health Nursing, because the topics overlap.
