Clinical Scenario

A 33-year-old G3P2 at 32 weeks gestation presents to labor and delivery with painless bright red vaginal bleeding that began 2 hours ago — she has soaked through 2 perineal pads. She denies abdominal pain, contractions, or ruptured membranes. Obstetric history: 2 prior uncomplicated vaginal deliveries. A prenatal ultrasound 2 weeks ago documented a complete placenta previa covering the internal cervical os. Vital signs: HR 112 bpm, BP 100/64 mmHg (baseline 118/76), RR 18, SpO2 98% on room air. A

What You'll Practice

This NGN unfolding case study walks you through 1 linked clinical-judgment questions covering the full NCSBN Clinical Judgment Measurement Model. Each question is mapped to a specific cognitive layer; together they take you from recognizing the first cue at the bedside through evaluating whether your interventions worked.

NGN question formats in this case

The April 2026 NCSBN test plan rewards practice across multiple NGN item types. This case includes:

1× Bow-tie

Each format scores differently — bow-tie centers are all-or-nothing, matrix and cloze use partial-credit per row/blank, extended response is polytomous. Practicing the formats together builds the format fluency the exam rewards. See our NGN guide for the scoring breakdown of each.

Why this OB / Maternity case matters for the NCLEX

OB / Maternity content represents a meaningful share of the NCSBN April 2026 test plan, and unfolding case studies in this category test exactly the kind of bedside reasoning the exam was redesigned to measure. Working through this case builds the recognize-analyze-prioritize-act sequence you'll use on test day — and on every floor you ever work.

The single biggest predictor of NGN performance isn't memorization — it's pattern recognition built from doing many full case studies under realistic time pressure. Reading this scenario, predicting the first nursing action before answering, and reviewing the rationale afterward is the loop that wires the reasoning skill into your head.
