There is one mistake that costs KRCHN candidates more marks than any knowledge gap: treating Paper II as easier than Paper I. It isn't. Here's the full breakdown — and how to approach both.
Understanding the KRCHN Exam
The KRCHN NCK exam has two integrated papers, each with 100 MCQs completed in 2 hours. Questions are scenario-based — you will be given a patient situation and asked what the nurse should do first, next, or most appropriately. The exam does not test memorisation. It tests prioritisation, emergency recognition, and safe clinical judgment.
Paper Structure for KRCHN
Paper I — Medical-Surgical + Midwifery + Pharmacology
- Medical-Surgical Nursing (30–35%) — common conditions, interventions, post-operative care, emergency recognition
- Pharmacology (20–25%) — drug classifications, dosage calculations, adverse effects, common protocols
- Midwifery & Maternal Health (15–20%) — antenatal care, safe delivery, postnatal care, obstetric emergencies
- Paediatric Nursing (10–15%) — common paediatric conditions, growth monitoring, immunisation
- Anatomy & Physiology (10–15%) — body systems, pathophysiology underlying clinical presentations
Paper II — Community Health + Mental Health + Professional Issues
- Community Health Nursing (25–30%) — health promotion, disease prevention, community assessment, PHC
- Mental Health Nursing (15–20%) — mental status exam, psychiatric conditions, therapeutic communication
- Environmental Health & Nutrition (10–15%) — water sanitation, waste management, nutritional assessment
- Research & Statistics (10–15%) — basic research concepts, health data interpretation
- Health Systems & Professional Issues (10–15%) — Kenya MOH structure, nursing ethics, legal frameworks
- Infection Prevention & Control (10–15%) — standard precautions, sterilisation, isolation protocols
These percentage ranges are based on publicly reported candidate experience. Confirm exact weightings with official NCK syllabus documents at nckenya.com.
The KRCHN MCQ Approach — ABCDE First
When a question asks what to do first, apply this priority order every time:
- 1Airway — is it patent?
- 2Breathing — is it adequate?
- 3Circulation — is perfusion sufficient?
- 4Disability — neurological status
- 5Exposure — other findings
This framework eliminates wrong answers in the majority of emergency scenario questions. It is not specific to NCK — it is the internationally recognised primary survey used in clinical practice (see ATLS/ACLS protocols).
Spaced Repetition: The Most Efficient Way to Retain KRCHN Content
The KRCHN exam covers a broad range of units. Spaced repetition — reviewing information at increasing intervals before you would forget it — is the most evidence-backed method for retaining large volumes of content. The SM-2 algorithm, which underpins NurseFiti's flashcard system, was validated in peer-reviewed research by Wozniak & Gorzelanczyk (1994) and subsequent studies.
How to implement it practically:
- 1After studying a unit, create flashcards for key concepts, drug names, and normal values
- 2Review new cards daily for the first week
- 3Cards answered correctly move to 3-day, then 7-day, then 14-day intervals
- 4Cards answered incorrectly return to daily review
