Understanding the KRCHN Exam
The KRCHN (Kenya Registered Community Health Nurse) NCK exam consists of two papers, each with 100 MCQs to be completed in 2 hours. The exam tests your ability to apply nursing knowledge in community and clinical settings — not just recall facts.
High-Yield Units for KRCHN
Based on past exam patterns, these units consistently carry the most marks:
Paper 1 — Community & Primary Health Care
Paper 2 — Clinical Nursing
The KRCHN MCQ Approach
KRCHN MCQs are scenario-based. You will be given a patient situation and asked what the nurse should do first, next, or most appropriately.
The ABCDE framework:
When a question asks what to do first, apply this priority order:
This framework eliminates wrong answers in most emergency scenario questions.
Spaced Repetition for KRCHN
The KRCHN exam covers a broad range of topics. The most efficient way to retain this volume of information is spaced repetition — reviewing information at increasing intervals just before you would forget it.
How to implement it:
NurseFiti's flashcard system does this automatically using the SM-2 algorithm.
